Ross Sport Gearbox overhaul kit & RS Ratio Conversion Kit
Kit contains RS 4th & 5th Gear Sets, together with full set of bearings, synchros & sleeves
Direct replacement for GSR 4th & 5th gear pairs in Evo 4-7 gearboxes.
Installing the shorter RS ratios will decrease the top speed to approx 155mph, but allow for optimal RPM drop between gear changes in most circuit and sprint applications.
For road going applications these ratios combined with the 4.11 final drive offers a very good solution for higher powered cars that need more top end speed & ability to cruise on the motorway at sensible RPM.
