I ran last autox season with stock conti's add they were pretty miserable and greasy... compared to my previous E36 M3 which had goodyear eagle F1 D3-GS's.
Star Specs on our lemons car seem really grippy thus far and I've enjoyed them in the testing we've done. I'll let you know how they hold up after this weekend and thrashing on them for almost 24 hours
In terms of tire widths and playing around with that... I haven't had time to experiment with that on the Z4.
But you can certainly induce some idiotic power oversteer if all else fails... LOL. Just watch what tires you chose in terms of the rules and class you are running in (e.g. width's, treadwear, etc)
