can't hurt you are also way to light on those fronts lightest i would run is a 900 on a street stock mine weights less then 3000 and i run 1100rf and 900lf those 800# are for mods. also try to get your rear % up that way low too

I think you are going to see an increase in your cross weight when you swap your fronts. Might want to swap your rears as well. Just something to keep in mind.

racer17j, How do we get more rear weight without adding balast?

more rear %
try bigger fuel cell with more fuel (thats the easy way out but obviously the total weight will increase)
move battery to rear.
take weight out of front (does the same thing) maybe lighter bumper (exhaust tube) etc.

Are you using the stock rad support? What about the fenders and hood? Throw the rad support in the scrap pile if they'll let ya and attach the fenders with some 1" tubing. Hack the fenders and hood of every bit of extra metal. You can probably save 50-100 lbs easy from the factory frontend sheetmetal.

I'd also use heavier front springs if I were you. My car weighs 3225 and we run 1100 rf, 1000 lf, 225 lr and 200 rr but that's on a big 1/2 mile (.588) that's almost always hard and slick. Run a softer shock on the right rear than the left to get a little more transfer too.

you could run taller tires on the rear put shims in the rear springs and like the other said gut everything you can out of the front also if you can find a 80's cutlas rear bumper those suckers are pretty heavy throw one of those on her bigger cell and always run her full battery in the trunk. run a heavy wall tubing in between the rear frame rails

jacking the back of the car up and/or the front will not ad weight or lose weight front and rear. same as putting tilt in the car will not increase left side weight. it is a physical impossiblity. sorry. if you don't believe me, put it on some scales.
the only way to move weight front-rear/left-right is to physically move mass in the car by moving components or adding and subtracting weight from areas.

Rocket 36 are you sure about this? I can adjust the height on one corner of the car and add weight to that tire. If you raise the front of the car and or lower the rear it WILL add weight % to the rear of the car. I have done and seen this on my scales. Not alot but it does, but I think ballast is your best option when wanting to add rear percentage. It really depends on WHERE you put it as to how it will effect your car.

Ad for the record I have been running the swap on the front springs the entire year. It seems to work for me. Do you think there could be other factors causing the inconsistency?

Any bind in the chassis or if the rf a frame is bottoming out will also cause it.
