I'm looking into a new rear suspension for my 69 Charger and knowing the weight percentage on the front is one piece of info I don't have the means of weighing. I figure you race guys might know this? Its a full street car likely close to stock as far as weight is concerned with a 400 iron head motor. Any suggestions on where I could find this info out or a tip on where one could have this done would be appreciated? Thanks
 
Your local cops might let you use their scales if you ask nice. They always have a set for spot checking truck weight. They might let you use them at their site. Just bring a jack so you can slide them under.
 
Happen to have a local stone distributor that sells retail? They sell stone by weight, so they weigh trucks before and after. Call them up and ask when a slow time would be. The only issue is you'll be washing your car after that visit lol.
 
So how would you suggest doing it with the truck scales? Picking a mid point in the car and trying to have 2 wheels on the scale stopping at midpoint? Total curb weight of the car only goes so far trying to figure out bias.

Lol, ya know, you're right, that was dumb. I guess i'm a little over worked and a little over tired...
 
I did a quick search couldn't find Canyon's posts on the subject but sent him a PM asking him to weigh in on this thread.

I also sent Dan Weishaar a message on FB
 
Nothing like having individual scales but in a pinch, you could go to the track (if capable) and weigh the front half of the car and then the back half. That will get you in the ball park at least for weight bias. Just mark the car in the middle and don't pass that point on the scale....

HEY HYRDGOON I did my race car with a professional setup for corner balance after I completed a new front end and new adjustable shocks. I have pics on my phone. I have yet to put them up on my computer. What is it you would like to know? I will answer any question if I know the answer.
 
May have a lead on someone I can borrow a set of scales from?

Canyon do you know your weight Bias? Percentage balance front to back?

thats with me in the car
 
Wow 48.7% to the rear that's almost dead even front to rear. I'm gonna assume aluminum block as well as a fair bit of other lightening up front? Heavier *** end too... Dana?
 
yes all fiberglass through the doors lexan side windows, al heads, al radiator, no interior just got a new driveshaft 18 lbs lighter yet to get it in. yes dana 60 and all strange engineering disk brakes. Before we did all this the car always wanted to go right so that's solved.

Of the B-Bodys I've had, they're usually 53-54% on the nose. Rear is usually 1500-1600lbs. A 125/130 lb/in spring is very close.

It's all about the hit. This works well for me but, its always about lining up straight.

Hope you're not thinking that a Dana weighs a couple of tons more than an 8 3/4 are ya :D. A lot of people think they are 100's lbs more but in reality, they average about 50 lbs more......

707, what kind of rpm are you turning?
 
Most truck stops, concrete, asphalt, gravel or weight stations on the highway just weight the front then rear
and if you want just put one tire on at a time for side to side
Around home the scales work even when closed so truckers can check there axle weights
to stay safe
 
Find someone you know or that knows someone with race scales {like Canyon showed}
that's the only rear accurate way to know exactly what the suspension is doing, weight to rear
& what each corners/tires footprint weight "actually is"...

good luck

there's probably some fab shops, maybe near you,
that may/will do it for you for a nominal fee too...
