UPDATE
I was in the UK for a holiday last year and brought these back with me in my luggage;
SPAX rsx coilovers. Adjustable height and adjustable damping. Stainless steel adjusters and spring seats. Really good quality for a reasonable price.
I got the subframe and diff into the car. I had to then take it back out again because the lower and upper control arms couldn't be bolted in with the diff in the way. Rookie mistake. But second time is a charm.
Because there are 2mm subframe strengthening plates, there needs to be 2mm spacers for the front brace to keep everything correctly aligned. People seem to just sit a spacer in like a big washer, but I wanted to weld the plates to the front brace for a cleaner look. I got the front brace and a couple other missing subframe attaching parts from @BM WORLD so big thanks to Brent.
I also wanted to make some strengthening plates for the upper control arms as they are aluminium and known to fail with coilovers. So back to cutting up more 2mm steel.
I hammered them to match the contour of the control arm and then I sandblasted them and took them to @aja540i for Andrew to do his powdercoating magic.
Front brace was installed, and so was the control arm strengthening plates.
I have just washed and reused the rubber spring seats for now. When the car can be driven I can make a decision on what thickness replacement rubber seats I will use.
Springs and height adjusters went in easily.
Then it was the turn of rear trailing arms. I'm using 330i trailing arms that I got from zebra wreckers, so I can utilise the larger brakes, and larger bearings. Of course they were sandblasted and powdercoated like everything else. I then pressed the new bearings in.
New rubber bushes for the control arm attaching points, and powerflex bushings for the trailing arm to body mounts.
Then they were installed with the zinc plated bolts.
Rear shocks are next. The spax gas shocks got new top rubber mounts, washers, and custom stainless steel reinforcement plates and gaskets.
Starting to take shape, and I'm really happy how its looking.
Then the sandblasted and powdercoated brake backing plates and hubs were installed.
