In Reply to: Adjustable Sway Bar Question. posted by TCD on January 08, 2001 at 21:32:00:

I am preparing to install a set of used sway bars 22/16 on my 535is. Which of the three holes will likely work the best. I will be using the car as a daily driver and for driving schools. Only other suspension mod is a set of RD springs and a set of 225/50/15 R1s for the track.

Jim's suggestion is a good one.HOWEVER,running a 535is with stock brakes added to stiffer swaybars,and the R1's,there's a 50% chance of warping the rotors before driver's school is finished. Ask me how I know...

1. try to add ducting to the brakes from the small oval opening below the foglites,& remove the front backing plates for cooling. or...
2.gas-slot the rotors or use cross-drilled,adding a track pad compound. or...
3.upgrade to the 7 series front brakes.

Then,you will probably want to weld tabs to reinforce the center brackets for the swaybars.BMW left a bolt on one side,but only a tab on the other,which often pulls right out,just in the middle of school. HAH! Ask me how I know that one too.
And make sure the 15" wheels you use have a design that allows ALOT of airflow.Old 750 rims,or the 20-spoke "bottle cap" rims,don't cool well enough at a long track if you drive hard,unless you add one of the precautions I mentioned above.
Now you can enjoy the driver's school weekend.
