Hey guys! Thinking about converting my Aristo to manual with an r154 box. My goal is around 500whp so single plates are a no go (don't want the ones with beefier pressure plates as I'm paranoid about crank walk). Found a gearbox + os giken 3 plate clutch + flywheel set for a good price, but not sure on how much life is left in the clutch. One plate is 3.82mm, one is 3.86mm and one is 3.92mm. Also looks like quite much hot spots. Read somewhere that OS Giken reccommends changing at around 3.5mm, is this true? Here's a link to the gearbox so you can see some pics: https://www.finn.no/bap/forsale/ad.html?finnkode=151276717
If it's very cheap...but that clutch does need rebuilt. That said, as you'd be not even remotely close to the holding ability of the triple....it should still work ok. But it does look like it has had a very hard life whoever was trying to drive it
