I have a chance to purchase a 2004 M3 with SMG, 23k miles, and the AA stage 2 kit. My question is can the SMG handle 600hp? Or how reliable is the kit? I've searched but haven't really found any info about the AA kit that's not from a vendor.

I really like the HPF kits which was my first intention and might still go that route if I can find a decent milage E46, but this car is in excellent condition. So AA Supercharge kit yay or nay?
