We have testing 3 types of front diff mounts on the s30 Z car and this is the best option. It is just as quiet as a rubber mount, but with zero flex! The differential will not move at all and your clunk noise will be completely eliminated. While driving on the freeway you will not hear any winding noises. it is quiet as a stock rubber mount.
Made in USA from t6061 aircraft grade aluminum. Comes with bolt and nut for mounting. This solid mount is for good for street and track use. it will keep the rear end in place and will not let it move and flex. This mount will eliminate the clunk sounds you get when accelerating or decelerating.
We also installed a Ron tyler stly mount that hold the diff from above. This mount still had some clunking sounds and flex on the first day. Lastly we tested a brand new rubber OEM front diff mount and it had even more clunk sounds and flex under accelation. Dont waist your time with these other types of mounts. Solid is the way to go.
