Corner weight is set at race prep level with the amount of fuel you plan to start out with and driver on board in full gear or the same weight in the drivers seat. Once any changes are made it has to be done over again and will change a bit during a race of course.

I have not found the article on heel and tow driving and not doing so by some world class championship drivers yet. I read it years ago and it was such a relief since I always felt bad that it did not work for me, I am not the only one and no where near world class like so many of us think they are. Most others consider it an absolute must, why most that do not do it do not make it public knowledge as some have less than open minds about other possibilities and will rant about it, which I expected when I made the post.

Back to the topic at hand, really looking forward to where you are taking this car and glad no more harness bar, either roll bar or cage and not one of those bolted to sheet metal is the only safe way to build a race car, that is why many orgs do not allow harness bars on track.
I very much want to build a roll bar into my car but the multipurpose use and design of the car make a tough one to figure out, so far nothing works right for it.......if purely a track car or I did not have to haul two huge dogs around in it, it would be easy and done.

Alumanized steel for an exhuast on a track only car is a very viable way to go, the main advantage to SS is not going to come up as not enough use and certainly get it more than hot enough to keep it from rusting. There is some gain in SS to keeping heat in the system and away from other things and helping extract the exhaust but not a huge difference. I have built both and never replaced a part I did not do for other reasons besides a performance mod or noise adjustment.
