got a track day coming up and can't decide between the porterfield r4-s or the r4-1

i have a stoptech BBK with axxis ultimates, and im afraid if i get the r4-s's they will be almost extremely similiar to the ultimates at the track.

or how do they compare to the hawk hp Plus?

thanks

 

Check out the Performance Friction pads as well. Great price and good enough for 2:05's at thill so far.

 

I run R4-S. Haven't tried HPS's, though.

It's a great street pad and dusts much more than the OEM Brembo ones... not a race pad, but it bites very well and is not very sensitive to temperatures under HPDE conditions...

R4-1 is a race pad as far as I can tell... I went for something great on the street that would be sufficient on the track... as I am not there often enough with the Subaru to justify race pads.

The Hawk HP Plus is also a high-dust race pad in the same category as the R4-1... just keep that in mind...

 

I wouldn't run the R-4-1 on the street as well. The PF's you can get away with it, albiet with higher dust. I daily drive my PF's.

the HPS's will melt down on the track if you are anywhere close to being quick.

 

R4-1's are awesome but will eat your rotors alive. Should be considered track only.
