Safety is PARAMOUNT and thanks to you have already picked out certified racing seats and belts. I will purchase a TIG welder or get someone to use same on the Roll Cage and joining 2x3 rect tubes. I want to get a tube bender and standardize on 1.75" tube whether it be 4130 0.083" or 0.120 wall DOM. The round tubes would join outriggers at the front and lateral cross member 2x3 tube at the rear. If I can, it would be good to go from outside to outside on the rear to cross the longitudinal 2x3" rect tubes and cut sandwich and weld the 2x3 long and cross tubes behind the seats. Outriggers will be added both front and rear. I want to extend outriggers from the 2x3" tubes to accomodate added round tubes that I would like to run behind or tied into the rocker panels. These are only the start of the project to eliminate the bent upward passengers floor and subframe below it. I reviewed photos and I stand corrected they only extend downward 1/2 to 3/4". John: The 2x3 rect tubes replace the original subframe rails.
If your car weighs in at 2,700 lbs or more then you'll need 1.75" x. And, BTW, DOM tubing of the same dimensions is allowed so the extra cost of 4130 doesn't get you any weight savings.ĮDIT: The above road race tubing dimensions are for a car weighing 1,700 to 2,699 lbs. 083" 4130 tubing is only allowed if the tubing is 1.625" OD. If you plan on running your car with most any road race/track sanctioning body here in the US. NHRA still gives a weight break for 4130 and you can save weight with 1.625" x.
I have no idea where in your car the 2 x 3 subframes are going but the main hoop and door hoops of your roll cage should be tied into the rocker panels, not any subframe that's running nearer the centerline of the car.
TEAM Z SUBFRAME CONNECTOR INSTALL
This will be plenty strong to handle the added HP.It comes down to needs and abilities.if you dont have the need or the ability to install a full frame, then the BD parts are for you. It is tied into the rear of the rockers and when I build the 4 point cage, the main hoop will weld directly onto the new frame. Its mounted half in and half out of the floor pan. And adding the BD subframe connector to a new rail makes things alot stiffer than stock ever was.I designed and fabricate the BD rails and subframe connectors and they are purposley made for the average joe.They were designed to fit over the stock rails to minimize installation.That said, they are not for everyone, I am doing an RB swap and have gone the box tube route for the added strength.I'm using 1.5" X 3" with a. But for the average Joe that just wants to stiffen a failing stock rail, the Bad Dog rails are more than adaquate. This listing does not include the X-Brace.Īvailable in both plain steel or powder coated, these subframe connectors are the ones you want for your early Mustang.True, adding a box tube to tie in the front and rear subframes will be stronger and building a cage that ties into the box tube will be even stronger. Want to step up to an even better option? Pair your subframe connectors with our X-Brace or choose the chassis stiffening kit for the ultimate in performance.
This also allows the subframe connectors to serve as future jacking points, preventing further damage to your frame rails or floor pan. We have found that bolt in subframes pull at the thin metal underneath the car and aren’t nearly as effective as a true weld in solution. These are only available as a weld in option. They closely contour to the floor of your Mustang to prevent any ground clearance issues. This significantly reduces the flex found in early unibody Mustangs and stiffens the chassis overall, allowing the suspension to do the work. These longer connectors weld to the body and frame in four locations, preventing them from pivoting on only two points. Why? With subframe connectors, the goal is to grab as much chassis as possible to minimize flex and fatigue. 120 wall round steel tubing (1.75″ for convertible), these 75″ connectors are longer than just about anything else available. Its a bit messy but best way to cut the floor is a cut off wheel on an angle grinder and an auto body saw. I set the wixey center of the seat bulkhead for side to side and on the rocker for front to back. Get on amazon, EAZ-lift RV jacks, not for lifting but for leveling out, get a Wixey WR365 digital level.
TEAM Z SUBFRAME CONNECTOR MOD
Built to withstand the punishment of racing while maintaining road manners and improved handling on and off the track, the MOD subframe connectors will greatly enhance the ride and performance of your 64-70 Mustang. Im installing Team Z TTF connectors right now. Simply put, these MOD subframe connectors are the best on the market.
