Yes that's it, but I had to drill out lower bolt hole to accept a cammed bolt, as the was no pivotal adjustment. How much were the cars you did this week lowered by ?
I still have the original tyres if you want to see the wear. Totally trashed on the inside edge. Done about 15k with an nice even wear pattern until I lowered the car. Within 1k they were down to the wire, front and rear, like the worst case of bad tracking you've ever seen. (Yes I know, poor on my part. Just didn't expect that amount of wear so quickly..ah well, ya live 'n' learn !!).
When I was booking the car in to have the camber adjusted I had to describe the kit I had fitted as they were adamant there was no camber adjustment as the standard settings for the Omega B was on the computer program for the geometric laser system they used, with a note advising CAMBER AND CASTOR NOT ADJUSTABLE...TRACKING ONLY.
There's a pic of the rear bush kit at:

A change in rolling radius would affect gear ratios and the speedo would not be accurate but that's about it. Camber adjustment was as a result of lowering the car.
You could fitted 18" rims with 245/35's and the rolling radius would be the same as the 15" rims with 205/65's as per the standard 2.5td.
(One day I'll get my post/replies down to a few lines !!!)
