- my GT came from Germany with that copper combo - well worn

I went to the steel faced S version and used it with an S disc in the street years, but that did not stand up to hard racing so then I went to a KEP stage 3 disc from GPR when i was racing - it worked fine - i again went back to the S disc for street use

these PP's were a lot "stiffer" to push, and back-in-the-day there were some reports of folks tearing out the firewall on 914's using them - I never had a problem, but maybe Dworazik had reinforced that area when the car was built ??

- now available FS since it can't be used on my 3.2

how bad do y'all want one?
