pads + rotors help

[MetalNeverDies]

is it bad to run sloted rotors up front and stock rotors in the rear with decent pads?

these are the ones im looking at

will they fit? does any one know anything about them or recommed a different brand or set?

i was also woundering about these but wasnt sure of the quality.

I have read that slotted rotors won't really do you much help over stock. They do look bitchin' though!

slits and holes share the same problem

this is from a gutted 911 turbo with brake cooling

ouch. that sucks

[MetalNeverDies]

sence the brakes on a 2.5i rs is different than the front brakes on the wrx would it hurt to buy front disks for the wrx and put them on my 2.5i? how would i get them to fit? do i need to buy a conversion kit of some type or what would i have to do?

well, if two parts are 'different', you typically can't interchange them ;)

seriously though, how are they different? I'm not familiar with your 2.5i rs.

What's wrong with aftermarket rotors for your model car? Yes, you would typically need to change the calipers to run different rotors, but who knows...call someone like Jamie Thomas (subie gal), she'll know.

Honestly, unless you're going to the track, keep the oem rotors and just upgrade your pads. just as good (For the street) and cheaper.



What are your rotors in the rear? Vented? WRX's have SOLID rear rotors (which suck) and yes, there's a kit to upgrade to vented rotors ('91 Legacy Turbo rear brake upgrade kit)

[MetalNeverDies]

i believe the rears are solid and the front are flat faced vented. i just figured if i could i would get the aftermarket ones like these for cheap and they would be a little bigger so they could help me stop faster. they are good brand and cheap too.

if they're fit...go for it. IF they'll fit.

if your rears are solid, you should look to upgrade those. Good upgrade, even just on the street.

would the upgrade on the rear brakes give me any more rear biased braking power or would it be strictly to help vent the heat?

So do you have the same brakes as the WRX?


If yes, then no....the upgrade won't add any rear braking bias since the rotor diameter is the same. They're just thicker (a lot thicker) so you need the different caliper.

The added cooling/heat dissipation will help with heavy braking since your pads in the rear won't fade as easily.

To give you an idea, its really hard for me to lock up my tires on dry pavement (a good thing). Some of it is that I've been running on my winter tires (haha), but the other side of it (imo), is that on really hard braking, if the rears stay clamped hard (and don't fade) that keeps momentum off the fronts (if that makes any sense).

part of it may also be the suspension, which keeps my car really level no matter how hard you brake, but especially on steep downhills, my car stops pretty quick. And for the record, I have cheap ebay slotted and cross drilled rotors that now have +40K miles on them :D

[me_jimmy]

i was thinking that if all 4 wheels can lock at any speed, they cant be better. why would it be good not to be able to lock up?
what kind of winter tires do you have, mine suck stuff i wouldn't even touch

well, I didn't say 'can't' lock up....but in general, I try to avoid locking up my brakes in any situation.

I've definitely slammed on the brakes a few times and *thought* they were going to lock up (and then start sliding into the car infront of me), but the car just hunkered down and the snow tires opened up their sipes and the car stopped pretty hard.

tires: Dunlop Winter sport 3D (the 17" ones are V-rated!)
great in the snow, great on the highway/dry, great on a rallyX course.

Slotted rotors do make a huge difference over stock. Drilled, well, pretty much stink..The holes just wind up getting hot and cracking, as in the pic.

The slots (and vents) help expel the hot gasses the pad is generating during hard braking. Also, since they are still closer to solid then drilled, they can take more heat (hard braking, lfb'ing). They are what we use on the majority of our clients' brake upgrades. No matter if it's a Leggy, GC8, WRX or STi, slotted rotors with better pads, stainless lines, and better fluid will help your braking tremendously.

Typically, we are using Powerslot, DBA, Racing Brake, or Stoptech rotors with Hawk, Ferodo, or PBR pads.

There are many options out there, so feel free to post, PM or email with any questions that you might have.
