After going back and forth a hundred times on wheels and tires I've settled on RE-11's for a street/autox/track triple duty tire, wet and dry. 305/30/19 on 19x11 rear and 275/35/18 on 18x9.5 fronts (maybe 265 in front to better visually match the rear, but 275 gives more tread).

Any idea how much slower they are than something like the Rivals or new RS3's or ZII's in either autox or track scenarios?

This is going on a C5Z06 with the Pfadt JOC shocks and sway bars, stock leaf springs, delrin bushings, and a mild-ish alignment with probably -1.5 to 2 degrees camber.

I went with the 265 up front.
I haven't tracked them yet but on the street they are noticeably sticker than the NT05 I did track a couple of times. Also better in the rain.
I don't know about the other tires mentioned but you want be disappointed.

RE-11 are very good, not quite slicks. but they work very well.
I used them quite a bit till I went up to 285 35 18 & 325 30 19.
they are not available so I went with Michelin Pilot SS.
I do like the Michelin better Track or street and they last longer too.
Talk to Scott at Bastians tell him I sent you

I tossed a coin between RE-11 and Michelin PSS, figuring the RE-11 would be better on track and the PSS better on street. Looks like I might end up switching to PSS after the RE-11's are toast.

Also just realized for RE-11 the 265/35/18 has been updated to "200" utqg while the 275/35/18 size has not, so I have to buy the 265's if I want to compete in most street tire competitions.

I have personal experience with the following NT05, AD08, RS3, Z2 and currently on the new RE11A.

Note... they are/were all on my FF cars (Cobalt SSTC 320WHP and a 2005 Lancer RA setup for autocross) and not the Corvette.

My favourate has to be the Z2 and RE11A a close 2nd.

I've run the RE11 for HPDE the past few years with good results. I have not run the Z2 yet but if they are close the the Starspec I may try them next.
