The tire situation isn't a problem for myself. I have 93 Cobra rims that have Nitto DR's on them. I also have a set of Pony rims that are just sitting around. I can afford to buy the ET's and put them on the pony's and then I can just swap wheels when I go to the track.
As far as the suspension goes, yes I need springs, shocks, subframes, and control arms. There is no way I'd launch with ET's with a STOCK suspension

. The ET's are just another part of the puzzle that I need. And since they will be on a spare set of rims, I could get 2 years out of them with little problem (about 25 runs per year).
Hopefully, the suspension will be done by April when the stang comes out of storage.
