I have a feeling either my block was mis machined or the car was built incorrectly. BMR mounts wouldnt bolt up correctly (holes were off about 1/2") so I purchased some stainless steel plate and fabricated my own plates that bolt to the cradle. LET ME BE CLEAR HERE: I do NOT believe this was something related to BMR.

When I bought the car brand new, ordered from a dealership owned by my family, it wouldnt align correctly and would pull hard to the left when I floored it. Only after buying BMR on car adjustable everything for the rear was the car able to be aligned correctly. The shop that did the alignment said there wasnt enough adjustment to bring it into spec with the stock parts.

At any rate, I absolutely LOVE these mounts! They shed a fair amount of weight and on a ZL1-1LE, you barely notice any additional harshness. The only caveat IMO, is if GM built you a Monday or Friday car, you might have issues. My car was built right after the 2019 strike ended BTW.
