    Malek & Fred showing me my old rod bearings.
    Darren S.

    MRF Engineering is straight up the best mechanic shop I've been to in my life. No questions. Let's start from the beginning of my experience. When I called Malek from MRF Engineering to setup my appointment for a Rod Bearings service on my E92 M3, Malek sent me a very detailed email about the entire process. How long it's going to take, the cost, what parts and fluids are they using, etc. Made my appointment then went to MRF in the morning and was greeted and welcomed by Malek's father, Fred. He explained to me how everything is going to go down, showed me around the shop, showed me what rod bearings even are, and showed me what an engine looks like after rod bearings failure. I felt like a valued customer the entire time and the shop is extremely clean and organized! Left my car there overnight to pick it up the next day and met Malek. Malek showed me my old rod bearings and explained to me everything about them. Also gave me a run down on the condition of the rest of my car. He then answered all of my questions very patiently and was very detailed about each answer. Overall the entire experience was smooth and vastly exceeded my expectations. I would 100% recommend anyone to bring their beloved M3 to MRF Engineering after my experience here. Thank you Malek and Fred!

    What a transformation! The M3 feels much more buttoned down. Everything from shifting to bump compliance to sliding feels more engaged. Listen to Malek and take his suggestions. I doubt anyone on this continent knows the E9X platform better. I would write more but I need to keep driving!

    Phenomenal! Malek has replaced the engine in my 2009 M3 in April of 2017. I took it down there from the Bay Area on a trailer and I continue to make the drive out to him for maintenance/upgrades. MRF is California's true leader for M3 rod bearing service with over 270 cars completed successfully. He also installed Bilstein Clubsports, BBS E88, and a bunch of new suspension components on the car. I consider MRF my family. The only place I trust with my cars, hands down. Thank you!

    Came in for a PPI on an F87. I really appreciate how prompt, fairly priced, and professional the overall experience was.

Insurance was covering, so price really wasn't an issue dor me. They aren't cheap, but they do amazing work. Turn around time was laid out in front of me, and they met the goal. It was a LONG process (read 1.5 months); if I didn't have a provided rental it may have affected my rating, but I did have one. Everything with the insurance process, getting me to/from the rental location, communication with me and the adjustor, and workmanship were all top notch. Ran into some issues on first attempt at a pick up, but they rectified it with fixing the issue, as well as transportation and delivery to the Irvine location. I then had wheels installed at the performance shop in Irvine. Again, it wasn't cheap, but they met all expectations. Shout out to Issa, Luis, Josh and all the of the SSR team that worked on my vehicle. If owners of high end luxury cars and supercars trust SSR, you should to. (If you have a luxury of super car that is.)

They don't just do the job--they make sure you walk away completely satisfied. Huge shoutout to Arnold and his team for being so professional and delivering such amazing work. This is actually the second car I've brought to them. They did clear PPF on my first car eight years ago, and it still looks perfect--no yellowing, no peeling, nothing. That's why I came back, and once again, they exceeded my expectations. This time they wrapped the antenna, roof, spoiler, and mirrors in black PPF, did the full front end in clear PPF, and added black vinyl to the lower side door molding, rocker molding, and rear trunk molding. The cuts and edges are incredibly clean. If you're thinking about PPF or vinyl wrap, you won't regret choosing Aerowerkz.

I mentioned wanting to do other mods to my car, including an air intake and catback exhaust. They took care of that as well by ordering and installing the parts for me. I even got some exterior parts myself (new grill, front lip splitter, air duct inlets), and they installed that as well! They even decided to put a rush on installation when I requested it. Whatever I wanted, they made it happen. Needless to say, the crew at Aerowerkz do amazing work. They have great attention to detail, are communicative, and care about the quality of their work. Turned my car into something I never could have imagined it. Shoutout to Jorge for helping me out thought the whole process! If you need work done to your new car (e.g., PPF, tint, exhaust, body kits, etc.), come to Aerowerkz. You will not be disappointed at all.

    "READ THE 1-STAR REVIEWS FIRST - FATAL SAFETY FAILURE" I…read morechose Rebel Off Road because I trusted their professional image and public reputation, but what I experienced was shocking, stressful, and completely unacceptable. Throughout this situation, I tried to remain professional and respectful and expressed my willingness to resolve everything amicably. Yet, after paying nearly $4,000 for a re-gear service, I discovered a massive gear oil leak covering my driveway the very next morning due to an improperly secured axle. This left my driveway stained and reeking of gear oil--with professional cleaning estimates ranging from $400 to $600--and I spent the entire weekend in anxiety, questioning whether my truck was even safe to drive, and eventually having to return it on Monday, which disrupted my business. During this process, I was communicating with my assigned service advisor, but responses were often delayed, unclear, or evasive; messages went unanswered, questions were redirected, and clear answers were difficult to obtain. When I brought the truck back, it was described as "just a loose axle" and claimed fixed, yet no documentation was provided proving that the differential or internal gears were inspected after I had driven it for an hour while leaking. Their claim that "there is no problem" or "everything is fine" is something no reasonable person could trust. With re-gear work, any mistake or improper setup often only becomes apparent after several thousand miles of driving. This is why a formal guarantee is not just a request, but a necessity. When I requested a formal written warranty, they only gave me a $0 invoice with no actual warranty terms or duration. For days, I calmly requested two very reasonable things: a formal written warranty and a fair resolution for the driveway damage. I never demanded compensation for emotional distress or lost business time; I simply asked for accountability. After experiencing this, I looked through other reviews and realized that my experience was not an isolated incident. I strongly urge everyone to READ THE 1-STAR REVIEWS FIRST before coming here. You will see a chilling and habitual pattern: dodging responsibility, being 'afraid of standing behind their work,' and sneakily adding extra charges--then claiming they are unavoidable. In fact, I later realized the overcharge I experienced was just a small fraction compared to what others have reported. You will also notice that the owner's responses to negative reviews are always the same--robotic, defensive, and dismissive. They publicly ask customers to 'contact us' to give the appearance of being helpful, but it is nothing more than a deceptive marketing tactic. If they truly intended to resolve these issues, my driveway wouldn't still be stained, and I wouldn't be left with a useless $0 invoice instead of a real warranty. The fact that these 1-star reviews remain unchanged proves that their 'invitation to talk' is a sham and nothing ever gets resolved. They have a template for excuses but no manual for accountability. I am sharing my experience and my filing with the Bureau of Automotive Repair (BAR) so that other victims know there is a formal way to seek accountability. After seeing so many similar complaints, I strongly encourage anyone who has had similar experiences with their safety, property damage, or deceptive billing to file a formal complaint with the BAR as well. As a business owner for over 20 years, I understand mistakes happen, but I cannot accept a refusal to take responsibility. I am now filing a formal complaint with the Bureau of Automotive Repair and initiating a credit card dispute. A strong online presence means nothing if a company fails to protect its customers' safety and property. [UPDATE: Response to the Owner's Reply] The owner's response below is exactly what I warned about: a robotic, defensive excuse that shifts the blame. They claim a 'failed C-clip' on an aftermarket part, but as any professional knows, this is a clear sign of improper installation, not a part failure. They also claim they 'verified' no internal damage, yet they provided zero technical proof or a detailed inspection report after I drove with no oil for an hour. Mentioning a '90-day warranty' now is laughable--if that were true, why did they refuse to provide a formal written warranty when I asked for it repeatedly for days? Their response is just another marketing tactic to look responsible in public while remaining unaccountable in private. My filing with the BAR and the credit card dispute will proceed as planned.
