Q:  What is the proper Front End Alignment?

A:  1/16” Toe In

Q:  How do I adjust the Slip Tube in the front of the chassis?

A:  With the driver sitting in the car, there should be a 1/4” clearance between the nose cut outs on the body and the stream-line bi-pod tubes on the chassis.  You can adjust this by tightening and loosening the 1/2-20 nut on the front of the slip tube in the nose of the chassis.  If you have a 2009 or newer chassis with a snubber it should be completely backed off while adjusting the slip tube.

Q:  How much air should be run in the front tires?

A:  The proper air pressure is 40-45 lbs.

Q:  On 2009 cars and newer, What is the proper Snubber adjustment?

A:  After the sllip tube adjustment, the snubber should be turned up so the body is barely resting on it.

Q:  What is the best way to pick up the front end of the car?

A:  The front of the car should only be lifted by the stream-line bi-pod tubes.  NEVER by the front wheels, picking the car up by the front wheels will bend or twist the wheels.

Q:  What should the brake fluid level be in the master cylinder?

A:  The level should be 1/8” below the fill hole, after the car has been sitting for a few minutes.

Q:  What is the correct way to install the dzus plates on the body?

A:  With the body buttoned on the chassis and the plates rotated in the direction you prefer, use a hand drill with a 1/8” drill bit, spot drill all of the holes.  Remove the body from the car, finish drilling through the holes and rivet on the plates.  Only use the rivets supplied by HSD or aluminum rivets with aluminum mandrils.  Have someone hold a body dolly or a block of steel against the head of each rivet and tap the inside of the rivet flat.

Q:  Should the axle bearings be lubricated?

A:  Yes, the bearings should be lubricated with Dupont Tri-flow or a similar spray lubricant.
