Camber front and rear? Is more generally better? I’ve just cut out my turret tops in order to allow the full movement of the baker bm top mounts so max 3deg achievable now
Toe?
Spring rates?
Trying to concentrate on getting it to handle well

What are people running for purely track work in terms of Camber front and rear? Is more generally better? I’ve just cut out my turret tops in order to allow the full movement of the baker bm top mounts so max 3deg achievable now Toe? Spring rates? Trying to concentrate on getting it to handle well |

2 degrees negative camber front.Whatever springs came on my KW V2's, but i feel they're a bit soft personally. Parallel toe front. Extra caster. Standard toe and camber rear. 21mm torsion bars (would prefer slightly stiffer) 30mm arb. It goes alright round tracks, but i'm sure there's a lot of potential there for even more grip. I used to run 3 degrees of negative camber at the front but felt like i was trading off too much straight line grip for mid-corner grip. I agree with Damien though, a lot will be down to your driving style and preference. Don't always take every bit of advice as gospel as others may prefer their setup different to how you like it. ________________________________________ Goldie the track car. |

0 toe makes a big difference I think, when I had mine out last weekend I could really feel the back wanting to rotate. Admittedly last time I drove the car in the dry the rear beam was collapsing so my reference point is pretty low!________________________________________ Rallye Race Car |

-1.5 camber frontStandard rear (xsara vts arms) Toe slight in front, naff all and parallel rear As much castor as I can in the front (less camber as I've a quaife) Mine doesn't run very low, -20mm on the rear, -45mm front with rubber beam mounts as I love the turn in and slide. And pretty soft springs due to road use ________________________________________ Nothing to see here |

Valuable info A lot of my suspension was already there so trying to maximise what’s there - the fronts were originally 5kg so have upgraded the dampers and springs to 7kg which should better match the rear bars I beilieve. I’ll have a play with front camber next time out as cut out the turret tops to give the full range of movement at the weekend so be interesting to feel the difference |

Forgot all about this thought may as well update - I did a day out at combe on the 13th and after setting it to -3deg at the f not to match the rear was concerned about stability but once out was very happy with the way it drove. I thought my 205 handled well but this was better. Still more to go but that’ll come with confidence |
