How's it going R.
I still have one that I use as a second 17.5 tc. I'd like to actually use it as an asphalt car,if I can get the time to drive out to some outdoor races.
On carpet, the aluminum bulkheads and toe blocks are very useful in making the car more stable and consistent.
However I believe that a bone stock zero S for asphalt is actually going to do well. From my experience, an "outdoor" car can benefit from a little more flex and ride height.
