Weight Distribution - How to do perfectly?
#91
I didnt know they made different threads that was good thinking. I run Afco double adjustables on 3 corners boy are those things a nightmare to figure out, but worth it in the long run. Its a good thing my friend has a dyno.

aaron you are right about putting one round in changing ride height.but yo only ajusted one spring absolutely it will change.the point i was making is that to properly balance the car r/c not real race cars you need to do things evenly(slight tweek on one is ok to balance perfectly is ok).even turns in and out on opposite corners will balance the wheel weights WITHOUT changing the ride height.this only works if your ride is set properly before you start.try it and see for yourself it will work.this is the easiest way for someone to do it especially someone with no prevoius experience working on race cars.on a touring car you want balance not wedge that is why it works.besides the fact for those that dont know oval cars run different tire diameters and ride heights on all four corners,plus wedge to get the car to turn in the corners.this is not what you want in a t/c.imo

When you move weight around to balance the car, do you take into account the weight of some of the suspension components?for example, some install heavy aluminum c-hub carriers and even alum uprights.
If I had aluminum c-hubs in front and all-plastic parts at the rear, on the scales (or when the car issuspended on a string) the car might appear balanced but the actual sprung weight is not.
So do I remove all un-sprung weights befor balancing the chassis?
Thanks

weigh your car and balance your car just as you would race it otherwise everything will change.

Has anyone tried these scales?

Pretty cheap and if they works, it might save you some money.

guys just buy the integy weight system its only 80 dollars ,i did the postal scale thing its to big and shuts off half way through.all you need is your setup board and the integy unit.this way you can bring it with you to the track.plus if you look on ebay there is almost always one on there for about 60 dollars ,i assume because they come with no real directions and the guys couldnt figure out how to use it properly.just my 2 cents.

I dunno, perhaps I'm, as you say, one of those people who doesn't know how to use the Integy system, but I think 4 scales would be easier in the long run... maybe not, but I'd like to give it a try.

cartman,
if you do it like i described in my previous post,even turns out on the heavy wheels(usually left rear and right front)and even turns in on the light wheels it works just fine,no need for a 4 scale setup.also turns out on heavy wheels adds weight to the light ones but will change your ride height if only done on two corners.also only doing one or two corners will not balance the wheel weights which is what you are trying to do.when properly balanced you will wind up with wheel weights of about 310-320grams approximately on all the wheels.slightly lighter or heavier front or rear depending on the car.just depends on what you like.also may be heavier if your car is heavy.what you want is both wheels on one end to be balanced and both ends to be close in weight.this will give you a neutral car,it wont push or be too loose as long as you have the right setup plus it repeatable every time.if the setup and wheel weights are the same the car will be the same as long as nothing else has changed diff setting,etc.everybodies cars i have done like this couldnt believe the difference in their cars from what they thought was a good car.

This thread's definitely one of the juicier ones in a long time... I think the last one's "Faster Cornering Like Pro"
I'm going back through the entire thread but please, somebody explain the wedge thing are you referring to the shock body threads?

wedge
wedge is when you purposely put more weight on two diagonal wheels usually alot more.this only works in oval car as it helps them turn one direction only.you DO NOT want this in a touring car the more balanced the wheel weights are the more neutral and easier to drive the car will be even if you miss the setup slightly.also the car will feel the same when turning left or right -no surprises!

re : Wedge
So if I have an oval car and track runs Counter clockwise... I only turn left for the entire time...
what are the diagonal tires I'm interested in? Front right - Rear left ???? or Front Left - Rear Right tires???
what does do these tires do that makes them special?

And again, I'm probably missing your point.... 'cause I can be thick like that.

weight distribution
cartmen 34,
actually you didnt miss my point,but once you do it a few times you pretty much know how many turns youll need to go.as ive found all tc3 s anyways to be about the same and i cant see any reason to spend twice as much money or more for something that isnt as accurate.i have two small postal scales they arent as accurate at the lower end of the scales readings as it isnt really important for their intended use unlike our.
rough512,
actually they are all important but usually the right front and left rear will be heavier .the left front doesnt really do squat so to speak-ever watch a well setup outlaw car or dirt modified its hardly ever on the ground coming off a corner.this is because most of the weight gets transfered to the right rear .i actually lost a wheel in a nitro trophy race and finished with three for the last minute or so and it wasnt really noticable under power or when turning with the one left ,turning to the side without the tire was a whole nother story.still finished second!

The only time I could see puuposly putting wedge into a TC would be if the road course only had one or two of one type of corner (left or right). For this discussion I thought we were talking about perfect balance, implying 25% of the weight on each corner...as the post title indicates.
I probably decided to jump into the middle of a conversation without reading all the posts....it's so easy to do in these massive posts that are on this board!
