About to head to my first trackday in the GTR and need to get the car ready. I have done several trackdays in previous cars and always used XP-10/12's with great success. I have found it harder to get to the track as often and was thinking I may be able to pull off a track/street pad compromise. I have read about 6 pages of previous posts and think I will go with the ME-20, or should I go with the MX-72 ? I may make 3-4 events a year (blue/red group) and dont mind a little noise if needed on the street.
