This is what I've been hearing about the BMR inserts.

I must have been snoozing. What's the issue with Pedder's?

Bought Energy Suspension bushings and returned them due to obvious low quality. Installed Pedders inserts and I am very satisfied with the results. Stock the car would get a "oh Sh*t" loose feeling when pushing the car to 8 tenths on high speed corners. The Pedders inserts keep everything firmly planted.

This is why I went with BMR full bushings. 580+ at the wheels I would have just been throwing time and money away with anything less.

Inserts don't seem to hold up well, especially on the higher H.P. cars that are tracked or driven very aggressively on the street. I stopped installing them after seeing them being squeezed out from hard use.
If you are considering it go for the full bushing replacement, its worth the extra money.
