Hello, I wanted to let you guys know there is good potonitial in our stock sized brakes this 2 piece Brake rotors from ECS are no joke am going SC ESS 625 with my E90 M3 so dicided to try this out. In the Past i have used BBK like Stop Tech and Bear on an SUV i used to have and in both cases i felt the cars lost a little bit of that easy Daily driving efortless brake feel. Due to tha fact i do not own garage queens and i do have another car i still drive the ///M on daily basis and to be honest unless you are a Time Attack, Autocross trackday every week guy this brakes along with Hawk 5.0 ECS Stainles Steal brake lines and Motul 600 Competition Brake Fluid or any other combination that you might prefer .

I have had this set up for over 3 Month now and more than stified huge improvment in my book with the plus tha they look AMAZING! i also have their 12.5 spacers in all corners.

Richard

these are direct OEM replacement parts correct?

i notice ECS also includes their rotors in the F10 M5 BBK Upgrade kit for E92 M3..why not just the OEM M5 rotors? a fitment issue?

My car has 70k now with the OEM rotors, might as well upgrade for to these for damn near the same price as OEMs

Yes, the rotors R_lara reviewed are the direct replacement rotors.

The F10 M5 Caliper big brake kits uses 382x36mm rotors, not the 400x36 rotors found on the F10 M5. This was done to allow the use of the factory 19 inch wheels on the E9X M3 with the kit.

This is hands down the best Bang for the Buck on brakes for the E9x Platform just chose the pads that fit your needs and your done.

Idea for ECS make a belly pan kit with air ducts to the front rotors...

thanks for the clarification!

theres quite a bit of debate on an st60 setup vs this f10/m5 bbk swap as theyre closely priced. what are your thoughts?

We need more reviews on these rotors.

I was hoping that they didn't drill the rotors as I prefer slotted only. Hopefully ECS has something in the pipeline.

I have the rears and posted in another thread. Cliffs notes : I think they are fine if you want a marginal improvement but don't want to blow the kind of money it takes to make a significant upgrade to rear brakes. Te fronts are probably more worth it if you're wanting to retain the stock calipers or just don't want to blow the money, that's where you need better heat dissipation and their fronts actually lose a good amount of weight. The rears however were not significantly lighter on my scales, though the vane count is higher. Hard to say it's worth 20% more money over the stock ones in the rear but sometimes people just want an upgrade no matter how small and these get the job done and fitment and function are just fine so far.

For someone who tracks at least 4-5 times a year, I wonder if the ECS rotors will do. Its ridiculous how much it costs to replace rotors on our cars when brakes on cars like the C6 Z06 cost substantially less to replace.

Having priced up a set of OEM rotors, the best deal so far is $1,200 + shipping which is bananas to me.

Mine have seen 2 track day events since the install, like I said I'm by no means a race driver but I can hold my own. Even got over exited under braking a very well track tuned evo and I got him every time... What would really compliment this would be air ducts directly to the front brakes to keep them cooler.

Today is hopefully the day, hahah.

I'm skipping the rear install due to some ordering issues with ECS, so I won't be able to make a full on review of the performance until I get the rear rotors and pads in.

The reason the slot is curved is for that same reason you don't really loose surface area.

Slotted and drilled is our only current format for these rotors.

Anything in the pipeline for just slots?

Personally, I could care less about the extra weight.
