I've installed the subframe connectors and they did stiffen up the frame substantially, though I have no way of giving any definitive answer as to how much.
Worth the money? Not sure. It could just be placebo effect, but when I installed the connectors, it
seemed to have eliminated some of the squeeks inherent in our chassis and also helped tighten up the handling characteristics....though there is no real way for me to prove either statement.
The one upside that I can prove....they are a great alternative to the normal jack points of the car
Had I not gotten a great deal on them from another CEG'er I probably would not have purchased these. At the price I received them for though, I can't complain.
