Question about the diff between the diffs...(couldn't resist).
I'm doing a lot of highway driving lately, the low cruising speed and the high rpm is getting to me. I'm thinking of solutions. 5 speed - expensive. Overdrive - expensive for nice, still expensive for worn out.
I've got a shockingly nice running 4-speed in my Spitfire that is almost feels like new in every way. I can't stomach taking out and replacing with an overdrive tranny that might have all sorts of unforseen problems.
So, I am thinking about putting a GT6 diff in its place which I hear is 3.27:1 ratio versus the stock 3.89:1 ratio Spitfire diff.
Firstly, does anyone know if mechanically there is anything stopping me from doing this? Such as the leaf spring not fitting, or the drive shaft not bolting up right? Axle flanges?
Secondly, a question about the ratios. I think it would go quite nicely considering the way it is now you can almost pull away from a stop in second its so low geared!
Any input would be greatly appreciated.
Adam.
