I've got to install a seat bracket before Cascade Lakes, otherwise I might not pass tech inspection.
Been looking at a number of different options. First of all here are a couple of pictures so you'll see how much space (and angles) I have to work with. Front view: From the back at the top: From the back looking down: Was thinking about making an L bracket that I can bolt to the seat (the 2.5" section between the holes for the seat belts. I'll use something like a carriage bolt with a rounded head on the drivers side of the seat. Found a couple of brackets for the roll bar that will work: Or use a couple of these with the same L bracket Coleman also makes a parallel one that might be easier to bolt up to the L bracket on the roll bar side. Good way or is there a better way. All ideas appreciated! |

The SCCA rule predates the PCA rule.
I was at the PCA race, at Lime Rock. The story is a little different than Brant explained but pretty close. Specifically, the seat didn't fail, it was the aftermarket sliding seat rails. In any case, by SCCA rule, the seat must be able to withstand applied forces in side to side as well as fore-aft directions. FIA seats don't require the back brace if installed per manufacturer's instructions. Randal, how about a flat plate welded to the bar and a corresponding flat aluminum plate welded to the back of the seat. The seat plate would lay on top of the fixed plate so 2 bolt holes could be drilled thru. Advantage - no bolt heads inside the seat. |
