The Vredestein Ultrac Sessanta is the newest ace in the Ultra High Performance (UHP) segment. The Sessanta is based on the strong points of the Ultrac series and has been optimised even further to give very good steering and handling characteristics. Giugiaro Design has given the Ultrac Sessanta an innovative design, with a line pattern that clearly shows that performance comes first. The name Sessanta refers to the sixty years of Vredestein's existence in Enschede. In tribute to Vredestein's unique collaborative partnership with Giugiaro Design, "sixty" will be written in Italian: sessanta.
Parametric design - from the drawing board to the shelf
The Ultrac Sessanta is designed parametrically. This means that the tread construction, shape and contours are optimised for every size using mathematical formulae based on design parameters. Each size of the Ultrac Sessanta therefore offers maximum design quality.

Corghi is the world's largest producer of wheel servicing equipment, and a leader in technological innovation, demonstrated once again by the recent success of the Artiglio Master tire changer, the world's first truly superautomatic machine of its kind.
The Corghi Artiglio 50 AM 50 and Artiglio Master AM26 both lack three things that can, and will, scratch rims:
There are NO rim clamps, so we can't leave clamps marks or bend the metal under a chrome finish. |
There is no shovel on the side of these machines for break the bead, so there are no scratches on the inside of the wheel. |
And finally, we do not have a tire bar, which can scratch the edge of the rim, or worse yet, unzip the chrome or clear coat finish.
|
In addition, we also use a pneumatic bead pressing tool instead of clamping the wheel when installing a tire.
For wheel balancing, we use the Corghi EM8570 QL-RR. State-of-the-art sonar reads the spinning wheel and tire assembly to help measure and eliminate radial run-out and eccentricity. It also features a computerized optimization program which helps reduce the amount of weight necessary. We also have the ability to hide weights behind spokes on certain rim designs, where the customer would not want to see a piece of lead weight sitting in the middle of an open spoke design.
