Trackday suspension

[buffly]

Have a 325 that i use for abuse on the track, but is fitted with Apex springs and struts(only about Ԛ£200). Not too bad for the road, but way too wobbly for the track. The car simply rolls too much! Wondering what you folks use for your e30`s, wether it be a conventional spring/strut setup, or go crazy and fit expensive adjustable coilovers? Any recommendations on manufacturers? Not much good looking on the net for suspension, as i would rather have advice from anyone who`s actually bought, and used uprated kit. Cheers fellas.
