Also, Rennline has spring hats for the rear that are flatter so the stud will penetrate the mount better.This sounds a bit pornographic, Jezz, I'm going to bed, cheers,

You've got to be careful w/ the shock lengths, the last suspension i had on mine w/ normal length shocks made the stud protrude so far that it interfered w/ the mono-ball mount which had to be clearanced, bottom line reaalu low cars need really short shocks.

Viggo,
The hubs have to come out, the angle will be to much for correct alignment on the holes of the hubs for 70mm studs, you have to punch them in straight with the center line of the stud hole.,cheers.

The front has a nice cut out in the hub so it's not a problem. No chance in the rear. There is barely enough space for getting the stock ones out. Not even sure if you can get a 60mm stud in there.

Take a closer look at your drop link location relative to Bill's. His is to the outside of the sway bar and attaches to the inside of the bracket. Your location on the bracket puts more twisting moment on the bracket causing it to turn on the shock, which will result in a broken drop link.

Finally everything is done and aligned. Couldn't lower the front passenger side below RS + 10. The lock rings on that end are already at the lowest position. It's corner balanced so the driver side sits even higher without me in it. Hope everything will set a bit with some driving. Anyone has idea why that might be? We checked to make sure the springs have the correct part number. The strut mount is set up correctly verified with Rennline. The A arm mounts were loosen when setting the ride height.

Closing thoughts:
+ Turn-in is super fast, bump steer is all gone, more front end feedback, and require a bit more muscle to hold it at high speed curves. Grip seems to be higher overall, with the front just dart to where you are pointing, and the rear is very well planted. There is absolutely no problem with the ride, in fact it rides better than what I had before.
- It wanders a little at high speed straight line flat, and something is still a little out of phase (yaw vs roll) at very small steering input. There is also quite a bit of influence on yaw based on throttle input at low lateral. I'm going to put another 100 miles on the car and check alignment again, especially the front toe and caster. Hope the suspension sags a bit also.
For reference this is the setting: RS+5, RS alignment, Conti ExtremeContact DW, Middle position for both front and rear sway, 5/5 on PSS10.

IE: RS Ride height is:
Front 124
Rear 107
The tolerance is +/- 10mm
When we consider the Tolerance we get a range of acceptable heights being:
Front: 114 to 134
Rear: 97 to 117
To me when someone says RS +5 I think of:
Front: 129
Rear: 112
