Scaling problems!!! Help

[crateracer16]

Ok. I missed the first race tonight because I couldn't get the scales to come out right. I just got this car too. 04 bms mod. 4 bar. Springs are rf 750 of 650 or 175 rr 225. Lr shock in front spring behind rr is coil over in front. No matter what we did the rr was always heavier by at least 100 lbs. I just can not get any wedge in the car. We've gone over everything 10 times tonight and we can't find an issue. Nothing is touching or binding anywhere. We even went as far as pulling lower a arms to check jacking bolts and plates for a bind. Everything looks like it should. Measured the chassis and it is square(thought it may have been bent) I weigh 290lbs and thought I would have too much wedge but no. We put the car on 2 different scales and the same outcome. Someone told me you are supposed to pull the lr axle out to scale. I didn't do that but would it cause this headache? Any suggestions. I would like to go to a practice session on weds but want the car to be close on the scales. Thanks

Is the rearend squared in the car?

[crateracer16]

Lr is leading by a half inch.

Pull the axle. Also it maybe obvious but be sure leads are right. When I scaled mine last weekend I had similar problem and had the rf plugged in rr. Had them swapped. Was simple mistake that I scratched my head over for about an hour. Try pulling shocks too

What will a rr heavy car do? Would it be a little more tight? Thanks.

Put it back on the scales. Turn the RF weight jack down 3 turns, turn the LF weight jack up 3 turns, go to the LR and put 3 turns into it and take 3 turns off the RR. If that doesn't get you headed in the right direction, let me know.

With your body weight, you may want to put 90# in the seat and floorboard the first time you scale. Most chassis builders baselines are for a 200# driver. Some gie reduced percentages for other driver sizes.

How about posting your wheel weights?

I'll argue all day long, leave the shocks hooked up. You race with the shocks on the car, scale it with them. You will find a huge difference if you run gas shocks, too.

A bent shock will cause a problem like this. So will the rear springs rubbing on the birdcage or bars.

Good luck, send me a PM with any questions you may have.

The plutonium under the hood must be throwing the scales off........
seriously though do the wheel weights change when you push down on the car?
tire size and air pressure right?
If you jack up under the center of the housing with a 100lb RR bite the left rear should come off the ground first

Lets start with the basics. Is this the first time you scaled this car? Are you scaling with or without the driver? Is it possible the other driver was a big fat dude and all the ballast is on the RR to counter the fat guy in the seat? And now you are a skinny guy and the right side is heavy. You can crank on wedge bolts all night long. If you want to move weight, you need to physically move weight.

Joe: His post says he weighs 290 so he's definately not skinny. I had a similiar problem last scaling, started over by resetting the ride heights to builders specs. I then adjusted the screws except i put twice the rounds in the rear than i put in the front. Ride heights are right on and weights are as builder recommends. Doing it this way works for me. Agree with LM, put 90 lbs in seat before doing any measuring on car. Maybe just start over again. JMO

Lr wheel weight was 442 and rr was 648. Sorry don't remember the front weights. I'll have it back on the scales weds. I believe I found a bent shock. Waiting on the new one to come to rescale it. This is the first time I scaled it and I was in the car during the process. I'm going to start over from scratch. Thanks guys!

unhook your shocks also.if its on a pull bar unhook it also.

[washeduptoo]

Unhook Pull bar?

[dirttrackrocker]
