Right, here are the suspension setup details for a Leon Stylance with Sports Suspension - according to Tyres and Exhausts Galore in Leicester (who I found to be very helpful and knowledgeable).
(All measurements are in degrees and minutes)
Front (Left and Right)...
Toe: Min 0° 00’ Max 0° 10’
Camber: Min -1° 11’ Max -0° 11’
Rear (Left and Right)…
Toe: Min -0° 00’ Max 0° 10’
Camber: Min -1° 50’ Max -0° 50’
Front Ride Height (Left and Right)…
Min 363mm
Max 383mm
Rear Ride Height (Left and Right)…
Min 365mm
Max 385mm
The
problem with my car was due to the toe setting at the rear (i.e. the rear wheels were ‘boss eyed’).
If you can imagine an x, y, z axis – where x is the direction in which a car travels forward and backwards (toe), y is perpendicular to the direction of travel (i.e. imagine a fixed axel between the rear wheels) and z is going directly up the side of your wheels (camber) - apologies if this is patronising!! My car had a bad setup in the x axis (toe), so the rear wheels were pulling away from each other, therefore scrubbing the tyres.
Because of the z axis (the camber) they only scrubbed on the inside edge of the wheel.
I had my toe adjusted so that both the back wheels are now pointing in the same direction! When I come to replace my rear tyres, I will adjust the camber to the minimum limits (i.e. – 50 minutes {= -0.8 degrees}), which will stand the wheels as upright as the tolerances suggest I should. This should make the car run on as much of the rear tyre as possible, and not just the inside edge of the tyre.
I hope this makes sense, if not let me know and I’ll try to explain further. Apologies if all of the above is very patronising!
I'm going for a beer now!
Cheers,
Will.
