ZTT tracking

Reaper · 15th November 2009, 17:25

My fathers 04 plate ZTT drifts off to the left, he's had it tracked by different places and even changed to a differnt brand of tyres to try and combat this. Is there anything that you all know about that needs to be changed?

His ZTT hasnt been in an acciedent.

Hi
what size tyres are you using 40 or 45 the low profile on the ztt tends to catch groves in the road but if you have changed the tyres then i would check the suspension for wear and the steering for damage apart from that i would check the toe-in and toe-out of the tyres

This has come up before and on many instances it is the camber of roads that make it drift inward.
Not sure of any other things myself without starting changing Steering/Suspension items.

Thanks guys. Cymrudragan all 4 wheels realigned. Wish it was just that. John I might do just that. 'T-cut' thanks for the link, I had no idea there was a phonmomenon. But, it certainly puts the the delemma I am having in perspective. Well sort of... I have noticed uneven tyre wear along with the drift, although my Rover tends to pull left rather then drift. It is quite dangerous, as I only need to take my eyes off the road for a second and she is already crossing lanes. I really don't like it and haven't given up yet solving this problem. Anyone have any advise on wishbone joints and how to assess them?

Copied from the other thread on this:

The left drift problem is very commonly reported, even after a full laser reset. The general concensus is it's a road camber/car weight thing. This tends to support my observation that the car drifts right when driven on the right side of the road. However, a pull left is something else. It could be due to several factors like tracking errors, suspension problems, binding brakes or tyre issues. Any good tracking station should be able to identify a pull to the side, whereas the drift usually leaves them perplexed.

Very few of these cars can be allowed to run more than 50 yards hands off.
