M030 Sway bar tuning
#1

I use my adjustable M030 sway bar to tune the under/over steer of my car quite a bit. I'm at a point now that I really would like half a bolt adjustment. One comment brought up previously was to stagger the left / right holes (left hole 1 and right hole 2). This would require adjustable end links to even the pre-load, but I question if you would end up with equal handling in both directions or do you end up loose on one side and tight on the other. That would be my thought as the lever arm is longer on one side than the other.



Other thoughts:

- Add the KLA adjustable drop links. Although these will get rid of the rubber slop, will they increase the effective stiffness of the bar. Seems that it would only make the bars action more precise, not stiffen it once loaded.

- Add the delrine bushing. Same comment as above.

- Drill out the metal between the holes, creating an infinitely adjustable slot. This may be the best idea.

- Dump the M030 rear bar and get a full race bar like the one sold by Paragon. $$$

I a fan of both the adjustable droplinks and the Racers Edge delrin bushing and block set up. I sell both and use both,. They are on my list of favorite suspension upgrades for this car. I truly hate rubber bushings on swaybars. It's almost silly they have them. When you take a corner hard the first several milimeters of swaybar movement is deflection and not actually transfering load across the bar to keep the car level. the other problem with them is the rubber drags on the bar preventing rapid changes in swaybar load. it reacts very slowly.

The rear droplinks are very important to set the bar at zero preload when the car is on the ground and even with driver weight in the car. this way the bar reacts the same way on left and right turns..

You will find if you do both of these at the same time the rear will keep the power down much better and you won't have an imbalance between understeer and oversteer.

When I had my Rothmans Turbo cup car this was the best suspension change I played with. I had reduced throttle oversteer and if I had any understeer it was track or tire conditions. I never needed to change bar again. if i had a handling "condition" I was confident the car would be perfect again when Tire temp came up or track temp would come up or track just needed more rubber on it. I knew it wasn't the car

I just changed the rubber bushings on my M030 anti-sway bars to the Delrin bushings from Racers Edge. I will have my first track event with them on sunday and let you know how it feels and the difference in time (if any). Bob Blackwell.

ps, you can cause changes by altering the tire pressures too. Good luck, Bob Blackwell.

i too have the racer's edge delrin rear bushings and kla droplinks - i had to make a modification to the rear bushings, to correct a small design deficiency, but they are working well



i have used similar bushings in other cars, and they make a big difference
