..Hard to tell, really. If you go down on this "board" to my previous contribution on the swaybar subject, you'll read that I use a rear 'bar from a 1990 900 T16 in combination with the SAS front 'bar. It costed me a gearbox. Which I got for fixing a Saab. (that should make up for the ridicolous freight price on the front 'bar)
I therefore have not tried the SAS rear 'bar, and can only speak for this setup. BLOODY MARVELLOUS. That's what it is. I won't take those 'bars off for all the butter in Gothenburg!
Mind you, my car is a five-door combi coupe (wagonback, stateside) and the weight distribution is 58/42 as opposed to a two-door saloon with 62/38. (All numbers count, in chassis dynamics)
IN THE LAST ROUND OF "PRO'S AND CON'S FOR THE FRONT 'BAR"...
..there was a great deal of meanings and theories expressed.
The thing about Saabs, is that they're usually owned by individualists. Its hard to make a congregation of individualists to "walk in the same direction". Very hard.
I would, however, like to shed some light on the matter of anti roll bars. Take the "camber-theory", for instance. -The true story is that body roll ecceeds the negative camber induced by suspention compression, resulting in a POSITIVE camber, thus increasing ascew-roll-angle. The latter goes for both the inner and outer front wheel. Compression of the a-arm bushings must also be taken into consideration. The wheel flexes quite a lot around in it's housing. Kick the wheels and see for yourself.
Remember, camber is measured between the wheel and the ROAD, not the wheel and the car.
As a thumbrule, we say that a front bar results in understeer, and a rear bar results in oversteer. One may be mislead to believe that if both bars are fitted, the car will drift more sideways through bends. (Both front and rear wheel ascew-roll-angles increase)
This is NOT the case. The quoted under- and over-steering are relative terms and opposed to the opposite axle. Meaning, the car will grip more. The 900T16/SAS combination on my car actually eliminated the high-speed-understeer, very much present earlier.
The acclaimed "WHEELSPIN THEORY" does hold more water. Provided we talk about sharp u-shaped hairpins tacled in first or second gear, at full thrust. But going through sharpish bends at 80-120 km/h will NOT result in wheelspin. For two reasons;
-At those speeds a normal Saab engine does not have enough power to breake loose the front wheels.
-If one has a VERY powerful turbo engine WITH enough power to do so, one DOESN'T apply full throttle in the middle of the bend anyway. That will send you right into the hedges, swaybars or not.
Good luck.
Karl.
