Tyre wear on track - camber?
A day at Silverstone on new track tyres has confirmed what I'd thought for a while regarding on-track tyre wear.
When pushing it, the outside edges of the inner/central blocks of the front tyres wear fast on tracks with mostly right hand bends, and vice versa for tracks with mostly left hand bends. Wear on the outer and inner edges of the tyres is pretty good, with only a little feathering of the outside edges as expected. Rears wear evenly.
I *think* this means I may need more camber at the front? Although I have AST's (and Powerstation "Type 20" geometry setup, albeit not checked for several years) the top mounts are standard - so I'm guessing I need adjustable top mounts? And, if so, can you get adjustable mounts that are easy to user-set between two different cambers - track vs road for example (since my road tyres don't wear like that)?
Or is it indicative of a fault, or just misalignment?
Opinions welcomed!

ABUSE !
Sorry had to say it !
I'm sure the difference in cornering loads between road and track is the cause, but I honestly don't know the cure.

When the alignment was done it was probably set up for road use. Good grip, without wearing the tyres badly.
The problem with having a track setting is that on a normal road you'll wear the inner edges very quickly, and you might find it'll tramline badly on uneven roads. Although on a track it'll wear evenly and grip bloody well!!!
Adjustable top mounts would be ideal so you could change easily.
(Hope you had fun out on the track)

Not straight forward when at the circuit.
you could get it changed before and after but it will add atleast £100 to the trackday bill
