Coming soon from Serpent is the composite gear differential for the S411 line of cars. Making use of a lightweight plastic cage the diff features composite material internal gears and a X-shaped cross pin made from the same material. The outdrives are hardcoated aluminium items that replace the original steel parts for even lighter weight. The reduced rotation mass makes for better acceleration and increased overall performance. The original sintered metal gears are still useable with the V2 composite cage allowing for various gear combinations to achieve a different feel.
