Hello,

We offer a 3-Point design as well with the additional cross bracing, we offer both a bolt in and weld in design. Below is a link to many style of SFC's we offer and also a picture of our 3-Point design.

As for the differences between boxed and tubular, either will work 100% fine, a few differences would be...

The tubulars tuck up tigther and can not be seen from the side of the vehicle where as the boxed style can be seen slightly. The boxed do not reduce ground clearance but do hang down below the pinch weld approx. a 1/4"

The 2-Point tubulars are also 4lbs ligther then the boxed and are offered in a bolt in option if needed.

If you every plan on running a torque arm that welds into the SFC's the boxed style will offer a better weld point for this.

Our SFC's- http://www.umiperformance.com/Search...?CategoryID=42

If you have any questions please ask. Thanks Ryan

I installed the UMI 3-point bolt-in SFC's on Saturday. They bolted right in. No grinding or cutting was needed. Took maybe 45 minutes from start to finish. That's including jacking up and lowering the car.

The car rides so much better now too. I didn't think SFC's would make THAT much of a difference. Going over speed bumps now, the car feels super solid.

Just read the directions carfuly and not torque down the tunnel brace bolts to 72 ft lbs like I thought it said. I only broke one bolt.

Our boxed 2-points weigh in at 28lbs a set, our tubular 2-Points are 24lbs and the 3-Point system is 36lbs.

Hope that helps!

How much torsional rigidity does the third point add? I was thinking of putting in a 6 point cage, and figure that a 2 point tubular would be a good way to eliminate the rest of the flex. If a 3 point really offers much more strength, I would get that instead of a 2 point ...
