That said, braking 5 marker sorta early (acknowledge you’re carrying way more speed than most cars) but you might want to try practicing different threshold braking points... OR maybe you can actually carry more speed into T1. What’s your entry speed? Thanks for the update btw. I just snagged a set of 335i calipers and CSL rotors and plan to install mid-season after I burn through my current pads. However I’ll be upgrading fronts only for now.

Awesome, can't wait to hear how you like the upgrade.
I usually coast after 150, hit the brakes at marker 5, get down to 70mph before the turn but am on the throttle before the apex. Like I mentioned, pedal feels solid, no fade. I wasn't aware 01s would provide more braking force, only because compounds are still new to me. Looks like 01s are no longer around?

You should be able to go little faster than 70 especially with the mild aero. Come out to Lightning in May and we can compare notes! |

Sorry for the hijack. I currently have a Z4 coupe 3.0si and a set from front Brembo GT brakes 6 pot spare from another car. I would need a bracket and possibly new rotors. Searched everywhere for just the brackets. Can anyone point me to the right direction? and would be complication with this mod? Cheers

Update: Had a track event this weekend. Ended up with a mushy pedal near the last session from heavy braking (long straights to tight turns). This is the Pocono Tri-oval to North course Twilight event.
I'm pretty sure I boiled my Motul600 freshly bled fluid (PFC08s). All 4 rotors were glowing red from what others mentioned. Not only that, but the rear 135i calipers which were Gray? are now Gold! Dust boots are also cracked on those 135i calipers. Hopefully the piston/seize issue is only a 135i front caliper issue. Was hoping to not need to upgrade (again) rear calipers after all that work. Front 335i clalipers with brass sliders working like a champ so far. This is partly my fault since I'm braking so hard, I'm entering the corners at a snails pace. Need more confidence to enter corners at a faster pace. I'm trying to not spend $4-6k on full BBK.

Holy smokes, you've got a lot of heat into those brakes. I'm similar but not nearly as bad. 3 track days and I cooked my pads. That 1st track day I boiled my fluid. The heat has taken the clear coat off my beautiful painted calipers but they're still Le Mans blue. What are people using for brake pads? I'm using EBC red stuff again, but I feel like I could go a little more heavy next time out. |

It's partly my fault (I hope) in that I have a habit of pitting in as soon as the checkered flag goes out. I have not been doing meaningful cool down laps. I'm sure the fluid just boils in the pits. Shame on me.
Going to SRF fluid next, upgrading from 2.5" front ducts to 3", and going to try to add rear brake ducts. Will also install the rear 135i metal pad shims, hoping it provides some relief to heat transfer. If none of the above help, then BBK it will need to be. When does the money bleeding end!

There's a guy on the BFC site that has added water cooling to his setup for road courses.

Hello dre99gsx Im looking at the calipers for E90 335i and for some reason they looks different compare to yours, could you please specify from what year and exactly model your calipers is, maybe part # One of you use is actually E60 M5 or E63 M6 calipers?

Sure! 2007 335i. In your photo above, it's the blue one to the right.

That’s because whoever had those blue ones went out of their way to fill in the hole on the clip/cover so they could put the sticker on

Don’t see a difference between the 2 blue ones other than the M decal. Regardless any E90 335i/xi front caliper will work as they’re all the same.

The 2 blue ones are different, and maybe there's also a size difference.

Oops, seeing this on my laptop and see it now. The left one has drilled rotors which doesn’t look stock for an E90 335i so might be an E60 m5. But the right one as Dre pointed to is right, that’s how mine looked on my old E90.

I'm not talking about the rotors, but the calipers itself.
Both blue ones are different. My guess is that the left one (with the m logo) even might house a larger pad. I speculate that the left one is an e60 m5 caliper with dual piston, or maybe even a dual piston 7 series. The other one is 335i You can recognize those dual piston calipers at the 2 extra slots (they're not going all the way through though) either side of the center slot where the wear sensor lead goes through. AK72 saw that very correctly.

Part of the issue here is that originally, these thread had plastered with Photobucket photos (which you would be able to use to determine the correct caliper). Somehow, they are all missing.
Sorry for the confusion.
