+1 for the prodrives, overall they make my car look and feel great.

 

a lot of people have good things to say about prodrive springs. Because they were a bit expensive for me when i was in the market for springs a while back, i ended up with a set of eibachs springs.

The eibachs sag a bit in the rear, but performance did increase a noticable amount.

have you checked some of the reviews on suspension here on i-club?
there's also a decent amount of reviews on www.subarureview.com

goodluck
