Is it beneficial to run with 18's for DE?

Basically I'm considering buying new rims for my car, ie. Fikse or Kinesis in 18"s.
Or should I just buy standard 993 17"s with DOT spec tires?
TIA.

Robert - Thanks. I knew better. My bad.
DJF1 - I've been on TWS once in a friend's 993 and a couple of times with my motorcycle.

I strongly recommend running 17s on the track -- be they on oem Cups or lighter aftermarket wheels. You probably won't notice the difference between 17s and 18s. More importantly 17" tires are cheaper - you'll thank us later.

I met Haas through Dave Mundy, and PCA events; he's been instructing at DEs for quite a while.

let's spend a second on the theory about 17" vs. 18" wheels.
- The lighter the wheel the better
- The larger size wheels provide stiffer sidewall resulting in better turn-in
- The smaller the overall circumference (height of tire+wheel) the less energy it takes to turn the wheel a rotation
- The less tire width you have (in the rear) the faster you accelerate but handle worse. so this one is a trade off
- The larger size wheels correspond to less tire weight (assuming you are maintaing the same overall circumference).
So assuming this is correct & that you are not optimizing for cheaper tires but rather performance. would it be reasonable to say:
- the technology hollow spoke 18" wheels weigh less than the cup wheels.
- the added width of tire sizes may slow your acceleration a little but make up in imporved handling.
- the 18" tech. wheels will provide stiffer side walls
so for the most part i would say that 18's are superior to 17's.
what am i missing?
Cheers,
Boris

As one who runs 18's I will say the tires are much more expensive. And while there are the advantages cited by Boris I don't think you'll be able to tell the difference- and this is after all a DE event and not a race.
Having said that I would buy the lightest strongest wheels you can afford. A number of folks have told me about Porsche replicas failing at DE events although I've never seen it myself. And I do think you could tell the difference between a heavy and light wheel given the same tire- I know I could.
