I've got a BGH built TranX type 9 5 speed SC - I love the noise it makes, and this racket suits a 7 when driven quickly. It's somewhat strange with the quiet 4th gear though, but this is great for cruising through town, and when Mr Plod is in attendance.
My 5th gear is 0.9 which suits my 2litre zetec car, but it's the 2.36 1st gear that makes the box special IMHO
Oh I have a 3.5 rear ratio Quaife ATB fitted too and can vouch for this setup over a 3.7 or 3.9
