Hi Mister Towed,
Hope you don't mind me asking a question. I've read earlier in your thread that you have changed your differential and that you are currently using 3:27 ratio one (I am not sure if you have an overdrive gear box or not), and that you are very happy with it. My question is; which differential would be better in your opinion, 3:89 or 3:63 ratio, with a Spitfire 1500 engine and non overdrive, 4 speed gearbox?
Many thanks, Deni.
