245/40-17 a7 - fits?

Hey all, I can't tell through looking at threads. Sounds like TomR regretted getting 225s.

So - anyone running 245/40-17 a7s under an Elise?

I have 235s on the rear of my S260 right now, and I've had 245s on my 240S with very occasional minor rubbing.

Hmm, the a7 does not appear to come in a 235. I'm asking specifically about the Hoosier A7; I know Hoosier A6s in 245/40-17, as well as many other 245/40-17 fit just fine.

However, the Hoosier a7 "grew" relative to the a6; a7s tend to be comparatively larger than a6s, despite being the "same size."

So - have you run *Hoosier A7s* in 245/40-17 with only minor rubbing?

Thanks!

I have a 211, so not exactly the same but I'm running Ethos wheels with Hoosier A7's:
205/45zr16
245/40zr17

They are wider than the A6's for sure.

I ended up getting 225 A7s, but I just met a guy with an Exige with 245 A7s on Ethos wheels that seemed to fit without rubbing. He was on Penske DAs. Handled AutoX duty without any issues.

I am running 245 R7 on my exige with the TD1.2 wheels from BWR and 2 large BWR spacers. It fits in all but the worst bumps where the tire hits the front inside of the frame. I will be taking out some camber in the rear to help with this and with tire wear. At 2.3 degrees now I think.

Yeah, the BWR spec Bogarts really make the most of the available space. I'm running -3.5ish in the rear and they rub a fare amount. Never noticed any drawback to the rubbing though. Who cares if there are marks on the frame?

Just put the A7s on the car. SSRs, 16x6.5/17x7.5 with max-allowable spacer, 2.2ish degrees negative camber, toed in 3/16", plenty of room. One of my rear fender liners is chewed up from who knows what, the tire grazes that, but if it were in normal shape, no problems. I put a fair bit of load on the tires driving around, certainly not as much as they'll see at an event, but no weird noises/issues.

245/50-17 A7s fit, by my definition. Elise, stock bodywork, stock ride height, LSS springs.

Thanks!
