It looks like the increased the track by changing the wheel carrier.
So fitment looks to be the same pre-LCI and LCI.

That means, either mill down the caliper like me and you did or go with mill down 135i hubs.

I'm not sure if there's any truth but they weigh a bit less & are two piece rotors so it's easier to DIY

No significant weight saving and those rotors cost a lot than regular once. You are better of spending the difference on better pads, ss brake lines and good brake fluid.

Baffles me why an engineering company hasn't made something bolt on fitment out of the box. Should I go for the BMW performance 6 pots or the M sport ones? Which are easier to fit front & rear?

The six pots from the 135 fit front and rear. But for the front the swept area is smaller so you will lose braking performance.

The M-Performance kit is plug and play on the front but you need to modify the caliper for the and open the holes on the wheel carrier.

I would not go with the performance rotors in the rear. I'd go with stock drilled or dimpled rotors so that the fitment won't be at critical.
The performance rotors are thicker so centering the caliper becomes critical.

Go back and read through the thread. Lots of information.

+1 on everything. Plus the 6 pistons from the 135 is $1500 just for the front > totally not worth it since they are 338mm rotors and the pistons are known to melt. Shitty setup! Don't buy it!

RB and ST make piston/seal/boot kits for the 135 front calipers and while they're a decent upgrade for a 328i they're a downgrade for the 335i. Much better improvement to change the caliper guide rod bushings to solid parts. Then again they're not winter friendly.

I agree with you Pete!
You have first hand experience on most of the possible upgrades on the e9x chassis.
True, you can build the 135i brakes to withstand abuse but the RB and St upgrada kit is about $200.
If you want to get better pads, another $200 probably and you will get close to $2k with stock rotors and ruber brake lines.
If you upgrade those too it will be more money than 355mm ST 6piston kit which will perform better out the box.
For these reasons I advice against it.
If you have the calipers on you car already, well, that is different scenario...

Yeah, the 135 upgrade is $1409 complete at Turner and I did sub pre-broken-in Carbotech pads which weren't cheap at all. It's not a cost effective solution, no question. If the calipers and rotors were available used it could be I suppose, depending on condition, and the upgrade to the pistons, etc. would still need to be done.

With the options available today I wouldn't do it again, I'd likely do the F30 front upgrade instead since there's no point in changing the rear brakes. Seriously considered the STs for the front, not real sure anymore why I bailed on it, hmmmm....

I have a 325d LCI E92, you say the 6 pots performance brakes fit front and rear? With no modifications?

I'm from the UK, do you know any companies that make the piston upgrades over here?

I've read this thread, but there is a lot of information of which I'm not sure is relevant to me as I don't have a 335 pre lci.

Yes, to my knowledge the 6 pot performance brake will fit front and rear, but no offense, why do you need it? Is 325d that I assume you don't track so the stock brakes are adequate.

Because 308 bhp and 620 nm of torque, plus the brake callipers are ugly and painting callipers just makes them stand out even more.

very good numbers, that 325d is properly quick than!

She defiantly isn't any slouch. I'm going for the 6 pot Performance option, will change the pistons and brake lines at the same time, unless someone in the UK can offer me a set of already modified M-Sport brakes.

Hi,

I want to share my experience with 335i Cool Carbon brake pads and ECS Tuning customer service.

DON'T BUY THESE!

The balancing weight will fall off and possibly jam up between the caliper and the wheel !

Very dangerous!

ECS Tuning WILL NOT WARRANTY the defective pads.

I guess somebody needs to slap them with a laws suit in order to change the attitude.

DO yourself a favor and just don't buy them.

Damn, sorry to hear that.

People usually have pretty good experience with ECS, its weird they dont cover defective pads.

Thank you for the update.

Talking with my customer service reps, a resolution has be come to with feuer. Sorry about the situation.

Also please note after talking with the guys at Cool Carbon they stand strongly behind their pads, if anyone has an issue with their pads please reach out to me and I'll work with you and the Cool Carbon crew to come to a resolution.

Good stuff. You guys should put together an F30 brake package, with pick your rotors, pads,, and caliper color options and optional m3 master.
I'd like gold calipers, slotted and drilled rotors preferably stoptech, and ceramic pads. Maybe cool carbon. It'd be nice to oneveryone stop shop it and know you have it all in a kit.

Yes, but if you consider the initial approach to the issue that was absolutely disappointing sending new pads to me is not a resolution.
The person copy-pasted me something from your website stating pads don't have warranty.
ALL local parts retail sell brake parts with warranty, some even offer lifetime warranty!
I have access to deep discounts under shop account and go to ECS solely out of convenience and not money saving.
If the above practices doesn't change customers would much rather drive around to get the parts instead of ordering online from ECS

Ro1024 answered your question.
It will be very difficult to match and even harder to beat those prices.

Hi planning to get the M performance brake kit but was wondering whether the M3 18 inch rim Style 260 would fit the 370mm rotors and caliper. hopefully someone can chime in, cheers thanks!
