has anyone use js racing solid diff mounts on a turbo ap2? i wonder what it will feel like and will it help the diff out?

 

Those have been discontinued. Perhaps there were problems to the differential eventually but I'm not sure. I'm not running on FI but I've installed a set of differential collars to my S2000 and is a great improvement. Have a read below, you might find those as a good alternative for your setup.

I look it up looks good to me and cheap

 

Had them for awhile, SC owner here. Another buddy also had them for awhile, NA owner. Definitely a proper upgrade and a very well made product (proper full solid 1-piece perfectly machined), pretty much the same deal as upgrading to Innovative engine/transmission mounts.

No adverse effects of noise or anything unusual. In fact, they do aid putting the power down more effectively, reducing drivetrain loss. The OEM mounts are way too soft in comparison. Inserts might work, but I'll definitely try and hunt down a set of these. Glad to have got em before they got discontinued, very worthy upgrade.
