Here is a sheet metal cover I made to shield the master cylinders and brake/clutch lines so the heat from the close proximity of the headers doesn't cook the fluid. The master cylinders on the new generation Hurricanes are mounted on the floor box along with the floor mounted pedals.
Here is a pix of the master cylinders/lines and header.
A pix of the shield made from aluminum. All "polished" up with scotch bright and WD40.
And a couple of pix of it installed.
Hopefully, this should eliminate any problems with the heat. I left it open in the front to connect the reservoir lines.
