I guess not bad for a scale meant to weigh tractor trailers.

Called QA1 twice for their thoughts and called the selling vender, and came up with 450 lb. spring rate. They work just fine. I think the 55 will weigh a bit more than the 47-54.

I too have a Camaro clip on the 54, and they are a bit wide for the 47-54. I cut an inch out of the top and bottom a frames. Later I found out about the race arms from speedway. I wish I would of known before I narrowed the tops. They work fine just not that easy to do.

Didn’t know about the G-body frames. Sounds like you’re on the right track.
Good luck Shawn

450 lbs springs, is the ride stiff?
