3.3TT WTF happened to my rotors? (Track Day)

[ElChanclo]

The Bluestuff has been through 3 track events and quite a few AutoXs so far. There was a visible amount of wear on the Bluestuff after the first full Track Day, so I thought they might wear out pretty fast. Since then, wear rate hasn't been as high as I originally thought.

If I can get a handful of track days out of them then it'll be worth it, considering street pads wear out after just 1 and I'd have to buy a new set anyway.

The 2.0T Stinger is due for brake fluid flush, as soon as this hellishly hot weather lets up a bit. I'll get a chance to pull the pads for a closer inspection.

Keep me posted on that, I'm curious if it's just my car, or common for stingers to have uneven pad wear 3 different ways. Do your stingers have the Brembo calipers?

I've also kept the ABS and TC nannies on so far. I'll experiment with disabling them once I get my track pads sorted, and learn to reduce tire squeal through the corners.

As much as we enjoy having fun on weekends. track time constitutes a very small % of miles driven. Most of the time/miles are on public roads, where I have zero interest in engaging in buffoonery...
Unless you become seriously competitive, does a few seconds faster/slower matter that much, realistically? I would concentrate on getting the rest of the car track-prepped properly.

That's where I decided to draw the line. Considering 95%+ of my driving is on public roads, I'm only making modifications that either don't negatively effect daily driving, or ones I can add and remove without too much time and effort.
At the end of the day it's still a 4000lb long wheelbase grand tourer. Time and money spent modifying it to be tack focused would be counter productive to it's GT purpose and would ultimately be better spent on a smaller & lighter coupe.

245/45R18 square would work too, although the sidewalls are gonna be quite a bit taller than your stock 19's.

More sidewall is what I'm looking for; a smoother ride on public roads. Though I have no idea what effect going from the stock 3.5" sidewall to 4.3" will have. Might be too much, or not enough to notice or be worth the hassle.

I had the idea of throwing a square tire setup on the staggered OEM rims (235/40r19 should fit both the 8.0 and 8.5 widths) and timing a tire rotation just right so you only have to do it once before the tires wear out.
I figure 245 would compromise steering too much at the front, while going down to 235 for the rear should still be ok with AWD.

Do your stingers have the Brembo calipers?

'19 Stinger came with single-piston calipers. I retrofitted Brembo calipers and larger rotors back in late 2020.

'23 Stinger is the Apex Edition, which has Brembos. Shock felt firmer than the '19 too, so they might have tweaked the dampers too.

Realistically, with the OEM staggered wheels, you cannot rotate the wheels front&rear, even if tires are the same size front and rear. Also, the same size tire mounted on an 8" wheel will be supported differently than on an 8.5" wheel. I don't think it's worth the effort to remove the tires from the rims, in order to rotate the tires... but that's up to you.

Its ur pads, not ur rotor. Either ur pads are defective or trapped lots dusts. if ur pads almost wear out, change them. if not, sand ur rotors(both sides w/ 300 grid) and clean ur pads well include sanding a bit.

Another possibility is that ur brake hardware was not installed properly and ur caliper is not compressing evenly.
