The rears GC springs I had on are GC200.64.58 (8/2.5"/340 lbs)were the ground control springs realy that much more stiffer than the Shine? I have shine, and I think they are fine, nothing too harsh. the GC must have been bone jarring!
I understand that the Shine VR6s are 250 lbs/" the front were stiffer but I cannot read the numbers on them and yest they were very stiff
I do not think the Shine are too harsh but stiffer than stock.. I can rally feel the difference with my Jetta which has the OEM
