ITS DE5 Warped Rear Brakes 10K Miles

[dockleryxk]

So your saying the rear brakes should last 100k miles?

hahaha at least!!!

Yeah those days are over. Rear drums on a small car used to last forever partly because they were enclosed and not exposed to the elements, and now that brake TC is a thing I guess we're never getting that back.

Get like me bro this was at ~12k miles

For real though, are you that hard on tires? Because if so, you’ve got about 3k miles left.

There’s a guy local to me that changes the front tires on his FK8 every 5k miles. That’s crazy, but equally as crazy as expecting over 20k miles from the OE tires if you’re driving them hard at all.

What are you doing differently? I'm not a tire expert, but this to me looks like normal wear, but WAY more than I'd expect at 12k miles. This is worse than my 911 was at that time. This car doesn't have an engineering excuse like a 911 does, it shares its underpinnings with a Honda Civic. So a couple pictures from one dude on a forum isn't really helpful in setting expectations that I should set aside $2k every year for new tires and brakes. (that said I'm switching to 200 TW tires next year and use all-seasons half the year so this whole conversation is probably moot but I'm still curious)

TL;DR- How often, how long, what kind of sustained pace, and what public roads are you driving on that lead to this? And obviously disclose any suspension mods.

Relative to this, I guess I'm not that hard on tires. Outside of the autocross and the one track day, I admit I don't go on the type of balls-to-the-wall mountain or canyon blasts that apparently some people do. At least not like this... the OUTSIDE shoulders of my tires are all sorts of fucked, but last time I checked the tread depth was fine. I'll take pictures and measurements when I get the summers off, hopefully this weekend.

Unless something has changed dramatically in the past few years, I am still firmly in the camp that no one should reasonably expect to blow through tires and brakes in the first 15k miles unless there are extenuating circumstances. I am curious to find out exactly what those circumstances have to be to see results like this picture. Brake vectoring shouldn't be this substantial unless there's a reason for it... and what I'm most curious about is just how intrusive the brake vectoring is during mostly street driving.

But anecdotally, the main reason for my pushback here is the last car I did have for longer than a year on the OEM tires was an F82 M4, on Pilot Super Sports. As we all know, those tires were superseded by the PS4S, and they lasted me over 30k miles- but I admit the only spirited driving that car ever saw was half of a track day. Brakes were replaced after that track day because the factory steel brakes on the F82 were trash and the pad material did not stand up to even my novice track driving... but they were replaced under warranty and still had plenty of pad left.

You guys really must be pushing the car Transporter-style to go through wear items like this.

I'll respond inline so it's clear. I'll also omit things that I find irrelevant:

I never turned traction control down or off until a few weeks ago. I'm going to start doing this more and perhaps it will help (with the rear pads, not the tires lol)

This is worse than my 911 was at that time. This car doesn't have an engineering excuse like a 911 does, it shares its underpinnings with a Honda Civic.

Does it not? Creating such a capable FWD platform seems like an engineering excuse. We are asking a LOT of the front tires – more braking force, more stress from being the driving wheels, and spinning the wheels through 2nd for fun.

I have already been doing this – summer tires in the warm and all seasons the rest of the year. The 12k I said early was approximate because I didn't use those tires over last winter.

I'm actually switching back to all seasons today with some new G025s, look out for that.

TL;DR- How often, how long, what kind of sustained pace, and what public roads are you driving on that lead to this? And obviously disclose any suspension mods.

I live 40 minutes from the tail of the dragon and go up at least every other week in the warm, less in winter.

I didn't have any suspension mods when I took that picture of the tire but now I have these: Spoon rigid collars // Eibach PRO-KIT lowering springs // RV6 rear sway bar, end links, and control arms .

TL;DRs should be at the bottom btw lol.

I'd think AutoX and tracking would take your tires out more. I don't go balls-to-the-wall on public roads. I do go fast, but I leave plenty of room for error.

At least not like this... the OUTSIDE shoulders of my tires are all sorts of fucked, but last time I checked the tread depth was fine. I'll take pictures and measurements when I get the summers off, hopefully this weekend.

I can measure my summers later if you're curious. I bought some cheap 2021 Bridgestones on clearance from Tire Rack, and they might be my favorite

There's a distinction here IMO: OE tires are usually much worse. They aren't the same as buying the same tires aftermarket. They are optimized for the stat sheet and not the driving.

Try taking a corner a little too fast with traction control fully on – you'll hear it and feel it. Don't be scared, the car will save you lol

I do and I know for a fact @Car00071 does too.

If you lived through the early days of front wheel drive you'll remember how quickly it ate tires. Suspensions and tire compounds improved over the decades to make it a non-issue, but boost power into the mid-hundreds and add low-tw tires and the old problems come back. FWD will always be the weakest link.
