I'd run the little battery up front until you need to run a kill switch. 50 lbs is alot of weight.

That 60 lbs in the trunk on a radial car will probably help it leave better.

It can, but usually with a proper suspension setup its not needed.

At what power level are you talking about?

Please show me a mid/high 10 second car
that runs a big drag radial, that absolutely NEEDS a battery in the back for weight transfer. I'm sure at the 600rwhp mark they NEED it in the back for the weight, but then again, they'd be in the 9's anyway and it would be required to pass tech.

Most guys who get serious about their cars and gut them for drag racing, end up taking WAY more weight out of the front than they do out of the back. And they also USUALLY end up ditching the 160lb 10-bolt and going with a 9-inch or a S60 or a 12-bolt, which adds at leats an additional 30-40lbs right on the tire.

If the car isn't dead hooking, takingthe weight of ths stock battery and putting it in the trunk will help. Doesn't matter how fast the car is.

I agree with you totally, but what i'm saying is that a car in the mid/high 10's that isn't required by tech to have the battery in the back will easily "dead hook" with some good tires and a few suspension pieces. Once the power level is wayyyy up there, then it is necessary.

I agree that anything can dead hook and leave at a mid 10 second power level is set up right, BUt unless the guy that's asking about moving the battery has moved the 60 lbs from the front to the back of the car and can actually say it slowed the car down it is a worth while thing to try for sure. I'd hedge my bets that it will allow the car to leave better. more static weight on the rear means less transfer is needed to get the car to hook, so the suspension should be able to be stiffened up a little, reducing the body "rock" onto the rear tires, meaning more foreward movement and less wasted energy.

That, plus the potential headaches from the little battery aren't worth it. I know "my car starts fine with it" and blah blah blah... but I guarintee the first time that little turd dies and leaves ya hanging you'll be hating life and wishing ya never bothered with it.

I did some more weight removal this winter and 90% of it was on the back end, I'm curious to see what it does to traction.

Been there and done that, you won't like what it did if you don't adjust for it.

You moved your CG forward is what you did.

Yup, and if the weight didn't come off the rear consistantly you will have changed the weight jack of the car throwing your swaybar settings off and may make the car leave and want to pull in one direction or another.

I hope you put the car on scales before and after, and measured your fender gaps on all 4 corners to make sure the car is sitting the same with the weight still distributed the same, if not get ready to start over.
