I have enquired around and awaiting responses from Eibach and Tein. Apex and G&M apparently do not make springs for the YRV Turbo. So far these are the responses that are available:
25mm lowering springs:
PI springs at £129.19 delivered
Spax at £116.22 delivered
The above 2 are from www.hrsuspension.co.uk
Anyone had experience with these 2?
