...its definitely the wheels. I run standard 17" JDM's in the winter and the car was fine... then i swapped to my 19" 'summer' rims and it started instantly. I think i started this thread that day...
Am going to call DPmotorsport where i got them from, or Wolfrace this week, as its too much of a problem, and they've not developed another fault (which i'll be starting a new thread on sooner or later )
