i have previously used spax and jamex springs which i thought were rubbish on my tourer i bought a spring and shock set up from belguim which i wish i wouldnt have ok the car is almost on the floor but there is no play or ride quality i am now in the process of purchasing koni adjustable shocks and springs and will see if these are any better in my opinion getting the right set up for your suspension is 1 off the hardest jobs on the car as most people like different ride sensations and taking advice from other owners is there own preference but 1 thing i will say is that no matter who or where you go and speak too the same answer always comes out spend a lot of money on a complete kit not just springs
