Gauge set

When every tenth of a millimetre determines whether the car passes technical inspection, the T800 T870079 gauge set is the reference in the slot workshop.

The ride height is one of the most monitored parameters in any serious slot racing competition. A chassis that is too low scrapes the track and loses speed; too high, it compromises the centre of gravity and traction. This T800 set resolves the verification directly, repeatably, and without margin for error.

Features and Highlights

• Six stepped gauges: 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, and 1.0 mm cover the usual verification range in most club and championship regulations.
• High precision manufacturing: minimal tolerances that ensure reliable and repeatable readings with each use.
• Compatibility: suitable for 1/32 and 1/24 scales, the two most widespread formats in slot racing competitions.
• Compact design: easy to slide under critical points of the chassis —motor, bracket, body ends— without moving the car from the preparation bench.
• Reference: T870079.

Applications in the Workshop and Technical Verification

The most obvious use is the pre-check before a heat or competition day: each gauge is slid under the chassis to confirm that the car does not touch at any critical point. However, the utility goes beyond simple regulatory inspection.

During tuning, these gauges allow for progressively adjusting the height by modifying the length of the suspension screws, droop stops, or motor position, and immediately verifying the result. If you are working with flexible plastic or carbon chassis where deflection varies with load, having such fine stepped measurements —just 0.1 mm between steps— makes the difference between an intuitive adjustment and a documented one.

For technical scrutineers of a club, the set is equally practical: it allows for a unified verification criterion among all controllers and eliminates the subjectivity of the human eye.

Recommended Assembly and Use

• Place the car on a flat reference surface (glass or level bench).
• Slide the thinnest gauge (0.5 mm) under the point to be checked. If it fits loosely, move to the next measurement.
• The gauge that fits with slight resistance —without bending the chassis— indicates the actual ground clearance at that point.
• Repeat at all four ends of the chassis and under the motor to obtain a complete picture of the ride height.
• Clean the gauges after use to avoid the accumulation of carbon dust or tyre particles that may alter the reading.

Frequently Asked Questions

What scales is this gauge set suitable for?

The T870079 set is designed for 1/32 and 1/24 scales, which are the most common competition formats in both club circuits and federated championships.

What is the difference between using these gauges and measuring with a micrometre?

The micrometre measures static dimensions of a part; a ride height gauge measures the clearance between the chassis and the running surface with the car in racing position. They are complementary tools, not equivalent.

Does the set include any support or case?

The available information does not specify any additional case or support. Please check the product commercial sheet or contact us to confirm the exact contents of the packaging.

Can they be used to check the motor height as well as the chassis height?

Yes. The usual use includes checking the clearance under the motor (especially in inline configurations where the motor is very close to the track), as well as under the sides and ends of the chassis.

How often should I check the ground clearance of my car?

At a minimum, before each competition day and after any changes to the suspension, motor, or tyres. In a flexible chassis, the height can vary even with tyre wear.

The T800 T870079 ride height gauge set is a precision tool for slot car preparation and technical scrutineering. Including six stepped gauges from 0.5 mm to 1.0 mm, it covers the full range needed for 1/32 and 1/24 scale slot car inspection. Essential for any serious slot car workshop, this set allows repeatable chassis clearance measurement, helping racers optimise centre of gravity and comply with club or championship regulations. A reliable addition to any slot car tuning toolkit.
