Regarding brakes
 

If I were to install this would it void my warranty?

Toyota wouldn't warranty any issue with those components (or likely the whole braking system), but if you mean would it affect a warranty claim about something in the drivetrain (engine/trans/etc)?

Of course not.

I figured it wouldn't for those but maybe my suspension? Pretty much Ive never owned a new car so not entirely sure how these warranties work.

The first question you should be asking is, "Do I need this?" What are you trying to accomplish with your brakes? Are your discs worn out? If not, the discs in that kit aren't going to do much for you. If you're looking for a different feel, pads, lines, and fluid would be a less expensive and superior choice. Check out my brake upgrade guide.

Always a smart guy to listen to.

100% agreed with JRitt. The stoptech kit isn't a good way to spend that money.

Stop (or good quality blank) rotors are all you need, and there are better pads out there for similar money.

Stainless lines don't improve performance at all, just make the pedal stiffer.

And this is why I love this forum haha. Thanks guys!

Regarding warranty, I spoke with the service dept at the dealer yesterday and they said that any system unrelated to the aftermarket parts would still be covered. And they would would cover related parts if it is clear the aftermarket parts were not the direct cause of the failure.
