How do these compare against performance friction 2 piece floating discs? Do you stock the girodisc s/s pads?

Thanks,

Chris.

SumoPower

Hi Chris the quality is on par with performance friction in actual fact we would argue these are finished slightly better. We stock both manufacturers so if you would rather a quote on PS just let us know.
The Girodisc Street and Strip (SS) pads are in stock. These are very popular with the Evo guys to do it fast road and occasional track days.

Love my girodisc discs. The pads leave a lot to be desired though if using both on the subaru brembos. Girodisc discs and pf pads

Ok thanks for the quick reply, I looked at some pictures of both, and the pf rotors looked better finished.
I couldn't find the pads listed for impreza or the replacement discs on your site?
How much do you charge for pf discs? They're not listed online either?

Many thanks,

Chris.

Thanks for the advice! Heard mixed reviews about the pads, but mainly good about the discs! Does the weight difference in rotors make any noticeable performance gains? Again heard mixed reviews! Most people think they imagine it... lol

They Don't,The PF set up is far superior,coming from a past user of both.SJ.

I've Also heard pf is better....

SumoPower

Interesting feedback. Perhaps you could expand on your experience?
What pads were you using on both set ups? Were the pads new when you installed the new discs?
In what way did The Girodiscs not meet your expectations and for what reasons?

SumoPower

We are direct dealers for PFC but I think we need to update the website with these products. We'll look to get these added this week Chris.
If you need any quotes in the mean time, please feel free to drop us a line.

To answer your questions,all set up's were both brand new,i personally don't recommend buying and using other peoples part worn disc and pads as they wear in according to the previous drivers driving style,plus they are not that pricey to buy brand new.The "magic pads" from giro that i used were absolute rubbish compared to the PF Z Rated pads,the girodisc were ok,but using them both hard on fast road/track the girodisc setup faded badly after hard use,the complete set up from PF wins hands down.I have no need to rubbish the girodisc brand but coming from experience if i was buying i would not look any further then the PF disc and pads.SJ.

SumoPower

It normal to get mixed review on any product, we have had 99% good reviews on both products hence why we continue to distribute them.
Ross Sport who are the main importers for Girodisc take any issues very seriously so its worth feeding back to us any issues even if you didn't buy them through us we will be happy to help.
In essence they are both cast iron directionally veined discs mounted (using different methods) to an alloy bell (Girodisc is 7075T6, which is aircraft grade billet alloy) - performance should be very similar and in our experience issues tend to come from poor installation ie, failure to check run out, or discs that have been rebuilt not following the correct procedure. Most common issues come from poor quality or contaminated friction material.

SumoPower

OK cool. Thanks for that buddy.
In answer to your findings, the Magic pads are an entry level pad designed to be low dust and low noise, providing ample braking force with very moderate disc wear when cold. They are not really suited long term to much more than normal road driving in our opinion, if you ended up exceeding their their effective operating temperature this would be easily done in a late Impreza given the weight and poor heat dissipation of the stock Brembo caliper, this would explain your experience. (I dont have any data on this exact pad, but similar pads loose their friction coefficient rapidly above ~450°C)
The PFC set up you had likely gave you a better experience due to a better choice of friction material for your application. We have a lot of customers who are big fans of the .11 material for fast road.

Your probably right about the pads as they were not up to continued hard use even on fast road conditions,the PF heat treatment that is done on all there disc WORK and even there entry level Zrated pads perform even after very hard use.You are right about the .11 compound it's a very superb pad,it was brought in to succeed the original 01 compound i have a set for my AP calipers.I might have to give the giro disc another try but with a different pad and then let you know how i feel about them afterwards as my wife's Subaru is running brembo calipers.SJ.

I've also read on the MLR that these wear very quickly compared to PF ?

SumoPower

Wear is a very interesting topic, and getting an acceptable level of of braking force v's wear at the temperature that you intend to run is entirely down to the pad choice.
The MLR guys are very keen on modern race friction material, which is awesome stuff but doesn't come without its down side, the main one being dust and noise, secondary to this is massively increased wear rates at low temperatures (when braking hard) This will be the case during most road driving scenarios. If you want the benefit of race friction material I'd recommend warming the brakes slowly to get them up to temperature before really giving them stick, once they are up to temp the disc wear rate will be much less than jumping on them from cold.
I'd recommend researching pad transfer layer & temperature if you aren't familiar with this

SumoPower

Good stuff, give us a shout if we can help with either option SJ.
As above, get the friction material right for the application and both makes should work equally well.

Thanks,I will keep you in mind.SJ.
