has anyone ever thought of doing this on a fc? its been done on the fd...why not on the fc?

heres a link if you dont know what im talking about

https://www.rx7club.com/forum/showth...e+torque+brace

im thinking of doing this, my engine shakes like a monkey with peanuts. and my mounts are fine, but the engine still shakes. plus this thing helps while shifting.

what you guys think? why havent i heard of anyone doing this?

 

I have one! Its an HKS one I think. Or RB I can't remember anymore...

 

aerodyne makes one

http://www.aerodyne.net/

 

http://mazdatrix.com/h7.htm

they sell the rb one with their strut bars

 

im talking about one that bolts to the engine like on the fd. not a strut bar. i want less engine movement.

 

this one works pretty well too

 

doesn't racing beat have a tourqe brace?

 

Mine bolts to the engine! And the other side to the fender wall on the driver side!

 

PICS!?!?!?!

 

the mazdatrix bolts to the firewall, not the engine...am i right?

 

couldnt find anything from RB

 

the mazdatrix bolts to the strut tower brace which is bolted to the strut towers (duh) and the firewall as well. racing beat also makes one. the rb braces against the fender. there is a writeup about the racing beat one at www.fc3s.org.

 

the mazdatrix is triangular, bolting up to both the strut towers w/ one side of the triangle, and each strut tower connecting to the firewall. On the part connecting the two strut towers, there's a strut tower brace incorporated into the design.

 

im pretty sure this was obvious, but i wanted to make it clear that it wasnt bolting to the back of the engine.

thats why it was called a strut bar....not a torque...

im going to check out that fc3s.org one tonight.

has anyone else done this? why do pple in the 3rd gen forum think this use full but no1 really believes in using it on the 2nd gens?

 

Racing Beat makes one.. I *have* one but wont be installed for a while.. (christmas present... )


Its item #14031... cost $65

 

I had the RB brace installed on my T2.. It was a pain in the ***.. #1 you've got to drill a hole in your driver side fender.. remove 2 bolts on the bell housing to install the main brace and hope that everything lined up properly so the shaft goes in straight...

The shaft interfered with my clutch master cylinder resivoir .. I had to give it a slight bend in order to not put pressure on the cap and still allow me to open it when needed....

After all of that work, the brace did do it's job.. throttle response was quite a bit crisper.. the motor no longer rocked when you hit the gas.. changing gears was a bit easier... there wasn't much vibration transmitted into the rest of the car because of this....

I liked the idea of the brace, I hated the install.. everything worked great until the but that was threaded on the shaft to keep it on the main brace manaed to shear off and strip the threads rendering the brace useless.. I think that my broken motor mounts had something to do with it

I took a look at the aerodyne unit.. and it looks like it's a much easier install and removal.. and you don't need to drill any stupid holes into your car.. I will definitly be replacing my RB unit with one of these soon..

 

Racing Beat has one, I don't know the quality on it but I would expect it to be good coming from them.

 

Aerodyne makes the one you are looking for it is well priced and works great. If it bolts to the front strut tower and then to the intake manifold. Here is a link it explains its function in full detail and it really does work i no longer have any shifting problems now that i installed in in my car. The only problem you may run into with it is that if you have stock suspension and a strut bar you will need to modify your the strut bolts to make them longer so they can have both the brace and the strub bar bolted on them but if you have decent aftermarket suspension it should have come with longer bolts already on the strut mount.

click on original parts and then on rx-7 scroll down a bit
and you will see the torque brace. It costs $95.00 and can be adjusted to be stiffer or softer.

95 bucks for that? that isn't that hard to make... there are two down sides to the aerodyne unit.

1.) what happens if you have a strut bar?
2.) is it ok to stress the upper intake manifold like that?






a better design maybe to flip the mounting plate over and have it bolt up to your alternator bracket or some thing near there.

 

any JDM brands who make a torque brace?

 

I'd figure that if your manifold is in good shape, and secured properly, it really should be an issue.



It also grabs the main bolt of the alternator, or atleast appears that way in the pictures.

 

I have not seen or heard any complaints about the torque brace affecting the intake manifold. If you would go back and read my complete post you would see that i explained the strut bar problem. If you have a strut bar you probably should have aftermarket suspension which comes with longer strut bolts so that you can add more than a strut bar. If you have stock suspension or your aftermarket suspension does not have longer studs you can simply press out the short ones and replace them with longer ones. I know a lot of people simply add a strut bar cause it makes the car look like it is modified but if you dont have a decent suspension set up then the strut bar really wont benefit you as much as the smooth shifting that you gain from the torque brace. Anyhow I am able to run both the strut bar and brace on my car and i love them both and would not like to sacrifice either one.
