Any negatives to running BMR sways on "stiffest" setting on the street?
I'm having BMR springs and sways installed on Monday, and the way I see it, since I'm paying for aftermarket suspension upgrades, I might as well use the "stiffest" sway bar setting. Is anyone running this "stiff" setting on the street? Any issues? I want the handling to improve as much as possible, but I also understand that TOO tight of a back end will start to hurt handling. Thanks for any advice!
EDIT: I'm mainly looking to help (hopefully eliminate) the understeer, it drives me nuts, and will be doing autocross events every few months if this helps.

I'm not a suspension expert but sway bars do not change the ride quality of the car. Sways reduce the amount of body roll in turns. The ride quality will change from the springs.
Having your sways on the most aggressive setting will increase the chances of oversteer in turns (which is more desireable than understeer). When you're at the autocross, you'll have to use the throttle to help steer the car correctly.

They only time they effect ride quality in a negative way is when a bump is hit on one side of the car that is unequal to the other side of the car. Being on a stiffer bar/setting will intensify this. As far as cruising down the road on a flat surface, you would never notice a difference until you turn or like I said hit a bump on one side.

The biggest issue I have with my upgraded sways and endlinks is tripoding when going over an uneven surface.

I do believe you that too rigid of a front sway will cause understeer, but I'm having trouble understanding why? Can you please explain that a little bit? Thanks again

Basically, a sway bar's job is to use the weight of the other side of the vehicle to put torsion on the sway bar and lift the outside of the car to prevent it from "dipping down" or "rolling over" (body roll). When you have body roll, the tires on the outside of the turn get pushed down toward the road and the tires on the inside of the turn rise up. When the sway bars are stiffened equally, there will not be a change in oversteer/understeer, only significantly less body roll. Now say you have a stiff rear bar and a soft front bar. This allow's the weight to transfer to the front outside tire and will reduce the weight on the rear inside tire in the turn. This gives you more front end grip and less rear grip and allows the vehicle to rotate around the turn. This is often referred to as "lift oversteer". Lift over steer in a RWD is not necessarily a good thing as you can usually make up for a little understeer it with a throttle steering. If you have too much oversteer, you are just going to spin out. The ultimate goal is to find a neutral balance so that when you are on the edge of traction in a turn, all tires will begin to let go evenly and not more so on the front (understeer) or the rear (oversteer). I hope this helps and if you have any more questions feel free to call, PM or email me. Best regards, Tyler 888-308-6007 |

Too tight in the rear makes the car extremely prone to snap oversteer (especially if the front is soft). Full hard (1000%+ harder then stock) is most useful on R-comps, you won't ever see the traction levels with street tires to take advantage of it.

Later I went to the max setting and the car was dead neutral. But it was a little too easy to go into oversteer, so you had to be very careful. Maybe not snap, but it did make the adrenaline flow a few times. Later I was told that when you use the rear bar to overcome staggered tires, this is the effect you will see. So I would start with the middle setting and get used to that first. It is easy to bump it up later if you want to try it.

I was just saying it made the transition a bit touchy. IMO it's a good idea to get used to neutral slowly.
