im in a stock gze. i use 2nd gear around archerfield all the way. for those that dont know archy youtube it. its a tight go kart track. i will almost hit limiter around some of it and in the hairpins the revs will drop to 1200 but it will still spin the wheels at this rpm.
at qr i use 3rd. i want to try 4th around turn 2 next time i go out tho. i may also drop back to second coming into turn 5-6 but only briefly.
please, please, please do not use 1st gear around archy everyone...
