I don't have any issues with wheelspin, but then again I don't drive aggressively on the road. My only problem arose at the track. Gear selection is really hard. I've been told I need an engine torque damper. Engine can torque load which also moves the gear selector. Changing down into 3rd would either jam or slide across into 5th. Headers also hit heatshield fitted to steering arms under brisk acceleration.
