well the BFG tires are as tall as the RA1's but much wider so we had some rubbing issues and the car seemed inconsistant close to the limit. I am switching back to the toyo tire for the next few months.. I had to run a huge spring and tons of spacers to keep the front from rubbing and the car just didnt want to turn. I am planning on a few DE events to test in the fall and racing again in Oct. I know the car when set up will run 2:10's or less on a good day.. dow its just getting the driver there (mid 2.13 is my fastest)
