Throughout my thread you can see that I discuss my options, in a round about way, for parts and why I chose that particular item, then try give feedback on how I rate its performance once fitted . So onwards with the next round of choices
Brakes
While my 1" brake master cylinder upgrade and new Motul RBF600 fluid felt great on track last time it was in the wet so peak temps were well down on what I will experience in the summer during competition. I am happy with the braking force of the OEM set up but not happy with the way it deals with heat.
Fronts
I have on order a new KSport 330mm front brake kit, and fitting the 1"MC was a forward thought to accommodate these larger calipers. I am debating what pads to use with them. I am a fairly gentle braker with OEM brakes but I want a pad with extreme bite. I am hoping pads with very good bite means I dont need to push the pedal as hard which means there is less chance of locking up the rear brakes. I am going to try and not use a brake bias valve and only fit one if I experience problems (one less thing for me to fiddle with).
The pads I have narrowed it down to are the Pagid RS15 and Carbotech XP10 as they are both commonly used on track, are both available in KSport fitment, and are both around the same price.
The specs of the Pagid RS15 pad with friction level:
Cold - 0.50
At 100°C - 0.57
At 300°C - 0.54
Max at (@ 600°C) - 0.62
Constant working temperature: 400 – 800°C
Max temperature for short period only: 900°C
The specs of the Carbotech XP10 pad with friction level:
Peak Friction Coefficient: ~0.60
Not a lot of specs available for this pad but they get good reviews and there is this technical blurb from Carbotech:
Carbotech wrote:The XP10™ has a very strong initial bite friction material with a coefficient of friction and rotor friendliness unmatched in the industry. Fade resistance is in excess of 1650°F (898°C). Due to the high level of friction and bite, this material is recommended for cars weighing around 2,900lbs or less. XP10™ still maintains the highly praised release, excellent modulation and rotor friendliness that have made all Carbotech™ compounds so successful. Carbotech™ XP10™ is not recommended as a daily-driven street pad due to possible elevated levels of dust and noise.
Rears
I am hoping to use the Performance Autoworks rear brake setup, 302mm rear discs with the standard Lude caliper. If that isn't possible there is a rear kit from the US for £250 or something that does something similar, 315mm ish discs. The way I am going to attempt to balance the braking between the front and rear is through my choice of rear pads. In theory pads that do not have a high a braking efficiency will allow the disc to continue rotating under load. If I lock up the rears I can swap out the pads for something with a lower friction coefficient.
My initial rear pad choices are the Hawk HP+ or the Ferodo DS2500 since they are both cheap and easy to get hold of.
