Other Key points

Brakes up from the D3 to D3 Bi-Turbo 300mm/300mm fr/rr to 330mm/336mm
The engine`s radiator has been increased in size for greater cooling, D3 to D3 Bi-Turbo
The manual gearbox is up from the ZF SG6 - 37 to the ZF SG6 - 53 ( the `37` and `53` refering to kg*m of torque)
The SWITCH-TRONIC box is straight out of the B3, and loosely based on the 6HP19 TU, with an extra planetary plate and different flywheel for the 100millisec up-shifts in spite of the torque.
All driveshafts, the prop-shaft and two half-shafts, have been up-rated for more torque through-put
All software is new, with no take-over from D3 to D3 Bi-Turbo
Straight exhaust with no rear box, akin to a race exhaust. Meaning better sound and increased throughput, allowing the new D3 to rev to 5,200 rpm.


this is all good stuff
