PM sent to you doublecrossed...I can answer every question about the transbrake.
I just put in a complete A&A transmission with their transbrake.
One thing right now. I think it would be very hard to pull the front wheels on the street, simply because of
NO TRACTION. The drag strip is fully prepped and
"sticky".
Launching off my transbrake @4000RPM on the chip my front wheels come up about 2 feet in the air for a distance of about 20 feet off the starting line...but again, that is at the track.
I also have the complete CalTrak system including their bars, mono-leaf springs and front and rear shocks and my front end is set up for 5" of free travel.
Although My car is 100% street legal I haven't driven it on the street since the new transmission install...but I just don't think I could get enuf bite to pull the wheels in those conditions.
You MUST have a DANA with your heavy car and you must have 1350 U-Joints front and rear....plus other stuff including a front motor plate OR the Moroso steel motor mounts, otherwise you will blow the rubber mounts plus the special Hoosier Stiff Sidewall Drag Slicks otherwise your heavy car will literally "crush" your tires on launch unless you have 32 inch tall tires that are at least 12" wide, regular 28" tall tires wont handle the brake launch..I put on 29" Stiff Sidewall Hoosiers with screwed rims and 17lbs of air to handle the launch. You also need a converter that will handle the transbrake.
My ET's and 60 foot's improved using the brake.
I can now also cut a decent light now with the brake.
In my opinion the trans brake is the best thing ever.
