Question Not sure how to describe the issue

The car recently got coilovers (BC BR). Not slammed, about 1 - 1.5 finger space all around (just under 1 inch of gap space).

When I was pulling the car onto my driveway at an angle, the car would not move when I pressed the accelerator. The VSC light was on at the same time. The front tire was on the driveway, but the rear tire was still on the street. I had to put the car in reverse and pulled out of my driveway. Drove it around the block and then pulled up to my driveway again and this time I didn't angle it as much. No issues this time around.

Not sure what went wrong. Any ideas?

Any chance you were bottomed out? Could the bottom of your car been against the concrete from the angle?

I've heard this being described before and it was on other lowered vehicles. It is common, and happens from what I've read. I've never had this happen myself (I'm lowered 2.5" on BCRs). It has to do with the geometry of the suspension and the Lexus sensors telling the car it is unstable.

the weight transfer put all the load on the inside wheel and the absence of load on the outside wheel "tricked" the traction control system to think that your 2is was experiencing low traction.

when that happens, the 2is traction control system will automatically cut power, meaning you won't be able to drive forward, no matter how hard/much you push the gas pedal down.

Could one combat this by turning off the traction control when it happens?

Anything I should worry about? Raise the car a bit?

Or was this just a rare occurrence and won't likely to happen again?

Thanks for all the input!!

nothing to worry about, but you'll face this every time you have to go up a steep-angled driveway from the street.
