BMW E46 325i Transmission Conversion

Sebastian came to At Speed Motorsports with the desire to convert his automatic transmission BMW 325 to manual transmission.  After much discussion he decided to go with a BMW 5-speed transmission, which is a direct bolt on.  That being said there are quite a few things that need to be done to convert from the automatic transmission to a stick shift.  A new pedal assembly must be installed, which includes a smaller brake pedal and clutch pedal.  A new clutch and master cylinder will also be needed, along with all appropriate lines, hoses and wiring.  In addition to the new manual transmission, clutch, flywheel and transmission support cross member, a new, longer drive shaft will be needed to connect the transmission to the rear differential.  We can't wait to get Sebastian rowing through gears in his modified 325.
