i had a set on my car, they were the first set that were made and sent to me to test for deflex free of charge.

they were ok for a while but i found the insert bushes kept splitting.

after a while and sevral sets of new inserts one of the bolts sheared so i scrapped them.

i'd get vibratechnics if your planning over 200bhp.

if not, just get a set from ford for a drev
