The springs are a nominal drop of 40 at the front, 35 rear I reckon there is enough clearance on the bump stops, I'll look at them again now its been run for a few miles.
I used DOT 4 to re-bleed the brakes.
The fuel filter is underneath the car, right in the middle. Its easy to do, I tried two pattern ones, both were the wrong size. I couldn't be bothered to alter the bracket so bought one from Fiat.
Powerflex bushes are good, the car is rumblier than before, but not noisy. There again it also has very stiff progressive springs so I altered more than one thing at once.
