Default Brake and Rotors Upgrade Options???

Dear lawd, why is it so hard to find a good upgrade kit online?!

All I'm looking for are some decent replacements to the spongy shiet stock rotors and brake pads...

Non-drilled or slotted because lets face it... how fast are we really going in our Crosstreks right? but good enough to stop it fully loaded on a road trip with camping gear and occasional kayak...

Anyone have a good setup you want to share::

Always liked the Centric rotors and pads I bought for my WRX on Amazon. Not sure you'll get much difference in brake feel without upgrading the calipers and lines. Maybe a WRX swap?

Contrary to popular belief, drilled rotors don't improve performance. With today's advanced brake lining compounds, drilled rotors are primarily a cosmetic feature. Their original intended use was to vent out gases that were expelled during hard use. Almost all race cars now exclusively use blank (solid) or slotted rotors. Don't bother with drilled rotors unless you care more about how your car looks than you do stopping.

Brake pads, although do contribute to pedal feel, aren't the biggest contributing factors to a stiff pedal feel. Don't cheap out on brake pads. OEM are actually good pads, believe it or not. But if you drive hard, you gotta pay to play (think $150+ per axle set)




Sounds like you need to try out the master cylinder brace mod and stainless steel braided brake hose. Try those two modifications before you waste any money on brake pads you don't need.




And you clearly aren't aware that Crosstrek drivers like me actually exist...

I've gotten my brakes plenty hot on spirited drives. No, I don't ride the brakes, I actually drive hard on downhill mountain passes. I use full engine braking in combination with good use of the service brakes.

Just because these cars aren't WRX's, doesn't mean there aren't drivers that don't treat them like one... If you drive as hard as me, you MUST get pads that are capable of handling +1000 degree Fahrenheit temperatures. It is simply not safe to attempt any hard driving with premium service aftermarket or OEM grade pads, light track pads must be used at the very minimum. Full race/track pads may be used, but some (no, MANY) may and will be unsafe at colder brake temperatures.

So if you do intend to drive hard, high temperature brake fluid and high temperature brake pads must be run. DOT 3 brake fluid and brake pads only capable of up to 600-700 degrees Fahrenheit before overheating/glazing are unacceptable.
















So if you truly do wish to upgrade...
  • High temperature brake fluid (DOT 4 or 5.1; do NOT use DOT 5)
  • High temperature brake pads (1200 degrees Fahrenheit and higher recommended, avoid using pads with excessive minimum operating temperature)
  • Robust, high-quality brake rotors (DBA [Disc Brakes Australia] rotors are the only ones who make high performance rotors for our vehicles), stock OEM may suffice for milder drivers, aftermarket replacements not recommended (virtually all aftermarket replacement rotors are made in People's Republic of China, excluding some performance rotors).

AWDfreak is that a pic of you rotor glowing red? CRIPES... but all great points.

Good to know there is a company making quality XV rotors. I doubt you'd see XV support from Baer, Wilwood, Brembo, etc.

To add to your DOT fluid suggestion, change early and often. I think brake fluid might be the most neglected automotive maintenance in the world. I invested in the Motive Power Bleeder. Makes bleeding/changing fluid a breeze.

AWDfreak, DBA doesn't have rotors for the Crosstrek. At least that's what KNS Brakes told me.

Yes, those are indeed my brake rotors on my Subaru.

Before you conclude that, I would contact Disc Brakes Australia USA and check the following part numbers for XV Crosstrek compatibility

P/N 4650S front, 42663S-10 rear

The above part numbers should be brand new on the DBA catalog.

Was told that they don't fit for the rear's by KNS.

Just got off the phone, someone from DBA USA confirmed that the front 4650S and rear 42663-10 are designed to fit GP chassis XV Crosstrek models.

And it turns out blank (non-slotted, not drilled) rotors are special order items for DBA USA.

Great, I was just telling what I was told from KNS Brakes. He said they test fit them and they didn't fit. Give them a call? Maybe I miss understood him. If they do fit I'll be getting them on my pad change!!!

AWDfreak, got this email from KNS Brakes:
It's wrong because it does not fit your car.* DBA listed it incorrectly.
You are welcome to order it if you think it is correct but I won't accept a return when you attempt to install it and it does not fit.

Correct

650 and 4650 are the correct front rotors.

2663 and 42663 are listed for the rear but that is an incorrect listing.

Centric makes your rear rotor but it would have to be ordered as it's a newer and slow moving number.

I see that 42663 p/n. That's the BRZ and newer Legacy vented rear rotor which is incorrect.

You have the non-vented rear rotor shared w/ newer Impreza's.

It might be new/we have not updated yet.

Checking further now.

Fred

I show front rotors for that car since they are shared with older WRX applications but the rear is different and not make by DBA.

Are you interested in just fronts?
