"safe" will depend on the tune, the tuner, and data logging. Little else matters. What exactly do you want people to say in this thread?

1000's are serious overkill. 650's would be just fine. had a similar setup and loved it.

Sounds like a good setup, but like Hinshaw said the tune is what makes it "safe"

That makes no sense at all. The brakes on the car are designed to handle the specifications of the car. He is not adding weight, at least a significant amount of weight, or larger wheels. So he is not increasing inertia. He will not have the gas pressed down while braking (I hope). He will be going staying within the speeds the car was designed for, just moving around in the area alot quicker.

Wouldnt u want the peace of mind knowing u can stop on a dime , quicker due to the weight argument u just threw at me.

How can you stop quicker? If you lock up the brakes its going to be the same no matter how big your brakes are. Its at that point the product of the friction between the tire and the road surface. Since you can lock your brakes up with either setup, its about finding the pressure point in which you can apply maximum pressure on the rotors without locking them up.

More pucks/more pad surface area just reduces the amount of pressure used to stop. Thus it also decreases the amount of pressure it takes to lock up the wheel.


Which brings me to a good point. If you do not already have quality tires, I suggest that as an upgrade. They help put the power down and all the other bull****, cornering and safety and whatnot.

I wouldn't be too worried. That turbo is a fairly modest upgrade. Have it leak down tested before installation. I've had my VF series turbo on for about 20k and about 15k of stage 2 prior. More worried about the clutch now at 80k. The engagement is getting a little sketchy and I think I'm getting some slop in the throw out. You can also alway go a little conservative with the tune. Tell the tuner what you are looking for.

Don't do it. Leave it stage 2. With that mileage, you will run into issue.

This is great. Go home, your not a physics major, you don't know what your talking about. Research before you speak

Doesn't matter how well you take care of it. It's like anything, the more it's used, the more likely it is to break. Honestly, if you really want more power, but a sti, or make yourself a project and do a hybrid build. Or get a completely new motor. There are a hundred different route you can go. But I opt to say, do not go last stage 2

Compression test first. If the numbers check out, go for it. It will give you peace of mind knowing the motor is healthy.

It's too much of a risk. Call any reputable tuning shop. They would not recommend what he wants at this mileage. If you have money for a rebuild, go for it. To me, you should call some tuners, get their input, and go from there. It's too risky

Your over simplifying the problem. Yes, stock brakes allow one panic stop. Of course, with a significantly more powerful car, higher speeds will be achieved faster and more consistently than with a less powerful car. Which means you need to think of fade.

Also, feel comes into play. Bigger brakes have a better feel to it (of course, fluid, stainless lines help as well), particularly with the Subaru 4 pot and H6 upgrade in the rear vs stock 02/03. Stock brakes on the early WRX's are absolutely terrible. I understand he has the 4 pots already, but maybe he would like the feel of larger brakes, which inspires more confidence, later braking, and faster times.

Telling people that they should increase power and never upgrade their braking system is simply illogical, not to mention dangerous. You want a balanced car, not one that can go 150 but the brakes fade while trying to stop once. What level you upgrade to can be debated, but fluids, lines, pads should always be mandatory. Track days may require big brake kits, certainly on the WRX's they would.
