Are they recomended? I readed about them in the tech articals and how "your power steering pump will thank you". Well I don't run on the track yet but I will when I finish the basic bolt on mods. I also saw the thread about running them with big stereos. Will it hurt to not use them or is better to use them? the reason I ask is I am fixing to come into some money and wanted to put some into my cars system. Really nice cd player and good speakers, no subs, and I don't want to f**k them up by running it on the track all the time. Same with my power steering. Also could I expect to see any gains? If so, how does it free up power? Thanks in advance, Thomas.
