My guess from his profile and sig. pic is he went with coilovers...
Lowering springs are great for the street but if youre into autocross... and you do it a lot, coils are the way to go!
AND... for a sale bump... i have had Eibachs for over 12,000 miles and they are great. No issues what so ever and the installation is a snap. Great price too... GLWS
