Probably the same way the racing teams do it. I'm no welding expert, and I know aluminum isn't as easy to weld but I'm sure there is a way to do it. The Vette C6 and C7 racing cars use the same aluminum frame as the Z06 road car. Yet they manage to weld a roll cage in there somehow. Ferrari also does it too. The 458 has an aluminum frame, yet the racing version has roll cages too.
