In relation to the engines, you will never know exactly what HP they have, thats something that is very well guarded. Have you seen the way the mech's all crowd around when the bonnet is open? If your talking brake discs with the other bit, I doubt it, V8 Supercars all run 17" rims, making it impossible to run brakes that big. Blue_stivo, I know exactly what your saying about small fry in relation to the actual cost, but your never going to convince me that they arent putting as much effort as is necessary into being a top team in V8 supercar, they wouldn't be there otherwise. Im leaning toward the TRD/Prodrive F1 involvement more than anything else. I think your spot on with that. Anyway, we are off topic, good to see that TRD is going to be backed by a company that knows what its doing in the performance dept. Bring on the turbocharged Toyotas. . . . My godfather used to tune a some of the other ones. I know that back when the Xerox sponsored car (a wayward back of the pack guy haha) my godfather was tuning it. Those results though were out of V8 supercar magazine believe it or not. They enlightened on the differences between the two camps and that's what they were. 15in discs for the ford and 16in for the holden then I guess? I had the weird impression they were running 18in now. I dunno why :S. I know that they were the main differences though. Not much huh. Oopsies, we kinda hijacked this thread JC (most of it my fault) haha. Back on track. This could be good. The TRD Aurion is sounding mighty fine. The new corolla chassis is so ugly though. Makes me think what Prodrive will do when developing a TRD corolla, and what powerplant to use (super 2000 inspired I guess)
