Suspension

[nrick]

Any takers on the definitive suspension set up for a Tuscan mk1 on Gaz Gold pro's

SP Spacers
235/40 fronts
245/35 rears

Ride height?
Damper settings
Camber
toe in
etc

No bump steer mod yet

Hi Neill,
Ive got the printouts from Bubble and kick motorsport that did mine with Derek in attendance.

Extra castor was added by moving the mount spacers both to the front of the upper ball joint mount.

It handles extremely well now, and turns in sharply.

I can scan the print outs and send them to you if you want.

Cheers

Matt

Grant - re castor, are you running the shims either side of the top ball joint or all in front and have you set bump steer to zero or slight bump out?

I'm converting mine to the later top wishbone set up and interested what set up to start with.

Cheers.

Both top ball joint shims in the front, max castor is good place to start
i now have slight bump out on compression and it
does toe in when i jack the car up, but i don't think the suspension goes there when the car is being driven
when you add the castor, it changes the camber, so you will need to reduce it, bit hard to get your head around
like when you reduce bump steer the track goes toe out
