Hey Tunnelhead...
You sure you wanna turn a bunch of Minis loose in your nice shop? You might want to put something in front of the glass.

It could get ugly really fast once you get a few out there.
I raced with you guys at the last race at SLO high school. You guys have a great program, I had a really fun time. I was the guy racing the slow R40 and the fast TNX...LOL Keep us (me) posted on the mini deal and I'll try to make it out there. I have an M03 Mini Cooper and an M04M Alfa (not at the same time...

)
You can use any Tamiya shocks on them. If you use the TRF shocks, you generally use internal limiters and short springs. Oh yeah...forget the Sport-Tuned motors...just use regular-old Mabuchi/Johnson silver can motors -- they come in the kit and they're plenty fast to have a good time at no extra charge.
