I've been running them for over 6 months now with no issues.$240...http://www.performan...ingssingle.html Edited 17/07/12 10:45 PM by rbjet Link to comment Share on other sites More sharing options...

Sasha Member 141 Member For: 17y 6m 7d Gender: Male Location: North Queensland Posted 19/07/12 08:28 AM Share Posted 19/07/12 08:28 AM I have an early 03 BA Auto making over 300 with std springs. Who told you you need springs? What symptoms is it showing on the dyno or after a run? It's easy for people to say yeah get springs but they are not always needed and can be a costly exercise, no to mention a decent size job if doing them yourself Just be sure you need them first before you go buying a set.

The tuners told me once I they got it to 270rwkw it was gonna need springs without a doubt. They went another 100rwkw and it's still going strong!
