Rear anti-sway bar for type 85

[Alan Kramer]

Talking about rear sway bars made me remember I never posted this info to 
the list:

I've found that a CGT front sway bar with the Z shaped link pins works 
*extremely* well when mounted upside down on the axle beam of a CGT.

I used to run an addco rear bar, and found it contacted the panhard bar when 
there was enough body lean, causing the inside wheel on left (or was it 
right, can't remember) turns to lift prematurely.

Anyway, to do this: Mount the front sway bar to the bottom of the axle beams 
using summit racing 1" swaybar bushings (part number  ENS-9-5110G).  You'll 
need to put a flat piece of steel with two holes in it identical to the 
holes in the steel piece of the above mentioned bushing on the bottom of the 
axle beam to support the bushing.  Mount these (bushing and flat piece) to 
the axle beam using muffler clamps looped over the beam with the bushing 
hanging off the bottom.  Fabricate two mounts for the chassis using 1/4" 
steel plate about 1" wide.  They will be shaped something like this:

       /
   /|_|

Sorry, but easier to draw than describe.  Drill 2 holes in the slanted 
pieces, and a hole in the flat piece on the bottom.  Your link pin goes in 
the hole in the flat piece on the bottom.  Bend two U shaped pieces of very 
long bolts w/o heads (or weld three bolts together w/o heads like I did) so 
that each leg of the U goes through the holes in the slanted pieces of the 
above made brackets.   Use the brackets to find where you need to drill 
holes in the frame, and drill your two holes per side.  Connect up the 
bracket, and fish the U shaped bolt you made through one hole and out the 
other.   Use Summit Racing end link bushings  ENS-9-8105G  to connect the 
link pin to the bracket you made.

Anyway, the cool part about using the front sway bar is that when it's 
mounted upside down, the curves allow the panhard rod to clear when the body 
leans.   Additonally, it's a few MM thicker than the addco bar.

I'll caution everyone that my experiences in auto-x with the 4kq front bar 
and CGT front bar on the back, the car does have a *significant* oversteer 
tendency if you do something stupid like hit the brakes in a curve.   I I 
have set the car into 4 wheel drifts by popping momentarily off the 
throttle, but have always needed to brake to spin it completely.  On the 
street it's well balanced in most situations, but again will oversteer in 
some extreme cases.

I guess I could take pictures if anyone's interested.
