strut tower brace question
strut tower brace question
i'm pulling my engine soon to do some modifying to the bay and repaint. i've been considering a brace for quite some time now. would i be better to get one and set it up before painting or would it really matter? what would you guys do and does anyone make a polished brace?
also, a 2 point should be good right or is a 3 point really worth it?

In my opinon, Hotchkis is the most popular, because it is by far the most advertised... Quaility is very good with it too.

From strictly a strength standpoint, tying it into the cowl like that doesn't seem like it would help much, but I would think that it would help out with cowl rattle.
cowl rattle??
yeah i think if i were to go with a 3 point i would only do so if it were possible to mount to the firewall, just leaning on that sheetmetal causes it to flex..........i really don't see what it's purpose is?

yeah the black is a little nicer, but i still don't like the mounting point....i mean if you were to step on that part with a little force it would bend....how could it not flex under the amount of stress that a heavy car can see?
I'd say for normal daily driving (or even spirited driving on the street) the 2 point is a great choice. People who push the car to its limits on a road track can justify the cost of a 3 point. Both would look good. I think a polished one would look the best. Or maybe a combination of polishing the actual bar but painting the mounting points to match your color scheme. Thats what I plan to do to my 91z after I get the Evo II kit next year (will be repainting the engine bay and stuff).

hey now don't get all defensive........i mean look at the point of origin. how can that be stronger than say a firewall mount?
i just don't see the reasoning behind it. i guess my point is there is no way (to me anyway) that i can justify bracing something from that point. obviously it must work or people wouldn't buy them i suppose. just from a standpoint it doesn't look strong enough.
i would like to see you jump on it though........might be fun.

I think with what you've done with the motor, the STB should look as stock as possible. It would look great if it was painted body color but that might be a little too much $$.
The BMR bar is nice but I don't like the mounting at the strut towers, looks like removal would be a PITA and trust me, you'll remove the bar if you like to work on your car.
The lip on the firewall is plenty strong for it's purpose. Since it is so close to the firewall there isn't much structural issues unless you plan on standing on the STB! The 2 bar keeps the strut towers equal distant and when you turn hard the inside tower will help keep the outsided loaded tower from flexing too much out of position. The 3rd point is ment to supress movement in the forward-back direction, not torque. If it was trying to supress the torque it would definatly have been best to mount directly to the firewall. I guess a good example of this is when you go hard into the brakes the torque arm and brakes will pull down in the middle of the car, this little extra piece will keep the towers and front end from buckling in towards the firewall. I guess you can call it a truss and that probable also explains why it's a triangle and not some other shape.
I love my 3 point edelbrock brace but I've also got TBI, doesn't fit with TPI.
I'd get the Hotchkis brace if you're going for looks and function would be the BMR or other 3 point brace. If you're going to make your own you might as well make it a 3 point.

Anyone care to chime in on the Kenny Brown STB? I'm more about function than appearance. The KB brace looks very minimalist from a styling standpoint, but looks very solid structurally.
czech it out...

do they have any better pictures??
i love all my kenny brown peices, i would think the stb is just as nice.
i have yet to find anything i like, i think i'm just going to make one...probably going to go with chormolly (forgot how to spell it).
i'll post some pics when i'm done! thanks for all the suggestions guys!

From looking at the pictures, first of all I like the looks of the Hotchkis the best. Second, I like the fact that it is a two point, so that means less stuff to work around as opposed to a three point. Also, if someone could help me out here, it looks to me that the Hotchkis can easily be removed at the two joint if you really want to get your hands dirty working on the engine....am I right here? With the others, it looks to me that you're kinda screwed when it comes to temporarily taking the thing out. -89IRO

I have a Jamex one. You can't get them anymore though. They are polished. The picture I'm attaching is not my car, but the brace is the same. I just don't have a pic of my engine with the brace on it yet.

DJ- cool, I think I am going to get the Hotchkis then. One more question though, does this Hotchkis kit come with like full instructions and like some kind of template to show where to drill the wholes and everything? Also, how many bolts hod the thing down on each side- I can't really tell from your pics? Does puting the aluminum piece under each side make it stronger, or is that strictly there to help clear the TPI? Jees, I hope I don't have any hood clearance problems with this thing! I'll probably be scared to close the hood for the first time after I install it! -89IRO

Answer to your questions:
1) Insructions as good as any other for 3rd Gen cars. (brief)
2) Two bolts per side for mounting.
3) Aluminum shims were installed to clear the top of TPI (note! you may not need them).
4) The top of STB will indent into the Hood Insulation. No problems with Hood closure.
Thanks for the compliment on the Engine compartment. The blues
hoses match the blue plug wires and it grows on you after a while.

The part where the brace attaches to in the rear in F****ng stronger than you think. It took forever to drill thru it.
I bet you anything that it does not flex like you guys think. Where it mounts is not going to be flexed up and down anyway...just like the brace thats on the passenger side from the factory..... That is just my opinion.
Where you drill thru the strut towers is strong too. I like mine and it was cheaper than the others and can be had in a number of colors.

what thin metal? what are youy talking about?

I'm probably wrong about it being too thin, but I'm talking about the mounting points on each side of the STB where the brackets get mounted to the strut towers. The metal just looks too thin and weak there to support this. -89IRO

wait till yo go and drill thru it. or better yet go out there and tap on it with a hammer and tell me if it sound thin....The shocks are attached there it cant be thin.

I like the Edelbrock brace for TPI cars the best. It seems to have the best form and function IMO.
Alot of the racers in the NASA Camaro vs Mustang challenge use the Edelbrock so it must work.
Sorry about the pic its the only one I could find. Not my car BTW. Mine is in peices for some upgrades so I dont have any pics of mine yet.

Think about this , how wel is a stb going to work if it has hinges? I would look for a bar that is solidly mounted. If you just want it for looks than go either way , but for a performance stand point , i would say you would have better luck with a bar like the bmr or like wise .
Yeah, wishmaster, you're right, I took a closer look at the strut towers today and I see what you're saying. As for the stb, as long as there is no slack or slop in the joints (hinges), then it should be just as good as a solid piece. Plus, I need something that can easily be removed. -89IRO

Kenny Brown STB
I can't reply on how well the Kenny Brown STB works since I've had it for over 2 years and haven't installed it yet (car's still apart) but examining the quality it looks top of the line for sure. If anyone needs a good picture of the brace please email me drabicki2@attbi.com and I'll snap a few pics for ya.

i have always like the KB brace the most of all the TPI braces. is it one peice welded right? not bolted together like the edlebrock or BMR
KB brace is one solid piece , but i had problems with mine . It didn't sit right . I was hitting the brake master it was about 1/4 away from the firewall . And hitting the plenum . I brought it back , and went to a fabricator . And had a custom one made , then sent it to be powdercoated .

The 2 point BMR is one solid piece and so is the 3 point except for the points that go to the firewall.
