The front pads wore down on my 2004 WRX, so I decided to take the opportunity to change all the pads and rotors. Seemed like a good idea...
I already had a spare set of Hawk HPS front pads, so I bought rear HPS pads and DBA 4000 series slotted/drilled rotors for front and back. The previous owner had put on TVR Racing big calipers on the front (they're red with silver lettering, and apparently are Brembo knockoffs if that helps). The rear ones are still stock. The front pads I had in my garage say they are designed for big Brembo calipers, so that makes a lot of sense.
Anyways, I had my neighbor (a mechanic of 30+ years) do the work for me. He put the pads on without any problem, but said the front and rear rotors are too small in diameter. So I tried to call back Fred Beans Parts (where I bought the stuff) for an exchange. The rotors they sent me are the correct stock size.
So, I'm assuming that the previous owner put larger rotors on there too and that's what threw off my neighbor. He said it looked like I had rotors designed for 15 inch wheels instead of 16 inchers. I'm assuming the ones that are on there are actually for 17s rather than 16s.
They are plenty willing to exchange the rotors for me, but neither them nor I know what size would be the proper replacement. I guess I could just put the smaller ones on there, but I'd hate to downgrade (plus, that's probably not going to work with the bigger front calipers).
Please correct me if I'm wrong on any of this stuff. I took some pics of my wheels/brakes. I don't have time to take the wheels off right now, but if you can't tell with them on, I understand and I'll try to get pics of them off later.
What size rotors do I have/need? Are these just STI sized rotors/calipers or what? Thanks in advance for your help, and please excuse me if I'm way off base on something. I'll try to provide more details if you need them.
Here's the rotors I bought: Link
Again, I know it's probably hard to tell with the wheels on. If need be, I will try and get shots with them off.
