These guys are legit. They really know their stuff and helped us fix the problems on my brother’s 04 sti! Nowadays its hard to find a trustworthy auto shop, but I trust these guys 100%!

I’ve tried probably all of the subaru performance shops around SoCal and after finding Prolific, I would never trust my car anywhere else. Frank knows everything subaru, gives very fair prices for high quality work, and is a supremely straight no-​BS kind of guy.

Installed Perrin AOS on 2015 STi, the right way. Frank is clearly knowledgeable in his craft. Final result is impeccably clean and looks OEM like. Despite the shortcomings of Perrin’s package, Frank took his time and filled in all voids left by Perrin, and did it all with a generous bill.
Very satisfied, will be returning! A+

Spoke to Frank about installing a boost gauge. He was able to accommodate a last minute appointment, which I appreciated. He was very personable and easy to talk to. Answered all my questions.
I definitely recommend this shop for all your minor or major projects.

Called up prolific for a clutch replacement on my 13′ WRX and not only did I get a great price but I definitely got the VIP treatment from Frank. Along with the replacement he completed of variety of other tasks the car needed and ensured everything was top notch before completing the install.
Prolific has found themselves another lifetime customer.

Frank at Prolific Autosport was a pleasure to deal with, and he’s an honest, caring, genuine human being. And he’s a USMC veteran!
I was moving out of CA and Frank made sure my two Subaru’s (both modified) were up to the task of a cross-​country relocation. This included an engine rebuild for my WRX wagon and a 105k service for my wife’s lowered Outback. With Frank, we’ve had oil changes, axle replacements, brake modifications, and general consulting.
About the only downside I can think of is that, when I lived in CA, his shop in Upland was pretty far from my home in Tustin. Other than that, good dude, good shop, highly recommended for anyone who need general maintenance or full on race builds for their SoCal Subaru cars. :)

Took my 06 WRX for clutch, flywheel and SS clutch line replacement. Couldn’t be more pleased, Frank and Manny took care of my car as their own. Definitely returning and referring to my Subaru buddies. Great shop and experience overall. THANKS!!!

Very good place to bring in your Subaru for maintenance or engine build. They staff here are well known in the Subaru industry. The knowledge base of the mechanics here met my expectations to the fullest. Great place to bring your car and have piece of mind that the car will be taken care of. There are no corners cut here and they will offer great advice on what to do to get your car back running. No frills no trickery here. Stop by and check this place out especially if you are in the area. I would give 10 stars if I could.

There is no other place that will touch any 3 of my Subarus. I’ve been in the subie game for a while now and now an excellent shop when I see one. Frank is the man and definitely knows his stuff. Superior customer service, amazing affordable pricing and hospitality like no other (Even my girlfriend who arrived there before me was met with such hospitality). Prolific will and always be my go-​to shop for anything for my Subarus. (I own a 2004 STi, 2000 v2 EJ20G swapped RS2.5 and 1993 Impreza L 1.8L).
