I have been driving to the track on Dot R compounds for 5 years. NT-01 or RA1 can be driven to and from the track so no trailer needed. If I were only running DEs and not competing in Time Trials, I would probably stick with Hankook RS3 tires. The lap time difference is not that much and they are better all around street/track tires.
I do have a few friends who always trailer their car and roll out a fresh set of R6 Hoosiers for every DE day. $1600 in tires poof gone! More money than brains I guess.
