The only way your lasting 30 minutes is your coasting cool down laps before you go in for 1 time attack style lap and thats not what i'm after. I want to hang lap after lap and get a good rythm going.

All those other more "challenging" tracks have nice high speed sweepers to cool your brakes off on. You'll see when you actually run here. Give me a time and date i'll bring all the "fresh" brake fluid you like.
If you need BBK to have faith in your brakes then I can't change that. Go ahead and order it. My brakes had complete fade once but I've learned to retrust them. Thats why I never change brands on my brake parts, hasn't failed me yet.

Look up iCar and Mosport DDT, or Shannonville if you want to see a track with a lot of braking. And yes I go 30mins no cool down in between. I could post a 30min long clip on youtube but that would be super boring. So heres a 10min clip
. I wasn't trying to cool down once in that, and I was already out for 5 laps before the start of that edit. I really start cooking at 3:00 onwards. Watch my late braking in turn 1, I brake within 100-50m of the start of the turn lap after lap at the top of 4th gear (shep ultimate ratio trans with 4.11FD gear). Total faith in my brakes.

This guy is pure comedy. We could state planet earth is round and Canada is part of the North American continent and he would argue with us about it.

Nice well i'll believe it when you run mission.
Compare the two videos and you'll quickly see what I mean. After the one long straight away your spend more time on your brakes at mission than you do your gas.
Compare the run off between the two tracks and you'll see the consequences of what happens if your brakes arn't 100% rock solid. By that i mean the BUSLENGTHS of green you have on either side of your track if you were to go off. Now bring those brakes and your big brass bawls and see they hang here.
See all the red lines I added? Maybe I added some extra concrete barriers there just to scare you off!
C'mon earn yourself a free BBK. Easier than it looks!

Thats iCARs circuit map. It has high friction concrete as well that generates a lot more grip (and wear) on tires and brakes. Trust me its harder on brakes, I've seen both. Mission is most similar to Mosport DDT in the east.


This is a STI (see terminal understeer) at iCAR. You think mission is bad? NO room to mess around on iCAR. Yet somehow ct9as and cz4as are OK on stock brembos lap after lap...

Can't see much from the video aside from it's dark and looks like he spends 80% of his time in 2nd. Pretty hard to cook brakes if spend more time part throttle turning than you do braking. I see two points at best where he might get close to the top of 3rd on that track. Thing looks like an autocross track. If you can't see why you'd be spending 2-3x as much time on the brakes at mission vs your icar track then theres no point.
Mission I'd be topping out 4th in at least 3 different areas.
Like I said bring it and show me how it's done.

I say this with all due respect mate, but maybe you could take some pointers from that sti driver. He seems to be having a ball and it sounded like he was more worried about the short shifter than he was about brake fading.

Having 0 idea what his braking setup is I find that to be funny. Your entitled to your opinion.

I do 4-5 20min sessions with no issues, though I admit I'm not on r-comps.
Tapping the pedal works great. I get a bit of knock back too and tapping the pedal helps the brakes feel far more responsive.

You guys really need to quit feeding the troll, though LOL

if you read the description on youtube of the video you posted you'll see he is stock apart from hawk HP+ pads

" A few laps around Mission with at a VCMC club track day. The car is stock other than a front sway bar and a new set of Hawk HP+ pads all round. The stock tires are a little tired after a full day, this was the last session. I try to keep infront of a GTR but there is just no way. Thanks to Michael for the great camera and editing."

you're entitled to disprove your own video

You do realize iCAR is a 3.4km track and mission is a 2.2km track right? If you called iCAR a go-kart track (they do have a separate smaller go-kart track) then whats there to say about mission.

The fact that there is no long straights to cool the brakes down is the issue. Its a lot of low speed work on the infield which is terrible for brake cooling. The fact that there is little run-off room and concrete walls every where is what I posted that vid for. Obviously didn't end well for that STI driver, yet still he didn't crash because of brakes. He crashed because he froze seeing the wall and that infamous subie understeer.

Regardless I'm now with Bryan. Go out and buy a BBK. Good luck on your racing endeavours. Post vids so everyone can bask in your glory.

It's a different platform and yes stock brakes are typically fine for stock cars. If I ran at stock boost I MIGHT get by on stock brakes as well.

Longer straights = longer braking points(more heat build up) unless you have big sweepers. If you think otherwise then please do show me a video when you do mission.
If you spend half the time on the track transitioning between turning and gassing in the same gear how much are you REALLY using your brakes? Exactly my point Icar looks hard on tires not exactly on brakes. I will agree there is one place where I havn't needed bigger brakes and thats at autox.

Not sure they even break 200km/h in a race car. Evo put up a great fight tho Where did this evo suffer? Aero/slicks/turning AND braking. IMO he would have stayed ahead with better brakes but I'm sure you disagree. Sad that this video kinda summed up the thread title.

As testament to not going out for a 30min cruise every session, I enter the track grounds with a full tank and have a 5gal jerry can (94oct pump gas). My last session of the day ends when the jerry can is empty and the low fuel light comes on again.

I bet you were the kid to get caught with his hand in the cookie jar and still be adamant that it wasn't you.

Im going with what kaj said, im done here.
Goodluck in solving your braking issues

If Mission is anything like Mosport DDT, even with 500 whp, you don't need more than stock brakes.
