Car losing traction in corners

Yeah just to let you know, if you have aftermarket wheels and tires then your sport mode or trac mode doesn't work the same as with stock wheels and tires.

So...do you mean turning it off will help or it wont help? (possiblby)

5sec TC=VSC off partially (it still can engage if it detects wheel hop or other complete loss of traction for one wheel). EBS also is still on, when one heavy brakes. Though then again, unless on track, i suggest drive on public roads with at least VSC=on always. It should leave enough slack for correction at most sudden unexpected situations on public roads (i learned it expensive way ). On track - if you don't push much, this may do.
Only pedal dance disables VSC/TC & EBS completely, leaving only basic ABS on from all the nannies. Will remove any unexpected nanny intervention, but don't be too overconfident.

I mean it just won't trigger if you turn it off by holding it for 5 sec. You won't lose control all crazy if you drive with it off, not like our cars make a monster amount of torque.

it is the wire in the clips. make sure it's not caught on anything and in good condition.

Sport mode disables traction control, the 5-second disable turns off Traction and Stability control. Pedal dance isn't necessary, I never need it even for seriously competitive Auto-x, and even with running 18's previously on just springs similar to his situation (but better springs).

Right now I think the best solution is for him to ride along in someone elses car or someone ride along with him to find the problem.

Followup:

Thursday, with TC/VSC off and no pedal dance, I put my car through several hundred safe miles of testing on wet curvy roads.

On 2 corners, during what seemed to be right rear wheel hop / lift /+plus sight roll, I believe (what some call) "ice mode” occurred, causing TC/VSC to engage.

After that, for some strange reason , the roll was no longer there == Yay!!!

I then attempted to reproduce the same results, ...and no matter how hard I tried; including going over the same corners where "ice mode” appeared to engage before, ...nothing happened, and the slight roll was still gone.

Friday (during rain) I returned to the place where I first experienced this minor roll, everything was still good, it (roll) did not manifest, so I continued researching and found the following:

well, ABS Ice Mode finally got me...

"Ice Mode" …specifically this post:

and am considering what CSG_Mike says here:

Ice mode is 100% driver error. Regardless of what they say, it is, absolutely, 100% driver error. I can replicate ice mode AT WILL, and if you are inducing ice mode, you're doing it wrong.

I have told this story before:
I ran into a guy at the track with a BRZ.
He had the fastest lap times of almost any BRZ/FRS in the area.
At every race, he said, that all the other twins drivers would come over and ask "what did you do to this car to make it so fast?!?"

He said "NOTHING!" - "Take all that aftermarket shit off your car and learn how to drive it the way the engineers intended"
He had ZERO mods to the car other than wheels and race tires.

If you have only driven your car on the street then you have NO BUSINESS modifying the suspension because there is no way that you "know" what the car needs.
Unless of course you are a "torretto wanabe" and drive like F&F on the street on a daily basis.

In my first 20 minutes on a real track, I learned more about driving that the other 30 years of experience doing what I THOUGHT was "driving" while on the street.

justatroll: i'm 99% sure that he also did alignment in addition to wheels/tires.

Yeah if you do any track driving I would say save your stock suspension if you already lowered it with something else chances are you will go back to stock and re learn the car and re evaluate what you want vs what you need. But if you mostly do street driving then keeping the rear within factory spec and 0 toe with a little camber won't hurt up front. You can lower it but just make sure you have the supporting items to get it within spec.

Agreed, All I have done so far is TRD lowering springs. I only have had one HPDE so next one I can build from here.

I don't have issues with the Ice Mode even while autocrossing... So I'm not sure whats going on with everyone else.

The BEST handling my car has been so far was when I only had 4 mods:

Front Strano Swaybar
Front camber bolts
BRZ front springs matched with FRS rear springs
Rear subframe bushings

That was it, even with the stock tires the car handled great and I had a ton of fun driving it. I tried other wheels/tires with this setup, and it was still good.

But then of course I wanted to lower the car and things changed completely, and I've been trying to get it back to that point ever since :P
