I looked at the G Comp suspension on Speedway and for some reason it is no longer available. The Heidts system is $1K higher than the G Comp and the G Comp is $1K higher than the Checkered Flag system. The lower cost is really what concerned me. You usually get what you pay for. One thing I noticed, with both the G Comp and the Heidts systems it appears that they include motor mounts. The Checkered Flag system does not.
I'll take what you all have said and check further and report back.
Thanks
