BMW ZF DOGBOX
 
BMW ZF S5D dogbox fits to E36 M3, 328 and virtually every other car model due to the compact size! Perfect companion to the Adamat Performance adapter kits we offer! The gear set has a handful of special features built-in. Shifter mechanisms are completely rebuilt, to make them as robust and rigid as possible. Clutch shaft is stronger than original and can be built for other splines as well. Gear set can be fitted any many car models with aftermarket adapters or by bell housing modifications.
