........ there ....... you needed that ......

Now, go find out what's wrong with your car.

* tire pressure ..??

* EPS got messed up (as mentioned)

* alignment got messed up (as mentioned)

* you're just recovering from a hangover (ask @Cole )

* Bubba replaced the battery .. ??

Seriously, what else have you recently done to the car, except change the battery...??

Take a deep breath and relax.

Do you really think the a change in your lead/acid accumulator that has affected your "handling" to this degree?

Have you checked your tyre pressures?

I swapped it for a 26R-DL at autozone. It weighs about 28lbs.

I knew this thread would turn into a heckle show of who can and can't feel the weight difference in their car. I stick with the old equation of force = mass x acceleration.

I pretty much immediately knew there was a difference as soon as I took it on my favorite back road, which has a left corner that normally makes the front end of my car bump up twice, I take the corner on the battery with 15lbs more weight and the front end doesn't respond in nearly the same lively way. Then I tried taking the right corner at my apartment, which normally allows my car to do a quarter turn easily, instead the front right sunk right into to it like a stone, did not feel good.

Too tired now to go out an re-learn the throttle again and test this battery, but I'm satisfied that I've got a battery that weighs nearly the same as stock.

It's all in your head.

There are so many more variables that would make it feel different in the way you described.

Have you ever corner balanced a car? I can tell you right now that 15lbs isn't enough to upset it so much that you would feel it in that way.

Just drive your car and stop filling your own head with BS

No, but i have heard some stuff about corner balancing here, someone mentioned in a different thread how adding an OEM Audio+ sub in the rear perfected the corner balance, a 30lb difference or so.

If changing the battery destroys the handling in a car, then every time I fill up with gas the handling in my car (or any car) is completely destroyed!

What you describe is not a corner balance difference.

It sounds like a broken part in the suspension, uneven tire pressure, a whacked out alignment... Depending on what it is, it could be dangerous, but it's not from a 20lb corner weight change.

Really? You truly believe this? You are normally a pretty bright guy but man you went to the darkside on this one. There is not a hope in hell that 10 pounds had any effect on the steering of the car. None.
