Looks like I will be lowering my MC sooner than planned!!! ...whilst removing the rear disc for replacement I found that the nearside spring was broken. Judging by the rust on the break it's been broken for a while, I was oblivious as the car looked to be sitting level . I'm looking at fitting Eibach's part no. E10-20-010-04-22 these apparently lower the car by 20mm at the front and 10mm at the rear as I don't want the car to sit too low as the roads are pretty poor around here.
