Default Brake pads - sell or trade Porterfield S4 R4S

I have a brand new set of front 928S4 brake pads from porterfield. willing to sell or trade. $75

they are probably the best street pad you can buy, that has ability to be pushed on the track as well.

https://www.lpiracing.com/Porterfiel...-Pads-c762.htm

if you combine this pad with the bed in procedure i have given to 100s of rennlisters, you will have no noise as well. If i can bed EBC oranges on a street car,and have NO noise, you know i know what I'm talking about because those are normallly crazy noisy. PLUS, my race car runs PFC11s with NO noise, not even in slow , light braking conditions, always! (even easier to bed Pagid black RS14s) but both are pure race pads. great stopping power and feel cold or hot and almost no dust and very kind to rotors.

let me know .. if you have a used windshield , i could trade for that as well. if you use my bed in process, and they squeak... money back guarantee.

I can add that these are pretty good pads, to compromise a streetable (quiet and grippy) pad for some HPDE use.

Yes, they dust, but its carbon/kevlar, and WONT eat rotors, so the dust is never ever going to rusty/stick/stain any finish, and comes off easy.


Its a solid hybrid bad, I run them now, just looking myself, to try something different because I can get em super cheap..and they're always easy to swap out.

A good partner in the rear for this pad, is the Porterfield R4-1, which is a superb 0-500degree pad, with a higher friction coefficient...so if you dont have an uprated bias valve, this is good stuff. If you do have an uprated valve...can still be very useful, but just like uprating the valve two steps, be aware of what this means.

So, you sound like you are making a move due to the dust factor. there are harder pads that dont dust, but have noise.. i can help you bed them with a no-chance of noise . my process allows the pads to be bed to the rotors , very similar to how the factory beds pads for race teams......but a lot easier.
let me know if you want to hear more.

if anyone is interested in the pads. let me know... BEST offer. i have no use for them anymore.

I run R4S pads on our 2013 Odyssey due to the fact the OEM pads tend to leave deposits and then cause vibration. So far these pads have been great, dusty but I prefer that over chewed or pulsating rotors.

Ya...many people believe pulsation is a warped rotor..and you are right.

When a pad (cheap or otherwise) is used outside of its heat range, it may deposit pad material on the rotor, and that will be a sticky point for the brakes. Over TIME, this point on the rotor wears less than others, then on a lathe, looks "warped".

Some 200 grit..clean it up, GTG in most cases.

Mid 2000s Anything Chrysler/Dodge for sho.
