33F/30 R suits the baby r just fine on diablo corsa's.
Trouble is diablo corsa' s no longer cope with 140 bhp,(black lines EVERYWHERE at brands ) and after running the 890 on 209 gpa's they ARE the future!

if you run a higher pressure it takes longer to get them warm and they dont get as warm either.

P x V = constant

T

if my physics serves me well

I'm kind of with Butch on this, 33/30 or 32/30... but 209's are the future, went from a set of 208's after day one at sunny Jerez (ok they were mullered) to a brand new set of 209's and went a good second or two quicker in one session alone.

How quick john?
