Did you say 44 or 54?? Are you close to your target weight? If you are the front needs to go on a big diet.

what kind of car? It seems a lot of the guys on here are looking to get closer to 51-52% for rear I think thats why he asked about the 44%

Can you move your battery to the rear? Put it as far back right as you can to act as a lever. You'll only move what 40 lbs or so but with the lever effect it'll act like a bunch more than that.

i take it that you can't add any weight i'm in the same boat my car when i started scalilng has 48% before i even touched it here are a few options to help you out the battery in the trunk is one of them how big of a fuel cell do you run get at least a 22 and keep it full at all times another thing could it help to run taller springs or can you puit any shims in them at all thats what we had to do and it bumpeed it up to 52 just where i want it. and how bout a real heavy rear bumper and an aluminum front thats another option you might want to look into alot of stuff you can do we just need to know how far you can go acording to your rules

What does the car weigh and do you have a minimum weight where you race? Or are you stuck with the no added weight rule?

put taller front springs or shorter rear springs. try cutting some plywood donuts and stick them over your front springs and re-scale. You should see an increase in rear %.
If you dont you are out nothing money wise.
I think with that 53 cross you are going to push bad.

actully jeff not to hard to explain running differnet size springs is no different then putting shims in or useing weight jacks to change the ride to shift your weights where you want it. i was talking about the total scaling of the car not just the rear % next time i'll be most specific on which corner i was aiming for guess i did forget to mention the shims were for the cross

All the books say to shoot for 53 left 53 rear and 50 cross.
Then you adjust cross for your driving style and track configuration. Its hard to get that much rear in a stock chassis. So you can try extra cross to make up for it.
Just get as much rear as you can trying to keep your cross at 50. Then after you go to the track you will really know what you got.

Hiding weight is easy but not moveable. Use a 1/4 or 1/2 or 1" steel plate the size of the fuel cell and make you own sheet metal can. Maybe it isn't legal but know one will ever know.

One other option, if you are thinking of adding weirht is to put it in the frame rale. That why it can be made so that it could be removed. Just a suggestion.

did you strip out the fire wall there is alot of double layer in the window area that you can gut and hide with your dash also along the rocker panels is double layer too we always gut that out

Guys, changing spring height with shims will not change rearweight or leftside weight. It will only change the cross. The only way to change the rear or left weight is to actually move, add, or remove weight.

What do you have for bumpers? for the front try to find a light one. alot of IMCA guys are running late 80's or early 90's dodge caravan front bumpers on the front. they are aluminum and save alot of weight. what does the rear bumper look like? My old car was a 76 monte carlo and the rear bumper weighed 150-200 pounds. sometimes being a little heavy with the weight in the right place is better than really light with no rearweight.
