Past experience. They're really quiet (unless they're crazy hot), have really good fade resistance, and good linear bite regardless of temperature. Price is also really hard to top for performance pads.
Is this your first time buying from this brand? Did you consider other brands?
No, I've run them on my tc and my old mr2. Not really, I'm pretty dead set on these pads.
Was it easy to install? Any installation tips that will help others?
Like any other brake job.
Once you've had a chance to use the product, did it meet your expectations?
