As far as finish goes, with an all aluminum brace, I'll just leave the finish as is. With steel brackets, I could get them zinc plated, without too much more expense.
Here's a copy of an e-mail I just sent to the se-r list:

The seat fits back in place fine. You don't notice
it's there, unless you push back into the seat real
hard - It would probably be the same with Omer's.
Omer - care to try it?
The bar doesn't stick out past the 'seat mount
flange' much at all. I'm also going to use 7/8" or
3/4" hex in the final design.

I have only driven home and back to work since installing
it, so I'm not sure yet.
Read this thread:

"You are exactly right. It made a *very* noticable difference. The car understeers much less and will hold a line much better. I can even get the car to drift now rather than plow, but the rest of my suspension obviously helps with that also."

I used 5/16" thick with counterbored holes for the flange
nuts because that's the closest size we had in stock.
The final design will be 3/16" or 1/8" steel, or 1/4"
aluminum with c'bored holes for the flange nuts.
Also, look at your front bar. If it's like the 'Courtesy'
front STB, the brackets are stampings, with formed ridges.
These add a lot of strength, allowing the use of thin
sheet metal. The center bar is solid aluminum hex bar,
it is pretty rigid.
Estimated weights for complete brace:
Steel brackets, blocks:
w/ 3/4" hex Al bar = 6.5 lbs.
7/8" = 7.3 lbs.
1" = 8.2 lbs.
Aluminum brackets, blocks:
w/ 3/4" hex Al bar = 3.9 lbs.
7/8" = 4.7 lbs.
1" = 5.6 lbs.
The first one was made on manual equipment, with higher
quantities, we'll use the CNC's and will be much faster.
Ballpark pricing so far:
5 @ $85, 10 @ $65, 25 @ $55, 50 @ $50.
I think we can make them for less - if there's enough
interest, I'll have the CNC programs written and have
a better estimate on the price.
