I'm going to be doing x braced door bars on the driver and passenger side. I don't need the x brace in the back AFAIK.
The motor combo I'm putting together should put down 1100whp. Should be enough to go 160's in the 1/4 from calculators I've seen. I just want the whole car to be as safe as possible. I'm not super concerned with adding weight in the rockers. I was planning to mount the main roll hoop to the 2X2 rocker bars, aswell as the A pillar down tubes. I figure this will make the car more rigid and keep the cage as far out of the passenger compartment as possible.
I will be welding in two tubes that connect the rockers side to side. This will function as my seat mounts.
I really would like to do a 25.2 chassis spec, but its alot more bars then I'd like. I'm just trying to build a chassis that will be safe, with minimal impact on the drivers compartment. I will be driving this car on the street so I'm trying to tuck the cage against the roof as right as possible. Also, I'm going to mount the seats as low as I can to keep my head away from the roof bars.
I'll post pictures later of the revised cage as I intend to build it.
Regards,
Justin
