How is best way to upload pics on here?
I load the pics on SELOC and link from here to there ;-)
Ahh good idea, will do that next time
I took my FK8 to Spa this weekend, it was an absolutely epic track day and the car performed amazingly.
The only problem was with overheating - the coolant temperature warning light would come on after 10 mins of hard track use. The car would then have reduced power until it cooled down again. It was 22 degrees Celsius at about 70% humidity - warm, but nothing crazy.
I've seen plenty of posts on Civicx, but their climate is far hotter than here. I can't find much about it on this forum - has anyone else had overheating issues in similar conditions? If so, how did you cure it?
A few minutes, maybe 5 or so.
As an aside, does anyone else have issues with the caliper paint after track work? My Brembo lettering is now yellow.
Blimey, those calipers are ruined!
I did look into titanium brake pad shims a while ago, but I'm not convinced they would cure the issue. They would delay the transfer of heat for sure, but they're just another heat sink, so after a few laps they'll be up to the same temperature as the rest of the components. They'd also continue to put heat into your calipers after you stop.
I would have to disagree Matt, with good fluid and decent pads I have not had any braking issues the fully floating discs I use are also very good and have improved cooling over stock.
I have never once had smoking or faded brakes, even at Cadwell or Rockingham.

I did one full day at Donington with full oem setup and the stock brakes worked fine for me, even 2 up. I did however leave all TC systems on and I went through a full set of rear pads, the fronts used about 60%.As you know I haven't tracked mine so, what I was referring to was factory set set up. It was promoted as a track focussed car but with the cooling issues and never having confidence in the brakes although better with decent pads it is disappointing. Be interesting to know how hot the brakes need to be to change the colour, you would expect Bremos to have very high temp paint.
I do think with a track tyre you will find the limitations, once Honda sort out what they are doing I will hopefully get an opportunity to get a car on track.
Agreed, I've never tried standard pads but with Pagid RS29 pads (standard everything else, including fluid) I've never had any issues on track. In fact I'd say they feel no less confidence inspiring than my dad's 996 GT3 on track, which has massive brakes, Castrol SRF fluid and proper cooling on all four corners.I would have to disagree Matt, with good fluid and decent pads I have not had any braking issues the fully floating discs I use are also very good and have improved cooling over stock.
You can overheat brakes on track by 'road braking' - e.g. longer braking periods at half pressure rather than shorter 100% ABS braking periods. Doesn't leave them much time to cool between stops, might be what you experienced?Said it from day 1, the brakes are great for road although far from perfect in my opinion, had mine smoking after an enthusiastic drive up Hartside, but simply not good enough for track. The car is too heavy, you need better calipers, discs, fluid and pads for track. I suspect but have no idea that some additional cooling is required too.
Good point re track vs road braking, I nearly always use my brakes on track with the wheels on the verge of locking/threshold of ABS activation, can't do left foot braking with power on the stock CTR but happy the oem setup is so balanced chassis wise.Agreed, I've never tried standard pads but with Pagid RS29 pads (standard everything else, including fluid) I've never had any issues on track.

There's also the possibility that it was the first time your brakes got properly hot, in which case pads being bedded might smoke a little and feel spongy. Once cooled, they'd be fine on future sessions though.
