drs silencer aa/fc questions?

i'm building my first drs silencer using a open koford motor.  two things i'm not sure about with this chassis kit is should i mount using the front mount or through axle. 2nd how is the rear mount suppose to be setup as it describes a brace tube. Last i'm debating whether to use .72 mains or .82 mains? any input...thanks

I myself would use a floating front mount. The rear mount would prolly be something like whats in this pic.  .082 mains.

Re: drs silencer aa/fc questions?

Putting the front body mount at the front axle in the conventional location is alot more forgiving than using the other mounts. The choice of which tubing to use depends on what kind of power you have. If you are running an older quad setup with a 64 or 54 arm in it, .072 works well. However, if you are using a 6 mag billets setup with a 43 wind arm, the .082 will work better.

Only problem i have with the front axle, and that use to be the way I use to do them, is it allows the nose of the car to dip down at high speeds.  So to compensate you have to run the nose a little high and loosing some aerodynamics.  Mount up in the nose and you can get it down lower to the track!

Are you cutting your guidepost off? If the nose of the car is dragging, it is either mounted too far forward, or it's not supported enough.

my 2 cents, use the mount up front, you shouldn't have to trim the guide post.  the backend use the upper support bar as a brace, the the back holes for the floating mount.
