subaru wrx brakes
 

I got offered a complete set of subaru wrx dual piston brake setup for $100.
wondering if I can use these calipers with stock civic 10.5" rotors, and hubs. the are in excellent condition.
the thing is that I want to upgrade my brakes to something better, but the only options I see big brakes all over, I don't want big brakes. I run 13" lenzo wheels for my 24.5" slicks, and 15" for my winter tire, and 16" daily. so I can't get big brakes.
any options out there for a drag racer?
will the subaru brakes work?

yeah, they should bolt right up since they're both japanese :1

damn noobs, stick to bashing afc and fmu questions


anyway, find out the thickness of the wrx rotor and then the thickness of your civic rotor. if they are the same or really close it shouldnt be a problem with a simple caliper bracket. also, if they are close and you dont want to make a bracket then sell them to me for $100 and i will put them on my car. lol

Re: subaru wrx brakes
 

Sounds like an awful lot of trouble to not change the size of the rotor. You will gain some surface area thru the bigger pads but wouldnt be a hell of alot cheaper/easier just to buy a GREAT set of pads for similar money and performance?

Re: subaru wrx brakes
 

pads arent gonna help anything if its not clamping hard. I have the cross drill and slotted with axxis pads, not much of difference from stock.
I need something that clamps and do its job without going with some 12" rotors, I need to be able to run 13? rims

Re: subaru wrx brakes
 

Other than more surface area, you also get multiple pistons which let's you modulate the preassure better. One big piston gives more of an on/off feel to the brakes where having 2 pistons with the same surface area let's you get closer to locking the wheels without acctually locking them

Re: subaru wrx brakes
 

the subaru calipers have dual pistons, and looking at them side to side next to my stock caliper they looks like they will work, I barrowed one from my friend so tomarow I will test to see if it will bolt up, if it requires a bigger rotor it should not be more than 11". if it works I will post some pics.

you have drums or discs in the back?

Re: subaru wrx brakes
 

integra disc conversion

Re: subaru wrx brakes
 

My stock std brakes work amazingly well.

If the car is auto-x'd whats the point ?

Mine dont even seem to fade at all, I made about 5 or 6 pulls the other night with hard braking.

But they might look pretty damn cool.

Re: subaru wrx brakes
 

front rotors are 22mm thick

rear rotors are 10mm thick

brakes are the same as plain jane impreznoid

Re: subaru wrx brakes
 

Changing to 2 piston calipers won't do much for fading other than them being bigger and soaking up some heat. Its all about the modulation. Even if your brakes feel good, if you swap to an ITR master cylinder and dual piston calipers, you will notice a big difference.

Re: subaru wrx brakes
 

I have everything you just mentioned. its just not enough brake for the driving I do.
the track here is so short there is not enough time to stop without killing the brakes, trying to stop from 125mph I brakes are usually red hot after one 1/4 mile pass. cross drilled rotors are garbage I changed them too often because they crack accross the holes.

anyways I tested the wrx calipers, and they almost fit, only 1 mm off they would work if I drill the caliper holes bigger they will bolt to the civic bracket, but they won't work using the wrx brackets.
so to listen to what philstubbs said I will not bother with this setup, if I run any faster this year I will get a chute installed.

somehow I didn't notice that you were only drag racing. For you to stop better you will need bigger rotors. Multiple pistons are more for road racing/auto-x
