metric monte carlo with 1200 rf, 1000 lf, 200 rr, 225 lr. 1/2 mile medium to high bank track. car will fly down the straits but the rear end just wants to swing out and slide in the turns. The car just is all sideways threw the whole turn and look really cool but we all know this is not the fastest way around the track when everyone else can drive threw the turns. So basically it really loose is what I am tring to say. Put the car on scales and found out we only have 44 % rear. Could this be the problem. If so the car will be on major diet soon. Just looking at suggestion , Will a car work with so little rear weight?

I know you are asking that just joking. Get some weight in that puppy in the rear. Have a good one

44% ain't near enough........

If you can't work em in close & git em in your face with their orange landing gear down, don't bother taking the safety off......

I run 44% on the front. You may not need 56 or more rear, but you need alot more than 44.

Thanks I am trying to get the car down on weight a little. Are yall getting 50% plus with the engine in stock location. Also is it worth it to run a little heavy to acheive good rear %

I would have to say yes its better to have more rear weight. We had like 45.6 at one time and we added weight and we are up too 48.7 and its really beginning to show on the track and we are 450lbs heavier than most we run against.

Running super light doesent do you any good if there is no rear weight.

What are some of yalls metics weighting in at I am down to 2950 with out driver. If I cut out floor pan and enclose car would It shave any weight. I need to weight 3100 with a good rear % with engine in stock location 44 % aint working and if i figured it out right it would take several hundred pounds to get up to 50 %

If I strip all the lead out of mine its right at 3000 with me in it. But, I have the trunk gutted out. Mine with no lead is around 48%. with 300 right above the rearend and 150 between the rearend and fuelcell(12gal) its 54.4 at 3450(min wieght). When it gets real slick I run it up to 57 at 3600 with all of the lead ahead of the gas cap. usually around 230# of left rear. If your that low on rearweight I wouldnt be afraid to hang 200# right on the rear bumper. Dont go much over that or the swing factor will come into play. In the pic you can see pretty much how mine is layed out. The cage and motorplacement are all by IMCA streetstock rules.

Soften your right front and stiffen your left rear.

Yes you may need more rear weight but remember .When you took the weight off you changed the front end settings also . Sounds weird but the front is not slipping enough to let the rear stay straight.Little less camber on both fronts may free it up .

If this is a Hobby Stock you need around 50-51%. Best way to get this is to lighten the front with a dodge caravan rear bumper on the front, aluminum radiator, aluminum pullies, short water pump( aluminum if rules allow), set your engine back 1 1/4 inches, cut the front fenders out as much as possible, gut the hood (get an aluminum hood if possible). Them changes alone will add 2% or more rear depending on what stuff you have on the front now..

We did most of that stuff to our hobby and gained 1.5% rear.
