Well... we had an awefully good showing at NHIS in the Z3 considering. I'm really starting to better understand the car. We are too heavy or others are too light (Acura's) but I do feel more strongly that the car has potential to be a consistent top 10 car. We have admittedly done little in developing the car as we had some computer gremlins for most of the season. I might reconsider my stance on the Z3 if I were you. It is a fun car. I'm also amazed at how responsive it is to tire pressure changes....I think that's where I was most off in my race prep...I just simply had my pressures way too high. MW makes a very solid and very reliable car it is a good starting point.
ps. Rookie season -about 12 races in and no DNF's. That says something about the car.
Good Luck
Rob
