rear hub bolts and PSS9 set up

[Mad-Machine]

I got the fronts in and I need to do the rears tomorrow. To compound the problem, I need to replace one of my rear trailing arms.. anybody know what size the nut is that holds the hub on? My largest socket is only 20mm and it is far too small.. I want to say it is a 26mm? but I am uncertain.

Also, anybody recommend a setup on the bilstein shocks? My G/F is touring for the next 8 months with the Producers, so her comfort is not in mind right now. This is a daily driven Ti with no track pretensions.. I need a semi-comfortible ride (semi smooth roads) that is not too tail happy. I would prefer neutral.

Set up as follows... Bilstein PSS9 coilovers.. with solid (not offset) urethane front bushings, solid balljoint control arms, and stock top mounts.

In the rear I am running soft uprated bushings on the trailing arms, Urethane bushings on the subframe, and updated E46 RSMs

As of now.. I have it set at 4 on the front and 5 on the rear..
