Just an update!
My SLS is deleted.
I got adjustable camber links from Speedway motors
My LCA is like the RDM-TEK, 5mm shortened and installed with polyurethane bushes from hedgehog-motorsport.com
My Rear sway bar is also installed with polyurethane bushes from hedgehog-motorsport.com
My shock Absorbers are koni sports (26-1198S)
My springs are AMG from w210 E55 AMG (two yellow marks), 1/2 coil is removed and the pads are from a w210 as well.
Tie rod, torque and trust arms are with polyurethane bushes as well.
The subframe is mounted with two new sportline bushings on the rear.
I'm still not happy, the conors handling is ok - but bumpiness/roughness roads makes the rear end feel slippy.
So I might need to take the subframe down for inspection, the front subframe mounts on the chassis (on the picture) looks like a weak point to me, has anyone replaced those?
I consider upgrading:
The torque with aluminum from the T-model (210-350-37-06)
Installing #1 pads (8 mm) and if possilbe get a set of E60 rear springs from Mercedes
I also found out that these cars are extremely sensitive towards alignment, only a few can make it right!
(on my last alignment most hightec Hunter - they gave up after two attempts - and the steering wheel is still not in the center).
