I guess if you consider BMW has a multi-million dollar r&d budget. The suspension bits are about as good as they're gonna get.

What about coil-overs or spring/shock combos? The M3 parts will break the bank for me, but it'll be nice to have something to shoot for.
I think the increased understeer is due to folks putting on the E9x sway bar on stock suspension, especially the E93 sway bar.
