Here is a direct replacement, exact bolt on, no modification *UPGRADE* designed and manufactured exclusively by Advanced Automotive Technologies (Patent pending), to replace your original Superformance Mk-III Upper Rear Suspension Mounts. This replacement mount addresses and solves all the concerns of the factory mount by;  (1) Utilizing all 4 holes instead of just two,  (2) Increasing the leverage strength resulting from the increased mounting hole spacing,  (3) Manufactured from thicker and stronger steel,  (4) Tighter clearances and closer hole tolerances,  (5) Improved strength hardware and bolts strengths,  (6) Proper fitting bolts remove the weaker thread portion from the shear area,  (7) Rigid, stronger, thicker side plates distribute more even pressure onto the thicker edges of frame tube rather than on the weaker middle which reduces frame crush and therefore increases torque retention of the bolts keeping the mount tighter with less pressure needed. The Difference in just the MASS of steel used in the upgrade mount is 45.6 ounces each compared to the stock bracket weighing in at only 24.4 ounces. This is almost double the mass not to mention the increased strength in the steel material and design! This is nt a just another "fix", it is the CURE.

This mount duplicates the original shock and suspension settings and shock mounting location will not change ride height or affect the rear end alignment. This mount is adjustable to be installed at the typical factory bottom position or moved up one notch into the higher position. This new Upgrade bracket is made on a jig to exacting tolerances and are hand made one at a time in order to produce this kind of quality and precision, and very time and labor intensive resulting in absolute perfection.

...see example below


Just prior to ordering upgraded R/T suspension mounts this owner stated that he drives his car very little, mostly on good roads, never on a track and he was sure his mounts were in good condition. Until, the mounts were actually closely inspected which revealed the mounts were already tilted upwards significantly and the bolts were already sheared nearly halfway through. Even though the mounts do appear to be "ok", you can see the reality of the condition with a 90 degree square placed on the mount and frame.
