Wheel Alignments

[Proximity Motorsport]

Well probably the most least looked at thing on alot of peoples cars are the wheels alignment. A good wheel alignment can completely change the feel of your car and make it handle twice as good. Just wondering if anyone here who seriously does suspension work and knows a bit about wheel alignments if you could please post a copy of your spec sheet or even just post it. Mainly for people with r32s

A wheel alignment (especially camber) will depend on the amount of antiroll (low speed bump, swaybars, spring rates and roll couple), tyres being run etc. It's hard to suggest an alignment without knowing the full details of the setup.

Well my car has adjustable rose joint rear lower control arms, adjustable rosejoint cusco camber arms, adjustable rosejoint traction rods and hicas lock bar, Tein HA coilovers and adjustable sway bars front and rear. Soon to be cusco castor rods, still dont know what kind of upper camber for front to get.. was thinking cusco but i cant find any for gtst only gtr. Also be getting new tie rods... also do not know what brand yet.

also has a mini spool diff

Sorry, I meant what size swaybars, what spring rates, what tyres used (R-comp or road tyres) and application (circuit, road, drift, etc).

[Proximity Motorsport]

i got 8kg front and 6kg rear springs... i run coilovers on around 6-8 clicks out of 16 for damper.

Sway bars i cant remember sizes but its fattest front whiteline has and second fattest rear, both adjustable.

Tyres are 235/40/r18 rear and 215/35/r18 front

Application is street and some drift

Anyhelp would be really good cause my local tyre shops have no idea about how to align a cars wheels for handling etc... only for keeping my car in a straight line when i let go of steering wheel

Try this

Front:

Camber: -2deg

Castor: 8deg

Toe: 2mm out total

If you do a fair bit of street driving, go with less toe out as it will kill the inside of your tyres, something like 1mm or even 0 toe.

Rear:

Camber: -0.5deg

Toe: 2mm in total

what advantage will toe give me... for rear i was thinking neatral toe and 0.25 neg camber.. What does toe out/in do?

thanks

Toe is how far the wheel is tilted on the front, toe in on both sides of the car causes the wheels to push towards center, this gives a straighter line as the car moves around less. toe out is the opposite, it makes the wheels pull off center but also tends to make it easier to turn on the fronts as the inner wheel will pull more then the outer and can help reduce understeer if done right.

well...basically toe out makes the car unstable, and toe inmakes it stable. Toe in also reduces the wear on tyres from excessive camber because it drags more of the tyre across the road. When you get a road style wheel alignment, the more camber you have, the more toe in they run.

But, for track use it is critical.

Front to out improves turn in to corners - the inside tyre is pointing where you are about to steer to help you out. Too much toe out at the front results in understeer though.

Rear toe out causes the rear to be "unstable" in corners. For drifting I think people like this, it encourages the tail to get out initially, but might make it harder to control once it is out. For racing most people don't like toe out, you end up sliding into corners. Personally I don't mind some steering from the rear on some tracks (like wakefield) but I think that is very much up to your driving style.

Anyway, enough dribbling....I run 0-1mm toe out at the back and 1-2mm toe out at the front for track use.
