rear wheel camber

[marT350T]

What camber do you set your rear wheels to on a RWD car ?

I am not expert mate but for drag racing I'd say 0

Camber is for cornering to keep the tyre in contact with the track, and we don't corner so keep it at 0

Fronts are different but it depends on what the car is

Thanks for the reply.

I was thinking of trying a couple of degrees positive so when the car squats down this would alter to approx 0.

What do you think ?

suspension movement in an IRS set up is parallel isn't it ? so in my view camber wouldn't change dependant on squat so there would be no need to counteract it. If you're seeing uneven tyre wear, check the tyre pressures and rear toe.

For drag racing, you want the maximum tyre contact patch so zero camber and zero toe would acheive this.

Suspension movement on an IRS isn't parallel. It works in two arcs, imagine very large bracket marks and you'll get the idea. Best not to have an IRS in drag racing, of course, but limiting its movement is a help. Jon Webster has worked on this quite a lot, on Nissan Skyline rear ends, so perhaps best to give him a call for an easy solution.
