After reading the other Cal Tracs thread I noticed the mention of minimum 5" upward front end travel needed for Cal Tracs to work properly. I have maybe 2" max upward travel when sitting at rest and none when I am against the converter foot braking. Sometimes when I foot brake I will launch at idle (900RPM) on the 2nd yellow and the car gets the same 60' times as going against the converter at 3000RPM which is all my brakes can handle (it's a 5000 stall). I was planning on getting a set of Cal Tracs and using them and also trying a trans brake with them but if I don't have enough front end travel I will need to remove my coil spring spacers and let the front sit down. Right now the front sits level with the back (car is level with 28" rear and 26" front tires having the 28"s tucked in the wheel wells and the fronts with a fairly large gap above them to the fenders). If I remove my spcers and set the front end back down to get the 5" of upward travel, will the heavy nose rake affect the weight transfer using Cal Tracs? My front end will also be mushy (soft) compared to nice and stiff as it is now. My #4 and #8 cylinder centerlines are even with the front spindals which means the engine is very far foreward in front of the front suspension. Can Cal Tracs still work with this much weight on the nose plus the nose being low compared to the rear? My car is going in the shop this coming Friday for chassis, headers, suspension work (delayed 1 week from chassis builder's father dying). I am still undecided on the Cal Tracs since I read that front end travel requirement and to whether my car will work with them or not. Right now my car squats hard and picks up the front at the same time since the front has very little travel (nearly topped out at rest). Please help me decide what to do. I can keep what I have now and add an adjustable sway bar to my existing setup to level out my launches or go Cal Trac route. Since the price for Cal Tracs are not expenive I might be able to try them out anyway but the mods I must do to use them are not as easy to undo if they don't work well. I need some suggestions please. BTW this is for a stock 6 cylinder suspension Pinto wagon (street car) and hopefull mid/low 1.30 60' times. Alex, I need your contact info and your input along with anyone else experienced with Cal Tracs.  ------------------

The Cal-Tracks will work great once you get the front end loosened up.
To hook any car you need one of two things to work.
A) a mechanical advantage such as controlled clutch slipage that eventually locks up
or a converter that will do the same thingor, more common B) weight transfer
Without a loose front end, you cannot have weight transfer and you will never plant the tires.
Don't worry about your car being nose heavy or front end biased.
65-70 Mustangs are the worst nose heave cars there are.
Have you ever seen any of the FE powered NHRA/IHRA stock eliminator cars that pull the front wheels four feet off the ground?
90% use Cal-Tracs with very loose front suspensions.
