Hi Folks, I was looking for rear strut brace, which I think it will help me in the handling. I found only two in the market, but which one is the best?? . There are M7 Rear Chassis Brace and CARBON FIBER REAR STRUT BRACE. So Folks have you installed one of these? please recomend one to me..also if you can tell me why?

Thanks from now.

 

Spend the money on some IE camber plates instead.

 

What is IE? . I have stock suspension so I don't think I need camber plates, am I wrong?

 

If you still have the stock suspension, I'd think you would be better off with a larger rear anti-roll bar. (anti sway bar)

No, but, if you drive aggressively, do track days or auto cross on occasion it will help a great deal.
It helps to keep more tire surface on the road during cornering and will give you more feedback from the steering.

I have them, IE fixed camber plates, on my current car and the difference between before and after is quite noticeable.
It is also a great way to prevent the dreaded 'mushrooming' that so many of us are getting from bad roads.

The rear bar is also a very good idea.


Hope this helps...

 

Save your money...

Both of them merely bolt to a location that is flexible. The extensions that are spot welded to the body that have the seat back clips moves. All these will di is have them move in harmony.

DDM made one that does work but I think they stopped making them. Theirs is a solid unit that also ties in to the floor liek the M7 one. The difference is that the DDM is a solid one piece unit and the M7 is assembled with nuts and bolts from rectangular stock. Each one of those bolt locations is prone to flex, it's just the nature of the beast.

 

The best rear strut brace would have some form of triangulation and not go straight across from tower to tower. Something that went from the attachment points that everyone seems to use, but then forms an "X" with the base of the opposite tower would be most beneficial. Also the most in the way when doing anything other than racing.

But I have not seen any made this way.

Some of the weld-in roll cages use traigulation to further stiffen the rear end of the car.

 

Give Dave @DDM a call. He can elaborate on availability.

Here's a couple o' pics.





I don't have any from the front, but it used bolts and spacers that attach to the seat latch plate on each side.

 

Oops, I guess that I do.

The M7 one does not do squat.

 

The Cusco carbon fiber one also does nothing except get in the way any time you try to use the trunk for anything bigger than a pair of gloves.

Don't waste your money on a rear back-of-seat brace. There are lots of products that actually improve handling, but those you mentioned are not among them.

 

I can see no anyone recommend to me the rear strut. I have the JCW suspension but I didn't install it yet. So should I get the camber plates with it? to get better handling.

 

Start by stiffening the front end of the car, and add front camber plates. There are three braces for the front end that make a noticeable difference, and one that's a might-as-well.

The three that help are the OEM Cabrio diagonal braces, the lower strut brace from OMP or Mini-Madness, and the lower mid-brace from GTT. The why-not is a straight-line strut-top brace (which does not describe most products - try IE's version).

After all that, your JCW suspension will have something rigid to attach to, and will function quite well. Forget the rear braces - they are snake-oil.

 

Hey Oldrick, do you know if the GTT lower mid brace will work in conjunction with the TSW X brace, or do they use some of the same connection points?

 

The GTT and X-brace use a couple of the same attachments. I've had both, and IMHO, a forward-trapezoid brace (like M-M or IE) plus the GTT mid-brace works better than the X-brace.

 

I just got the M7 RCB installed. I will deffinatly say that it tightens up the back end of the car. I knwo peopel say that it and the STB don't do anythign but I feel that they do.
