yer we ended up useing an old c4 that was sitting in dads shed i raced home gave dad $200 raced back to the track ripped the broken box out and threw the c4 in, as far as i know that bloody old c4 is still in there and going hard. we thought it was rooted and needed a rebuild but it done the job i dnt think ive ever seen a bloke give so much back to a person when he won his class for the year, i had rums, smokes, and more rums pouring outta me lol. i know he was unable to thank me enough lol he was a like a kid in a candy store when he won that year with a busted old c4
