I found that I didn't need to alter my setup for a standard Celica SSII despite there being nearly 100bhp difference in power.
The LSD helps a little with the tyre wear. Won the Amateur Japanese championship using this setup. Made for some very close races, especially with the AI Supra.
Tried this, rather than my usual Mitsubishi FTO, in the Professional FF series. Used T2 superhards and a no pit strategy. Worked nicely, except for the Trial Mountain reverse, where I came up against a Spoon Civic. Git beat me by about a second even tho' he'd pited.
