brakes Porterfield R4S For Volvo Calipers?

[Beach_Bum]

Anyone know if Porterfield makes the R4S for the Volvo girling calipers?

 

I'm upgrading my front brakes and the Porterfield website only lists pads for 1997 and newer Volvos, but I've searched the forum and found old threads where guys were running R4S pads with the old Volvo calipers.

I generally contact LPI Racing http://www.livermoreperformance.com/brake_home.html for Porterfield brake pads and shoes.  They've hooked me up every time.

You can also call Porterfield directly. They can build custom pads with any compound you want.

Thanks guys.

 

Just got off the phone with LPI and Porterfield. They DO still make the R4S for Volvo calipers. For anyone interested, the part number to use for ordering is: GD549.

 

The reason I was having trouble is that Porterfield does not have the R4S listed under GD549 on their website (only R4, R41 and R4E), but if you call they can place the order for you.

Great job! Thanks for the info! I have been wanting to upgrade my brakes as well.

I have that compound for my 2002tii stock brakes. Will be giving them their first true test this weekend at the track...

Haha, interesting side note. 

 

Wonder if porterfield got permission to use that background image.  Done by my old roommate/classmate while we were getting into trouble.

porterfield has lots of pads not listed on their site, and they custom make pads. i had them make the same shape for volvo calilpers with Performance Friction 01 pad material.

 

R4S compound is great for street and auto-x.  ok for beginner level driver's schools.  beyond that it is time to step up to a real track pad.

For street use in stock calipers I recently installed Porterfield R-4S pads and I like them alot.  Superior to anything else I've used in the 33 yrs I've been driving my '02 (I've put on 300K miles).

On a Volvo caliper, I'd bet the R4S would be OK for the track.

For moderate/occasional/not pushing too hard days.

 

On the stock caliper, I agree with Marshall-

 

beginner level driver's schools.

is about it.  Or maybe your first track season

while you're still running the single barrel downdraft-

they can't really take the heat.

But they're a decent street pad.

how do the R4s compare to oem pads at the track?  Last summer I cooked the crap out of a pair of oem pads, but they felt great on track... there was just very little of them left...

On the Volvo calipers, I tracked my street car with Textars on it a lot.  They did fine- mostly when I instructed,

so it'd be 20 or 30 laps a day, but they never faded, and even felt fine on the trip home.

The stock ATE pads did fine in my only PDX last year on the tight,twisty track at Summit Point. It was the Prestone brake fluid that failed and boiled. I now use the ATE blue fluid.

[gliding_serpent2]

Brake fluid is key. I think that is the limiting factor for fade. Non track compounds wear faster however

[Chamonix72]

Remember that ATE Blue is no longer available in the US. So, ATE Typ 200 (gold) it is. Or Motul's brake fluid that the Subaru guys like.
