Camber, Caster & Toe... What should i get it set at?

[LewisTaylor]

Hi all, this is an area i'm pretty thick in tbh. Want to address this at the weekend in my preparation for Nurburgring.

All i need to know is what should i get all these factors set at front and rear for a good track setup. Please note although my car is road legal, it's predominantly a track car so that is all i'm concerned about. I have FK coilovers so camber is fully adjustable on the front

Thanks for any help

I am running -2° camber and about 3" toe out on the front. Handled pretty well on the 'ring.

Thanks mate, -2° sounds like what i should be going for with camber, is that 3 inch's toe out? Been suggested 3mm by someone else and 20 minutes, don't know how they compare lol.

Sounds a lot of toe out to me. We only run 1mm toe out. But everybody's different.

I appreciate your contribution tbh Tony, at the end of the day your racing a Clio and getting good results, think your opinion is gospel here I'm no racing driver and have very little knowledge of setting it up so need to get a good bench mark to start from.

Go see Mark Fish in Harlow.

I think he's on the traders section on here.

I've got a very rich friend with laser wheel alignment gear in his garage.

I need to stop spending silly money where possible, this will be free

It's 3 minutes of toe out not inch/millimetres. Still within the OE spec.

Ah right thank you.

Does anyone know what minutes = in mm?

Depends on the size of the rim, there is a calculator somewhere on the net as I was looking at it last week Sorry can't be of more use with that mate

I ran the 182 trophy & 197 cup parallel.

Sorry, misread post.

On a 15" wheel. 1mm =28 mins. from what I remember.

 

[NorthloopCup]

I run 2.5 degrees camber on the front, as much castor as possible (using Ast top mounts) and about 15-20 minutes of toe out. Handled like a dream at the 'ring last year and has remained unchanged for this very reason.
I also run less toe in on the rear as well. Keeps things nice lively that way. Makes the rear very twitchy but turn in is excellent.

 

[LewisTaylor]

Thanks for all the replies, i think i'm going to go for -2 degree's camber to make the tyres last a bit longer, and about 20 minutes toe out as this seems to be a good compromise too, and know a few people running that setup so can't be too bad

1mm is roughly under 5min, nowhere near 28min(half a degree, you can easily see many mm difference at this angle) !

Agree, its not 28 mins by my calcs. However, nobody has said if it's total toe that is being quoted or single wheel toe.

Easy to calculate and to sum up the figures for 1mm toe are:

1mm toe on a 15" (381mm) wheel = 0.15 degrees (9 mins). So if it was TOTAL toe of 1mm then it would equal 4.5 mins per wheel (as you suggest)
