Hi guys, just posting up on our rear diff bushing solution which is 2 part.
The pinion mount has a 3-p design which has a large amount of stability at the collar with the 100 durometer insert and a small amount of give with the 90 duro upper cushion. Finally a 70 duro sqush collar applies final pressure on the complete stack and takes up the gap on the factory washer.
I did a quick tutorial on the pinion mount for our IS-F which uses the same style pinion mount.
here it what it looks like installed.
The rear diff mounts are face centered and we have an adapter kit to use with our center mount bushings that includes longer bolts and 6 stainless steel spacers. The combination of both mounts should net a very stable rear diff but still allows some shock absorption for hard shifts and initial power application.
I will add more pics of the rear install shortly. but it looks like this installed.
As with all of our bushings they are manufactured by SuperPro Australia for us and carry a lifetime warranty regardless of use.
