If you're just going for ridiculously over-stiff suspension, why don't you just replace your shocks with solid metal rods? That should be stiff, right?
No I want a huge sway bar that I can adjust and soft springs on shocks that are correctly valved. I want the sway bar to control anti-rol and I want my shocks to control the up and down movements of the suspension per corner. That way the car is nice to drive on the street and very controlled in the corners.
You do know that by changing where the endlinks mount to the bar I can change how stiff the bar is, which effects the anti-roll way more than the actual size of the bar itself? (or changing the length of the arm conecting the bar to the endlinks) Bar size isnt the biggest factor in how stiff it is not by a long shot, a bigger bar just means its going to twist less when the load is transfered from one control arm to the other (which does make it more stiff) but isnt as effective as changing where the endlink mounting point is.
Like for instance my 30mil progress bar on the lowest setting is said to be rated at only 20% more stiff than stock while on the highest setting its somewhere over 80%.
