Have any had clutch issues with stg 1 GTI?I can connect you with my friends that are on tuned mk8s. Three gtis, and one R. They rip... no issues... just the clutches that are at risk.
The mk8 GTI now has the mk7 R's clutch, so should be better than the mk7 GTI clutch, which held up well for me, but again, I never gave WOT in 5th or 6th and only WOT in 4th at higher RPMs. If I was passing on a two lane, I'd drop to 3rd and let er rip.
My understanding is the issue with slipping is caused by low RPM, high torque, and the increased resistance from higher gears.
