Hi, we’ve been racing kit cars for the last 5 years and have already drilled our chassis to lighten it as we saw other teams had a few years ago. We’re taking part in the KMF competition this year and the rules say we can no longer drill the chassis for anything but fixings. What can we do? We don’t want an unfair advantage but not sure how to put back all the holes! We could put extra weight in the get back up to same as an undrilled chassis. Any ideas Greenpower?
