Cage fabrication headaches.

The car is just back from the roll cage fabrication and before painting, here are a couple of pictures. I am not a roll cage professional so I welcome any comment on the cage design. Only thing I see out of the ordinary is that the daytona door bars are not sticking out as much as some other cars, good or bad I don't really know. Anyways for my club racing I think I am already much safer than stock that's for sure


After some investigation, it seems the roll cage main hoop diagonal is not NASA or SCCA legal, because there is a bend in the diagonal and also the diagonal is not in the same pan as the main hoop. The car is going back to the cage builder for some adjustments and hopefully back NASA legal.

The last photo shows you the diagonal bent and not in the same plan as the main hoop. Also after trying to install my seat we realized the cage did not allow the seat side head restrain to fit, so next time you build a cage, send you seat and fitting to the cage builder as well to make sure it fits, also the harness bar should be placed according to your seat. Even though some parts can be added later to adjust the angle of the harness, better do it right the first time.

Never assume your builder know the local club rules, make sure you print out all your requirements in terms of design, tube size for the chassis class/weight...etc etc..

New cage design.

So far my favorite roll cage design is coming out of Precision Chassis works in Nevada, I regrouped some of their design here:

Toyota has also make their own cage design for the GT86 platform. You can see it in their cup car and rally car, but the main hoops consists of an X shape and not a single bar as per NASA rules, the design is also a lot more complex. still I wish toyota would publish specifications on a roll cage design that is optimized for the t86 chassis.
