We have had prior approval of Matt Hunt. Today we welded them on BoggeNs B13, fit with no problems. Here are a few poor quality photos. Khong has more, he said he would also post up. Here are a few links to our photobucket photos. I hope this works.
They are made from 11 Gauge 1" square steel, weld on with tabs. Must use a 4 post hoist for install. $300 + 35 shipping. I don't have an offical weight but I will say close to 30 lbs. But remember, it is on the lowest part of your car. They will come powder coated black. We are not sure how many of these will sell, so having a list of commited buyers would be good. Please start a list if your interested. Once we receive your money expect around a 2 week lag time as our powder coater is very busy right now.You can review our other chassis bracing here:
truaxmotorsports.com or do a search for us here Maxima.org We are well known in the Maxima community.
Happy to bring this product to the Nissan community.
Looking at the pics, it's just square tubing cut at 90* and 45* angles. It won't interfere with your exhaust because it doesn't go across the center of your car.
Too bad someone doesn't make something like the Flyin Miata butterfly brace, now THAT'S a nice piece. It's rails piggyback on the stock rails, which bolt through the chassis, and a center brace which ties it all together. The attachment hole on the center portion are slotted to accommodate different exhaust systems.
Oh, and the original poster hasn't been on the board since 3/08, but his contact info is on his profile.

Thanks for the information.
I have also sent him a PM, and an e-mail via his web-site.
I don't think anyone bought a set of these connectors yet. I know they are on one (1) test vehicle, and the Maxima boys rave about them.
Mike K was just commenting (last post Suspension Thread) on how the B13 chassis needs additional bracing, specifically, he mentions sub-frame bracing and foam filling the side rails.
My vehicle is currently under-construction and literally sitting in a body-shop. Which would be a pretty good time to put on a sub-frame brace, if one were so inclined. Not to mention a good time to foam-fill the side rails.
The major point of sub-frame bracing is to tie together the two sides, independent welded in stock isn't such a great solution. Not when you compare it to a "X" brace...even F/F we still have the tunnel for the exhaust and two big flappy sections on either side of it. You need to tie those together, using the strength of the side rails and crossing the center.
The type of brace that G Spec makes for 350Z/G Coupe is pretty nice for a bolt-in, lightweight solution.
The other thing is that much square cut tubing isn't light. At least the weight is all down low.
Whiteline made braces for even the U13 in Aus, I'm surprised something from their product line isn't done up for the B13.
Also check with Mike on foam filling, I recall when he did his Z, he warned against using the wrong type of foam, and mentioned it's got to be done right or it breaks down, traps water and causes major early rust-out.

Where is that article about foam filling b13's from Mike K?
Well-written - IMHO, Mike's a very good writer for making technical info accessible w/o dumbing it down too much.

"Foam-Filling the Chassis
In any high-performance car, it is impossible to make the chassis too stiff. The stiffer the chassis, the higher its natural frequency, making the energy imparted to it by bumps less likely to excite the body's structure. A stiffer chassis enables the use of stiffer springs and shocks without hurting the ride. This is because a stiff, non-flexing chassis transfers more force into the suspension where it can be dissipated by the springs and shocks instead of transferring the force to the occupants. A stiff chassis is also more responsive to roll rate tuning for balancing understeer and oversteer. This is one of the reasons why automotive engineers are continually investigating ways to stiffen chassis without adding weight.
In a final bit of reengineering to stiffen the body, we injected the chassis with catalyzed rigid structural polyurethane foam. Structural foam, in the 2 lb per cubic foot density that we used, can stiffen chassis members up to 40 percent."
There's a lot more in that article, esp the WARNING from Mr K here:
Quote:
"Do not--I repeat--do not attempt to use cheap, hardware-store canned foam. This is not the same thing, and if injected into your chassis, will form a gummy mass that won't dry. Foamseal foam is a professional grade foam, which although it is a little unforgiving to cleanup mistakes, has superior mechanical properties and catalytic curing so it will dry even in an enclosed space."
