Roadster Sport vs. Progress Sway

Postby awales74 » Mon May 07, 2018 11:08 am

Looking for differences between Roadster Sport and Progress Sway. Focusing on front bar and assuming the back is built to match. What is the range of strengths of the 3 different positions.

I can find numbers for the OEM bar (132 lbs) and Progress bar (429lbs to 591 lbs). From product description, one would expect Roadster Sport to fall within OEM and Progress. But does it range closer to OEM or stiffer towards Progress.

Feel free to just link me to the thread if it's been discussed. And correct my numbers if I'm off base.

Assuming ND/Fiat

Progress
Features:
-Size: FRONT 28.5 mm (hollow bar; 6.35mm side-wall)
-Size: REAR 17.5 mm SOLID

RoadsterSport

*Front Sway Bar: 27mm OD / 3.6mm wall, 3 adjustments
*Rear Sway Bar: 16mm solid, 3 adjustments
*Locating Collars
*Bushings and Brackets

YES....the RoadsterSport is about halfway in effective stiffness, our top choice for street enthusiasts. Progress Sways are a lot more serious on rate, more for those serious about weekends of track/autocross. Do you race? If you do, Progress. If you don't race, RoadsterSport.

Hi Brian,

What is the purpose of the locating collars? The stock sway nor the Progress sways have them. Also, does it matter whether they are installed inside or outside the brackets or at all?

Thanks,

Andrew

Both bars have something that limits bar sliding through the bushings too far to either side, on Progress it is welded on ring to prevent slide and on RoadsterSport crimp on collars doing the same job. The crimp on style can be either side that it fits, does the same job either way.

What is the usual or suggested distance the collar should be located from the bracket?

You want it close to do the job, let's say an eighth inch clearance.
