AU$503 including free domestic shipping.
i have a US forwarding address so it'll probably be maybe another AU$60-80 on top to get it shipped to me from my US address.

Well I emailed LPIRacing on Monday and still no reply... not a great start.
Can someone please clarify something for me.
Do I only need to purchase 1 of each item:
1 x Porterfield R4-S Front
1 x Porterfield R4-S Rear
1 x Brake Pad Wear Sensor Front
1 x Brake Pad Wear Sensor Rear
Or two of each? I'm not sure if they come in pairs or not. Please excuse the question as this is the first time I've ever purchased something like this for my car.
Cheers

So I finally had the chance to put these bad boys on, I still have the stock rotors btw. It has begun to squeak a whole lot which is rather annoying to say the least. I called the shop that installed it for me and they went ahead and checked the pads for me, everything looked fine. They said the reason it could be squeaking is because I put new pads on used rotors so the surfaces wont be even on both the pads and rotors, is this true? Compared to if I put new rotors and new pads together it wouldnt make any sounds. ANyone else have this issue? Worst comes to worst, they said after driving it for awhile if it still happens, they will have to shave off the uneven sides of the pads for me.. Im thinking of just driving a bit more and see if it goes away.

Crazy how easy it is to change the pads on this car. I've put new pads on 6-7 different kinds of cars and this one is easiest by far. My independent shop quoted ~$900 to change the pads including labor. Considering it took me an about an hour to change all the pads, I'm puzzled as to why they would charge so much. Regardless, I saved myself ~$500 and more importantly hours of being without my baby.
But as for the pads themselves, they're great IMO. A tad less bite on initial contact (which I prefer anyway), no squeaks, and a lot less dust.

Just ordered these as well. Brakes started squeaking over the weekend.
LPI Racing had the best deal around @ $376.90 shipped.
Thanks for posting

Mines squeaking alot... I do have the stock rotors and swapped the stock pads out at 9000 miles, the shop that installed my Porterfields did tell me that these are racing pads which consists of a harder compound compared to the stock pads which are softer hence the reason why they squeak so much.. I didnt believe it and I still dont but I dont think I'll be going back to the stock pads, they produce way too much brake dust. Not sure if theres a way to maybe shave down the pads so that it's even with the rotor, maybe that's why its squeaking.

I don't care about squeaking - was just saying mine started, which means that it's time to change them. I care about stopping. Fast.
These cars are nothing. You should have heard the Pagid Yellows on my 996TT. High-pitched fingernail chalkboard shrieking all the time. Good stuff. Sounds like racing.

Wondering if the guys with squeaking bedded their pads after installation. I'm running this pad with GiroDisc and have no noise issue at all.

I know the Porterfield are well reviewed and a lot of you guys swear by them. But I LOVE the feel and bite of the stock pads and I am hearing that the Porterfields have less bite? That sucks, because I'd love a dustless pad but want to retain the stock brake feel (which is the best among in many many cars I have owned).

So my stock brakes are squealing and squeeking alot now. I am wondering if you guys that swapped out these Porterfield pads onto your used rotors continued to have problems with squealing and squeeking?

Brakes will always make more noise when you put new pads onto old rotors. If possible, you should at least resurface the rotors when you put new pads on to avoid this.
