Suspension adjustment - bump/rebound

bryce · 15-03-2009, 06:16 PM

I fitted KW V3s to my car round christmas last year, but Ive only just started to use the car properly again.

I set the bump and rebound to KW's reccommended spec, which I found superb to start with, but the more Ive used the car, the more I found it was a bit hard and didnt soak up bumps.

Since then Ive adjusted everything to basically the softest setting on both bump and rebound. The ride is now perfect comfort wise, but the car now doesnt seem as stable - particularly at higher speeds. Ive noticed when over taking and pulling back in, the car seems to float quite a bit. I have a basic understanding of how the susp works, and I believe this is caused by me now running more on the springs, and apposed to the dampers/ shockers.

Is it possible to keep the softness of my current settings, but bring back that planted / stable feel I had before. Or is it a case of compromising one to improve t'other.

Cheers

ps. Ive found this guide quite useful... http://www.koni-na.com/pdfcatalogs/K...ortCatalog.pdf

I'm on Intrax and on the road I put all the settings to max softness and it seems fine. Not helpful I know, but email Thorney perhaps? He knows a fair bit about KWs.

My own view is it's a science and best left to someone who really knows what they're doing.

Agreed! Either that or revert to your previous harder settings and stop being a puff! Or fit a squidgy cushion under your butt...

Colin says you're welcome to give him a call (01234 757633) as the quickest answer for you. He will penn a reply for all to read but it will be about a page long. He's out this evening and we have a corporate event tomorrow, so the earliest for his view here will be tomorrow evening.

Cheers Jo, thats very good of Colin.

Ive sent Thorney an email to see what they'd advise first (bought KWs from them), but if I have no luck I'll give Colin a shout.

Looking forward to Colins write up regardless.

jeez thats soft Nords

standard CSL suspension is about -20F -25R and is better than stock on Intrax i have found

Yep, I'm on -40 back and front? I might try those settings, what ride height?

Nords - you have 50 clicks on the rear if your dampers are the same as mine.

Make sure you have the same spring rates before you start comparing damping clicks
