Seems to be coming together well, hope you're pleased. I know I've said it before but I do think the GAZ setup is the best option unless you're spending 3k+. What spring rates did you go for as I know the m3 is a heavy lump(more so than the standard one), are you using the 6 speed box?
Also can you post the details of your blasting mate? Looks like a good job and saves me hauling the shell about!
