Carbon Fiber Strut Tower Brace - D2B Different

[jwoodland]

So Santa dropped this off the other day....



I've been looking at all the posts on various Strut Tower Braces and really likes the TRD bar but could not justify the price. I was mostly interested in the look and if it yielded any improvement in handling it would be a plus.

I must say that there was no real noticeable improvement in handling but, I don't drive to push the limits anyway. It does seem like there is a bit less hesitation when taking a turn but could just be me.

As for the look, the carbon fiber is spot on what I wanted.







I've compared this with my buddies TRD Strut Tower Brace and except for the TRD tag on the bar I don't see any real difference. The D2BD Motorwerks carbon fiber strut brace is made out of a real carbon fiber tube, with billet end caps, black powder coated brackets, and zinc coated hardware.

The best part is the price was only $99.00 from Dare 2B Different Motorwerks. - See more at: http://d2bdmotorwerks.com/i-15908730....H8aLd6JD.dpuf

The craftsmanship looks to be great and installation was super simple. If you are looking for an alternative to the Carbon Fiber TRD Bar, give this one a look.

The way this is mounted makes it look like it literally does nothing. To be honest, most of the aftermarket strut bars probably do nothing as well. That being said, IMO there isn't anything wrong with cosmetic mods.

Don't know about the TRD bar, but the STi model was designed specifically to do this:

When not bolted to the vehicle, this brace flops around in a most un-brace-like fashion.


Under the car, it gets even weirder. Just behind the engine, two “flexible draw stiffeners” solidly connect both sides of the front crossmember to the body. Or maybe semi-solidly is more accurate because while these draw stiffeners resemble rigid tie rods, they actually telescope a bit under load.


Per Yoshio Hirakawa, the head of STI, the goal of all the newfangled mods is “zero hysteresis driving” — that is, less steering lag and a more linear response from the car. Additional goals include increased high-speed stability and a flatter, smoother, and quieter ride.


How is all of this possible? Some of the applied technology makes sense. Hysteresis is the lag between when the steering wheel of a vehicle is turned and when the vehicle actually begins to turn. Reducing hysteresis has been achieved in sports and race cars by increasing body rigidity via traditional braces and stiffeners. Slop in the chassis from soft springs and rubber bushings can be lessened via harder durometer substitutes, including solid mounts or metal spherical bearings (which the tS also has in the rear suspension linkage). These provide little to no give whatsoever but then introduce other problems, chiefly harsh ride quality, as road vibrations have nowhere to dissipate but up through the seat, steering wheel, and ultimately the driver’s fillings.


This is where the innate flexibility of the BRZ’s chassis and the controlled flexibility of the tS parts seem to work together. STI engineers explained that the flexible strut tower brace and draw stiffeners promote rigidity only in certain directions. The spherical bearing equipped strut tower brace apparently adds structural support across the shock towers for great steering response while also allowing for a bit of vertical movement that is key for maximum tire contact, and a smooth ride. Same goes for the draw stiffeners mounted to the undercarriage; tension within the shafts keeps the wheels running true, even under loads that would cause unbraced wheels to lift or deflect...
