Had a chance to run a brand new set of Conti slicks earlier this year at Sebring. Amazing grip, pulled nearly 1.8 G's in the hairpin during their first and only session when the passenger side valvetrain came apart and took the built motor with it. Needless to say this set is for sale in the classified mounted on a brand new set of Wedsports 105N's. Whole package not a whole lot more than a new set of R7's.

That guy is right! Never buy used slicks. In 2009, I ran a set of used Hoosiers for the full AutoX season and I ended up finishing 2nd in Mod. Unless you want those kind of results, don't buy used.

Wait... maybe you can buy used.

+1 for JB. I used to buy from them when I ran my old car. They don’t always have the sizes we are looking for though...

They’ll be fine for both, but will be pretty far off any dedicated autocross tires because they are designed to work best hot as they’re an endurance tire. So if you can hot lap they’ll get better each run, but these are slower than R7’s and A7’s.

I have run the Conti slicks from Bimmerworld for testing day purposes. They are a bit slower than R7s at their best but get greasy a lot faster. However, for the price they make a lot of sense and I could always get at least 3 track days out of a used set. They are a great DE tire, but I think they are too slow coming up to temp to be a good autocross tire (speaking without experience).

That said, if you have only done four track days, I wouldn't move from stock tires to slicks. Grippy tires mask driving errors and will impede your development. I would stick with lower grip tires until you really feel like the tires and not your driving are the limiting factor.

Conti slicks are basically built as an endurance tire. They have an extra layer of tread. Most of the races they are used for are 2-6 hours. They would be tough to get heat into fast enough for autocross purposes.
