Do any of you 1/4 scalers out there use scales to set up your rides? If so, what is a ballpark estimation of the weights at the 4 tires? (lf, rf, lr, rr)
Thanks---looking for a starting point!

the numbers could be anything. percentages would be what to look at.
i guess. i don't use them. i have some and every time i've tryed to use them i dial myself right out of being fast. my advise is get the car fast and then see what the scales tell you. so you can repeat it if your having problems later

I also have a nice set of computer scales that give percentages and cornor weights, but I have found that tire temps did more for my setup than scaling the car. This year we are going to do more spring changing and ride height changing looking for speed and not worry so much about weights and percentages. These cars are much different than a solid rear axle car I am not sure how much scaling helps. I do scale our car if it is hooked up real well just as a refference point...
I don't have my book here at "WORK" (I hate that word) to check on what we had last time I checked it, I will post that at some other time if it will help!!!!...

thats what we have found. tire temps and more experimentation with setup.
trying differenet setup configuations. that has made me faster.
last year i had three different setups on the car. each one i was able to get up to speed but they all had different feels to them. learned alot last year on a totally new track to us. thats one reason we tryed different things.
some guys get the car run well and are afraid to try stuff.
thats what my notes and setup sheets are for. so i can get back if its ugly.

Typical numbers are 35% to 40% Cross Weight, 53% Rear, and 45-50% Left Side. A 35% cross weight is very loose and a 40% cross weight is very tight. Getting a decent left side percentage is helpful. Most don't realize that our cars are actually heavier on the right than left (THE WRONG SIDE FOR TURNING LEFT!). So make an effort to build the car as light as possible and add left side weight. BTW: My WCM and Lightning, when race ready, scale out nearly the same.

My cars for the most part have right around 47% cross , and right around 50% left. Scott is right....get the car as light as poss. so you can add weight to the left side. Percentages vary between cars depending on corner weights. If you dont have much left side weight...you usually need less cross to get the car to turn. I get as much left as I can and usually the cross ends up somewhere between 45-49.

Thanks guys! Keep the info and ideas coming----VERY helpful. I have raced 10th scale for years, but i am new to this beast! I have already found out a few helpful things with the scales, for instance on my car one round on either rear shock changes the weight by almost exactly an ounce. I understand that tire temps are extremely important. But, any scale related info you can share will be greatly appreciated.
