Well the one that won the race in the GTR video was only an N/A 4AGE which stock makes 120hp at the flywheel. But knowing how Keiichi Tsuchiya builds motors it's most likely has mild cams with ITB's. Which would still only make about 150rwhp if that. Probably has 8kg coilovers 6kg TRD springs, same setup Lovemy86 has, it is the most common setup. Which is one of the stiffest setups, of course next to what I have sitting in my bedroom 10kg coilovers 8kg TRD springs,which is about the stiffest you'll find on any Corolla.
