 Welcome! Before I start yapping about what this video is going to be about, I got to say this. If it's your first time here, you will notice that the rest of my videos are in a different language, which is Polish. So this is just kind of a test video. Decided to switch from Polish to English, see how many hits this video gets. After all, English is the most spoken language in the world. So for my Polish only viewers, sorry. Anyways, today we are going to work on this 06 Subaru WRX STI. Engine is stock. Stock turbo, 4-inch downpipe coming down to 3 inches. Then the axle back is 2.5. Short ram intake, wastegate solenoid, which provides super quick spool up. This thing is at full spool at about 2.5, even 2.4 RPMs. In third, fourth gear strut bar up top. As far as suspension goes, white line, solid sway bars from the back. There's also an H-brace. I will show that later under the engine cradle. And as far as brakes. And this is part of what we're going to be working on today. We're basically taking stuff apart. Steel braided brake lines. I don't know which brand. Hock HP Plus brake pads, which at this point are burnt. You can see they did turn white. Now I'm gonna put up a link on the video. If I find out how to do it or in the description below. Basically showing what happened. The front brakes caught fire or flames coming out during an open track day. You can check it out. It is something to see. But that video isn't Polish. If actually, if the other videos might interest you, let me know in the comments below. I may consider doing a voiceover in English, obviously. Also stands aluminum coil overs. Talking about brakes, you can see these are also, they got super hot. You can kind of see the reddish color on the rotor on the bottom there. And these pads gotta go. These are also HP Pluses. And the fluid. Brake fluid for sure boiled. That's gonna be replaced as well. So we're basically taking front and rear brakes apart. Checking out the calipers. If those are okay, replacing pads. I'm still debating on replacing the front rotors. The rears I'm gonna cut or rotate whatever you call it. The fronts, if I am gonna get new rotors, they're gonna be vented. Drilled. Maybe drilled. Most likely slotted. And we're also gonna take the suspension apart. And for sure replace the stands springs with some swifts which are softer. And I will explain why. Why I'm going soft. That's gonna be later in the video. And also we are going to take the rear diff out and check it out. Take it apart and see what's what. It is making noise on turns going forward and going backwards. I do have a used ATS carbonatic rear diff. Take the rear cover off. Basically check it out. Clean it up. And most likely change the gearing. This diff is from an O4 STI. And this is an O6. I believe the, although the final ratio, final drive is 390. I was told actually. I didn't know. I was told by a body of mine that the driveshaft is 1 to 1.1. And if I were to install this O4 diff on the O6, I would eventually blow up the center diff or something. Which would be bad and expensive news. So I'm gonna take those two apart. Compare the gears. See if there's any difference. I bet you there is. Anyways let's get to work. I didn't want to put on the lift. I want to keep the lift open in case something else comes in. And this is plenty good for what we got to do. Alright check this out. You got a little bit more work than anticipated. You can see the grease all over the control arm here. Looks like the axle boot ripped open. And grease started coming out. As the axle spins. So I'm gonna take the axle out and basically take it all apart. Clean it up. Put a new boot in. Rebuild it. A little bonus. Yay. So the left side. No major issues. Like you saw on the rear right side. Which is a bummer. Just a rotor. Wasn't easy to take off. But after some hammering it did come off. Mind you this is a 13 year old car. These were never taken off. It's getting hot in here. So now we gotta figure out a different way to take the diff out. You've noticed those long bolts holding the knuckle to the trailing arms. That did not budge at all. So I'm sure there's a different way.
