SARD tuning for performance and street cars


Founded in 1972, SARD started racing in the Fuji GC series and in 1973 SARD entered the Le Man 24 hours with the Sigma MC73.

Since the "70s SARD continues to be involved with racing at all levels. 1985 heralded the foundation of SARD – Sigma Advanced Racing Devlopment. SARD is involved in the All Japan GT races as Toyota Team

A look at some of SARDs typical racing setups gives an insight into how the company has come to understand racing and its nuances.

SARD: Tuned for Drift

Drifting places more important on sliding the car sideways, albeit controllably. This is achieved by lowering the center of gravity and allowing it to spin its drive wheels easily. Beyond allowing drifting this setup also makes your car look great while drifting.

Suspension: To achieve the previously mentioned spin in the drive wheels, the steering wheels are given excellent grip while the drive wheels are setup for low, or in some circumstances, no grip. While this may sound counterintuitive it acheives the desired goal of drifters. In additon steering input should be sharpp and precise. To this end cars setup for drifting by SARD tend to have quick rack or lengthened steering arms for superior precision. On top of this springs and shocks are set to the harder end of the scale. All of this together gives your car better sliding performance.

Brakes: SARDs reccomends lower temperature brake pages for the front of your car as this provides decent initial breaking power and helps with forward weight transfer, making the rear drive tyres lighter, once again helping reduce grip in the rear. Handbreak cable adjustment is also popular to assist sliding the back of the car.

Performance: Top end power is important here, being able to achieve wheel spin reliably is the key, giving your car maximum drifting performance.

The overall effect is a responsive and nimble cars with handling that is twitchy while at the same time retaining power and breaking via rigid suspension .

Tune with SARD for Circuit racing

Racetrack and circuit tuning is intended for racing and supersprints. It is not intended for road use, nor hybrid setups for both road and track. Vehicles gain ultimate traction and are supremely stable with top end power and acceleration thanks to SARD engineering.

Coilover suspension systems are almost always required but can be achieved with a quality off the shelf product such as this model from CUSCO. Neutrally balancing your car to give cornering performance on the flat and even racetrack is the goal. Driver comfort is not a factor in this equation.

High temperature braking systems that offer consistent brake performance at high temperature during long racing sessions. Opting for slotted rotors can help improve brake performance as well as slightly increasing cooling. Upgrading to larger calipers and, pads and rotors is also advised.

Cooling solutions and high RPM is key – engine reliability is important as your car will be run at full capacity the majority of its time on the track.

Overall this setup gives a car that can tackle twisty corners with the acceleration needed to be both quick off the line and allow aggressive acceleration out of corners. Circuit racing cars typically do not handle bumpy roads very well as they are designed from the ground up for the groomed surface of a race track.

Touge is the winding road spec

Tōge means pass in Japanese. It refers to the type of road selected for a race more than the style of racing. A driver could opt for drifting or a more traditional approach to the race. With this in mind it is easy to see that any tuning setup could be appropriate for a touge encounter. Because the track tends to be windy and narrow quick acceleration and cornering ability is important. Due to the race track being a public road and not a groomed surface suspension cannot be as low, stiff or unforgiving as a car tuned for a race track.

Finally a car tuned for drag aims for traction and power, these are the only attributes to care about. Takeoff and quick acceleration is all. Turning is an afterthought. Street brakes are sufficient in most cases due to stopping power from cold. Few drivers tune their street cars with this style.
