ac schnitzer rear strut brace installed pics

here are the pics of my ACS rear strut brace installed. installation was a little difficult, but fitment was perfect. suspension definitely feels more rigid on the rear, but i'll get everyone a full review after this weekend. got 2 full days of tracking on saturday and sunday!

sorry for some blur in some of those pics, i just took a few quick point and shoot shots.

I have never understood the benefits of a multiple piece strut brace with mechanical pivots in its construction. Your rear mounting points can still move significantly relative to each other in the vertical direction. Not a mod I would waste any money on.

I was about to voice the same concern. You might be able to get around the problem by drilling a through hole an inch away from the pivot (toward the wheel), and sticking a bolt through that to restrict rotation around the pivot, but there isn't much space, and the part might develop cracks.

Nice! You beat me to it! I want one too. We installed one here on a customer's car. You can feel a substantial difference in the handling of the car. Feels more flat with less roll. Let us know how it feels on the track this weekend.

Congrats!

Congrates!
was that customer TK by chance?

the car feels very much so more flat. the roll is virtually eliminated. so far, just based on zipping around streets and highways near me, the difference in handling is worth the cost, but i'm sure it will really pay dividends this weekend.

it might work for a street driving but definitely crack under heavy driving on the track ...

The design ACS went with is very simple and not very practical ...

We shall know by the end of the weekend if it does not hold up. I am sure Blake will update us as to the results from his track day.

that's completely asinine to think that's it's simply just going to break because it's made in more than one piece. i don't think acs would put out a product that is designed to fail. i'm going to put it through 2 full days of hard use and i don't have any intentions of seeing it break. it's a very solid, well machined part. it fits very well in there and won't be going anywhere.

There is probably no reason for it to break the way it is now. The failing part discussion was about what might happen if you were to constrain rotational movement around the pivots with another hole and a bolt.

well i was never passed today if that means anything car handled beautifully in the corners, a lot more planted with a ton less roll versus my last event.

No disrepsect but I challenge this observation. For one not being passed is entirely irrelevant. Secondly, we all have a tendency to feel what we want or expect with any modifications. A similar phenomena happens with intake/exhaust mods. Your butt dyno (and obviously brain dyno) gets very confused with a louder and sportier sounding car and then it really feels faster, when in reality the car could be performing identically or even worse.

The design of the particular component looks way too flimsy in bending and torsion to offer any stiffness improvement to an already stiff chassis. Furthermore the kinematic joint we already discussed earlier produces a clear pivot point that simply can not resist a key type of movement that such a design should.

The picture below shows an example of a front strut brack that has no kinematic joint - said simply it is a solid one piece design. Such a design can resist many types of relative motion between the front strut towers. I would guarantee a measurable stiffness change when using such a design. However, detecting it in a totally blind test would still be difficult.

The second pic shows a similar solid design rear strut bar.

Hi swamp2,

Not trying to start an opinion war or anything, but this topic has been discussed for years...remember Neuspeed? They made a solid construction strut brace for the GTI crowd with this claim. Tests were done, and the benefits over a pivoting or multi-piece strut brace could not be concluded.

The fact is that you do feel a difference it the roll and flatness of the car after installing the rear strut brace. Not like you "feel" horsepower gains. It ties the body together between the upper end of the strut towers. This fact alone makes the body stiffer. Now can a solid bar make it stiffer? How much stiffer? Will a triangle bar welded between both struts and the rear of the truck be even stiffer? At the end of the day, with this bar you have an easy disconnect feature which is not available with the solid bar design. No need to remove all of your interior as in the picture above. Some of us still need our trunk sometimes. IMO this is the perfect solution for a rear strut brace.

Again, just giving the benefit of why ACS made the bar this way.
