Coil Over vs Torsion Bar
Again, not at all trying to be argumentative or trying to convince anyone of anything. That said, you are comparing the Gerst to a another aftermarket system and in that vein it is apples to apples for the most part, however if you compare it to replacement/rebuild of the stock components it is quite a bit different. A quick look at a Gerst system in basic format with PS and 11" brakes for a A body with a SB is $5K, you could absolutely completely rebuild a stock front end using performance components for less, but is it as good? Thats for the owner to decide but the argument centers around this main point and those who favor stock components will argue it is and cite many examples (such as the green brick), but here again this is probably not a true apples to apples comparison as there are many factors involved ranging from the actual parts to drivers, tires, etc.
My point is merely this, if you want a CO suspension then you should have it, if you want stock type stuff, then go for that. I posted what I did more for the new person who really doesn't know what the want and is looking at the new and shiny as being the best and the stock type stuff being "not as good"; this is not truly the case is all I am saying. The real point here (IMO) is this, can you make a Mopar with stock "style" parts handle and brake as well as possible or do you need a whole new system? I would argue that you can, but that the new stuff absolutely works. In other words, you do not need to spend $5 - $10K to make the car work well. If you need or want the header clearance or have some other reason why a CO system is more beneficial (or just plain "want it"), then so be it, but you so not absolutely "need" it to make the car work well.
