S1 Camber ??

Thought it was time to sort out the Elise's Handling. What do the rest of you set your Camber at ?

The car understeers then you get plenty of oversteer, knife edge stuff. I was thinking it might be down to me but Ali took the car around Knockhill and agreed with me (infact, he looked a little rattled).

It's Set-Up
110/120 ride height
0.5 - 2.0 Camber
0(ish) - 2mm Toe

Going to get it set-up next week, any thoughts on a more Track Oriented set-up ?

Cheers

Alan

I would give it a bit more front neg camber, -2.0, touch more rear -2.5 and if the handling is that twitchy then need to check the rear bump steer. Most likely your toe links are giving the rears either not enough or to much toe on bump. Not easy to check but Clarkes should be able to do it.

Edit: also need to have a look at your front castor shims and see that they are equal each side. More shims to the front of the car makes the steering more weighty IIRC. More to the rear of the car makes it slower to self centre IYSWIM.

Get the read out form the hunter to see what your base settings really are, it should be fairly obvious once you see them. Alternatively if you can convince Mark Hutchison to come out of retirement and geo it for you then you will have a sweet handling car.

Very much depends whether you want it set up for track use or road use or somewhere in between.

For a fast road/track compromise I would be looking to run the following:

Front
Toe: 1.5mm Toe Out each side
Camber: -1.5 Degrees each side

Rear
Toe: 2mm Toe In each side
Camber: -2.5 Degrees each side

:thumbsup

Scotty's old 340R, after Mark had set it up, is the best handling Elise derivative I have ever driven.

Must get mine in for a check. It has had all the suspension components off for refurb, new Hoffman's Nitrons, and all ball joints, wishbone bushes, track rod ends etc, replaced

As far as I understand camber should still be the same, no shims moved, but toe could be out.

I believe Mark will still set-up your car but charges £100 - £120.

I would love to get the car corner weighted as well.

I will probably take it to Clarkes and get it set-up and add more camber, Take it down to the next KH day and adjust from there. Thanks for the input :thumbsup

I think your rear toe will be the issue if you think it's snapping on the throttle. Exactly what mine did when I fouled mine up on fitting uprated toe links.

Me and Mr Crozier set the car using the poles and string method, i set the toe to 2mm in each side. Be interesting to see how accurate we got it.

I think my front toe was too conservative Dan when it was last set up. Rest of the figures were as yours, but toe was only around 0.5mm, so will take it upto 1.5mm.

I think so Tut,

Main reason is to get the car set-up properly, so its ready to sell. I'm getting on great with driving. Everyone is giving me a hard time about it, but I know what I can and can't do.

I'm up for the all day one

Hands fecked Dan, lost the use of my rist and fingers (upwards motion). Specailist sat me down last week and told me it won't come back, looking at further operations next year. I will do my best to prove him wrong.

Putting my efforts into a new house, can't drive the Elise on track (i will have a go though) so might as well use the money for a deposit.

Would be good to get it checked but KH in 'absolutely torrential' rain was probably not the best conditions to make any definitive judgements on the setup. I felt it had very little grip overall compared to mine on new 888s. I didn't think it understeered much at all but very was prone to lift off and power oversteer (Ape would love it!). Maybe worth looking at the tryres (inc pressures) and damper settings.

btw the conditions were so bad I was feathering and correcting ALL the way along railway straight. Half turn of opposite lock cresting the rise on the pit straight anyone? (changed up to 5th before the crest after that).
