With a winged sprint car, to make weight rules you have to sometimes bolt weight onto the car. My question is, where do you put this weight that will help the car but also remain consistant

SprintRacer4,

ASCS rules mandate an area where weight can be added (you can find these on ASCSracing.com). I've not read the WOO or ASCoC rules lately, but I believe thay are probably in the same area. Generally speaking, the weight should be located as close to the rear tires as permissable, but there are a ba-zillion caveats that go with that. The weight should usually also be placed as low as possible so as to not affect the roll center of the car but, again, this has the same caveats.

What it boils down to taking your best guess as to the original weight location, then seeing what effects it has and adjusting from there. As the old saying goes, if this was easy everyone would be doing it.

If it is legal I would suggest removing the aluminum floor pan and replacing it with a steel one. I have done this before and it doesn`t seem to affect the car much if at all.

Steel Motor Plates work well, too.

I have built steel floor plans before, definitely going to be putting a steel motor plate in. Thoughts on filling the torque tube hoop with led?

I guess you could do that. How much weight are you trying to add ?

As of right now the car is about 40-50 lbs light, no titanium anywhere on car & about 3 gal. of fuel. We're running with a different series for a handful of shows the end of this yr & they're weight rule is quite a bit heavier then our previous organization so I'm trying to come up with the best way to add weight for these last 6-7 shows. Then over winter when car gets rebuilt we will add weight the right way

calculate your fuel usage that's an easy way to add wieght also try

steel stop's and get rid of the light weight bolt's steel is heavier and cheaper

Was trying to do it w/out just dumping fuel in the car, that's inconsistant & is an unctrolled variable. Changes throughout the night & constanly moving back & forth while racing, thus changing the handling of the car

When we ran Wing Cars and had to add weight, which was all the time since Coleman only weighed 120 pounds back then, we had great success putting "buck shot" or other small lead fill in the Rear Bumper and Left Side Nerf Bar. With a wing car, that left side weight also helped. Fill the Bumper and Nerf and then plug the tubes just past the area where you bolt them on. Works great. Good Luck
