Here's what I have so far: - The chassis flexes alot and needs to be made more rigid. Obviously a roll cage is a good way to correct this as well as strut braces. I've also read that there is a type of foam or epoxy or something that can be injected into the chasis to stiffen it up (I've read a few threads on this and am still debating whether or not its worth it. maybe someone who's had experiance with it can comment.) - The 2g suspension is a better design than the 1g. I'm not sure exactly what makes it better (still have alot to learn about suspension). Is it that the 1g's suspension is a bad design, or is it just not as good as the 2g's? - The open differential in the front kills us with understeer. A Quafe differential solves that, but I'd like to know what your guys opinion is on changing the center differential as well. - The 1GA's have those puny mickey mouse brakes in the front (mine are already changed to 3000gt's) - The car is a pig by nature, weight is a problem. Is there anything else that you guys can come up with? I'm hoping for all the road racers to share there personal experiance in this. What have you guys noticed are the weaknesses of a 1g car for road racing?
