Preparations for 24-Hours race hotting up

BILSTEIN-MDS suspension tuned perfectly for Aston Martin GT3

Ennepetal, (Germany), May 6, 2013 – Preparations are well under way by BILSTEIN and Aston Martin for their first collaboration in the 41st ADAC Zurich 24-Hours race (19 to 20 May 2013) at the iconic Nürburgring circuit. In order to prepare the Modular Damping System (MDS) fitted to the Aston Martin V12 Vantage GT3 – sporting the blue and yellow brand colours of BILSTEIN – as effectively as possible for the endurance race in the Eifel, the BILSTEIN and Toyota Motorsport engineers had to simulate the track conditions of the Nordschleife for the BILSTEIN motor sports suspension kit. The all-day sequence was tested on TMG's Formula 1 standard 4-Poster test facility in Cologne.

Following the forced cancellation of the test and calibration drives and also the qualification rounds for the VLN endurance championship at the Nürburgring race track due to severe winter weather, the tuning process was begun in the "grey hell" of the TMG test facility without any practical reference values. The original intention was to seek out a promising setting for the MDS and British sports car combination on the race track, under competition conditions. But, leaving nothing to chance, the managers of both companies agreed to arrange an additional test and tuning session in Cologne.

Initially the focus was on collecting high quality data. To achieve this, the Aston Martin underwent a concentrated simulation of the key points of the Nordschleife on the 4-Poster test facility several times over. An entire simulated lap of the Nordschleife then served as a reference. In the next step the engineers used the information they had obtained to determine which spring rate yielded the best performance in combination with the BILSTEIN motor sports suspension. This was followed by precise adjustment of the damping force. For this the technicians tried every possible variant of rebound and compression stages setting, both on the front and rear axles and also in the front-to-rear axle ratio until the optimum setting for the Aston Martin was found.

With its independent damping force adjustment in both rebound and compression stages and the resulting wide range of possible individual settings, the BILSTEIN MDS provides an ideal basis for successful racing. With its ten clearly discernible clicks from one (gentle) to ten (hard), the damping system can be precisely adjusted to meet the exacting demands of the 24-Hour race in the Eifel. Thanks to the continually consistent damping characteristics, the adjustment options of the mono-tube shock absorbers permit exact adaptation to the specific suspension properties of the Aston Martin V12 Vantage GT3.

The technicians of both companies made their final assessment on whether the tuning in the test facility did actually reflect the requirements of the track itself in a single test of the Aston Martin on the Nordschleife during the 55th ADAC ACAS H&R Cup, the second qualifying race of the VLN endurance championship.
