I know nothing about Evos or setting up an AWD car. You may want to head over to sccaforums.com and see what the popular setup is in BSP.
I have to second what Chris said though. The tires will make a huge difference, plus a proper alignment. I'd probably go with some Kumhos though, they'll last longer.
Yea problem is almost all the BSP Evos are VIII & IX. Hardly anyone has tried to build a strong X due to the extra weight

Sucks that you can't set up an AWD car Justin. Was hoping when I got these coilovers, you'd help me fine tune it lol.
