12 point cage to 25.5 spec 7.50 chassis.

The 12 point cage I had was good for an 8.50 tag but while the car is stripped we thought it a good idea to upgrade the chassis and cage to 25.5 spec.
This is what we had previously;

Just the sill bars to put in on monday and relocate the shifter closer to the steering wheel and that part of the work should be done.

Interesting :D
Adam - is yours a full tube chassis? I was under the impression that you had to be full tube to go to 7.50 (which is why mine is staying at 8.50). Looks like some nice work there

"Two new SFI specs have been accepted for cars running 7.50 to 8.49. The specs are 25.4 for tube-chassis cars and 25.5 for OEM frame, or unibody-style cars. These specs will be required on new cars and recertifications effective Jan. 1, 2005, or at this time if the car runs faster than 180 mph.
