chevelle splined sway bar rates

[The WidowMaker]

yep, that makes sense, or so i think. if im understanding, you moved the pillow blocks slightly inboard, put a collar to the outside of those but still under the frame, and then put the arms on the outside of the frame, but just barely?

at first i thought you were placing the arms under the frame and i didnt see how that would fit. but if youre leaving about 1/4 - 1/2 on each outboard side for clearance and then putting on the arm, i dont see why i would need 3" for a 39" total either.

im going to give speedway a call and see if they can tell me some more "can" and "cannot" dos.

but until then, anybody know if i can put the pillow blocks on the furthest outboard side of the bar? id run a pillow, collar, arm, arm, collar, pillow and call it good????? the pillows would be on the splined portion, but i dont know if that would matter all that much.

thanks, Tim

That's right.

My blocks are not on the splined part of the bar.

playing around with performance trends, it says ill have moderate oversteer with the 500 front and 300 rear. i can either go down on the rear or up on the front with bars, or drop the roll center a bunch more. i really dont want to much bar rate in the front since it will be a driver and there will be pot holes, driveways and the such, but i really dont want to hurt the handling by putting something too small on. the good news is that bars are only $130, so although it sucks, it aint "that" bad to do some testing.

just an update..... i installed the rear bar. i got an 1.25" bar thats turned down to 1.00" in the middle. i found out some interesting stuff along the way though.

first is that the 37.5" bar is actually 37.75".

second, the arms can ONLY be mounted in one place. there are two bolts that hold the arms on the bar, and the splines are cut down in only one area to allow the bolts to slide through. i thought that i would be able to position them slightly, but this position leaves about 3/16" to the outside of each arm.

third, with the arm, pillow block and collar all squeezed together as much as possible, the collar is resting on the area that steps down to the 1" portion. i think it will work, but im going to drill a slight hole for the set screw so theres no chance of it moving. im not sure though why there wouldnt be enough room and since the front bar steps up, i dont know how its going to work.

lastly, i dont believe a 37.5" bar will fit on the front. btwn the 3/16" per side, plus the arms, plus clearance to the frame, i think its going to be too tight. maybe a 38, but i think a 38.5 safely.

ill post pics of the rear bar in a few weeks.
