I fitted the new Delrin diffs outdrives to my car this weekend and they really look trick. The bearings are a really tight fit to get on though and there was a lot of choice language used. But on the track car was good .... can't say it was down to the diff though ...!
I am also using the associated diff thrust spring, and t-nut and bolt. Diff is super smooth and a bit lighter with the new delrin outdrives. If I had a super accurate scale I could tell by how much
Now I want to use my old parts to make a spool..... any advice??
