Tire sizes.. road v slicks ?

[BiggestNizzy]

have you tried checking the tyre temperature across the tyre ? it will let you know what part of the tyre is doing the most work and then you can modify camber/pressure to ensure you are using the whole tyre is being used, then if you find that you prefer to dial in a little more over/under stear you can adjust things to suit ( I will have to get my notes on this as I can't remember the best way to do it.)

Didnt bring the digitemp with me.. should have done but thats just a bit too much anorack for a track day..... Looks like I had the rear pretty close with the front a bit too high..

got my wee suspension book out and it says

if it's oversteering mid corner you could try adding some downforce, (the elise does suffer from a little aerodynamic lift at the rear if memory serves me right) and if you have adjustable suspension you could increase the rear rebound slightly.

Just drop the pressure down to 20/22 when hot and you should be much more planted. Dont get too involved in dampers etc etc when its pretty obvious your tyre pressures are FAR too high.

Now were getting somewhere...

The F1 boys call it "balance" and in a boring race or one where someone is misplaced on the grid and blaming "balance", there's always lots of blethers about it

Easy way to remember is: whichever end you want to grip better, make it softer relative to the other end

...until you are zero PSI at which point I suggest you pump it up again and go make the opposite end harder instead

I think this is why some of the Mk4 Golf Gti boys actually put a REAR anti-roll bar on to make the car turn in a little better...because the stiffening of the back end shifts the effective balance and the front appears grippier (actually because the back is less grippier). And I think this is also why Robin discouraged me from fitting a stiffer front ARB to the Golf in search of less understeer. In the end I did nothing as I have become more distracted by the screaming sproglets in the back seats anyway

Know all about setting up suspension... it was the recomendation I read on the tyre pressure that threw me.

It may surprise you to know that I do honestly own a full set of digital corner weight scales, full geo kit, motor dyno, tire warmers, and a laptop programable ECU speed control unit... damper dyno and 20+ sets of springs... over 40 sets of slicks and various wet/intermediate tires. Maybe 12 or so race spec engines....

If you cant get the tires working right then everything else is useless.

Now must remember the digitherm for the next one...

Ah, but funny things happen at 10th scale Seriously, there are things you'd do for setup on an RC car that would kill you in a real one - some changes seem to do the exact opposite in 1th scale...

[quote="Victor MeldrewI have been trying to get the hot pressure to be around 28f 30r after reading an article about them written by a Toyo technical advice bloke talking specificaly about using the 888's on an Elise. that was the pressures the manufacturer recomended.[/quote]

Yup way too high - drop that by about 10 and you should find a big difference. Think that article from Jon suggested 17F and 22R, but I'd go for 20R to start with and see how the car feels.

I have found though that running the tyres on road at these pressures can increase tyre wear markedly.

I've just got brand new 888's on my S1 so will let you know how i find them
