i just checked out the hi spec website.

looks like some goos stuff on there.
i'll give my dad the number and get him to ring them and have a chat about what he has and what he can do with it using some of their stuff.

cheers for the advice mate. he bought all the stuff because it was the reccomended upgrade by the company that builds his kit car. but it actually seams to have lost him brakeing performance.

hopefully he will improve it somehow.
