Project H-Pattern Cage updates and transmission plans

Doug at Precision Chassis just never fails to amaze. Here are some updates on my hardtop 6-speed Supra. This car will be very similar to my white car's setup, still IRS... just safer with a proper cage for a car running sub 8.50's and over 175MPH. It will be a bit lighter too :)

A lot of people have been saying "I hope you keep it 6-speed" and to be honest that has always been my plan for this car. So, you ask what transmission will be going in it first? The GR1000 synchronized 6-speed. I think that should explain the first goal pretty clearly.

But lets get on with the cage updates. The rear section is complete, with removable chute mount that will be in the license plate area. The floor is about ready to be welded back in permanently. One of the cool things is all the floor bars will be hidden under the stock floor, making for a cleaner driver compartment.

This is the damaged drivers floor/kickpanel all fixed up. This car had some floor damage in this area and needed repair. 


As you might have seen in some earlier pics, the floor was completely cut out. In order to meet rule requirements, the stock floor is now back in and repaired.
