Well I had some some research and reading and decided I was going to use a set of Nitto NT-o1s on my 996 GT3 in 245/40/18 front and 315/30/18 rear. Unfortunately They are all sold out with no ETA on backorder from Nitto. I also can't go with a 235 front and 305 rear because the 305s are sold out.

I need tires because my stock wheels came with terrible Rossos on them and the Volks I have now are shod in a set of Michelin PSC's 235 front and 295 rear but they are shot, past treadwear bars.

So now I can either pony up the big money for a 235/295 replacement set of MPSC, or go with a set of Yokohama ADVAN A048's or Toyo Proxes R888's.

So what do you guys suggest who have used these? What size should I be looking at for each particular brand?

These will be used on a GT3 that sees some street use but this tire purchase is geared toward trackday stuff.

Thanks!

I ran Hankook TDs (235/295) on my 6TT and thought they were pretty good out of the gate. Not sure their availability but worth a look.

Just get 235 nitto's. Despite me thinking I'm giving up front grip with the 235's vs 245's the data doesn't lie. There's very very little difference in grip there are two turns at my home track where I give up 1 mph the rest of the turns I'm not loosing any speed at all

This is on a 9" front wheel. And lots and lots of data with nitto's.

Where are you finding the Nittos? Also, I've run 235s before and can't tell the difference versus 245s in front. Is be happy just to get a set.

Problem right now is that I can get 235 fronts, but the 305 rears are also out of stock.

So Nitto 18" 245's and 305's out of stock, national backorder.

I can get 235/40/18 fronts and 315/30/18 rears, would that work?

I know there is some measurement you have to adhere to to not confuse the ABS system right? What is the calculation needed for this?

*Edit * I might be able to get a set of 235/40/18 and 305/30/18, will that work correctly with the ABS?

I run 235 / 315 with no problem.

the 305 rear is a 35 series...it's too tall for our cars, if anything that's the tire that will mess up the ABS. I know a couple here have stated they had success putting the 305 on the rear of their cars but my friend tried it and he's slightly lower than stock and the tire rubbed because of how tall it is.

235/40 is 25.3" tall
245/40 is 25.5
315/30 is 25.3
305/35 is 26.4

run the 235/315 combo you will be just fine. I do have data that shows the 245 is marginally better...but I'd venture to say it's worth maybe a couple 10ths a lap at best given my data and my car setup. Now if your car has a good bit of push in it already your car might suffer more than mine. I made no setup changes and it didn't really effect balance. My car is pretty neutral though.

I have a set with low usage on them that I posted for sale a while back. I never did meet up with the fellow who was going to pick them up from me, and I never got around to re-listing them. My old ad is here:

For the last year I've been tracking 245/40/18 and 305/35/18 NT01s along with 245/40/18 and 315/35/18 V710s. Performs much better than the short 315/30 rears. No issues whatsoever with ABS. None, zero. Numerous guys in my area with some fast 6GT3s have switched to this combo and love it. If your offsets are right, you won't have any rubbing. I have no rubbing whatsoever even at 96/120 ride height. If anyone needs these tires, I have 8 sets of the NT01s and 5 sets of the V710s in my basement..

Hi Powderhound,

what is the difference/issue that you found with the 315/30's?

Thanks
