Floor should be welded in this week.
I have bought some FIA Carbon seats, about 7kg each, plus the seat bases. I think my old seats were about 35kg for both all plus the bases.
Still debating if I should add the Roller Barrel Individual Throttle bodies, Mark Shead and Mark Walker say that will really aid throttle response which is probably the worst part about Turbo cars in my opinion...even if the EFR makes a huge improvement over the old skool turbos.
