Hi there , does anyone know if you can install gtv 6 rotors to gtv 4 ? Are they an easy swap out
Yes, they are a straight swap.
Common upgrade.
If you want to retain the 4x98 stud pattern you'll need to drill the discs to accomodate the 4 stud hub. You'll also need to either upgrade the calipers to the V6 brembos, or add widening spacers to the original ATE calipers to allow for the vented discs.
Was a common upgrade on group S cars for a while, until it was banned... then allowed again... because common sense prevailed.
No ventilated disks in group s
I'm aware of the rules, thanks.
