Worked as they should. Quick shipping

The correct one delivered new and in box. Shipped quicker than expected!

Brand new in sealed bag, correct product delivered.

Good deal, comes as described!

Arrived in perfect shape

When first purchasing the kit, it was very straight forward. I told them what I was looking to do, they directed me to the exact kit with everything needed included.
I recently had an issue with one of the struts, and FIP very quickly responded and handled everything with Silvers. New strut arrived at my doorstep within days.
Highly Recommend ordering with FIP.

Delt with this company online. Quick shipping and quick to call about my order to get it solved. 10/10 all around

Set of 3 hood vents installed on my 03 Z06, great product, fits great and pulls out the heat š„µ

Got a great product. In a very timely manner very happy

Great experience, order got messed up and Brian made sure to get it fixed and kept me up to date by texting me.

Exactly what I needed and had it next day

Customer service was great. Order shipped quick. Great value and the change to the car was better than expected. Wife no longer braces herself for the expansion joints and other Ohio road issues.
