Anybody have good settings for the Supra RZ Stage 3 turbo around 650 HP that can actually handle? All the setups on GTvault are for 1000+HP and suck at handling.
Try this - it's not great as there does indeed seem to be a major inbalance in the Supra's chassis that shows up badly when you throw horse power at it.
It's about as good as I can get it and it'll do mid 1:10's at Midfield (634 HP):
