gearbox

I used a BWCR 12 when I raced an Arnolt Bristol. First was gear to start the car in motion only. I used the ring and pinion from a BMW 328 to help acceleration. Final ratio was 4.2 and good for 110 to 120 mph. If you are racing you must use ATF in the transmission, the transmission overheats and you will lose your synchros if you don't.
