Great product at a reasonable price

Easy to cut and install... shipped it out fast and I had the product before the week was out. Very easy to cut and install compared to other more expensive products... definitely will use again on our other builds.


This stuff is awesome

Deaden sound of new B&M short throw c6 shifter

Worked like a charm to eliminate shifter vibration and rattling sounds at higher RPM’s. Used remaining product to get rid of hollow sound in trunk. Real difference. Recommend buying more than you think!
