I am one of the few people in the world that own a set of the MEM-TEK modified ZR4's.
MEM-TEK was kind enough to come down today and make some modifications to the ZR4's on the Vette. In a quick testing after the mod's the front was JTG against the PL3 and TruSpeed. The Truspeed was able to get PT's on the rear out to about 300' when the outside taillight was targeted and JFG on center mass targeting.
It's an incredible change in performance. I feel 100% certain the ZR4's will protect me should the need arise.
MEM-TEK a special thank you for making the trip down and for spending the enormous about of time I certain it took to come up with these modifications. I am looking forward to our next Jammerfest so we will have documented results on how well these perform.
