Brake Pads replacement - What to try next?

I'm a fan of the Carbotech pads, but haven't tried the competition enough to know how they actually compare for my application. I have however, read a huge number of pad reviews and based on the price and my experience have continued to purchase multiple sets.

They are disc kind hot or cold. My fronts crack before they wear out and survive probably 4 sets of pads (off the top of my head). The dust is reasonable to clean off the wheels providing you don't leave it a while after getting wet/hot.
My only gripe is the rear pads can very occasionally groan below about 10mph. Normally fitting the anti squeal plates that come on std pads resolves the issue, but Carbotech do not normally supply these. I’ve just received a couple of sets and the rears were produced using alternative pads as cores for the back plates (Ian was out of stock at the time), so that is an alternative option to get the hardware. I’ve worked with Ian to optimise the rear FD pad size and depth to try to improve the longevity. They are far too small to survive long on track so Ian machines the friction material right up to the edge of the backing plate. This also negates the annoying lip on the disc as the pad uses all the friction surface.

Ian at Carbotech UK has been great to deal with and very amenable to making adjustments based on my feedback. He doesn’t stock FD pads on the shelf, but if you avoid the early season rush the turnaround is normally 1-2 weeks. Most of my trackday buddies run XP10’s. I’ve just ordered one set in the RP2 endurance compound to try.

I’ve got a set of Stoptech pads which I fitted for a 3000 mile thrash around the Alps. In comparison to the XP10’s they were less dusty, but had quite a notable drop in friction. Had to push the pedal quite a bit harder (929MC). Obviously wouldn’t dare use them on track. I started with the XP8’s and shifted to XP10 to improve longevity. Both work fine from cold.
 
Curious question.

Is it advisable to run street pads on the street and swap over to track pads for track days AND not change the rotors? Any issues doing this and needing to bed in the new pads every time you swap the other ones out?

On my daily mx5 I had I would swap between street pads and the ds2500s, ie only use them on trackdays. Difference being about £150 ! Never drove the rx7 enough to bother with that.

The ds2500 defo make my silver wheels look bronze after a full track day. Can't remember how long it took on street driving but it was noticable
 
Some pads are not compatible with each other. If you've bedded in with one pad, then ideally you need to remove the pad layer on the disc first before bedding in with the new pads. There is less risk if you shift to a more aggressive pad, but can be an issue the other way round. I personally have not had an issue on the few occasions I've done it. I normally run the pads cold for a while before bedding them in. Stoptech have got quite a few good articles on their site that are worth reading.
 
Just purchased front and rear Ferodo DS2500s. Quite expensive for these pads but less expensive than my Project Mu's.
 
They certainly cost enough but were recommended by so many including Stu at Rotor Torque who swears by them, so I hope they live up to the bill!
 
I thought you were looking for a step up in performance from the HC+ for track work? If you go careful on them, then they're half the price of a track pad, so a good cost save at least.

I was but the guys in this thread plus Stu at Rotor Torque convinced me to stay within the same realm of the HC+.

DS2500s were cheaper and it was recommended to actually run a slightly weaker pad on the rear so as not to upset brake balance so I bought Stoptech rears.
 
I personally don't find stoptech a weaker pad. I ran ds2500 for years and only swapped to stoptech because they were equally as good for less money.

Now the ds3000 were better but they were disc killers.

Also the stoptech bbk in the big rx7club bbk group test came out top from all the big brands. It especially done well because it retains a pretty neutral brake balance.
 
I’m using Carbone Lorraine rc6 and fook me they are sharp. Supposed to chew through discs though
