This is how the original fit of the part is. This is not a problem with the GKTech part, the OEM subframe has a lot of variation and GKTech has to have enough tolerance to be able to fit all of the subframes. We found this issue when we were modding subframes on our Formula Drift cars for Quick Change rear ends. Our cad designed parts didn’t fit too well and had to be fitted to each subframe individually.
Zac used an angle grinder and bench grinder to fit the reinforcement to the subframes.
Zac also used the angle grinder to clean weld boogers off of the subframe that was interfering with the fit.
Ah, now the fit is a lot tighter!
