I am using 17" QA1 DD shocks and 10" springs on the rear of my car and 15" QA1 DD shocks and 10" springs at the front. I have also dropped front upper spring mounts about 10mm giving about 15mm extra height at wheel ( 18" rim )
Thanks for that information.

At the moment I have 'crazy amounts of spring pre-load' so want to reduce that way back. I'll have to dig out the paperwork on what length shocks they are.

Car seemed to take the road bumps a bit better with the new settings, just need more time on the roads.

Found out that the ABS didn't work so I'll need to look into that as well.
