So can anybody tell any good experience with the so called Detroit Rockers from brenspeed? Installation tips, performance wise, driveability and of course the sound? Do they really give a real nice rough idle sound?

 

I've got them on my '09 & I'm very happy with them. I had Brenspeed install them rather than trying myself. They do give a nice idle, with a little less lope than the FRPP Hotrod cams. They pull great from 3000 rpm on up, noticeably better than before. The car lost a little on the low end, but I had the Steeda delete plugs installed at the same time, & they may have been what hurt the low end. I've got 4.10 gears, & before the cams & plugs I could idle away from lights with ease. Now I have to give it a little gas. To me, it's a minor trade-off. Love the cams.

 

Well I think that wouldnt be any issue with an automatic but since they dont need anything else then the cams I think they would be worth it
