Best suspension options???

Eh, it depends on which Wilwood kit. Wilwood changed their hubs a couple years back, the track width isn't as wide as they used to make it. But they also increased the diameter of the hub, which is actually the bigger issue now. The hub register on the Wilwoods is significantly larger than any of the factory wheels now, and even larger than a lot of aftermarket wheels.
Do you think I need to go bigger than 11inch rotors for the power (500+) and my usage (cruiser/drag)
