KW Clubsport...good or bad?

[phoenixcsl]

OK my ride heights from floor to w/arch (running 18s)
RR - 623mm
RL - 648mm

sounds a bit wonky to me! :whistle:

Ride height is better measured from centre of wheel :moan:

Is it? Whats the best ride height for coilovered CSL's?

Who knows, certainly not me.:blalalala:


Just hat centre of wheel takes out all selects of tyre/rim size when comparing ride height.

If you set ride height and swap old tyres to knew or 19 to 18 rims, ride height will change of course.

You're no help at all :finga:

Thats a good point on the height measurements.

I need to find a good ride height balance, for some reason the rears were a tad high when I left Simpsons the other week, I'm going to send off the rear shocks to Nitron on the weekend and get them to have a look / rebuild / re-gas the rear shocks.

Ride height depends on what you use car for tbh. The only thing I insist on is front to be 5-10mm higher than rear with driver in, corner weighted as best you can and front clearance big enough so I can still park over speed bumps at Stansted airport short term parking!

That was the problem I have, the car looked level, where I wanted the rears to be a minimum of 5mm lower than the fronts, to be honest the way it has been set up doesn't look too far from standard.

The chaps at Nitron think the rear shocks may be over pressurised as I cant get the drop I want and my rears are not going as low as Alex's from the numbers he's just given.

Can't remember LeonBs Nitron issues, but his car was very difficult to drive on track and he was working with them on it for weeks.

Strange. They've worked well for me.

Not the most accurate way of getting a reading as shim says. Even a variation in tyre pressure would throw it out but by the sounds of it you wanted a rough height to check yours against.

Reason being rears are not matching is due to car being corner weighted. If focusing on this then this obviously involves adjusting the spring perches to get balanced diagonal weight onto each corner, therefore affecting ride height , resulting in it varying.
Overall ride height I requested a drop circa 20mm iirc.

nitrons recommended

having new set set up fitted @ simpsons later this month.
sincerely hope there's none of the above headaches post fit.
20mm lower than standard set up? is that the best height?

If your ride height is varying by that much, corner weighted or not, then something is not right. The ride height itself is just as important as the corner weight and both need to be good but not completely at the expense of the other.

I've witnessed many times corner weights being performed incorrectly, the surface not being properly flat, spring platforms being all over the place etc. When a car is correctly set up for weight, corner weight, spring platforms, ride heights they always come out pretty symetrical.

Aesthetic reasons, practicality or track use its down to preference really and what its to be used for. Is if for mainly track?

Standard is around 600mm +/- 10mm with around 5mm more on the front.

Tbh pooky these were the measurements I made with the car in the driveway having not been moved for some time so not an ideal situation for giving any form of accuracy but a rough guild of height for toby to work from.

Bottom of rim to top of wheel arch is standard form and a better way of measuring ride height but still not 100% accurate. Bodywork could even be out marginally.
When I had my car corner weighted there was a slight variation with rear iirc and you will often see varying slightly, its normal. Sometimes this can even be because the car manufacturers chassis jigs allow a certain amount of tolerance, this means every chassis is slightly different. Combine this with the fact that many cars aren’t balanced to begin with because of fuel tank position, driver and passenger weights etc. and you can sometimes have ride heights different by several millimetres.

In my case as you pointed out Im more than certain this is most probably down to suspension bind where it hasn't been moved for a while and on entry to parking also playing a role.

I'll roll the car and take another measurement this afternoon to give a better and more accurate reading.
