Ok, fitted my Prodrive springs at the weekend and took me about 1-1.5 hours per corner, fronts were simple as to do but the rears were a different story with just not enough room to get the shock out, what I did was use the car jack between the lower suspension arm and the chassis and push them apart, once I worked out how to do that it was pretty straight forward and the shock came straight out.
If planning to do yourself 2 things you will need is a long (2ft in my case) breaker bar to crack open the lower nuts and an open open headed socket to undo the top strut nuts, along with some spring clamps.
Really glad I went for the Prodrive springs as I don't think the ride is compromised at all, turn in is much better and the car does not lean into corners as it used to, going to let them bed in for a few weeks and then off to get my fast road geo set up sorted.
Not really dropped it much, the car seemed to always sit quite low anyway and the rear has dropped 5mm and the front 10mm.
The front was 10mm lower on one side before I started work and after installing the new springs is still 10mm lower one side, I even took the shocks off again to check all was fitted correctly and it was, so I'm guessing maybe the car is slightly heaver at the front on one side, anyone else noticed this? I even measured from the wheel centre so tyres did not come into play, rears are perfectly level.
Anyway, really happy and would recommend these 100%, If your not that handy in a garage though leave it upto a proffesional to do as can/are quite a PITA, I was getting quotes of £200 up though to fit, hence why I did myself!
