Does anyone have the part #'s (and specs) for the ROW suspension pieces for the 996TT ? I drove a friend's car which was fitted with a spring kit from Champion, and I was not impressed. The car was lower, but seemed to have quite a bit of roll and felt unbalanced in some corners.

The ROW suspension consists of different springs, dampers and possibly a difference set of compensating spring plates. The workshop manual discusses two sets of color coded spring plates, but the manual is not clear about which are required for a ROW setup. For a good source for these parts, please email me.

Here are the alignment settings:

Front
Spring constant USA and ROW 33N/mm (~190lb/in)
Ride height USA 158mm +/- 10mm
Ride height ROW 138mm +/- 10mm

Toe USA and ROW +5' +/- 5'
max difference left to right 5'

Camber USA 0' +/- 15'
Camber ROW -30' +/- 15'
max difference left to right 20'

Caster USA and ROW 8d +/- 30'
max difference left to right 40'

Rear
Spring constant USA and ROW 60N/mm (~340lb/in)
Ride height USA 158mm +/- 10mm
Ride height ROW 148mm +/- 10mm
Toe USA and ROW +10' +/- 5'
max difference left to right 10'

Camber USA and ROW -1d 25' +/- 15'
max difference left to right 15'
