Titanium Racing have released this new upgrade product for the Schumacher Mi4. This new layshaft has been shortened to reduce the possibility of rear end tweak and it eliminates the link between the left and right hand side of the bulkheads. This allows the two top carbon torsion plates to operate as they should, providing a great degree of controlled independent flex. Made from aluminium, this shortened lay shaft claims to provide for a more uniform and deeper flex, aiding rear end traction. Most notably transmission noise has also been reduced thus increasing transmission efficiency.
