Back to my custom tubular frame progress page - Main Index

 

I traveled down to Oxnard to check the status of my chassis at JLS Motorsports. Lance has been extremely busy in the Winston NASCAR Rracing Series Champoioship circuit with his #48 "Toys R Us" car now in forth place in points.
Structural basics, good handling requires adequate chassis stiffness, this means the frame structure must be rigid enough to resist bending and twisting. In order for the roll bar and side bar tubes to be effective they have to be mounted on to rigid members, the front and rear bulkheads offer this solid type of foundation.

The NASCAR 22-gallon fuel cell is now fully mounted

You can see the bracing and triangulated tubing method of this chassis design.

This type of front and rear bulkhead design offers improved lateral strength to the chassis while providing an excellent base onto which the roll bar tubes can be mounted... a roll bar and side bars are only as strong as the members they are mounted on, so building strong bulkheads are recommended. Rigid bulkheads also add to the frame stiffness, so there is a double benefit from their use.
Lance has built in an anti-squat into the rear MacPherson strut suspension. I ordered these MacPherson struts from RCC, they are for a Fiero with the 11" brake kit.
My primary reason for having a tubular frame is the safety aspect. Crash protection for the driver and passenger is one of the frame and roll bars primary purposes. By making the total structure stiffer, it becomes stronger in a crash (should that ever happen).
This is not my engine, it is just in place for Lance's team to build up my exhaust system, Lance wants to put in a 383.
RCC suspension The sheet metal is now being shaped and cut for the bottom
The seat tracks are being installed, but I will not be using the fiber glass seat, I am going to install Recaro seats.
That is my body on the left and directly behind my chassis in the background is another CRP 6.0, this car belongs to one of Lances's employees (NASCAR Toys R Us driver) Tommy, who is building this car to break the Kit Car land speed record.
That is my Fiero steering column that Lance has mounted in place... one of the few Fiero parts that my car will end up having. This is a quick shot of my son (copilot for this trip) and you can see the size of my rims... and in the background is actor Charlie Sheen's cobra that Lance is building for him.
