max, q45tech suggests from his previous posts that with re: to 1994 q45 standard with 29 mm FSB: ......ifever installing a rear sway bar (20 mm) for a q45 standard you gonna have to downgrade the existing 29 mm FSB to 28 mm FSB (found in 1994 q45a / q45t) , since there are no existing 22mm RSB.
In the case of small diameter rear sway bars, the name is probably a misnomer since an EXTRA 40 pounds per inch of resistance tacked on to 123 lbs per inch SPRINGS is only 1/3 stiffer.Instead of a max of 4" of rear body roll the same G force would still roll the rear 3" with rigid bushings and 3.3" with rubber ones.What the factory does is change the existing front sway bar to a smaller size 29>28mm which increases the front sway by 13%/2 or 6.5% reducing the tire slip angle [load] on the front by roughly half that amount.The rear has less weight on the tires [they are not being overloaded like the front] so the rear bar increases the rear load by some amount and the smaller front bar decreases the front load.
The ideal situation is for all 4 tires to have the same load [weight pushing down adjusted for the differences in static weight distribution.
The Q unlike most cars has an agressive camber curve control which attempts to keep the tires [the tread part] perpendicular no matter how much the body rolls.With this taken care off by the upper links one can concentrate on balancing the load induced by turning [not really trying to minimize sway per se].
The front sway bar [is so big] to reduce the traction on the front tires making the Q progressively increase its understeer.
Wish there was another common name for sway bars which better described what we are trying to do!
