What ride height should I be looking to achieve!
Discussion
After reading several threads I reckon that the ride height needs adjusting on my 4.2 cerb, it is definately lower at the rear than at the front!
It is running with AVO's all round dont know what spring strength I have (dont think they are excessively hard)
Anyone got any reccomendations as to the best height and measurered from where, should I set level front & rear, higher at the rear or what?

It should definitely be higher at the rear than the front. I;m sure its something like a 25mm rake - ie rear is higher than the front. If its higher at the front air gets under the body at speed and can lift it, also under acceleration, the rear obviously squats down, so it needs to be higher to compensate for this.
The actual figure for the correct height I'm not sure of. But what you need to aim for is to adjust the shocks - I'm assuming you have adjustable height shocks - to get the lower wishbone arms of each suspension corner as near as possible to parallel to the ground.
Remember the Cerb is a serious performance supercar, not a Max Power Corsa that looks cool cos its low! The suspension needs to be set for handling, not looks.
PS I've just gone out and measured mine. Mine was set up by Steve Howard at Euphoria, on Gaz Gold adjustables. I measured the height from each end of the chassis tube (the one that runs under the car doors) to the ground.
Front = 134mm
Rear = 146mm

I Funnily enough this was something I was asking about the other day, but I didn't get any replies. 
I have been out playing and currently have the car set at 120mm front and 185mm rear (measurements taken from the furthest extreams of the chassis), the car feels good, how good remains to be seen at the weekend on track. I'm looking at a suck it and see type of development.

Looks like I need to go out and have some more tweaking later today, given other people's figures/suggestions.
I was taking the datum points as being the inner rails rather the that outer tubes,but I guess that makes little to no difference.
My car felt 'light' in the rear, on the motorway the other day, with my wife and child in the car, and a couple of folding chairs in teh boot. Hense the need to tweek the suspension, I've also hardened up the rear shocks, so guess that's helped too.
