I've had the Prodrive springs on my 03 STi now for a few months, but I've become concerned about the difference in ride height between each side at the back. It's fairly obvious to the naked eye, but I've also measured it to the best of my ability, from the top of the wheel rim, to the wheel arch. The right hand side is about 1cm lower than the left. This sounds like alot to me, but I just wanted some second opinions.

you drive your car with more wieght on the drivers side then the passenger, unlessyou ALWAYS carry a equal or greater wieghted passenger

its commen for the drivers side to sit lower, most of my older cars have, what i have always done is let the drivers side settle for a week or so, and then swap the drivers to passenger side around so the other side can settle ;)

The back ride height is effected by the rear spring top hats. These are eccentric so have to line up perfectly with the lower spring seat on the strut otherwise the spring gets slightly twisted. Thus the ride heights are slightly out. I spent ages messing about with these hats while fitting some new dampers and springs.

I would take it back to whoever fitted them and get them to sort it, or at least prove that they have fitted these hats correctly.

Yup, i think either way its going back to them, thanks for that.
