[s-cars] track tire recommendations

[Lee Levitt]

Thanks for all of the recommendations -- to wrap up, I scored a 
set of BFG G-Force R1 tires, heat cycled and used for 1 track day, 
for $400. :)

They should cover me for the rest of this year and all of next!

I'll run the race Dunlops for autoX through August and then swap 
over before the August event at the Glen.
