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

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 ??

[El_Gordo]

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??

[DuncanR]

Thx Alex, Shimmy, methinks that i will bring the big blue folder Andrew gave me up to the bedroom ! It will raise the height of the TV at least so i can see the subtitles on the naughty German movies! There were some settings in there I recall which were Ring specific. I would also be doing some Bedford track days as its on my doorstep so advice on the changes required/advised would be appreciated, unless someone has come up with a CLS/TRACK/SETTINGS folder on here:drool:.
With the wealth of knowledge you guys have, maybe 10 of you could arrive at a reasonable starting benchmark for some of the popular tracks, thats my lazy side coming in !!:hahaha: All monies I save will be spent over the bar in Blaue Ecke...well...some of it anyway.

[glendog74]

I'm the same as Shimmy - running neg 2.5 degrees on track this yearbut have found it to be just not enough as my Cup tyre have worn on the outsides prematurely...

Will run neg 3.0 degrees now.

i have loads of setting for different tracks based on Dontdobends blue folder and my experiences this year but not sure how it relates to 4 way Intrax tbh

I have been to Bedford more times than i care to remember. Biggest issue there is that it kills brakes and tyres very easily so take it easy on number of laps especially when air temp warm.

Intrax Ik2 clicks from hardest setting as follows if it helps.

Road - F20, R25
Bedford F10 R12
Silverstone, Snett - F9, R13
Donny - F11, R14

Just as a comparison Dontdobends had the Ring down as F18, R22 9nearly road settings)

I agree with Short Stuff on this one. I defo need to run -3.0 fro the same reasons :thumbs:

[DuncanR]

Shimmy, your memory serves well, they are indeed 4 ways on my car, is that good ? lol

[shimmy]

Well good if you like tinkering and driving that little bit nearer the limit AND BAD if you have a poor memory as you will spend all trckdays returning each dial to ZERO coz you cant remeber what your setting is!

overall :thumbs: but buy a pen!

[DuncanR]

Shimmy, im 52 mate ! and have spent most of those years living near the edge ! Including skydiving where speeds reached were up to 200mph, and before the Scientists amongst you question that,it is possible in a head down position NOT a stable spread one ! I will be more than happy to leave the car as Andrew had it, as I neither have at the moment, nor do I anticipate achieving very quickly either the balls,knowledge or talent to start tinkering with something, which is then going to cost you €22 a lap to check out ! I have a mindset at the moment to enjoy the Ring, and the company ..not endure it ! wont you lot take the p**s now if you see I have stuffed it somewhere :bigcry:

[_Nathan_]

You'd be better off learning about suspension adjustment with simpler dampers as with the separate bump, slow and fast rebound you have much more scope for ruining the handling, but set up well the dampers you have are the bollocks.

I'd only move to 4 ways now as I will have an engineer with me at the track that can translate my feedback on the handling in to adjustments, left to my own devices I'd end up with a clown car :D

[TANKSLAPPER]

Duncan, Nathan who posts on here is not Nathancsl the green one.

If I was you, I would consider swapping your 4 way intraxs for nathan 2 way intraxs plus a little bit of silver.

This way you could manage the set up easier. NathanCSL has 2 way on his green one

i agree, Andrew will have the 4 way dialed in for the ring, and that might do you for the road as well BUT on track you might want to firm it up a little event though you are 52 qand your bones may be a bit brittle!:beer:

[glendog74]

:hahaha: :hahaha: :hahaha:

[DuncanR]

Iain, thx for heads up about the various Nathans ! As to letting him have my 4 ways, i need all the help i can get mate !! :hahaha:, sounds like a good idea, but by the time we have swapped everything over etc., the silver would probably be eroded and I would be kicking myself later if everyone keeps saying "yeahh...2 ways are fine.... but 4 ways would be better "... I would like to think that when comes the time for selling it, having the 4 ways fitted would be a plus.
Ref the Oct Ring trip, i hadnt realised the trips I have already planned, im shooting in Scotland the week leading up to that week-end,then leaving early as I had forgotten that Im going to watch Saints in the Heineken Cup in Perpignan which is the Friday night, flying back to Luton on Saturday afternoon landing 13:15, I could jump straight into the motor and drive straight out there, 400 mile trip for me, so about 8 hours with ferry etc. and breaks. Just about make the pub for last orders !

[DuncanR]

Shimmy, im new to all this mate, please forward me the Intrax 4 way CSL settings for Bedford with the OAP addendum !
