hey guys, looking to purchase a set of carbotech xp12 brake pads to my knowledge, the front and rear brake pads of my 360 modena coupe are identical correct? looking on the carbotech site they list the f360 and f360 modena but the f360 has different part number for front and rear whereas the f360 modena has the same part number for front and rear i want to double check before i put the order in thank you in advance
The size is the same but there is a sensor in the front (if you keep it). The xp12 will get you hot at the track. Make sure your fluid is high temp and fresh! If you call them up, they'll advise you well. Sent from my iPhone using Tapatalk
Yes, same front and rear. I've used Xp8s and 10s. Both were excellent and very long wearing without eating the discs. They scream like a banshee during light braking conditions in road use though. What tyres will you be using? 12s might be just too much to modulate effectively with road tyres. 10s are tough enough to use with precision on MPSS.
I use xp10/xp8 but with a 380mm BBK up front. Never had the need to move from xp10 to xp12 due to heat failure.... The weak point was the fluid before the pads. If you are looking for bias adjustments through the use of pads, maybe go xp10/1521? Any pads can lock the wheels... So that's not really the point.
i have experience with xp10 front xp 8 rear in my lotus - and felt that they werent enough so wanted to try xp12 in the 360 i ended up with CL RC6 all around on the lotus though, still debating on xp10 all around or xp12 all around - will be on street tires so not sure yet.. as for brake fluid - planning on changing it with motul rbf600 - how many bottles would i need? thank you in advance
The RBF600 has worked for me. Boiled it on the stock rotor size. Maybe four bottles for a full change? I buy a case so I can bleed after a day or two at the track. This is a very different animal than a light lotus. What do you mean by "wasn't enough?" Are you looking for more bite or just more brake? I think of pads with respect to bias and heat management and try to only go as aggressive as needed so the pads don't fade out. The cheapest pads will lock the tires. The more aggressive pad is going to cook your fluid hotter, and the stock system is not great at getting rid of the heat. I'd also stay less aggressive in the rear. Just is more balanced and the rear runs way cooler. Anyway, just what had worked for me. Sent from my iPhone using Tapatalk
what i mean by wasn't enough was just need more brake after changing out the combo of xp10/xp8 to cl rc6 - i got improved lap times etc.etc. with the ferrari though i want to try the xp12 all around but after your insight i might go back with the xp10/xp8 or even xp12/xp10 the 360 will only see 1-2 track days a year while the lotus is doing some maintenance or other stuff to it the weather here isn't as hot as SF bay and the ridge motorsport park isnt that brake unfriendly so i am sure the rbf600 will be fine since I use that in my lotus as well any recommendation on alignment as well? thinking -3.0 camber front with 0 mm toe and -2.0 to -2.3 camber rear with 1.0mm total toe in
The guys at CT should be able to advise you well. You won't want the xp pads on the street unless it's just from/to the track. They howl like F-Dub said above. I'm somewhere near -2.4 in the front and -1.8 rear. .5 rear toe. Couldn't get much more unless I changed to longer studs. Ride height front to rear really changes the handling too, it seems.

i have streeted the xp pads on the lotus no issue but the 360 hardly sees any street mileage - will only be to and from track so thats good what is CT by the way?
thank you just want to double check before i order - because it seems like the website changed all the fronts to CT1166 so i will order 2 sets of ct592
Maybe they have one that accommodates the sensor but is the same shape. I didn't care since I was going to rip them off anyway.
I think it depends on tires, weight in the car, driving style, preference, etc. I think most people move to CS height. My point was just that the car is sensitive to the rear height, so it's something to play with. Sent from my iPhone using Tapatalk
Hmmm I have the challenge car supplemental workshop manual that says 313mm/328mm F/R respectively for hub to top of wheel well. I'm currently at 341mm/355mm, but think its high for my needs. Prob could drop 1/4" all the way around and not worry about scraping around town.
I can't help feeling that the reason that the RC6s worked better for you is that the Xp10/8 were just way too high a friction material for that car. Consequently the ability to modulate and feel was lost. I presume we're talking about Elise or Exige? Many people would find even RC6 to be too much for those cars, even on slicks. I suspect you may find the same may with the 360 on street tyres. Xp12s are likely to have too much friction for the level of grip from the street tyres and may make it very hard to find and modulate around the threshold of adhesion. I've tried 8s and then 10s on MPSS. My next move will be down not up from the 10s.
car in question is a 2007 lotus exige s - had xp10/8 since stock to its current state (aero, suspensions, etcetc) i wouldnt say that xp10/8 were too high a friction material - more so it felt lacking - i've used them for about 1 year (8 track days or so) after changing over to rc6 i found myself able to brake later and lap times have went down as well during my sessions for nasa tt series many of the guys running in nasa tt series run xp12 square or rc6 square either way - i ordered xp12/10 for the 360 - lets see how it goes!

interesting, some of the people seem to measure certain points of the car to the floor - never seen that its measuring from hub to top of wheel well i will definitely give that a try thanks!
Grrrrreat little cars! Looks beautiful there. As you say, see how you go. Certainly I loved the initial bite of the Xp pads I've used. I had to lower the pedal when the I got the 8s and I had to lower it again when I got the 10s. It takes very little pedal pressure to apply a lot of torque.
