Anyone try upgrading their rear sway bar?

[hemants]

I have an early model P85 Signature and find the body roll to be quite high even on the lowest setting.

I know the suspension was changed and that it can be retrofit for about $5k but wondering if anyone has tried doing just the rear sway bar?

I thought the P+ only had a bigger front sway bar?
and maybe different dampers. I think the rear was bushings + arms

The + sway bar is the same part number as cars with coil suspension. In order to change it the drive unit needs to come down, changed mine when drive unit was being changed.
