    PFC.08 brake pads

    Thought I'd add a little mini review of these pads as I've been blown away by there performance. The PFC.08 pad are marketed as an endurance pad and are the pad used in the TMG Cup cars. I've had them on my car now for about 1000 Road miles and 600 track miles. They were fitted at the same time as a new set of Stoptech Centric blank rear discs and National Auto grooved front discs. I run Ate type 200 brake fluid. Cold bite - I was concerned that these pads would be a liability from cold but that has proved unfounded and in fact I have found them to give more cold bite than the Project Mu Hc800+ front and rear pads I ran previously. Noise - the pads do occasionally squeal a little but nowhere near as bad as I had expected from the reviews I'd read on line. I would say the squeal is a little less than I got from the OEM pads and they do not squeal all the time. Wear - I haven't taken them out to measure them since fitting but from a visual inspection the pads seem to be wearing very well (as would be expected from an endurance pad I guess). I'd been warned that they eat discs but so far the disc wear seems reasonable - there is no liping on the discs so far. The front discs do have some small heat expansion crazing but again, nothing overly unexpected for hard track use (picture below). Stopping power - this is one of the areas these have really blown me away in. The stopping power is simply amazing. On my first trackday with them fitted I found I was braking far too early using the points I'd had to use with the previous HC800+ pads. The pads can easily exceed the tyre grip provided by the AD08RS's I currently run (again, thinking of their use on the 86 Cup cars running slicks, this makes sense). Fade - I haven't experienced any fade with these pads on the four trackdays I've done so far, two of which were in 30+ degree temperatures at Bedord which has some quite high speed stops (two in quite quick succession after each other). I've been running maximum 30 minute sessions so whether fade would become more evident on longer sessions I couldn't say (for me, 30 minutes and I'm done!) Overall, I've been so blown away by how well these perform that my plans for a BBK have now gone right to the bottom of the list. Recommended as an option for anyone who tracks and doesn't want the extra initial expense of a BBK or the potential hassle with altering brake bias by just going with a kit that fits rather than one matched to the car.

    Big brake kit time?

    Tyres definitely are the most important but having said that , if you add another variable to it, temperature, the tyres mentioned above will not be as good at reducing braking distance below 4 degrees C as a good set of winter tyres and also most high temp brake compounds work well when warmed up not cold. So brakes + tyres + temperature determines the best stopping distance. Sent from my SM-G970F using Tapatalk

    This is worth a read for more info on bias:- https://www.brakes-shop.com/brakepedia/general/brake-bias-and-performance In 'normal' use (probably 95%+ of the braking people regularly do) you won't really notice any difference in braking. In 'extreme' use (a proper emergency stop, hard use on track, etc) if the bias has been shifted forwards you will see an increase in stopping distance. The big thing many people seem to forget is the effect of tyres as they're what really do the braking. If you're running a tyre with poor grip (something like a Toyo T1R for instance) your braking is going to be more limited by the tyres than anything else in your brake system. A grippy tyre (like a Yoko A052 say) will be able to handle much more braking force being applied to it before locking up. A good rule of thumb I saw is that if you can trigger the ABS you're tyre limited not brake limited for stopping.

    PFC.08 brake pads

    That's pretty impressive performance from this setup. 30mins sessions on track is quite intense on the standard disc and caliper setup. I've seen your lap times and YouTube evidence to prove your not cruising round the circuit as well. Great to hear it works well from cold also.

    Window Stickers

    Has anyone done or can do the club stickers but to go on the inside of the windows rather than the outside? Like the Subaru owners club one in the image? Sent from my LYA-L29 using Tapatalk

    Thanks both and that’s an interesting read Deacon on how it upsets the brake bias, especially as I plan on having a go in the TSS 👍
