Just loved this!
Wonder who's the quickest
A bit of a clunk had developed in my Supra diff, so I decided to finally get Bara Motorsport to check it out and rebuild it, along with a Weir Performance stage 1 MAXGRIP kit. On inspection, the usual backlash issues with Supra diffs had come to light on mine, but everything else was completely immaculate considering its age. Crush sleeve was replaced along with a couple of seals, but the bearings were spot on (which are about 250 a set )
The original breaking point sat at 40 lb/ft which isn't really good, but after fitting the new kit, its now a good 97 lb/ft. Shouldn't be able to make 1 wheel spin anytime soon There's various other kits available for the kit, but a little extreme for road/track use. More suitable for full on drifters who take the cheaper option of welding their diffs.
