are E36's any good on the track, my mates are driving Caterham 7, Westfield Megabusa ( has a 1200CC Bike engine,0-60 @ 3.4s

), Lotus Exige, Lotus Elise and a Honda S2000.
I'm tempted to have a cane with them on a trackday,have a 323i coupe , UK, with M-Tech kit, suspension, body kit,17" E36 M3 replica's (profile ?) , otherwise stock, and 1385kg stock, they are running 500-750 kg's... what d'ya reckon ?
I think straight off I need to consider new air filter, exhaust , lower profile tyres , maybe anti-roll bar ?
