How to Dial In Perfect Suspension Settings with the HUDY Droop and Upstop Gauge

Why Suspension Geometry Matters for RC Touring Cars
If you've ever wondered why your lap times plateau despite trying different springs or dampers, the answer often lies in your suspension geometry. Droop and upstop settings are critical measurements that determine how your 1/10 or 1/12 scale touring car handles through corners, over bumps, and during weight transfer.
Getting these measurements right isn't just about going faster—it's about having a predictable, consistent car that responds the same way every session. That's where precision setup tools become essential.
What the HUDY Droop and Upstop Gauge Does
The HUDY Droop and Upstop Gauge Setup Tool takes the guesswork out of measuring your touring car's suspension travel. This machined aluminum tool gives you accurate, repeatable readings for both droop (how far the suspension extends) and upstop (how far it compresses) settings.

Instead of fumbling with makeshift measuring methods or trying to eyeball settings, you get clear, accurate readings in seconds. This means you can track exactly what changes you make and correlate them to on-track performance.
Key Benefits for Racers
Repeatable Results: The precision machined construction ensures you get the same measurements every time, which is crucial when you're testing setup changes or returning to a proven baseline.
Durable Construction: Machined from aluminum with an anodized finish, this tool will last through countless setup sessions without losing accuracy or showing wear.
Multi-Class Compatibility: Works perfectly with both 1/10 and 1/12 scale touring cars, so one tool covers your entire fleet if you race multiple classes.
Pit-Bag Friendly: The compact design fits easily in your pit bag without taking up valuable space alongside your other setup tools.
How to Use a Droop and Upstop Gauge
Using the HUDY gauge is straightforward. Place your car on a flat setup station, position the gauge at the suspension point you're measuring, and read the measurement. You can quickly check all four corners of your car and record the settings in your setup sheet.
This speed and ease of use means you can check your settings before every run, ensuring nothing has shifted during transport or from a previous session's impact. When you're chasing tenths at a national event or fine-tuning for club racing, this consistency is everything.
Why Precision Setup Tools Matter
At the highest levels of RC touring car racing, the difference between podium and mid-pack often comes down to setup details. Having accurate measurements means you can:
- Track what changes actually improve your car's handling
- Return to proven setups with confidence
- Communicate setup information clearly with teammates
- Diagnose handling issues more effectively
The HUDY Droop and Upstop Gauge is one of those tools that seems simple until you use it—then you wonder how you ever set up cars without it.
Essential for Serious Racers
Whether you're building your first complete setup toolkit or upgrading from less precise measuring methods, this HUDY gauge delivers the accuracy and durability that serious racers demand. It's an investment in consistent performance that pays dividends every time you hit the track.
