have not really seen a thread about suspension characteristics with focus on spring stiffness and ARB sizes and how well they work together. intent is to not go into toe, castor, camber, stance etc etc etc
Vehicle: 1989 E30 325is 2dr Series II
Weight: basically stock 2811 lb (per BMW Owners manual)
Engine: m20
Use: street
Setup (coilover or replacement): GC coilover
Front spring stiffness: 375 lb/in
Rear spring stiffness: 525 lb/in
Front arb size: IE 25mm full soft
Front ARB links and mount (CA/strut): (stock on CA)
Rear ARB: whiteline 16 mm full stiff
Rear ARB links: whiteline
Wheels: 16x7" x 4
Tyres: 205/50/16 Michelin PS4
Comments:
cornering neutral to a tad amount of oversteer at the limit. however it feels unbalanced/lagging FR to RR on quick transitions . i'm using a relatively small rear bar compared to others but bigger rear bar would seem to make it more oversteery at the limit. will play with koni SA settings to see if it improves transition.
