I have 18" allegeritas in 8" and 10", and my stock MY02 5-spoke lightweights that came with the 40th. The OZs are much lighter, but the paint scratches really easily and I imagine they wouldn't survive a ton of abuse. The price wasn't bad, though, and they've been great for autocross.

Yeah, I'd generally expect the wider the wheels, the better for track use. But I'd be a bit concerned that if the rear wheels (and tires) are too much wider than the fronts, the car becomes unbalanced and understeers more. I searched some tire threads a while ago and a few people mentioned that their car became more fun with narrower rear tires. I think I remember at least one guy going down to 265s (presumably on a 996.1), and at least one other going down to 285s (presubably on a 996.2). So with 11" rears, I guess I'd want 295s (or wider?), and I'd therefore want 235 or maybe even a minumum of 245 on the 8.5s on the front - and I'm not sure that works ...

255/35/18 will fit on 8" fronts. 245/40 fits a bit more easily. You can go all the way to 315 on a 10" rear, too.

I use a 235 / 315 combo on 8 & 11" wheels with nt-01. Love these tires but I Can't find 315s any more. On back order for months. I'd decide what tire you plan to use first based on availability and then match the wheels. Rarely if ever do you see wheels on back order.

depends on how you define fun...

I run 8.5 and 11" wheels on my 02 996 PCA J-class race car... fun for me is a well handling car that is fast on track. I run 245 fronts and 315 rears in Nittos, and occasionally run Kumho V710's in 245 F and 285 rear (super fun due to the smaller diameter which acts like a ring & pinion upgrade!). The car only understeers when the tire are corded or heat cycled out - oversteer is a much bigger animal with my car.

Regarding tires, I'm sure there are hoosiers that fit, and plenty of slicks, too. I think the 8.5 and 11" sizes are stock GT3 sizes, if that matters any.

Knfeparty, are these tire widths (245 or 255 front, 315 rear) on the 8 and 10" Allegeritas, on the 5 spoke lightweights, or both? (Presumably both if the offset is the same, but not sure if that's the case.)

When I got my car, it had 225 front and 305 rear on 19" wheels. Way too much under steer and too low profile for anything other than cruising. I quickly replaced the stock wheels with 18" OZs and now run 245 front 295 rear R888s and the balance is perfect. Haven't experienced any problems with the OZs yet.

I have 3 sets of wheels/tires with one 245f/295R and visibly they have a closer contact patch front to rear however the 245 does exhibit slightly increased steering effort.

Also to note that not everyone might be able to fit a 245 front without rubbing depending on their wheel/suspension setup.

Do you think there would be any trouble with PSS10s? If the car is not lowered more than with the X74 suspension (which I believe means 30mm lower than ROW)?

alpine003

No trouble with most coilovers assuming your wheel width/offsets are optimal. There's a slight chance you may have to run 3-5mm spacers depending on your wheel/tire configuration. Some 245 sizes actually have a wider "contact patch" than other brands so YMMV.

Also camber settings can be played around with to allow wider tires. I'm at -2.8 in the front which prevents rubbing. The tire has a lot to do with it also, the r888 has a lot of rubber and is wider than others for the same spec.

This was on the OZ, but I got the exact same dimensions as the 5spoke lightweights. I ran 5mm spacers in front to keep it off the struts. Front height was the issue; it wants to run the front fender liner above the rad vents, and also the bottom of the spring perch. 245/45 is really too tall, for example. I ran stock suspension in the front with as much camber as I could get, maybe -.7, and the rear I ran -2.0. The rears fit much better than I anticipated.

I went with OZ Allegeritta in 18x8 and 18x10 with 225 & 285 widths. I chose these due to the strength and light weight. I stayed with 18", read they're all around better than 19" for the 996. I ordered these in November from TireRack and took 3 weeks to get the fronts and I'll finally get the rears today. Long backorder on the rears. Seems they don't stock many.

robbieracer, can you post some pics of your car with the new track wheels?

Anyone who is willing to post pics of their car on their track wheels would be much appreciated!

I'm looking for some lightweight 18 in track wheels myself..

robbieracer

Here you go. Notice the fronts and rears color don't match. The fronts were manufactured Dec 2013 and the rears Oct 2014. TireRack was great and sending me a new set of fronts and should have them Monday.
