RS400PRO

Four Wheel/Dual Laser Wheel Measurement System

Our most popular wheel measurement system for 10 years!  The RS400PRO is a four wheel, dual laser fully dynamic wheel measurement system.  With this system you can measure all four wheel locations both statically and dynamically.  No tape measures, framing squares, plumb bobs or string required.

 

How it Works:

1. Install the four wheel fixtures (Axle Alignment Fixture and Wheel T).  Front axle alignment fixtures thread onto the spindle.  Rear axle alignment fixtures mount to the hub drive flange, to the spindle or to the hub.  (Drive flange is the quickest, as the axle does not need to be removed.)  Wheel "T's" slide onto the axle alignment fixture and clamp down.  

 

2.   Install the two frame squares on the right (or left, your choice) side frame rail.  These fixtures are either magnetic or clamp-on.  

 

3. Install the laser stand on the chassis.  The laser stand clamps to the rear of the chassis, typically on the round tube fuel cell protection bar, a bumper bar or directly onto the rear clip behind the fuel cell.  Square and round tube mounts available.

 

4. Align the right side laser with the same marks on each frame square.  The laser adjusts with a thumb screw and moves inside the laser assembly.  Each laser projects a "laser wall" down the side of the car, creasting a line across each of the fixtures.  Next, place one of the 96" lay-out rulers on the floor in front of the rear tires, with the right side laser hitting the 1" mark.  Place the second lay-out ruler in front of the front tires. Now, adjust the left side laser to hit the same two marks on the lay-out rulers.

 

That's it.  Now you have two laser lines, parallel with each other and square with the chassis.  Walk around the car and instantly read toe and lateral wheel location on all four wheel fixtures.  Use a digital level and quickly measure camber.  Use a tape measure and quickly measure wheel base.  Turn the wheels and quicly measure Ackermann. Motion the chassis and quickly measure bump steer and rear steer.  Make an adjustment such as a trailing arm, panhard bar or tie rod sleeve and instantly see the result.

 

What it includes:

(4) Axle Alignment Fixtures, (4) Wheel Measurement Fixtures, (4) Collar Locks (2) Frame Squares, (1) RS-2 Dual Laser Stand Assembly with Chassis Attachment Kit, (2) Adjustable Laser Assemblies, (1) Caster Camber Gauge Adapter, (2) Billet Wall Mounts for Storing System Fixtures, (1) Instruction Manual, (1) Tool Set, (1) USB Drive with Real Square Set-Up Sheet and Calculator Program

Optional Accessories: Extended Right Side Frame Squares for Straight Rail Chassis, Center Line Laser, Left Side Frame Squares, Digital Toe Caliper

 

What it Measures:

Static* Measurements: Front Toe**, Front Camber***, Front Caster***, Ackermann, Rear End Housing Toe, Rear End Housing Camber***, Rear End Housing Squareness****, Lateral Rear End Location, Contact Patch Alignment, Wheel Base

Dynamic* Measurements: Front Bump Steer, Front Treadwidth Change, Front Camber, Front Caster, Ackermann, Rear Steer, Lateral Rear End Movement, Contct Patch Alignment

*Static = Car Sitting at Ride Height (In the shop/pits, etc.)  

*Dynamic = Car at Track Ride Height (Suspension Compressed or Extended as it is on the Track)

**Real Square Systems measure individual wheel toe, referenced back to the chasis, as wheel as total toe.

***Camber and Caster Requires Digital Level and/or Caster Camber Gauge.  CC Gauge Adapter is included with System.

****Rear End Housing Squareness is the position of the rear end, front to rear in relation to the chassis.  Also known as static rear steer.

RS200PRO

Two Wheel/Dual Laser Wheel Measurement System

This system is identical to our RS400PRO, with only 2 sets of wheel fixtures.  The wheel fixtures can be moved around the car to measure all four wheel postions. 

 

How it Works:

Identical procedure to the RS400PRO.  Instead of installing four wheel fixtures, install two, take the needed mesurements and then move fixtures to the other wheels.

 

What it includes:

(2) Axle Alignment Fixtures, (2) Wheel Measurement Fixtures, (2) Collar Locks (2) Frame Squares, (1) RS-2 Dual Laser Stand Assembly with Chassis Attachment Kit, (2) Adjustable Laser Assemblies, (1) Caster Camber Gauge Adapter, (2) Billet Wall Mounts for Storing System Fixtures, (1) Instruction Manual, (1) Tool Set, (1) USB Drive with Real Square Set-Up Sheet and Calculator Program

Optional Accessories: Extended Right Side Frame Squares for Straight Rail Chassis, Center Line Laser, Left Side Frame Squares, Digital Toe Caliper

 

What it Measures:

Static* Measurements: Front Toe**, Front Camber***, Front Caster***, Ackermann, Rear End Housing Toe, Rear End Housing Camber***, Rear End Housing Squareness****, Lateral Rear End Location, Contact Patch Alignment, Wheel Base

Dynamic* Measurements: Front Bump Steer, Front Treadwidth Change, Front Camber, Front Caster, Ackermann, Rear Steer, Lateral Rear End Movement, Contct Patch Alignment

*Static = Car Sitting at Ride Height (In the shop/pits, etc.)  

*Dynamic = Car at Track Ride Height (Suspension Compressed or Extended as it is on the Track)

**Real Square Systems measure individual wheel toe, referenced back to the chasis, as wheel as total toe.

***Camber and Caster Requires Digital Level and/or Caster Camber Gauge.  CC Gauge Adapter is included with System.

****Rear End Housing Squareness is the position of the rear end, front to rear in relation to the chassis.  Also known as static rear steer.

RS200

Two Wheel/Single Laser Wheel Measurement System

The RS200 is our newest system.  It combines the ability to measure each wheel individually, both statically and dynamically with two wheel fixtures, one adjustable laser and a simple, single sided laser stand that can be moved from right to left.  The RS200 can be expanded with a two wheel add on kit and measure all four wheels at once.   The RS200 was designed to be a high quality, fully dynamic, lower cost system.

 

How it Works:

1. Install the two wheel fixtures on the right side(Axle Alignment Fixture and Wheel T).  Front axle alignment fixtures thread onto the spindle.  Rear axle alignment fixtures mount to the hub drive flange, to the spindle or to the hub.  (Drive flange is the quickest, as the axle does not need to be removed.)  Wheel "T's" slide onto the axle alignment fixture and clamp down.  

 

2.   Install the two frame squares on the right side frame rail.  These fixtures are either magnetic or clamp-on.  

 

3. Install the laser stand on the chassis.  The laser stand clamps to the side of the rear clip, behind the rear tire.  Mounts for 2"x3", 2"x2" & Round Tube are available.

 

4. Align the right side laser with the same marks on each frame square.  The laser adjusts with a thumb screw and moves inside the laser assembly.  The laser projects a "laser wall" down the side of the car, creasting a line across each of the fixtures.  

 

You can now read and adjust the right side wheel locations.

 

For the Left Side, you have 2 Options:

 

Option 1. Move the Right Rear wheel fixtures to the Left Front.  Use a tape measure from the right front wheel fixture to the left front to measure toe.  Move both fixtures to the rear wheels to measure rear end housing toe.

 

Option 2. Use tape to mark the floor where the right side laser hits in front of the rear tires and in front of the front tires.  Move the laser stand and wheel fixtures to the left side.  Use two tape measures or lay-out rulers to measure from the RS laser marks on the floor to the left .  Adjust the left side laser to hit the same measurements on both tape measures.  Now the left side laser is parallel to the right side frame rail.  Read left side wheel measurements.
