Porterfield R4-S pads available for 2012 2.0T Ltd.

Hi, new member here.

I contacted Porterfield after buying my 2.0T in Dec 2011 asking for performance pads for the 2012 Limited. They fulfilled that request this week in the form of their R4-S and the pads are now available. I received mine today and will be installing them in a few minutes. I'll provide feedback on performance after I give them a try.

Any word on decent, drilled/vented/slotted rotors? Or are the factory ones sufficient?

Current Mods--Too many

The front rotors seem OK. They were vented. The rears are not. I think that tirerack has options for the 2011 2.0t SE. You just need to verify that it's for 18" wheels.

Prior to dropping any serious cash I'd recommend steel lines, better fluid and better pads first. I changed out my tires at 1200 miles for Continental DWS tires--the first element in braking is better rubber. I am now on a mission for steel lines and then will use ATE super blue fluid when they go on.

Please keep us informed and I am very interested in how much dust they give off.

Strange...I don't see an edit button to go back and edit my original post...

These pads are performance street, meaning that they'll take what you can throw at them during spirited driving. They'll also do for AutoX. While my preference is for Ferrodo DS2500's, which are on my Subaru, I doubt Ferrodo will ever make them for the Sonata. However, based on reviews and friction coefficients, the R4-S's are not far behind in terms of performance and *appear* to be the next best choice after the DS2500's. Keep in mind that this is a highly subjective subject , your mileage will vary.

What the pad upgrade will do is provide fade resistance after successive stops. We need steel lines and fluid to get a consistent and hard pedal feel. All three combined will provide for confident braking. I don't know about the rest of you, but the feel of the brakes on this car is horrible. Especially if you hit the pedal a few times in a row. The single piston calipers are horrible!

Comparison of R4-S's versus stock pads:
Front:
R4-S on top, chamfered edge, more pad on the rotor. The stock pads have a 90degree drop off.


Rear:
R4-S chamfered, stock 90degree drop off. Same size although the picture is misleading due to the chamfer of the Porterfields.


Caliper removal.
14mm wrench, upper and lower bolts come out.




Take each bolt off, pull inner piece of the caliper out and rest it on something. Do not let it hang by the brake line. Pull pads outward from caliper to get the little wings out of the retention grooves, the pull towards the back edge of the caliper. Do one at a time so that you don't get the two mixed up. The rear pad of the set is the one with the large retainging clip.


Install: Fronts
Take the backing plate off the new pad. This is the pad on the backside of the caliper and the one that the piston presses. This pad is the one that will have the large retaining bracket on it.


Take the backing plate off the stock pads and transfer to the new pad (same pad as above).


Depending on how worn your pads are you may have to take a c-clamp and press the piston back in. Use the old pad as a backer so that you don't mess up the face of the piston.
The rears: need only to transfer the backing plate on the rear caliper pad to the new pad.

I add high temp brake anti-squeal to the back of the pads that will have backing plates (both on the front rotors and one on the rear of the caliper on the rear rotors).

Total time to do the job once the wheel was off: 3 minutes per rotor.

I use R4S pads on my S2000 and am very happy as it is a good street compound.

I would not use drilled or slotted rotors on a street car... more noise and wear for just a little bling.

So far, I'm very pleased with the pads. I put about 15miles of around the town driving on 'em and they've improved the braking and pedal feel more than I thought I'd feel with just a pad change. In fact..my wife drove the car and told me she felt a difference. That, in and of itself, is HUGE ... I'm not sure she'd even notice if I changed the color of the car.....

looking forward to hearing your opinions on these pads over the next few months as far as noise and rotor wear go. Also, how are those first few cold stops in the morning?

The first drive surprised me being that there was no transfer of material onto the rotors, yet the pads worked really well. Temps were in the 50's with rain. We'll have a high 20's morning on Tuesday so I'll be asking my wife to report back on how they work. No squeaking thus far at any temperature if that is what you meant by noise.

I've been running more aggressive DS2500's on my car and both cold braking (low 20's winter commute) and rotor wear (60k miles on the rotors w/DS2500s) have been great. That includes autocross with the occasional high speed autoX's that we set up for a local Viper club. I expect the same from the R4-S's.
