Lowered Car, Losing traction while getting off drive ways - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

86_ZN6 · 10-24-2012, 02:05 PM

I just lowered my car with coilovers. minimal 35mm drop and im having a hard time getting off my driveway

I take the wide sharp angle every time, the bumper clears the drive way but once i go further something else hits the ground i dont know what it is and i loose traction.

car shakes a bit, traction control lights come on, rear wheels just spins.

has anyone experienced this?

i had lower cars in the past and i didn't have this issue.

just wondering what it could be

Check under the car for scarring/scratching.

hmmm, I had mine lowered on an Eibach Sportline and got no issues so far ... the ride is stiffer though.

Sounds like you're unloading one of your rear wheels. This car has a torsen limited slip differential -- if one wheel loses traction completely (i.e., gets lifted into the air), the LSD will not be able to direct torque to the wheel with traction. Just the way torsens work.

Get a buddy to watch from the outside and see what's causing your rear tire to lift off the ground.

Next time it happens, shift into neutral, pull the e-brake, get out, and look. You may be getting one wheel up enough to break traction with the ground (which would screw with everything).

Getting out and looking will be your best bet.

it's definitely coming from the front.

it doesn't sounds like metal so that's good.

sound like plastic scratching

i will check this out once car returns from corner weight balancing and alignment

makes sense

forgot to mention my right side rear is lower than the other 3 sides. can this cause the issue of it putting the load to one side and lifting the other side?

Anything rubbing in the front shouldn't cause you to lose traction in the rear. Sounds like you may have 2 things going on.

The rubbing in the front could be from the tire rubbing against the fender liner...check that for marking/burning (or check that as well if you get out and look when you hear it).

Does it only happen if you back out? Or does it happen when you pull in as well? What about if you back in/pull out?

3 wheeling?

It might, depending on how much suspension travel you have, how stiff the suspension is, and the angle....might tripod.

ah ok thanks. yeah corner weight balancing should correct all for side then

lets see what happens

only happens when im pulling out of my driveway.

no problems going back in

CaptainSlow · 10-24-2012, 02:32 PM

Do you turn one specific direction to get out? Like, happen to always turn right? Doing that, you may be compressing the front left, pushing it up into the wheel arch (rubbing on the liner), or possibly scraping the bumper. That could lift up that rear right wheel (since it's already up higher) enough to trick the sensor/lose traction.

when i exit the drive way. the street is sloping down

i only exit and angle to the left since there is always a car parked to the right. so in effect i am exiting to the left and going up the slope

i havent tried exiting to the right
