front/rear ride height

[Tom86]

To improve handling. Ideally how should a car sit when you adjusting ride heights? What I mean by this is should the front and rear be at the same height or should the front sit lower than rear and so on.

The handbook I got with my coilover recommend that front and rear height should be exactly the same something like 175mm from ground to top of wheel arch. But looking at a few car in a car park from factory they seem to have the front slightly lower than the rear anyone know what is the reason for this? is it just the weight of the engine pushing the front lower?

Good luck with having the top of the wheel arch 175mm from the ground

There s no simple answer to this other than having the frotn a little lower should help a bit with aero.

It all depends on centre of gravity, roll centre and roll centre migration etc. For best handling there is no simple rule for all cars.

Hahaha I don't where I got 175mm from what I meant to say was 578mm.

I'd go for: Lower at the back for rear wheel drive Celica's and your AE86.

It is a quick way to move some of the weight balance to the back over the rear wheels for better corner exit.

Also helps to keep the front diving/rear rising under brakes.

It only needs to be 25mm up more at the front.

A good starting height is to have the front lower control arms and the rear lower trailing arms parallel to the road, that typically puts the panhard rod parallel through the centreline of the diff.

Then raise the front up.
