Developed with leading local Schumacher drivers, the Smokem Mi4 Upper Link plate provides Schumacher Mi4 racers with additional, longer upper link positions to dial in their cars. By incorporating multiple link positions, racers can alter the length of the upper link without changing the upper link plate. Apart from the standard 39.2mm spacing, there are 2 additional spacings of 31.7mm and 24.2mm. A longer upper link provides greater roll resistance for a given spring rate and less camber rise. The design is also ideal when running harder carcass control tyres by maximizing tyre contact patch and maintaining consistent tyre wear.
