Running suspension to low

[TANKSLAPPER]

This is what happens when you go though the fox hole at 150mph+

Even the ride height was , as recommended by KW of 330mm from centre of wheel to top of wheel arch

[glendog74]

Ooops! Not good - I don't even know what ride height my KWs on the car are set to! Should get that checked I suppose! :whistle:

[AlexGTT]

I'll be taking advice on my Intrax ride height as well! What were the dampers set to?

[DazBlackCSL]

Hmmmm

First impressions are bump settings too soft ??
KW settings are a recommendation and base to start with ... what kit is this is ?? and how is the car set up ??

Foxhole at 150mph imposes a load you wont get anywhere else, so it seems a shame to alter the entire set up for one corner.

If you're finally happy with the set up, why not just get rid of the liners, or is that a bit pikey :whistle:

Your comment reminds me of the Foster's ad, were the "sheila" puts a bottle of brandy in the back of the pickup full of cans of Fosters and the wheel fall. LOL

I have now increased the front by 5mm and I will over winter, go on a diet.

It is more noticeable when I take a passenger.

I agree with this. When I first had my KW V3s fitted in 2006 the exact same thing happened to me - but when I brought the car back to the UK to claim for the side airbag that deployed on its own accord, it was rejected because the warranty area manager guy saw the liner wear and claimed the airbag deployment could have been caused by my aftermarket suspension - after all look at the damage its done to the wheelarch liner :bigcry:

I have just changed over to KW club sport's, at the same time put an 1/2 cage in, which stiffen the car up.

You may be right on the bump settings.

KW recommendations are to set halfway for bump and rebound which I started from.

I set the rear to KW's recommendations this was to stiff and couldn't get the power down. I soften the rear by 3 click which I feel is much better now.

I only just soften the front by, only 2 clicks too get a little more grip on turning in. I though a slighly soft front would help this.

I am still play with the set up. I was running 3 degrees front camber & 1.25 rear, when I first put them on. I found under hard braking the ABS would come in and the inside tyres wear was excessive.


I then changed it to 2.25 front 1.25 rear and got understeer and the front outside where get fooked

I'm now back to 2.75 front and 1.75 rear

If you know of any particular settings which you have found to be good on the Ring for a sub 8 min er BTG, then I would grateful to know.

Iain, I think you are just being kind and not mentioning that I was that passenger, and I am touching 15 stone ! I bet that wheel arch is near side aint it mate !:hahaha:, and dont even ask for me to swap you the one i have just bought, you lot have cost me a small fortune lately ! Got yr email about Oct ring trip, will drop you a reply from office tomorrow mate.

[DuncanR]

Alex, im running same suspension on mine, would appreciate any advice you manage to grab hold of,for future reference, as my limited ability and experience precludes me from giving it the beans just yet !

What toe settings are you running? I've never had inside tyre wear problems on the ring due to camber alone.

[TANKSLAPPER]

The toe setting were only slight, around 0.01

But I do think the rear bush on the front wishbone is deflecting changing to toe angle under braking.

I don't know enough about that, but certainly toe out (planned or otherwise) can cause the inner wear problems you're describing. I used to run about 3.5 degrees on the front and didn't have big wear problems.

[AlexGTT]

I agree with Steve there. I run -3 degrees with no inside wear issues.

Duncan, I have just had Intrax fitted 3 weeks ago and have only driven home from Simpson MS, about 20 miles so can't comment at the moment. Hope to do Snetterton in Oct to fiddle about before Ring in November. As far as I know dampers are set to middle to start with.

Speak to Shimmy. He's had Intrax for some time.

[shimmy]

i have Ik2 so only one adjuster on each wheel (dead easy) but i think Duncans car has 4 way. Andrew will know about settings for the ring but i think he did no other tracks as far as i can remember

front camber for me is -2.5 although ideally i need -3.0 for some uk tracks to get the most wear out of the Cups. I tend to go for tyre life span rather than max grip so at places like Bedford i might even run -2.0 to avoid inner tyre wear on those long straights

lately my cups tend to wear pretty evenly but maybe just a fracgtion more on the outside hence my need for slightly more neg camber, although my road tyres (now old) are def wearing more on the inside (hecne why i stayed at -1.5/-2.5 with the adjustable camber plates

looking at my geo i think (if it makes sense) my track toe is 0.5mm out??
