I have ridden in a couple cars with the Bilstein sport / h&r springs and they were pretty nice.

I've had both brand new M030 and old leggy M030 but prefer the car as it currently is on FSD and -10mm M030 spec H&R springs.

cool. anyone know the difference between 986 and 987 front sways? otherwise, looks like you could put together an aftermarket m030 system w H&R springs, bilstein sport or koni fsd shocks, and used cayman rear sway. perhaps h&r front sway in a pinch (heavy though, and the h&r rear sway is too stiff unless you like a loose twitchy back end). total cost would be more than you could buy the actual m030 kit from suncoast, i bet.

edit to add: perhaps you could run a cayman front bar with aftermarket drop links? would still be less $ than running a gt3 bar ...

I'm pretty sure the 987 parts are a bit wider than the 986 parts. Either the spots where the bars mount to the frames are wider or the full widths of the bars are greater.
