As per the title really; what spring rates are you running front and rear on your Chim?

I'll talk to you Chris!

450 front
400 rear

A bit hard for the road imho but good on track.

I may reduce these as a compromise.

I used to run standard + 20% which was excellent as standard is too soft.

Thanks. smile

Good to see mine's not as extreme as it might have been. It's running 450lb fronts and 375 (or possibly 350) rears, and, to me, the rear feels about right, but the front a little stiff.

The thing is, I haven't checked the geometry properly yet or played with the damepr settings, so I thought I'd get those sorted and see what other people were running before contemplating a spring change. I'm on the new Gaz Monotubes which I'm told suit stiffer than average spring rates and certainly, overall, they seem to be a much better ride/handling compromise than the standard setup.

I am running the same dampers, they hava about 4 T/D's under their belt and all good.

I think 350 rear and 400 front would be good.

Good, good. What damper settings are you running? I believe mine were supplied with 8 clicks on the front, 6 on the back, so I've got a bit of adjustment to play with still. Currently it's a tad understeery (but that may be due to geometry or even tyre pressures).

Coincidentely I run the same settings for the road and click up about 4 clicks for the track.
That's measured from fully unwound.

I have found that understeer and oversteer vary with tyre choice, damper settings and tyre pressures.
Very difficult to detect and adjust on the road, best book a cheap T/D and spend half a day tweaking.

Yep, to be fair mine's running quite a large difference in tyre size front-to-rear (215f, 245r) which probably doesn't help matters either.

It's actually probably a more or less ideal setup for road use or wet track days. But I stumbled across a couple of deserted roundabouts on the last drive that suggested it might be a bit too front-biased for a track setup in the dry.

I've only got to wait a week and a bit before I get it on track, so will see how it goes. driving

Guadix (as part of the Drive Espana TVR Tour). I think I'd have a hard time getting it through the noise test anwyhere else. It's fully decatted, so even with additional silencers (which I don't have currently) I might struggle to make the usual 98 or 101 dB days over here.

Ditto for me, as recommended by Absolutely Shocks for cruising / fast road. If I get serious about track days apparently 475 front and 400 rear is a good option.

Although I absolutely can't wait for the trip it has compressed all the jobs I wanted to do over the course of the spring into quite a short time, so it's been a manic and rather expensive couple of months since I put my name down. And it's not finished yet. The car is booked into Wheels In Motion for a geo setup on Monday ahead of an early morning departure on Wednesday...
