pulling right under acceleration
I assume this is due to not yet having a proper geo setup (this is very high on the list of things to do, obviously). I've done ride height and
front toe & camber but not done the rear other than "roughly parallel by eye".
Currently it drives well, but under acceleration when the rears are spinning, it pulls hard to the left (back swings out to the right).
What should I be looking at to address this? Rear toe (I assume a bit of toe in is what I'm looking for)? Could it just be the way the LSD
distributes power between the wheels?

Dont spin the wheels. It's going to go all over the place if there's no grip on the rear wheels

Quite.. You will find the nearest lamp post.. You should get the geometry set up though, string box for me seems to have worked o.k not sure but there
must be a few threads on here on a DIY setup?

What are your tire pressures?

True. It is fun though. (I was careful to do it in a wide, empty bit of road). Most of the time I'll have traction control to help deal with
this sort of thing, I just had it turned off for giggles.
I'll get the geo set up and see how it goes.

Isn't this something to do with the rotation of the propshaft/engine under hard acceleration, where giving it the boot twists the chassis and
(I'm guessing) would cause uneven traction?

Probably due to more weight on RH back wheel under acceleration, giving that wheel more bite/less slip.
But, if your setup is anything like some of the big name cars I've seen, the wheels could be pointing anywhere.
Cheers,
Nev.

On an IRS car you need to get the toe-in and alignment of the rear set properly (a rear wheel should never toe-out) and the corner weights set
with the car loaded as it normally driven.
