Oh yeah! I forgot they did that. Yeah just grab a thicker piece of sheet for the flange and tap it. Easier route IMO.

I agree also, what size tp did you end up using and what what the thickness of the flange?

On my race car it's just completely removed.

As a side note you can also reinforce the sub frame and run a strut-> subframe -> strut brace and have similar results. Mine seemed fine with it removed, and there is a LS7 autocross S2000 that is fairly successful without it in place. If I was doing TT again in my car I would do a X brace between the frame/towers with adjustable rod ends before I replaced it with a 2 inch tube.

Cant say much about 'impact zones' since my frame rails are chopped 5 inches from the spindle edge and I have no bumpers except a removable bash bar that mounts to my rad support, but yeah...

Not that it is relevant but he and his cross bar survived the collision with the tree and the roll over yesterday so thats a positive!

Unfortunate but positive in the aspect of this thread lol

Thanks for the post man, that's basically what I'm going for with a smaller diameter pipe!
