I agree, I race in several District races around my region. I put in a few 4 wheel touching cars and win by several car lengths. Afterwards I have a few dad's at my table asking how my cars are so fast. When I give them detailed information and show on my cars the how & why, they look at me like I'm talking chinese... I offered to give a workshop next year, we'll see if a few districts take me up on it.
A side note venting session: next Saturday is my hometown District race. Last year at this race (Open class) I put in a legit 4 wheel touching car (3.00 time oil car) and 2 guys put in cars that ran 2.98 using graphite and blew my doors off. So this time I'll run tech inspection and if I see their cars are 3 wheel I'm going to let them pass (they like to argue at the table). I have a couple "Hot" 3 wheel cars I'll put in that I'm confident they won't beat. I hate to do this, but these 2 guys (in their 50's) have got away with cheating for a long time. As a test, last September at a local race on the same track, I raced them with a 4 wheel touching car with 4 Intimidator wheels, 4 fenders and runs a 2.98 time. They raced a 4 wheel car, one wheel raised barely touching and using graphite and beat me with a time of 2.97
