Ideas on custom built strut tower brace?

I want to install a strut tower brace on my stock 2014 FRS and I was curious if anyone has built their own? I feel like with some metal, a welder, and some measurements I could build my own and just bolt it onto the top of the struts. A few things I was wondering in particular is:
1. can you keep the stock braces that connect up near the firewall and have a strut brace going across the motor?
2. What metal does everyone recommend and at what thickness?
3. Any other info Iím not thinking of or havenít mentioned would be greatly appreciated.

1. Yes
2. 4140 Seamless. Material thickness will depend on design, .065-.095 should be plenty.
3. The mount to the tower itself is going to be the part that is tough to make cleanly if you don't have a good plasma.

1. I don't see why not. You might need longer bolts.
2. Stiff metal tubing.
3. It's easier, much easier, to just buy one. Also lighter, less likely to damage things, and probably better made. I mean, if you were gonna do a pro job, you'd have already done it is my guess.

While it's almost insulting how simple a strut tower brace is, for the price of them...just buy one.

there are only 3 reasons to build your own.

1. because you can.
2. because you have the tools/shop.
3. because building one is more fun.

there is no cost benefit.

There isn't really a performance benefit to them unless you're running MUCH higher spring rates and have replaced all the bushings in the suspension with spherical bearings. The amount of deflection measured on a bone stock car is tiny, Grimspeed did lots of testing and it's very minimal.

But no one can see my bushings and spherical bearings. How are they going to know it's a mock race car ?

Why do people add weight to a car with so little power. Like Strut braces, big ass sound system, fat tires/rims, Yeah...I get the race car look...but it's got to be embracing when your race car gets beat by a weight reduction stock looking 86 and your girlfriend is laughing at you because you got your ass whipped. Anyways if your adding anything at least try and remove that much in weight so your not adding to it. Just my 2 cents

Remove them, tie a string in their place just ever so slightly snug. Lift up one tire a couple inches and see if there is deflection. Ghetto, but worth a shot.
