A cooler is a great addition if you track the car heavily. Other than that it's not really necessary. I have a gearbox oil temp gauge and under normal/spirited street driving gearbox temps stay well below 200F with the cooler off. At the track the cooler keeps temps below 220F during a hard 30 minute sessions. 260F is where you need to start to worry.... For general DE stuff with 20-25 min run groups, you'll be below that even without a cooler unless it's very hot outside and you're really punishing the car for extended periods.

thanks for all the knowledge, just trying to be funny. This is a new car to me after many years in a RS America (RIP) and an NA 996, I have a lot to learn about the car both mechanically and how to drive it fast, it is an adjustment to the AWD and all that extra power. I have learned already that it really goes through front tires 2 or 3 times as fast as my other cars.

With AWD, get the NT01s in a 245/40/18 and 315/30/18. Those are the correct diameters and the tires should be available right now. I'd get a spare set to throw in the basement as Nitto has a tendency to sell out with frequent indefinite backorders. Those tires are the best bang for the buck choice out there for a DOT R compound.

thanks will give them a try, just trying to find a better tire than the Toyos that dont cost a fortune.

^^^^+1. I track this exact NT01 combo on my AWD 996T on stock rims and it handles fine. You may possibly just need some 5mm spacers to go with them but they're probably fine as is.

Wow, I'm impressed 245/40/18 and 315/30/18 fit. You guys have your fenders rolled? Looks like BFG Rival S come in this size too. Anyone tried those? Trying to figure out what next set of tires will be for my car (AWD). Was thinking AD08R in 235/40/18 295/30/18, but curious to hear what folks are having good luck with.

Another NT01 235/315 user here. I had slight rubbing on rear fender liners (only at track, I guess due to sidewalks flexing under load) so added 7mm spacers rear only. No issues at the front, though it did require a little alignment tweak to prevent rubbing. No fender rolling required. This is the best setup I know of for AWD and stock wheels. You'll want longer wheel bolts with the rear spacers for safety.

I guess I missed the memo a while back that they should be 245/40 in the front instead of 235/40/18 with the Nitto NT-01 315/30/18's out back. That's what I've been running for the past few track days. It's been working but I sure wish I had more tire up front. I am using four-wheel-drive

You're right, 235/315 is the right setup from a diameter perspective. Corrected post above.

I run 5mm ones all round and am at ROW M030 ride height. Think spacers are only needed at the back though, as jayzbird says. I also heat gunned my rear liners and pushed them back in a bit tighter. I rolled my fenders (heatgun and padded hammer plus tons of patience - will be the baseball bat next time I think) in an effort to go wider againl but 265 fronts proved too aggressive (lost a lot of steering lock) with the stock front uprights.
