Yeah this pretty much sums it up. It really depends on your definition of race tire. If you are class restricted to a 200TW setup, 19" is definitely the way to go. You have those tires mentioned above, plus some R comp options like the Nitto NT01 and Sport Cup 2, among others. The only two solid 18" R comps or 200TW tires that come to mind are the 305/35-18 NT01 and the 295/40-18 Hankook RS4 (too tall for some).Options for slicks (Hoosiers, Pirelli takeoffes, Continental surplus/discontinued tires) = good 18" selection.
Newer wide fast street tires (Goodyear Supercar 3R, Hankook RS4, Bridgestone RE71) = better in 19s (305/30/19s)
Take your pick.
Cory, can I make a plug for some face 3 18x11s SM10s? Curious to see how much lighter they'd be than EC7s and I like the knurled beads. I'm sad the et52 18x11 EC7s didn't make the cut for face 3. Would have looked cool.As an added bonus, our 19" SM-10 wheels come in at a very comparable weight to our 18" EC-7s
Good news on the 200tw 18" tire front. The new Advan A052 (which may be faster than the RE71R) will come in the following sizes... 275/40R18, 295/30R18, 295/35R18 and 315/30R18. I plan to run the new A052 when I get a set of 18x11 EC7s.The only two solid 18" R comps or 200TW tires that come to mind are the 305/35-18 NT01 and the 295/40-18 Hankook RS4 (too tall for some).
O myMore and more SM-10 wheels have been heading out the door lately. Doris from Women Driven recently put this R spec staggered setup on her GT350 and wrapped them in Goodyear Supercar 3R tires that are ready to hit the track.

Threadjack- Apex 18x12's? set up square w/ 25mm spacers on a S197?
I have the full Cortex set up and recently cut the back bump stops and did the relocation mod. I now run Apex 18x11's square with 15mm spacers rolling Pirelli 315's.That's what I run now, but I think 18x12s would be a pretty small segment for Apex to push.
To make 12s work, I used offset struts up front. The back has OEM configured shocks+springs/Watts link/bump stop bracket mod.
Unlike 18x11s, 12s take some mod work and you have to hack a Cortex setup together/apart to get the room up front. Tires fit under the fenders though and I think there's room for 13s with 335s in front. 13s in the back will poke and may take a fender pull to look okay.
Nothing on the books for now. Hoping to get to something in the next month or two.I have the full Cortex set up and recently cut the back bump stops and did the relocation mod. I now run Apex 18x11's square with 15mm spacers rolling Pirelli 315's.
Aways hunting for more grip.... Are you going to the 7/3 Sonoma or MiniNats?
