That's exactly right. I hope so or else a lot of us have been ice-skating up a hill for many years

I'm going to reopen this thread and throw the cat amongst the pigeons.

Here is a quote from Harry @ TPC Racing

Quote:

When you put a soft front sway bar in the front and a stiff sway bar in the rear, the car will handle poorly and want to spin. It can be dangerous. I have driven several cars set up like this and they are dangerous to drive. Any car you see on track has a stiffer front bar than rear. Our bars are race winning and proven bars and we have seen them decrease lap times by over 5 seconds per lap over stock.

Now, maybe I am behind with my reading but from the research I have done so far, I was under the impression that the rear had to be firmer than the front?? Unless of course, people are making presumptions that the hole positions are relative to the two bars having an identical base stiffness.... So maybe the "soft" setting on the front bar is actually much harder than the hardest setting on the rear.

Interestingly, Harry's information validates the figures posted by VividRacing!

I imagine, unless someone systematically compares front and rear bar combos from a couple of manufacturers, we may not know if the front bar is supposed to be softer or harder. So much "mystery" in the AM world!

I think even Harry would acknowledge that setup goes beyond just sway bars. I bet you I could set the same car he is talking about up to understeer like a pig. More weight in the back will require more stiffness to balance. I doubt the sways are equal to begin with. I have driven an undoubtedly stiffer h&r rear with stock front in AWD and RWD and felt nothing of the sort. Of course mine is 996.

Just my opinion though.
