During my oil change yesterday, I adjusted my rear cambers to make it more negative because the top of the rear tires are hitting the fenders whenever I go over a bump, took hard turn, etc.. I have aftermarket SPL rear cambers. My fenders are rolled by the way.

Before, my tires was flush with the fenders, and since i only have lowering springs, it slight rubs when i got over bump, hard turn etc. See pic below:





So after i adjusted the cambers, the tires are slightly tuck in, barely clear the fender but not by much, but the weird thing is right away i noticed my handling had been affected. My steering wheel are slightly turn to the left now, not straight anymore. Also, whenever I accelerate, the steering wheel feels loose, kinda like i dont have any traction, but the SLIP light isn't blinking.. Also, from about 30mph accelerate to 50mph or 60mph, it feels like there are strong winds outside and my car has a slight swerve left and right. This doesn't happen when im just cruising and not get on the gas pedal.

So my question is, does negative camber give me less traction and going straight and make my car doesn't feel stable on the road?

My rear tires are 295/35/19 on the rear, front are 255/35/19.

 

yes it will

 

but i thought you get more traction with negative camber. I guess i'll adjust it to make it even later and see if it will improve my handling. But how come my steering wheel is slight turn to the left now instead of straight for normal driving? how did camber affected that?

 

Maybe adjusting the camber affected the toe somehow?

I just had an alignment done on my car after adding lowering springs. I was getting some similar issues to you prior to alignment, such as the "loose" feeling and being pushed around at hwy speeds just going straight.

Pre-alignment report showed my toe was extremely out of wack, after getting that brought back down to spec my car handles WAY better. My rear camber is -2.2 on a 275/35/19 for what its worth.

 

The answers is it depends on how much negative camber you are running, but if you are running the "stanced" huge camber setup, then yes you making your car handle worse. "Stanced" cars aren't setup to go fast.

 

The camber arm also changes toe, and the toe arm also changes camber , if you adjust one , you need to adjust the other.

Camber and traction. The more camber you have , the more traction you have while cornering. Then, you will have less traction on acceleration.

 

thanks Len. I'll bring it to the alignment shop to get it adjust later.

 

Did you have both rear tires in the air when you made the adjustment?

 

unfortunately no..did i messed up the toe too? The car was on a drive-on ramp lift because i was doing an oil change at a shop.

 

As long as it looks cool thats what counts. Handling is way overrated.

 

go to the alignment shop and get the camber where you want it (ie looks/ so tire doesnt rub) then get the toe aligned with in spec if you can. go into the bay and tell them where you want it, dont wait in the lobby and suggest things, physically stand over the techs shoulder, remember most of these guys suck at their job so play close attention to what is happening and read their print out before it comes off the rack.

 

actually i adjusted it so the tires wont hit my fenders when i go over bump, or hard turn. But i guess I have with it now since the offset on the wheel is low and the tire size are a little big. I could run 275 tires size and never have this issue in the beginning.

 

55 series on 19s? Those don't look like 55s, but that could very well be a huge issue if true.

 

its 35 on the rear. My bad, its a typo

 

You will probably have to visit an alignment shop like others mentioned; with the adjustment of your camber, you've also inherently tweaked the rear toe settings. Good luck!
