or have any experience with this product from summitracing.com PN# Heidts RM-023 - Heidts Chassis Stiffeners?

 

That is just the center piece that bolts in to there subframe connectors it won't work with out them.If your looking at subframe connectors http://www.tinmanfabrication.com/ind...prod&prd58.htm are the best looking to me,Once you weld them in they follow the floor pan so it looks factory to those who don't know.And they have a driveshaft loop add on too.

 

my bad, I thought it was a bolt on subframe connector.

Thanks,
