2015 brz track reliability??

[jesse2021]

good to hear!

Wheel studs are junk, car is sensitive to oiling (both temps and type of oil), the '13's can eat coils, pay attention to wheel bearings/hubs.

Honestly, it is all stuff that is pretty standard with any car that you are going to beat on.

With that said, I agree with Code Monkey that you are better served to do your own research.

I've got a 2014 with 75k miles and over 150 trackdays (and the same number of autox events). The cars are very reliable at the track. Basic maintenance is all you typically run into (fluids, brake rotors and pads, and wheel bearings).

I have a 2013, over 100 days on track events since 2017, other than consumables the only thing I've replaced is the left CV Axle twice. Still on OEM clutch....

I mean, consumables can be a pretty broad term. Some people (not me) consider wheels (not just tires), brake calipers, brake lines, and more to be 'consumables' if they're tracking sufficiently.

Of course those same people probably consider engines consumables too...

Yes, to all of the above being consumables and why I opted to stop beating on a 10k motor M3 and got a 3k motor 86... one of the two was/is eventually going to blow up with track use. Just boils down as always to how often you're going to the track if you'll see it in the life of the ownership of your car.
Is it likely to happen, no, but its something to consider and put money aside for. Brakes/tires/fluids are standard though for calculating a good baseline for a yearly track budget

My consumables have been tires, brake pads & rotors. Plus fluids, filters, plugs etc. as normal maintenance.

Engine, transmission, rear diff, clutch, T/O bearing are all original (as in, they were installed at the factory by Subaru)

They're indeed all consumable. It really depends on what you consider acceptable modes of failure, and if the failure may or may not be catastrophic.

I look for a balance between a true racecar interval, and a street car interval, backed by objective data collected (wear rates, temperatures seen, etc.).


Wheels are absolutely consumable if the brakes are getting hot, but if the brakes are getting hot enough to cause this, then the brakes are undersized. If the brakes are getting that hot, then you also cause other failures, such as bending knuckles, knocking wheel bearings out of round, etc.

Conversely, some folks are always needing to replace while others never need wheel bearings. The same folks needing wheel bearings will also tell you things like "i don't need a bbk cuz my brakes don't get that hot", "Don't bother balancing wheels, it's a track/race car", "Does the wheel balance? then run it. Bends don't matter", etc.


Ultimately it comes down to proactive vs reactive maintenace and replacement. For a casual trackday enthusiast, reactive is often the preferred method, because it's cheaper and more convenient. This often transitions to a proactive methodology as track attendance increases, as proactive maintenance is cheaper.


I maintain my car proactively. It's a large contributor to why my car never has any significant downtime, and doesn't suffer catastrophic failure. I don't want to find out what happens if I lose brakes at 140mph. Likewise, it's cheaper for me to sell my wheels lightly used with a low heat cycle count, in near-mint condition, rather than replacing them as they eventually bend from getting soft over use time.
