I have 275 60 15 BFG drag radials on my duster. They worked very well in the 2 events I entered. The front 235 65 touring BFGs however were not the hot ticket. The drag radials are very controlled when braking loose.
I took the advice from the regional champ tire PSI, seating position, braking points and lines etc. He thought me to be a NON driver, after his run in my car he complimented me on car control considering its lack of balance and poise. His critiqe of car was why would they use a box that takes near 5 full turns to go lock to lock. His next was the brakes a bit firm but excellant for their vintage. Nice guy for a mazda guy with tea and crumpets on his menu.
