ive asked this before but cant find the old post.

i have a bmw m5 and am looking to replace the tyres.

at the mo it has continentals on the front and one conti and one fulda on the rear.

im thinking this isnt the best for any up and coming track days
im fucked if im buying a spare set of wheels and tyres just for track days so i need a some road tyres that will perform well on track.

rears are 275/35x18! fronts are slighty thinner.
