^ No IS has a full size spare. You can see in that picture [post 10], the bar is supposed to bend like that...

 

Now, the sway bars don't/can't improve "handling" in the sense of "I can now negotiate this turn x miles per hour faster than before I had sway bars on" because handling at the limit is mostly a function of your tires, correct?

If you have wider tires, for example, I'd imagine your handling would improve because you now have greater surface area touching the road and therefore a larger centrifugal force is necessary for loss of traction (manifesting itself as a larger speed while negotiating the turn)

Someone who knows what they are talking about chime in, this is all mostly intuition.

 

See in the description when it says sway bars increase "precision"...that I can buy, that I get. Decreasing body roll will give you a greater sense of precision indeed, but it's not going to increase handling at the limit (i.e. you won't be able to negotiate a turn faster with sway bars on than without) because that is still a function of opposing forces (frictional force from tire touching road and centrifugal force)

 

okay sweet. I'mma throw this f-sport bar on hopefully tomorrow. WEeeEE

 

Incorrect.

It increases handling because it helps resist the transfer of weight away from the wheel(s)

Ahh I see, cool. That makes sense.

 

It's official... I F'd up my rear... sways that is. I'll let you know they perform tomorrow.

 

Do the sway bars first. Handeling and braking then prfomance and cosmetics. Thats just my opinion.
