Well I went to the local Super Target a couple hours ago and picked up a Microsizer blue Impreza

. I love this thing!! It's so cool looking, and pretty quick, although soon I want to upgrade.
What upgrades should I look at? I'd like to first focus on speed, then maybe I'll get the improved suspension kit. So which motor would be fast, but not so fast that it would flip or spinout or anything? I'm a total newbie, so I have no idea how many rpms would be fast enough.
HAHA!! I feel like I'm 'in the loop' now! Now I can talk about Microsizers and understand things because I have one.
