That has been another consideration. But I don’t really like the look of the over fenders enough to want to sacrifice the car ive decided. And as cool as a 315 would be, it presents some other less ideal obstacles. The larger 25.7" overall diameter is one of them for a couple reasons. The other issue is keeping the rear tires evenly heated so they perform. It’s possible to do I think, with dialing back to minimal camber (like -1) but not how the car sits. So I would need to find some kind of camber joint to add + camber ideally, or have to raise the car to stock ride height levels, which is a compromise im not willing to make. There is a lot of technical things to consider when you want the car to perform well for the track and even street, and if I start messing around with changing the set up, ive got to make sure im looking at all angles - Certainly expensive or irreversible things. I hate the idea of spending a bunch of money to still be left with more compromises then I have now. Minus the immediate tire availability issue, the set up is an excellent one, that’s why I did it. I think im just going to have to hurry up and wait some more.

 

Yes, and at least the wheel design would match.

Your still talking an average 5-6 week turn around time this part of the season to get the wheels widened and $1100 for the pair bought and widened, plus $700 for the tires? vs IF the Kuhmos were available right now, it would be just shy of $600 out of pocket delivered. So $1800 vs $600. The only guys willing to buy my rear wheels would be wide body guys that maybe want to run the 315/35/17. So a slim market on resale makes me not want to give them up either. Would ease the consideration if I could make $500 back on them or something to put towards the 18". I do like the idea of going with a shorter sidewall for less deflection.

 

You know the CF5 can be made in the sizes you want. Classic 5 spoke wheel.

I know still not the ideal situation since it would be a full new set of wheels but maybe something to consider for next year.

 

I've seen a few videos on youtube on japanese tracks where the V720 is nearly an entire second behind the RS3 kooks in best laptimes on a two minute track. But I'm sure we've all heard the rumors that the compound overseas is different then it will be here, so I will reserve judgement till then.

 

Hell, id run an all season at this point if they would make it in my size, just so i could keep the car on the damn road.

 

So I know this is back from the dead, but I read a Viper ACR review today and because of the praise for the tires I decided to check out Tire Rack - The 720s are out and are cheaper than RS-3 V2s. Anybody else try them yet? I haven't seen any mention on the R&C subforum.

On another note, now I'm kicking myself for purchasing closeout BFG Rivals in February.

 

I still have yet to see any credible review of them. I am also struggling with the V720 versus RS3 decision right now.

 

245/40 is the largest size available right now in 17's, so you likely won’t get any real good feedback until next spring/summer when the remaining larger sizes are released. If they are anything like the XS which they should, they will be a good tire and should have a firmer sidewall for more precise handing over the RS3, which are known to be the most compliant/vague handling over the other extreme summer line up. I suspect the v720 will be more akin to the Z2/starspecs in behavior.

 

Looks like Tire Rack finally concluded their testing:

Not bad at all, right in the mix there, and better then the RS3 looks like in most categories. Far better in the wet then I was anticipating. The new RE-71 is proving to be quite the bad ass tire. Too bad they don't make any big 17's.
