Reply With QuoteChris what tyres/sizes do you run?
My settings are:-
Front 4.5 deg caster, 2.0 deg neg camber and 0.5 deg toe-in.
Rear 1.5 deg neg camber and 0.5 deg toe in.
1.5 degree negative camber on the front probably better for a road car. The rear negative camber may be too much for Group IV rear?
Chris what tyres/sizes do you run?
A more conventional road set up would be-
Front- 0.5 to 1.0 degrees negative camber, 10 minutes toe in (total).
Rear- 0.5 degrees negative camber, 20 minutes toe in (total),
Tyre pressures- 17 to 21psi front, 21 to 24psi rear.

in sorting out n/s camber by adjusting lower transverse arm (has an adjustable inboard rose joint) this has thrown the tracking out.
Two questions.
1. To adjust tracking toe in/out can the steering rack end be turned after loosening the lock nut on the track rod end, or should the track rod end be disconnected and turned in or out? Hawk Herald rack.
2. Adjust castor is the solely by adjusting the bottom leading link (adjustable rose jointed)??
Hi Tim, there should be an outer track rod with an adaptor between it and the steering arm with a locknut on it, slacken this off, vice grips on the steering arm and spanner on the adjuster and screw the steering arm in or out as necessary.
Castor is adjusted on the leading link by lengthening or shortening in. I wound as much on as I could get but you have to watch that this doesn't drag the wheel so far forward in the arch that it fouls on the bodywork. The only caveat really is the inner mount on the lower wishbone, if it's rubber it's going to be under a little more strain and won't last forever. If it's rose jointed then no issues!
Craig has mentioned tyre pressures, i run towards the lower end with 225*50*15 on the front, back end has no camber with 345*35*15s.

I would go with Craig's advice, not mine!
hi Tim
Always set your ground clearance first before setting up your suspension, as it will change the castor settings if done later and keep the front end lower than the rear to keep the under car air pressure negative as it flows from front to the rear of the car

Ground clearance 16cm front 16.9cm rear. Camber -1 front, 0 rear. Working on castor as it was 4 degrees initially. Think I will up this to 5.
Tyre pressures 18psi front 22 rear.
Got to be moving in the right direction there. Pardon the pun....
Maybe a tad more rake on the chassis. Another cm or so. Does that affect your camber too much?
Looking for some fine weather to try it out?
