i have 2001 P38 Vogue, which has developed wanderlust, it picks up on every white line, and bump in the road and decides to go wherever it likes. steering damper has been changed front tyres are new and all ball joints etc are fine with no free play, but still it has a mind of its own!!!!!!!!!!!!!!!!!! my wife refused to drive it as she wants to stay on the road. ANY IDEAS thanks

WHat size are the weels? 18" with 255/65/r18's with pirelli scorpions are the best choice.

P38s are prone to "tramlining" if you use any wheel size above 18" and any tyres other than Pirelli Scorpions......it improves a million percent if you use 18" Scorpions, although there are those with 22" bling bling wheels with spinners who argue their wheels are fantastic......

Avoid cheap tyres or even other good makes, and go for nothing other than the Scorpions - you are more or less guaranteed to improve the wafting about the road right away.

Nothing wrong with Wranglers, just that P38s sometimes don't like anything other than Pirelli Scorpions.

thanks for replies, wheels are standard 18" with new Pirelli Scorpion outer edges do seem a little worn already but tracking is spot on as far as can tell suspesnion height is correct and a full laser geometery check showed nothing wrong but still it wanders

This info may help?

Curtosy of irishrover.
standard height 100mm from bump stops
Front Rear
Extended 120-180 105-150
Standard 95-150 85-130
Low 75-140 75-120
Access 50-110 50-100

calibration blocks are primarily designed for use with Test Book and are too time consuming
with Rovacom or other software which enables changes to be made "On the fly".
Here are the values from the wheel arch to the wheel CENTRE with front tyre pressure 28psi and rears 38psi,
car must be on firm level ground.
STANDARD height 470mm +/- 7mm
HIGH profile 510mm +/- 7mm
ACCESS height 405mm +/- 7mm
**LOW profile (Motorway) height is calculated by EAS ECU and cannot be modified.
