I am currently running around 400bhp an looking to increase this throughout this year I will be keen to get a stronger gearbox in first and want to retain the DCCD in the car. I also fancy having a bit more fuel economy when cruising on the motorway etc. Was informed a PPG with the 5th gear from a P1 would be ideal for keeping the speed up the gears and adding a bit of economy.
Just looking for advice from those that have them or have had both as to what gearbox you found best and why?
