Hi folks I need some direction so i can make a decision on wheels.
I'm looking for new wheels for street and DE Events. Basically (8.5 x 18 & 11 x 18).
Tires 1. 235-40-18 (r25.4) and 315-30-18 (r25.3)
2. 235-40-18 (r25.4) and 295-30-18 (r25.3)
I noticed some rims come with inserts. Is it best to stay with wheels that are machined hubcentric. Hence no inserts ? Will the tire sizes work for AWD ?
The wheels will require hub centric rings which are provided. Im told this is not the best set up on a car for DE events.
thanks.... My car is lowered using x73 Porsche sport suspension. I dont want to roll rear fenders if possible. Hence avoiding 12 inch rims in rear.
Gunther, thanks for your DE feedback. I push the hell out of this car at watkins glen the inner loop and always clip some of the rumble strip. So I want to be sure i will not rub. I believe option 2 below will work (no rubbing) as you mentioned correct on 18 x 8 and 18 x11 rims ?
I have x73 suspension with some negative camber...
turbo twists with Sport Cup 315's for over 15 years at DE and track events with no issues. I have 245's on the front.
thanks Ed
awd turbo tire diameter options
225/40-18 - 25.1" stock
295/30-18- 25.9" stock
315/30 is fine on the twists and will fit 11's without rubbing. it's when you get into using spacers on 11's that rolling fenders becomes required. the increased plant, stance and ride on 12" rears is well worth the minor mod of rolling rear liners.
those in our gt2 sizes look like a terrific alternative to an equally yet no less useable wheel than the OZ. cheap but light, and durable. works for me.
never heard of these. would be great to hear of folks running them on this platform. good find.
I have a set of apex sm-10
18x9 and 18x12. Et 46 and 45
Plan on 245/315
Also lowered on kw v3s. I'll probably have to do some light modding to get it to fit perfect
As others have mentioned, we have great 18" solutions for your 996 Turbo which were designed specifically for the Porsche platform - no centering rings required. We have multiple fitments available depending on your goals for the car (how you plan to use it and what supporting modification may or may not be done), desired tire sizes, etc. Here is a link to our commercial thread here on 6SO for more info on the wheels: LINK
Although a 315 tire can safely be mounted to an 11" wheel (like the factory turbo twist), a 12" wheel will provide superior sidewall support for improved performance/handling. How much negative camber do you have dialed in, and is there a particular compound that you would like to run? I would be happy to answer any questions that you may have.
I'm with the guy above. If you want to stay 8.5 and 11, why not just keep the stock twists? I use them as track wheels with 245 and 315 wide rubber.
If you're spending money, go for 9 and 12 inch wheels.

Note with 315s on the rear I got rubbing on the inner fender liners (not in the garage, but on the track). 5mm spacers solved the issue. This with stock turbo twists.
