I'm in the process of installing pretty much the same set of mods. At first I was really high on the CHE stuff. I've been told that it is all good quality. However....they do not offer Chrom-moly (lighter, stronger), so I switched. Going with a combination of Spohn and Steeda.

That is good to know as I don't know which metal is lighter. I don't want to any more extra weight to this car if I don't have too!

I was a little wary of getting all heavy duty stuff as the name somewhat implies the parts will be heavier to withstand all the abuse of competition racing, which I won't be doing. CHE is also a little more expensive than Steeda which is a surprise as Steeda usually has the highest priced stuff.
