Got the Tuscan back and its much better. It will cruise happily at 100 mph with 1 finger on the wheel, without trying to dark across the road over every bump.
Strange this is that they couldnt dial in enough positive camber on the front, it was maxed out aparently at about 1.4-1.5 degrees negative, I was hoping for 1 degree.
Does anyone know the ideal ride height for these?

The bump steer on my Mk1 Tuscan was lethal when I originally bought it and the fact it took your full concentration to hold it in a straight line at 50 mph made it a full on widow maker. (front tracking was causing the driving in a straight line issue - it actually had toe out FFS)
I replaced the ball joints, lower wishbones, upper wishbones, poly bushes, installed AST shocks, front wheel spacers and raised the ride height. This improved it a considerable amount - pot holes no longer cause a change in direction. In my opinion increasing the ride height made the biggest difference and the only reason I raised it is because I could not get over the speed humps where I live - but for example on a motorway where you occasionally get a cambered undulation in the surface I literally might as well be sitting in the passenger seat as it swerves a considerable amount. It still tends to track ruts in the road quite badly as well.
I'll be honest I could never get this car anywhere near its stated top speed even with all the modifications because I have not found a road surface flat enough! I love this car and in 9 months of owning it I have fired the best part of £11k (in parts) into it on top of buying it - but it does not feel part of me when driving it hard - I previously owned a 1983 Alfa Romeo GTV6 that was stripped out with a cage, 3l engine and an LSD - The car would dance to what ever tune you wanted to play - it made you feel invincible when driving because of the confidence it inspired.
With the Tuscan the problem is not managing the power it is the dynamics of the chassis . What I mean by this is - hold a constant speed say 120mph to take the power out of the equation and the effort required to keep the car where you want it is massive. If anyone owns a Tuscan that can cruise at 120 without requiring the same concentration level to gain membership to MENSA please tell me what setup you are running.
Agree with you here. Did you find any solution?I replaced the ball joints, lower wishbones, upper wishbones, poly bushes, installed AST shocks, front wheel spacers and raised the ride height.

I sound like a broken record on this subject but get the rack height set properly, ie measure the bump steer. It made a massive difference to my Tuscan and it's now happy at crazy speeds on bumpy B roads, never mind motorways, and the scary behaviour under braking is minimised as well.

Second this, Tuscan MK1, raised rack by 10mm and full Geo. perfect at up to 140 much more manageable.Basil Brush said:

Mine is a 51 plate (Jan 02) so would it be 'safe' for me to assume a 10mm spacer would help or do I need to measure the bump steer as per MPETT's post in this post?I was going to post a link to this thread but then it might look like I'm stalking you! I've still done nothing to mine (time and facilities or paying someone else are the reasons) but I might bet opportunity to look more into it early next year. I have the 'Silverstone' spacers on my wheels, but that's it currently.
