I don't want something I have to grease or worry about squeaking. The car may see a couple trips down the quarter mile for fun, but that's about it... I want an improvement over the current setup, but don't want the maintenance of having to grease the fittings. Does that help narrow down which one I should choose?
I have had the J&M street version on my '11 V6 for about a year now and it is my DD. The control arms are quiet and eliminated my wheel hop. I used the supplied grease for the bushings and I haven't reapplied any since and they don't squeak.
