Looking good there Dan, what made you go for the 4.7 diff ?

Hey Moray
I’d had a original S80 4.7FD box in my first EK9 and what a difference it made so it was high on my list when I got this car.
took a while for a fresh one to come up so when it did I jumped at it. This box has the added bonus of the EK9 S4C forth and fifth gear so it’s actually and upgrade on a standard S80

I think out of everything that’s changed on my car this mod has made the most difference

I have heard that before about gearbox ratios. What sort of revs you doing at 70 in 5th.

I did the same put teg fd with teg 1st/3rd i think it was, along with mfactory lightened flywheel did make a lot of difference... Good mod without making the ratios too extreme for road/track use

Thanks, that would be great.
4350rpm @70mph in 5th gear... this is with 205/50/16 tyres

That’s exactly my thoughts mate, I think a 4.9FD or/and a close ratio kit would be slight overkill for a street driven motor

Yeah I think I also had an ac stage 1 clutch but can't find my build thread to confirm it... Was a long time ago now
