I did the BMR HD Subs, I noticed no difference in the ride or handling. There might be a difference if you launch the car hard all the time, however I noticed no real improvement. I noticed a big difference when I added the BMR Strut Brace, Panhard Bar and Brace, and their Lower A-arm brace.
ive also ordered the struct brace and and the lower a arm brace.from what ive been reading i think i will also order the pan rod brace. i doubt i will get the pan rod bar.
