Traction control overly sensitive after lowering

[Mk5Frank]

My car is dropped on Rsr coils, front caster bushings, have front and rear sway bars, front lower control arms, rear end links…. Drop is 1-1.2”

I am noticing lately the traction control is super sensitive.

even going on and off ramp at 40-50mph will set it off

my tires are ps4s 305, psi set to 35

in the canyons it is super sensitive where it’s actually more dangerous on that off so I take it off completely to carve.

anyone know what the deal is ? Someone said height leveler sensor but it was installed correctly back in and I have 0 error messages.

hi, you sure the all sensors are correctly installed? I guess the arms can be flipped 180 deg and be pointing the wrong way, but still look OK at a glance.
I did that on my 3 series bmw when I lowered it. Didn't notice it before it got dark and I saw my headlights were all over the sky, no errors there either.
Not sure if that helps but just a thought.

If you're lowered with SPL's Front LCA, you'll need to drill an extra hole in the 3d printed ride height bracket that came with it.

If your lights are pointed more downward than normal, that will also help with he issue, but you may also need to manually adjust them.

I would also check the rear ride height sensor and make sure it wasn't reinstalled in the wrong orientation. This will also cause your lights to point upward.

i have it in the correct orientation

can someone explain what this has to do with tcs though ?

The front bracket I have it in the second hole and you can tell it’s still not 100% in the original orientation, It doesn’t have that 90 degree angle that the stock bracket had

 

[Mk5Frank]

Took a shot of the rear, orientation and everything is plugged in correctly, 90 degree angle. Don’t think it’s my rear.

 

[Mk5Frank]

Took a shot of the front, it’s also plugged in, and installed correctly. Both are at 90 degrees

For me this happened after i went 275 squared on stock rims (19x9 and 19x10).

The problem was a combination of problems

* 275 on 9 inch front rim when max was 265 this made sidewall very soft
* tire pressure above 45psi in the canyons (ACH) due to altitude (36 psi at the bottom)
* not setting the TPMS tire setting to Other Tire (this by far affected the traction control the most)
* alignment slightly off (due to driving on a flat tire to the tire shop)

Its not this for me

Only thing I can think of is lower control arms is not set to the correct center roll angle

What is your current rear toe and rear camber?

What is your current rear toe and rear camber?

-2.5 in rear, toe is stock specs I’ll grab sheet but everything outside of camber is stock specs

You're right, the headlamp level sensors have nothing to do with traction control. That's just to level your headlamps.

 

[MYNEWFAST]

More than likely, your camber may have changed and you may be getting more inside tire traction or on the inside shoulder which is making it a little bit more squirrely.

Pour a cup of water in front of both rear tires and drive through it one complete Revolution and see what markings come out.
If the tire is flat with good tread, you're good.

If it's riding on the shoulders only, raise your air pressure.
Or reverse,, lower your air pressure if it's only showing the center tread.

Hi, having the same issue. How did you fix it?

 

[ChrisMK5]

I'm curious as well as to what your solution was. I'm currently going through this after getting new wheels and tires

How many spacers did you use with you FLCA?
