i dont know but my 550cc runs max of 57% with car making 320bhp. so to get 300 something like 440 be enough, but then again its nice to have bit of extra incase you change your mind
would i be able to use 440's because i was just looking threw my mates unit and he has a brand new set sitting in a tool box and said i could have em for 100 quid
is that a fair price and would they be suitable to use on a starlet running 300 bhp??
