dont need to be a guinea pig when JRZ RS dampers are known to be so amazing. They are one of the most popular dampers used in record setting time attack cars. Its the reason why many Porsche GT3s and S2k owners consider the JRZ RS one of the best dampers you can buy. There are of course better dampers but you are paying over 15k, versus 6k for JRZ dampers that are way beyond KW has to offer on a consumer level. Just because on M3 applications does not mean its a whole new setup. With the correct guidance, it would not be a problem. JRZ dampers on a Porsche GT3 are no much different in performance capabilities than JRZ dampers on M3 or S2k.
I think JRZ RS are about as good as it gets without blowing 15-20k on full race dampers.
