Coloured springs did come with the carpet version & also on 09/T3 foam versions

08 + onwards have a shorter shock length than the previous 07 + earlier models & coloured springs are a pooftenth longer than blacks, which may suggest why you've got the ride hight problem

Xray black springs should fix your problem & come in 2.2 (equal to whites) to 3.4 (almost as hard as purple).... i'd use 3.0 in from & 2.8 in rear for carpet

You should be able to get all this info off the TeamXray website
