Ran mine with the shocks at the rear of the arms and the Dimec20 chassis yesterday at Broxtowe. Car was excellent even in the wet. Started to snow before my first race so I put BB greens on all round and I could go at speed into corners and the rear just held. I've got my first 2wd regional there next weekend and I'm going to leave it as is.
Only down side was my crap driving and i ended up breaking my gearbox casing believe it or not
