Features:
Torque Solution Polyurethane bushings are much harder compared to the OEM units. By replacing them with these harder Polyurethane units you are able to get rid of the unwanted slop and flexing of the stock units which allows for the power to go into rotating the tires, instead of flexing the rubber. Giving you better feedback, sharper response, more predictability on throttle input, along with eliminating annoying clunking during hard shifts.

Def one of the easiest upgrades I ever installed. You will need a jack for reinstalling the cross mount after adding the inserts to the bushing.
Installed at the same time as a group n transmission mount, you can honestly feel a difference when driving. Highly recommend. Cheap $$ too!
Works well and makes a good difference. Would highly recommend
Great product and always enjoy ordering parts from you guys. Love the crisper shifts
Great quality, but makes a decent difference. Easy install as well
These inserts remove a good amount of slop. On throttle, the feedback has improved. Install wasn't difficult on jack stands, but it will be much easier on a lift. I used one insert on the carrier because it would have been very difficult to reinstall the carrier with both installed.
So I’ve already done the STI JDM pitch stop, trans mount and shifter bushings but the inserts at made a subtle but noticeable difference. Biggest difference I felt was slightly less surge of the drivetrain when you don’t nail your up or down shift plus better shift feel under hard acceleration. I noticed no additional NVH with these inserts. Highly recommend
So it is hard to say how this made a difference when I have the Perrin pitch mount and installed the group n trans mount, but just like the videos on IIR’s YouTube, all these components combined gives you a great solid feel in the vehicle with no play or movement through shifts.
Now what was difficult was getting the last bushing on the bottom diff as it was too long and we actually had to cut down a portion of it so that it would fit flush, but other than that easy install.
This was such an easy mod to do at home. It adds a subtle improvement alone, but with other suspension upgrades…the car feels much better.
Makes downshifts smoother and high rpm shifting doesn't jerk.
