Torsion bars for stock suspension rebuild
Gee Greg!
That page is contradictory. It states increasing front roll stiffness will increase understeer or it will decrease understeer, see the quote from the page.
"Front roll resistance increases, increasing understeer or decreasing oversteer. May also reduce camber change, allowing better tire contact patch compliance with the road surface, reducing understeer."
My experience has been putting a sway bar on a car that doesn't have one is that will decrease understeer likely for the reason in the second sentance of the quote.
