Dont worry about breaking things. There is only one wall at Wakefield and its on the straight. Just make sure you got enough tyre tread, brakes, brake fluid topped up if needed, clamp down your battery and budget to do an oil/filter change straight after. I've been there 3 times with standard ECU, brakes, SMIC, cat back and 17's. Had a blast as you can see from the piccie in my sig. (turn 8)
