Carlin Motorsport uses digital inclinometers to ensure optimum performance

Bowers Group has supplied Carlin, a professional motor racing team, with several Wyler Clinotronic PLUS digital inclinometers. The inclinometers are used in the workshop, garage, and at the track, making them a key tool in the set up and maintenance of Carlin’s motorsport cars.

Based in Surrey, Carlin is one of the largest teams outside Formula 1, with race experience in a variety of championships including British F3, Porsche Supercup, World Series by Nissan, Formula Renault 3.5, A1GP, FIA Formula 3 European Championship, GP3 Series and GP2 Series. Some of today’s most successful drivers have passed through the doors of Carlin, with famous names including F1 drivers Sebastian Vettel, Daniel Ricciardo, Kevin Magnussen and Daniil Kvyat.

The Wyler Clinotronic PLUS is a robust shop-floor proof digital inclinometer with 4 machined faces, permitting the measurement of angles through 360o. The inclinometers are used in the workshop on a daily basis to set up surface tables. Here the inclinometer is used in its absolute function to check that the surface table is level before work on the car commences. It is then used on various parts of the vehicle whist the car is mounted on the surface table.

Several important criteria are measured using the inclinometer. Machined areas on the chassis are used as a reference point, where the inclinometer is set to its relative function in order to act as a guide for relative measurements. The relative function is also used to set the angles of the wings in relation to the chassis. The steering is checked; Carlin engineers set the inclinometer relative to the chassis and then place it on top of the steering wheel to set the angle to zero. The camber and caster of the wheels are also checked, ensuring the correct wheel alignment of the vehicles.

Carlin engineers use the inclinometer at the race track to establish a level patch for any adjustments and maintenance to vehicles as required. It is used in its absolute function to ensure that the patch is completely flat. If a car crashes, or if a driver is struggling with a set up issue and the car needs to be adjusted, the patch can be used as a level base to ensure all measurements are accurate.

Carlin also uses a Clinotronic inclinometer to set up scale versions of cars in their offsite wind tunnel, allowing engineers to measure the downforce and drag of the car in a controlled environment.
F3 Chief Mechanic Ian Grant said: “The Clinotronic is very versatile; we use it in a variety of ways both in the set up garage and out on the circuit. For such a small piece of kit it is actually very important.

“The WYLER is used a bit more on F3 vehicles than other teams. This is because a lot of the other teams have a fixed wing angle requirement, as well as various standard measurements that need to be met. F3, on the other hand, is a championship where we have the flexibility to make more of our own components. For example, we are allowed to set our own angles for the front wheel blanks and the rear wings. Over a race weekend, the inclinometer is used to check that these have remained at a consistent level.”
