Let customers speak for us
Brian”s great! Fast shipping great communication.
smooth ride even bottomed out, Brain does great on his customer service
Fit perfect
THIS IS AN AWESOME COMPANY TO DO BUSINESS WITH, THEY ARE VERY PROMPT TO TAKE CARE OF YOUR ORDER AND THEIR PRODUCTS ARE THE VERY BEST. AWESOME JOB!!!
I've tried 3 different diff mounts. The Lux Mount by SacCity, AMT Double Barrel, and just for the **** of it the Duralast c5 mount. Finally bought this 954 Bullet from FI Performance. In a nutshell the 954 had the least NVH of them all and best of all zero wheel hop even with crappy tires. Thanks Mr. Brian for your vast knowledge on this subject.
I purchased this kit and the install was fairly straightforward, the quality of the kit is amazing!!! Made a very noticeable difference in tightening up the entire suspension, and I did not notice an increase in NVH.
I can't say enough about silvers and brian. I recently got into an accident that broke one of my coilovers. Brian immediately reached out to his people and got me a single coilover. You can't go wrong with silvers or brian.
I am well pleased in choosing brian and crew for my coilovers. They have been very helpful and got me my order right away.
worked perfect. Install was a breeze! everything was great! Except for the waiting period due to transitioning. maybe next order will be super quick. Thanks Brian for keeping in touch.👍🏼
These are by far a major upgrade over stock the oem rubber mounts couldn't take the abuse and shredded leaking luid all over the engine bay and leaving my engine flopping the amt mounts are a mix of metal on the outside and inside and a hard rubber "bushing" in the middle giving you the best of both worlds and making it durable and everything tighter very easy to install and torque down looks better and definitely feels better very minimal increase in noise and vibration but not enough to really notice or effect everyday driving a must have for higher horsepower applications or if you just beat the **** out of it.
This is a high quality 3D printed guage mount that is installed and replaces the driver's left side heat vent to mount your gauge to and it will still blow air through it without any issues as it's vented on the top and bottom it installs very easy and fast and will fit multiple different gauges and is very sturdy and strong if you have a AEM guage this is not the correct mount they make a specific mount for the AEM gauges.
This bracket is for the c6 corvettes with the Z51 package only not the Z06 they have different coolers and therefore different brackets with that being said this bracket works fantastic definitely when using it with the A&A supercharger kit and don't want to delete your oil cooler like me and so this allows you to move your cooler to a different location and out of the way and still be able to use it with the supercharger.
I upgraded to the four piston Wilwood calipers on the front and rear of my C5 Z06 and boy what a huge difference!!! Not only did they change the way that the car brakes, they look so much better than stock. Couldn't ask for better customer service than Brian!!! One word of advice though....make sure that your offset will clear these calipers!!!

These are a great upgrade for the rear suspension!! Love the adjustability and the look of them much better than stock. Brian always gives excellent customer service and the parts ship out very fast.
