Hehe...well i guess fine tunning of handling mods is really difficult...but once perfect set up is done..u probabilily will acheive a best timing on track...
To start off: All bars should be presents, follow by suspy, ARB, LSD, brakes and tires...if still cannot, get reinforce arms, cluster, camber bolt, end links or spot weld ur chassis...which by the way i know a place which does good spot welding ...interested PM me...
