For all you cats out there looking at new springs I can tell you that the Espelir ASD will not disapoint. I was of the first guys from World One to install a set of the ASD springs back in March. Going from stock to the ASD is an awsome experince. The ride is actually less bouncy on the Espelir springs than with the stock units. Also the turn in is superb! I've got a perrin rear sawy installed and it was fighting the stock springs around every corner. I could feel the car buck and bounce when ever I took a corner "spirited." Now with the ASD the grips like a freaking cheeta and rips around corners better than anything I've been in. I have total confidence especialy in quick hard 90's and off camber corners.
I was going to get the Prodrive's but Garrett talked me into trying the Espelir's and I'm glad he did, what a spring, plus he gave me a bitchin' price on them since I was one of the first to get 'em. So I'd say get them they're deffinently worth the money, even if I had paid full price I wouldn't feel any diffrent about them.
