Keeping 300Kw On The Ground

[GTSBoy]

But what ARBs did you have in it?

What dampers? Did you have them dyno'd/valved?

A taller diff ratio will help

As with bump steer as mentioned what about what the camber is doing as the arse end squats, may need to look at roll center adjustments and or offset bushs and adjustable lenght arms if its gaining to much camber

You can also go to soft with spring and shock rates, you don't want it squating so fast that it bounces off the bump stops, this is a problem I'm nutting out in my 34

The diff is a helical from an S15 with a 4.3 ratio, hook up from this is good. Always predictable, pulls the nose in rather pushes the arse out.

There's your problem, get a REAL mechanical differential.

Helical diffs are good in sense they make both wheels turn, however will never distribute torque evenly across both sides - thus causing your tail end to go all over the shop.

Put a 1/1.5/2 way in the rear.

I make probably 330+kW and I can happily put my foot down in 2nd without ridiculous wheel spin.
