Rotor Swap

[mfanatic325]

Anyone in the Bay Area willing to swap rear rotors? I just got my car back from service and here is the data they provided me:

L/F rotors measured @ 26.69mm
R/F rotors measured @ 26.60mm
Spec for replacement < 26.4mm

L/R rotors measured @ 19.75mm
R/R rotors measured @ 19.54mm
Spec for replacement < 18.4mm

So I'm close to getting new front rotors for free, but the rears will probably still take a while yet =/

My warranty ends next month and I was wondering if anyone has extended or later-expiring warranty and would like to help me get new rear rotors?
If your rear rotors are pretty low, we can do a swap, and by the time your warranty runs out, you'll probably get your free ones as well

I only have 2 more track days scheduled before the end of April, and I'm pretty certain I can wear out my fronts in time, but not my rears

go do some high speed braking

Let me measure my rears. I'm almost certain they're below spec or close to being below spec.

I'm not in the bay area though.

hahah probably still won't be enough to wear out the rears. The fronts took long enough, doubt the rears are as easy

Yeah, measure yours and lemme know if you'd be willing to swap. Where are you located exactly? Worst case we could ship the rotors to each other. USPS should be the cheapest as far as shipping rates go.

Let's hope your SA hasn't read the revised BMW NA Maintenance Program policy regarding "free" rotor replacement. In order to get rotors replaced under the revised policy the pad material must also be worn down to 3mm thickness or less.
Don't try and grind off pad material because it comes off in chunks. Don't ask me how I know
My front rotors are below minimum thickness as well as showing signs of cracking around the holes. I bit the bullet and ordered fresh front rotors from Tischer. Doesn't pay to neglect brakes when doing 15 to 20 track events per season. It's the cost of having fun

[mfanatic325]

haha we're going to try to pull the "customer reports juddering/excessive vibration under braking" trick lol.
And since it's shown on the service history that I just did brake pads and fluid flush, then the only questionable items left are the rotors

You know where they shoot all the pr0n?

[Nikki]

Yeah, my rotors are worn but the pads are not so they won't replace. Just be aware of that.

[cmark8]

Keep your old pads... And sand your rotors!!!

I just bought two spare sets of brake pads. You wanna borrow the thinner more worn-down ones? Then get your free rotors, and send me back the pads lol.

lol sand rotors? I've never heard of sanding rotors. Is it just like turning/machining/resurfacing them?

[cmark8]

do anything possible to wear out more right? machining it might help! hahaha!

But hey, I was always under the impression that cross-drilled and/or slotted rotors weren't turnable?

Turner is having a sale on rotors. Not sure what it nets to with shipping, but worth checking.

[mfanatic325]

Yeah I saw that. Definitely one route to go. Trying to get everything for free though

Just a reference for myself and anyone else:
Front rotors from Tischer BMW = $200 + shipping (each)
Rear rotors from Tischer BMW = $155 + shipping (each)

Turner fronts on sale = $500 + shipping (pair)
Turner rears on sale = $300 + shipping (pair)
Shipping to California for a set of four rotors = $83


edit: so it looks like Tischer is still the cheaper route altogether lolll

[r4gs]

^tischer's usually great with their prices and price-match if u ever found oem parts for cheaper.

[mfanatic325]

Yeah I usually get my OE stuff from Tischer, or at least have my local stealershits price-match with them

It's worth a shot - on my old Si coupe I popped the rear sensor at the track, the dealer replaced the pads but not the rotors since they weren't worn enough but on road testing they noted the judder from the pad deposits and replaced pads and rotors on that basis, tho neither were worn to the limits.

I might be able to help shuffle rotors - I'm in socal (not far from "the Hack"'s day care) and will be at NCRC on the 11th.

[mfanatic325]

Oh snap! Yeah lemme know if that's doable =]

[Finnegan]

There's also this idea from The Hack in case the plan for rotors doesn't pan out: http://www.racingbrake.com/BMW_p/D401-01-311.htm

T-hill with JD1PT and his buddy rocked today. I'll start a thread once I get some food in me (I was downloading what I learned today to the computer from my brain/log book just now). Long day. Short story is I learned a lot (great instructor) and was waaaaayyyyy smoother and faster my last two sessions. 'Kitty improved tremendously during the day as well. And most importantly we left the track happy and ready for more.

[mfanatic325]

NICE!
I really wanted to go, but no Z4M buddy to accompany me for the trip up

I'll be posting pics tomorrow, way to freakin tired to get off my ass tonight...Was watching u both from the second floor on ur last run. U both looked really good!

Lon I'd swap, but prob gonna have to do some slight of hand myself before warranty is up. Might do a pad swap with u later in the year if I still have lots left.

No prob. I just got a full new set of pads from the dealer, and ordered two used sets (one with ~30k+ miles, and one with ~ <10k miles). We can swap back and forth however fits our goals

When does your warranty expire? Just so I can gauge a timeline.
