Hi, I am currently trying to complete the build of a modified road Mini for use on track days and sprints.
Currently installing an aluminium plate over the parcel shelf to block up the enlarged (by a previous owner) speaker holes.
However the main problem is how to block the gaps between the inner wing and boot wall on both sides. The gaps look a bit too wide to just use fireproof RTV sealant.
Any useful advice which will be passed by scrutineers would be very much appreciated.
