Not sure if it is in the right section but,

i m seeing some cossie saphs as i want to buy one.

A friend of mine was telling me that rwd models of the saph lack traction on low gears due to the rear wheels loosing geometry under heavy acceleration also he said that this will increase tire wear. I noticed saphs going really low from the back when accelerating but he was saying that the wheels get angled and the tire's surface doesn't all touch the ground and that s why they loose traction and wear tires faster.

Is this true and is there a fix for it? sorry for my bad English

 

Only really applies to lowered cars. You can buy camber shims which sit between hub and arm. Also having adjustable shocks on a harder setting will help reduce angle.Also a 6 degree rear beam the choice is yours.

thanks for your reply, so basically on standard ride height it dosen t affect?

 

It dose affect but more so when lowered.

 

You will still get the same effect due to the standard beam setup, increased negative camber as the rear squats, the more it squats the worse it gets.
The modified beams (6 Degree) minimise this effect, so you get much less camber change.

 

2wd is a better car in my opinion, best to drive and just how a car should be, driven by the rear wheels and steered by the front.
As said if it's not ridiculously lowered you'll be fine, these cars have been around a very long time, tried and tested.

 

It's due to the design of the suspension, but lowering exasperates the camber problem, his right what his saying, as the tyre is not in contact with the surface thus wears the inside edges.

Mine lacks traction big time,wouldn't have it any other way though
