Ride Height

[simon.b]

When setting up with new shocks, where is the best place to measure ride height to ground so that relative adjustments can be made front to back.

Front lower wishbones have a flattish plated area at the outer end, though this appears to slope slightly front to back.

Rear lower wishbones have various edges and tubes all at different heights.

Cheers,

Simon.

I always use the main chassis rails. They are square ~ so an easy edge to measure against, and do not pivot like the wishbones so give just as accurate a reading. Most people will quote ride heights as the chassis height. As long as you mark the points on the chassis rails so that they are square on it doesnt matter too much where you measure the heights (longtitudinally). Personally I measure between the front wheels and back wheels but to do this I get the car level on ramps (4" is plenty high enough to be able to measure and adjust - just my lengths of timber ramping). If you want to be clever try adjusting with driver weight in the car ~ it makes a little difference ~ you can interpolate between load settings for the compromise that suits you. Dont be afraid to experiment - its quite good fun Keep a note of your settings - it is very easy to lose track of what you are doing...

My first thoughts where to use the chassis rails and If I’d had any sense I would have measured this before I started messing about, but the numbers I’ve been given are for the wishbones.

So is it correct to assume that if the car is set up level to ground the clearance below each rail at both axels will be the same and a generic setup would be 10mm higher at the rear axel with all four wishbones horizontal.

And your right I’ve never touched any of this in the past, but do find it quite interesting and am looking forward to trying a few things out. Good Idea about adjusting on the ramps I have home made pair I think I’ll make two more.

Cheers,

The 'level wishbone' is a good rule of thumb starting point. Set the front this way ~ then measure the chassis rails and equalize (to taste ~ I add a little on the right to allow for me). Go the back and you can go 1/2 to 1 inch higher I reckon (I find quite a large nose down works well but you will find your own preference). It doesnt really matter what the settings are, as long as you record them and the meauring is consistent, you will reiteratively arrive at preferred setings. Much the same as the damper settings, just record, evaluate, adjust. There may always be a different optimum setting ~ every day / road /car / driver is different IMHO.

I agree with Dave, havent got my measurments to hand but think i have about 15mm rake

You should'nt mock....

I've been on a crash diet since I realized I had misinterpreted "corner weighting"
