I found FLI as a gold COBB protuner. I had some intake updates on my Evo X and wanted a tune to go with it. I do most of my driving on the track in this car and high-RPM performance is important to me. FLI's Miles helped me to iterate on the tune, add an injector package and get the performance I was looking for. Awesome job. They also installed some missing panels for me which saved me a lot of time. Great guys, love cars and love racing. read more

See all

Worked with the owners Ryan (no longer there, sad to say) and Miles for some years before moving away. They helped me get my Subaru from stock to stage 3 tuned by being their 1st customer for a Jackson Racing supercharger install. Aside from a few miscommunication instances with various things, their service was excellent. Very knowledgeable and willing to walk you through the process. I know some other places who certainly aren't as knowledgeable and won't bother with you if you don't already know what you want. I always recommend them for whoever is in the bay area. read more

Miles and the team pay such great attention to detail. They made me feel like my car was in the right hands when they worked on it. You can trust Fine Line to follow through with excellence! read more

These guys are pros. Alonzo seems to approach a more pragmatic solutions for tune ups and car issues.

Miles and his team do some great work! Very knowledgeable and extremely professional and helpful!

If I could give more stars I would. My store is very close Fine Line and I have never seen American cars being worked on there, but I know Miles and the guys pretty well. A year ago I purchased a 1967 Plymouth Satellite resto mod and I knew there were a few things that I wanted to change and upgrade so I went to Miles for advise. We put it on the lift and looked it over and made a list of things we wanted to repair and modify. To make a long story short, These guys identified and repaired things that I didn't see and did the repairs in a much better fashion that I even knew about after spending 20+ plus years as a mechanic. The craftsmanship and quality of their work is absolutely second to none. I could fill a page with praise of what they did and how awesome it is. I have the car back and while it was a huge undertaking that took about 6 weeks and we still have some minor tweaks remaining it is much better workmanship than I expected. Communication thru the entire process was incredible and I knew exactly what was happening. You will never find a better repair shop and I am VERY hard to please when it comes to cars. Thanks guys!!!!!!!!! read more

I've got an aging Subaru WRX that needs some TLC, and the guys at Fine Line have continually exceeded my expectations. No upselling, great advice and planning for extended care, and overall just a fantastic environment with knowledgeable people. I trust their work, and the shop rates are incredibly reasonable for the level of service they provide. There are few places I can have a candid conversation about saggy butt spacers where I'm not immediately asked to leave, and FLI is one of them. I'll be taking my car to FLI while it's still running, which, as it turns out, will be quite a while thanks to Fine Line! read more

When I decided to get a custom tune done on my '07 Subaru WRX Wagon FLI was recommended to me. The crew there got me scheduled in a timely fashion and did an excellent job. We augmented a stage 1 tune using my Cobb Accessport as a starting point, making some custom tweaks and taking advantage of the GReddy catback exhaust on my car. The end result is a noticeable increase in the car's low and midrange power. I wouldn't hesitate to bring my car back to FLI for any performance-oriented upgrades. read more

I love this shop and I love ANDREW! He's seriously the best. As a lady Subaru owner, I haven't always gotten the best service, but I am happy to say that is NOT the case at Fine Line. I appreciate the time they take to talk to me about what's going on with my car and I always feel like I can trust their word and work. This is the only place to take your wrx/sti! read more

Everyone we dealt with was great, helpful and kept in contact for progress. Trust worthy. Excellent.

On my first visit, I met both Jasons, Andrew, Ryan (co-owner) and Miles (the other owner). They were all very friendly and professional. Ryan gave me a tour of their entire shop, then we created a map for the road I will be taking with future upgrades. I continue to experience great customer service. Found my shop! read more

I've brought a couple cars to them. They helped me diagnose a failed head gasket on an '08 WRX and Miles recently helped me get my '05 Outback smog ready on time and WAY under budget. It passed smog a couple days ago. Couldn't be happier. read more

I brought my 350Z here last month for a dyno tune and I am more than satisifed. Previously my car has been upgraded by Z Car Garage but I wanted to find a new place since Z Car is always busy. FLI is known as a Subie tuner but I did my research and all my questions were answered before I made a commitment. Getting here was a a distance; Union City to Santa Rosa. So my expectations were high. Any issues would mean another road trip, so was hoping everything would work out as planned... and it did! Miles was easy to deal with and he was very thorough and explained my new tune with detail. I am happy with my +15 hp/tq gains! ....And to top it off, I passed my smog test! I will likely bring my Z back when I add more performance mods. Thanks!!! read more

Excellent, Job. They specialize in Subaru's. I can't say enough about Ryan and Miles. These guys rock. They know what they are doing, and do it well. The prices are fair, and they will take the time to explain to you what is going on and what they are going to do to fix it. These guys love Subaru's and I don't think I will take my car to the dealership after the top notch job these guys throw down. read more

Look no further for your Subaru needs, especially if you plan on modding. FLI is compromised of a knowledgeable and friendly staff that go above and beyond to meet and/or exceed the customers expectations. Andrew and Miles are awesome. Andrew answered all my questions and was thorough with explaining how my service would be completed. Miles took extra time out of his day to go on a test drive with me and fine tune my map. Solid guys and solid shop. read more

Just wanna give a big big shoutout to Miles, Daniel and their crew for taking care of my rear diff that needed to be replaced. Big shoutout to them for taking their time and effort. I highly recommend them if you have any problems with your car or tryna gain more horsepower aha. But thanks again Fine Line Import!. read more

Took our Subaru in for a through looking over as we wanted to determine if we were going to sell or keep it. Charged $110 by fine line who basically did nothing. My husband found the oil leak and had to ask if they had tested the battery. They had done neither of theses. When he wondered why they charged him but hadn't done the job, they actually threatened him! Would never use this place again. read more

Employees are very knowledgeable in what they do. Great attitude and great customer service. Definitely worth the drive!

TL;DR: FLI is awesome, had them do a lot of work, and my car will never go anywhere else. I first brought my car here about 6 years ago. I had managed to blow the motor in my beloved Subaru after only owning it about 6 months. I shopped around asking for quotes from multiple Subaru specialists in the bay area. I wasn't worried about taking the car far from home in order to get top quality work. I was stoked to find that FLI was not only local, but had a great reputation and customer service. I stopped in multiple times before having any work done on my car. Ryan was happy to answer my constant barrage of questions regarding pricing and additions of aftermarket parts, many of which came before I'd even spent a dime with them. They rebuilt my motor with a brand new OEM short block, machined my factory heads and added on a few modest upgrades, and managed to stay within budget. I was beyond ecstatic to have my baby back on the road again! In the years since my rebuild I've done multiple upgrades to the car. Of course I had the car tuned by Miles at FLI. My car has managed to be a reliable daily driver while making decent power. I've managed to put nearly 100,000 miles on my rebuilt motor and currently running a Stage 3 tune. I trust my car to do what I need it to and I trust FLI to keep it that way. Did I shop around for better pricing on oil changes and parts installations over the years? Yeah I did, and I took my car a few other places to have minor things done. Unfortunately, I ended up regretting taking my car elsewhere every time. While living in southern California I took my car to another highly regarded Subaru shop to install some new parts, I was pretty dissatisfied with their service. I ended up scheduling oil changes and other services to co-inside with visits with family, just so I could take my car to FLI. Fine Line Imports is now the ONLY shop allowed to service my vehicle. Will other shops perform services for cheaper? Probably, but in my experience you get what you pay for and FLI is definitely top notch. I'm stoked to be able to take my car to a shop and trust that it's in good hands. read more

Although FLI is known as the premier Subaru tuning destination, I brought in my '98 Volvo S70 T5 Turbo for offset and suspension tuning (Eibach Spacers, Koni Adjustable Suspension) and maintenance (Red Line Oil, genuine Volvo factory parts). I have historically known Miles through my Import Car crew, Z.Team Yossi, and Miles is one of the very few stand up guys with a sincere heart and a desire to tune a motor vehicle to its maximum potential. The FLI team is one and the same - it's rare to experience in the automotive tuning world where shops come and go with poor reputation. The FLI reputation precedes them. You cannot find a finer AWD dyno tester and tuner. Miles doesn't bullzip and beat around the bush, he will stand by his experience and decades of high horsepower import car tuning wisdom. I've driven cars like the Mitsubishi Lancer Evolution, Skyline R32 GTR, JDM Civic Type R, Integra Type R, Twin Turbo Supra's, 500hp Single Turbo RX-7, 400hp Twin Turbo 3000GT, amongst a plethora of finely tuned import cars. Yet, when I was given the opportunity to test drive FLI's award-winning flagship Subaru WRX street tuned race car at the local naval base, I was nearly tearing in the eyes, from joy, due to the disbelief that a car could be so finely and sharply tuned. FLI is the real deal, with history back to 1996 and 100% backing from Z. Team Yossi. read more

Fine Line Imports - A view of the all wheel drive dyno tuning room and shop signage. - Auto Repair Near Me - Santa Rosa, California

Fine Line specializes in Subaru's. I highly recommend going here. The prices are fair, the people absolutely rock, and they do a terrific job on my Subaru every time. It's also fun to go there because you see lots of WRX's! Check it out read more

Honest mechanic and shop, what better could you say, its clean as a hospital. I've been going to FLI since before they had this location, they have worked on all four of my cars actual more but I have sold a couple of them to buy Subarus,the world class mechanic Steve drives a Legacy sedan Ryan the salesperson drives a Forester and Miles the great, tune & dyno-specialist has a WRX I bought my daughter Jennifer a Forester used and Steve went over with a fine tooth comb shes still driving w/180k mi I bought my other daughter Laura an Acura Steve recommended from another customer and shes still driving it! Last year I purchased another Subaru Impreza R/S after the guys looked it over and I couldn't be happier.. if you want to contact me personally I'd be happy to go on and on. donofnca@gmail.com Don M. read more

I don't know what happened to the first review I left but they must've figured a way to get it taken down... Punks. I see all the great reviews... That was not my experience. They took on my job but when everything went wrong and the ball landed In their court, they walked away with their hands in the air and this to say "I didn't do it". How else if the radiator hose going to blow off the day after your shop flushed it? Well I ended up with a blown headgasket 2 months later. I can only think that they were to blame. NO NOT GO HERE. Everything is all fine and dandy... Until they screw your car up and then they're your worst enemy. How ya like me now???? read more

This place is great! I had a shop install a Procharger on my G35, yet they had no clue how to tune it. They just gave my the car back and said don't step on the gas to hard you could blow your engine. So I called around to a few shop and found these guys. They said this type of job was right up there alley. I dropped my G off and two weeks later I had 95 more whp with a few maps. Perfect tune! These guys really know what they are doing. Great shop will go back for future mods and when I get my next tuner. They say I have 335 whp but it feels like 400. Half throttle and my G is sideways. Great shop!! read more

I believe FLI is an outstanding shop for dyno-tuning, and Subaru mechanical. Unfortunately, I would not recommend them for custom work on other makes how ever. When planning my project car, I bought a Link G4 ECU from Miles. Once I got the car to a certain point I brought my SR20DET swapped Datsun 510 to FLI to have the ECU, and new s13, (E5 ECU) Wiring Specialties engine harness installed. I also hired them to install the fuel lines to and from the fuel cell, regulator and rail. The intent was to get the car running and tuned so I could finish the rest of the build. Along the way I was told that the brand new harness I had was a mess and needed to be torn apart and fully tested. During testing they reported the $500 ignition chip was fried, but months later said it was OK. All of this took a huge amount time (over a year in fact) and cost 3X their original estimated. I asked Miles on several occasions to contact Yury at wiring specialties so he could help them figure out the problem, but time and time again Miles refused. In the end we had spent over $12,000 on FLI's work, but they still hadn't got the car running, or tuned. They assured me they would have it running by a specific date, but then reported the #1 cylinder had a leak down of 80%, which meant the engine was shot and needed to be replaced. I knew this cylinder had a compression of 170 psi. when I tested it, so I felt this didn't add up. I asked Miles to start the car so I could see what it was doing, but he refused saying it would damage the engine. I immediately took the the car to another shop who found the ECUs fuel map for the 1000cc injectors were off by 300%, the engine ground wire was left disconnected, the starter wires were only finger tight, fuel lines were leaking, and they found a foreign metal object in the #1 cylinder. 20 minutes after pulling into this shop, the car was running smoothly on all four cylinders with no smoke at all. Almost two years later now, the car is boosted to14 psi. and still running strong today. In the two years sense I've found many other issues. I also discovered the real reason they were having so much trouble with the wiring harness. FLI had re-pinned a bunch of wires on the harness ECU plug and gave me a printout of the plug showing the changes they made. When I compared these new pinouts to a s14, J5 ECU pinouts they matched, and it was obvious they had uploaded the wrong base map to the Link ECU. Instead of confirming the map and correcting it, they blamed Wiring Specialties' product and spent hours blindly testing, taring it apart, and reconfiguring the harness so it would fit the wrong map. Had FLI uploaded the correct map and followed the instructions on the bag, it would have taken only four wire splices to hook the harness up and get the car running. I believe FLI's intentions were good, but they sold a job they were ill equipped to do. Unfortunately they quickly found themselves in the unfamiliar territory of being in over their head, and not knowing what to do. I think Miles and his crew are very good at what they know, and I don't think my experience is the norm. It is still a very bitter pill to swallow to have gone through all this without so much as "I'm sorry" from anyone at FLI.. read more

I brought my '07 WRX to FLI originally back in 2011 and it has not been to another shop since. Ryan and Miles have always made me feel like a VIP customer. I am very particular and detail oriented with my car and I never feel like I am wasting Ryan's time while we have spent hours upon hours discussing different parts, direction for the car, or life in general. They are genuine good guys and on top of that they have helped guide me on my quest to have a unique build with nothing but high-end quality parts like Tomei, Cosworth, Cusco, Aeromotive, Killer B, AST Suspension, VIPEC Link ECU, etc. My car has evolved from a mild VF39 street car to a stripped out fully built track car. Any time I want to make any small changes to the tune, regardless of how small, Miles is always willing to hop in and take a spin for some street tune adjustments. Miles' tuning style is conservative and aimed for longevity, drivability and reliability- which is just what I want when running the car hard on the track after spending $$$$ on my engine. I am currently in the break in process with the latest build (closed deck block, built STI heads, Blouch Dom 2.5) and look forward to the final results after a few more miles. Next will be installing the stockpile of STI drivetrain parts I have in the garage... If you are in the Northern Bay Area I wouldn't think of going anywhere else. read more

The guys at FLI are amazing, so professional and really knowledgeable. I don't have a fancy car, but I wouldn't take my Subaru Impreza anywhere else, they know what they are doing. read more

Always bring my Subaru there for everything. They are the best, Honest and reputable which is important to me.

Quick turn around time and good work done. They explained everything to me and were very helpful with what was needed.
