ATP -4 size oil inlet fitting for GT30R and GT35R

I've had a set of silvers on my c5 for about 4 years now, picked up another for my c6. Zero complaints, night and day difference over the factory worn out shocks and leafs. Perfect for a daily.

One of many parts I ordered with the help of fi performance. Came in asap and was better quality then expected.
Brian’s been a big help with getting my car up and running right.

I have ordered multiple times from this outstanding company. I will continue to do so. Customer service and communication is top notch and they have a wealth of knowledge.

Great quality, unfortunately the differential did not make the pass , time for an uprgraded diff lol

Brian was able to help out in a pinch and got me this MPVI 3 out the door in no time. Couldn’t be more happy with the price point and customer service. I will be purchasing from Brian again. Thanks fiperformance.

Very happy with the product

I want to give a shout out to Brian Rosenberg! He answered my post asking for a coilover that would ride at factory height due to my large dip in my driveway and something that wouldn’t rattle my future dentures out! Placed order Thursday morning, received Friday on my UPS delivery and installed yesterday! They felt great on the short trip home. Took the bounce out but not harsh across the RR tracks. I did some spirited interstate driving this morning and back to being excited about driving the car again!
It’s a 2010 GS with A&A charger and tuned A-6 with a 2.73 diff riding on Michelin 275/18 PS 4S fronts and Toyo 345/19 r888r rears. One day I might swap for lower gears but I enjoy highway cruising and doing 80-90 under 2k RPM! I can’t wait to move and get a flatter driveway so I can drop the front to match the rear!
The A&A kit drops the radiator support one inch so it tries to drag off coming out of my driveway! I even have the rollers installed!
The VMS lowering bolts were noisy due to the delrin flaking off in less than a year and little miles😡I was hesitant to install coilovers because everyone told me they would be harsher than the leaf spring. I purchased the Johnny O’Connell shocks and sway bar kit. If anyone has need for slightly used shocks I have a set!
Anyway, if you are on the fence about coilovers give Brian a shout! It was the easiest and best transaction I have done yet with any of my vehicles including building my Diesel Wrangler as well as my two Duramax trucks! Sorry for long winded post! I just know getting good service in today’s times has been non existent!
Thanks Brian

Brain was able to help me out in a tough situation. I need an HP tuner asap and he provided exactly that. I received the MPVI3 in a super timely manner and couldn’t be more happy. 100% will do business with Brian again.

Exactly what i needed ! And super fast , professional service! Will be using this vendor again for future products! 10 star rating if it were possible !

Brian is the man when it comes to parts. Very knowledgeable and helpful. If you have a question he is fast to respond and is always willing to help. Awesome customer service.

Love the way it rides and stance looks great

One on one customer support from a fellow gear head. You can't ask for much more.

Thanks for the help in the radiator. Got to get her installed asap n

I received my new radiator for the C5 Corvette. It looked great. I was missing the zinc stick that was supposed to come with it, but FIP got that out in the mail to me and it got here in time to be installed with the radiator. It is now in the car and working beautifully!
