Michelin Energy XM2s all round, running at 48psi.
Lower grill block, mounted behind the grill, and made of plexiglass to keep the "stock look". Other than the cable ties showing, it's virtually invisible.
LED running lights, as I used to run with headlamps on so idiots saw me before they pull out.
Radiator fan light in cabin (have cable through firewall, just need to finish it)
Upper grill block (depending on how much the fan is running already)
Smooth wheel covers - possibly mod existing covers with plexiglass over holes.
rear wheel skirts
