Hi Lloyd, it had only taken me 17 years to get around to fixing the GTM! The (3.647:1) diff ratio will better suit the car for speed events compared to the original (3.210:1) ratio. Also reducing the tyre profile from 70 to 50 which will help the overall gearing.
Nicely made bit of kit. Looking forward to seeing the GTM back on the road and all the mods you've done. Did you record the fwd facing gear selector mod? Well done.
Yes, I have used these differentials in chain drive applications. However you need to machine a special sprocket mounting plate with the bearing spigot as you will not be using the crown wheel.
Nice work Doug, that diff assemble will do a great job for you my friend

Hi Niall, yes I have recorded the gearbox mods and this should be in my next video on assembling the gearbox.
@@DougsShed Thanks Doug, looking forward to that.
would this diff be suitable for a chain drive conversion what type of bhp will they take.
