Here's the deal: I recently got some 19x9frt and 19x10rr with 245/35 and 275/35. I had them put on a week ago. No issues. Today, I had my TEIN coilovers installed (approx =1.5frt and 1rr). All was good until I was coming off the off ramp of the interstate (taking a right). The car was in neutral and I pressed the brakes. I could feel the brakes grab and make a noise more than they should and the VDC light started flashing. I got worried. Being curious I did the same thing on an off ramp to the left same issue occured. What's the deal!?!?!? Has this happened to anyone else with the same setup? Did I lower my car too much? I haven't got my car aligned yet. Is that why? If i go through the corner with the car in gear, i have no VDC issues. Imma get the car aligned tomorrow, but I am curious if anyone has the same problem. This didn't happen before I had my car dropped. Any suggestions or comments will be appreciated!!!!

strange, i'm at 1.3% bigger than the oem diameter with my 18" wheels and tire combo, no issues like your describing..........if anything, sounds like something wasn't installed properly(obviously), and not a vdc issue.......not much an answer, sorry.

unplug the negative cable and leave it off overnight, it should solve the problem.

I think your wheel combo & setup is ok. Your computer is noticing a rotational difference, which is exgerated, when turning. Outside wheels are traveling further than the inside wheels, as you turn. Also when you BRAKE & turn your ABS(can't be turned of unless you pull the fuse) is easily activated. Since you now have new "paramaters"(tire sizes), try resetting your computer as bk suggested. This should help.

Note that you'll need to reset your radio stations too!

OK. Negative terminal of the battery is disconnect. We'll see what happens tomorrow. Thanks for the responses. If anyone else thinks of something else, don't hesitate to post.

Damm that sucks, wheel setup and perfectly fine, shouldnt have one problem with it! If that negative cable disconnect works, wow LOL!!

It sounds like your alginment. By lowering 1.5" w.o. redoing alignemnt ... you now have quite a bit of 'toe-out' front and rear, which translates to darty handling under heavy braking and the tendency to oversteer when cornering. VDC was simply trying to keep the car in line under those conditions. Depending on your car handling skill, you might have spun out w.o. VDC.

Get it re-aligned ... and youi should be fine. Let's us know how it works out.

Well, the disconnecting the battery method didn't work. I'm going to get my car aligned today (as soon as I can get off work). I'm sure that my alignment in general is way off. To aim the car on a straight path, the steering wheel is approx 3 to 5 degrees to the right. I got the car over 60 this morning and it felt very unstable. When I was at the shop, we "eye-balled" the rear toe (i used the SPC toe bolts). So again, after work, I'm heading straight to the alignment shop. The only reason it wasn't aligned yesterday was because the coilover install was complete at 330 and most of the alignment shops couldn't fit me in before 5.

sometime by changing wheels offset,brake kit,lowering and such will change the way the VDC sensor reads.where are you live?

GOOD NEWS!!! (I hope) I got my car aligned this morning. Check out the results:

Front Left - (Actual/Before)
Camber - (-2.1*/-2.0*)
Caster - (8.3/8.3)
Toe - (0.04/-0.97*)

Front Right - (Actual/Before)
Camber - (-0.6*/-0.5*)
Caster - (3.5*/3.5*)
Toe - (0.06/0.08*)

Rear Left - (Actual/Before)
Camber - (-1.4/-1.7)
Toe - (0.10/-1.04*)

Rear Right - (Actual/Before)
Camber - (-1.0/-2.0*)
Toe - (0.10/-0.97*)

The camber on the front left wheel is outta spec and also are the caster reading for both the front. And I noticed that the front left corner is about 1/2 to 3/4 of an inch lower, so hopefully my camber will come within spec once I correct the ride height.

The ride has improved a great deal. And for my ABS/VDC issue, there is none (so far). I approached a couple of the off ramps from yesterday, and no VDC problems. It was raining here all day so I did go through the turn about 10 to 15 mph slower. Once it clears up, I'll double check.

So to conclude: Get those tires aligned to prevent some VDC issue. Thanks to all for you suggestion.

Yup ... wayy too much toe-out as expected at all corners but one.

I'm glad you were able to get it addressed.

It would have been a good idea to set the desired ride height at all four corners before attempting the re-alignment. You'll need to re-align your front again when and if you decide to equalize the front ride height by either raising the LF or lowering the RF to match.

Remember the following ...

Raising induces toe-in
Lowering induces toe-out
