I've done a couple searches and came up with results other than what I want. Anyhow, I was wondering if anybody uses 17" track rims for a NB 996, why i want to use smaller diameter rims is because of the amount of tires I go through in a season, I want to be a little budget conscious on that respect. I want to get the widest set of rim without having to roll my fenders. What is the optimal offset to rim width for these cars. Are there any brands you suggest that make 17" track rims? Anyone ever try putting a set of stock 17x8.5 et 50 rear rim in the front?

 

You can try CCW. They make extremely high quality wheels and are involved with making custom offsets and sizes for many different track and race applications.

I had a set on my M3 and will likely be picking up another for my Audi.
