Camber, Castor, Toe etc

Postby BigDon » Sun Jun 19, 2005 6:45 pm

I am just about ready to put my new suspension in my car and was wondering if any one could suggest some specs/ settings for the wheel alignment for my AE101 FXGT non super strut.

It is for track day and aggressive road use and I’m not particularly concerned with tyre wear as long as it goes around corners as well as it can.

Below is the suspension that I have and am putting in, if that makes a difference to how it would be set up.

TRD front sway bar 28mm, 57% higher spring rate
TRD front sway bar 19.1mm, 27% higher spring rate
TRD coilovers with 78.4NM front springs and 58.8NM rear springs
TRD 3 way front brace
All new TRD bushes, except for lower arm bush NO 2 which TRD no longer make.

Also I am after an after market rear strut brace and replacement Urethane lower arm bush NO 2. Does any one knows of where you can get them or get something that can be modified to fit?

As for the camber adjustment, Mr Revhead mentioned the use of eccentric bolts to adjust camber in another post, are these bolts used where the hub bolts to the Strut? Alternatively, I would prefer adjustable top camber plates but the TRD coilovers don’t have then and TRD don’t make them separately for the FX, so does anyone know of any that could be fitted (if they are needed).

Thanks for your help.

Any off the shelf camber plate tein,racepro etc can be made to fit, just a matter of machining up spacers to go under & on top of the bearing to adapt them to your coilovers.

As for alignment specs, I've found generally it'll depend on driver preference for a road car what you use but around -1degree of camber, +2-3degree of caster if you can get it, which you should be able to with camber plates. Toe in/out I'd run basically straight ahead at the front & probably a lil bit of toe out on the rear say 0.5mm a side. Can't remember exactly what I'm running on my road car but it'd be close to those, any more camber & I found you start chewing out tyres.

yeah the more negative camber that u get is then the more heavier the steering will become , but as for your setting , like wot was said above its wot u use it for , i set my race car at -3.00 degrees at the rear and depending on wot trak that ur racing on depends on the front , for pukekohe i run -3.00 / -3.50 degrees on the left and -2.50 dgrees on the right as pukekohe is a right turning biased trak .

hmmm id be seeing if i could get more stiffness in the rear... with a front wheel drive you want the rear to be quite stiff to help turn in.
now theres a lot les weight in the rear so you may be ok, but just have a think about that

Thanks for the replies guys.

Mr Revhead, what spring stiffness would you suggest for the rears, the ones I have are the TRD ones that came with the coilovers, so assumed they would right for the car.
