just a quick question....
why is it called 4040? is that just a part number or does it refer to 40% front 40% rear....but then that wouldnt make sense right?

isnt it supposed to be 60 front 40 rear?

i bet its just a part no.

????

 

good f'n question

It's the number stamped on them

Small Civics have 3030's
EX's/Si's have 4030's
and The 4 disks have 4040's
