I just got a chance to practice today with the locked front end with foams and it was really good. The car was very consistant from the first time i set it down. My setup was close to what I had run with the original parts. The only change i would like to make is to get the car to roll thru the lower speed corners better, but I think i could make a caster change. I have 6* total now, so going to 4* might be better. Definitely something to try.
