Too much body roll?? Have you driven a lot of other cars in autoX? When I went to autoX school, I had 3 different instructors drive my car and they all commented on how great the car handled and that there was very little roll to it...guess it's all relative.
im not saying its worse than other cars... i had a 2001 VW Golf TDI and that thing was terrible with body roll... i think the mp3 is amazing and handles great and has not much body roll but i want to make it have virtually no body roll.. when i get my Mazdaspeed coilovers im getting custom sway bars.. probably 27mm front and 24mm rear... and im getting a front subframe mount... i want this car very stiff...
