I’m looking forward to finishing off my E46 M3 great video bro

[@CapeRoadsPOV]

Really good BBK, drove a mates Focus ST here in South Africa with them and they had plenty stopping power. Great vid guys!

[@thedownshiftchannel]

Jason Clifton thank you dude! So far so good with them!

You got really nice cars 😍

[@thedownshiftchannel]

King Vega02 thankyou! Much appreciated

[@s4ms0n1t3]

how many shims did you use to make sure the discs don't foul the caliper when it expands?

[@DriversSide]

The red calipers look awesome! I want to get Brembos on my M3

[@thedownshiftchannel]

Driver's Side thanks! Check MS motorsports out raceparts.biz. The parts to do the brembo swap can add up to as much as this big kit from them!

i got a BBK of k sport 8 piston and 356mm disc rotos, but i need to replace brake pads and i am having a hard time finding where to buy them, can you help me?

[@komentatorius69]

damn. looks like christmas morning

[@thedownshiftchannel]

komentatorius69 it felt like it! Car parts day is always a good one!

[@sensoyguven]

how is the improvement on the car? did it actually make a difference ? thanks

[@E46Gaz]

Great video lads, good to see a great e46 example kicking around the north east too. Did you have to use spacers to compensate for the size of the new brake callipers and do you know if this kit would fit using the original oem 19" alloys?

[@thedownshiftchannel]

Gaz Ward thanks Gaz! The kit fits fine with oem 19s you won't have any issues! Stick around for a big update on this car soon!

[@tingsheannian]

quality parts^^

[@thedownshiftchannel]

Tingsheannian Ting thanks dude

[@jaso2003]

How often did you have to or do you have to change the friction ring? I feel reluctant to spend the 700-800 € every year or have you found friction rings that have the same dimensions as the Ksport rings (Tüv capable) that you can simply change them

[@thedownshiftchannel]

Hi. I only went through one set as they last pretty well. There are other options from reyland and AP etc if I remember correctly

[@cristianmoro6018]

What is the weight of the kit? Thanks

[@szk5334]

🍻

[@tt-hd6oz]

Do you think is possible to put the sport caliper (blue) for the m3 2013 in a m3 e46 !??

[@thedownshiftchannel]

t t I was considering trying but I haven't seen anyone else with them yet

[@christiancern4275]

Yes you can but you need to machine the caliper ears. My buddy took f80 m3 brakes put them on his e90. It require more machine for an e46

[@RicardoRivera-xt5ni]

Cute doggo

[@thedownshiftchannel]

Ricardo Rivera that's the only reason we don't get mad when she keeps getting in the way

[@djlakota8907]

Any noise from the pads, I'm running on K Sports 8 pot with K Sport pads, thing makes noise only when at low speed slowing down, especially summer. Cheers

[@thedownshiftchannel]

Only a very slight noise when cold and very light braking otherwise not at all. It’s down to bedding them in right also though

[@shahalam96]

hi @thedownshiftchannel, been 2 years now since you did the install. can I ask whats your opinion on the performance etc? thanks boss

[@thedownshiftchannel]

Hi Shah. To be honest after 20k miles I’ve had zero issues and they still work as well as the day they were fitted. I was planning to take them apart to clean and inspect and maybe make a video soon. I know people who run them regular at the ring in some very quick cars but other just go with the stigma that they aren’t AP or Alcon therefore they aren’t good.

[@shahalam96]

@@thedownshiftchannel Thanks, that sounds promising, I got 4 pot old brembo's which have 2 big pistons and two small pistons. I don't know if the K-Sport 8 pot callipers would be better than my current setup. Both Callipers are forged and the K sport uses new tech. Any thoughts?

[@nicolasfont2774]

amazing job man. I own a black carbon one SMG with 50K miles, cinnamon interior and 19 inches wheels but I really need your wallet to upgrade it,lol. wanna buy a status gruppe exhaust and a CSL carbon fiber trunk but I gotta wait a little bit, one more time you are doing an amazing job

[@thedownshiftchannel]

Nicolas Font thanks dude appreciate the comment! Yours sounds a nice spec it must look awesome and those parts are spot on! Keep up the good work

[@bradleytye6383]

as ive always said, you guys are 👌👌

[@thedownshiftchannel]

supercar showdown as always we appreciate the comment! Thanks!

[@rocketsteve9294]

*Taps brake pedal* *wheels immediately lock up* Jk, that big brake kit is awesome!

[@thedownshiftchannel]

Rocket Steve929 thanks! The pedal is certainly sharp but the bias is still good if not better!

[@nomessininc.]

they look sooooo nice, you planning on boosting it in the future adam?

[@thedownshiftchannel]

CATALYTIC UK it's crossed my mind but I am a big fan of NA sound and power so I may do some NA work as my project is going to be boosted

[@clfsti]

How are the ksport holding up paint and braking wear extra thanks

[@thedownshiftchannel]

They seem to have held up very well. I’m planning on taking them off for a good clean and inspection soon prior to a track day so il try to include it in a video

[@DriftingSquirrel]

Is it absolutely necessary to grind the pads? My D2's had issues with the pads, and I jus let them eat the exterior lip of the disk

[@thedownshiftchannel]

Yes it’s how you set the correct pad positioning I ran mine flush with the top so the disc didn’t lip as the pad has a square edge

[@DriftingSquirrel]

@@thedownshiftchannel so, let me see if I got this right. Your disc is getting a lip with wear or not? Do you have some picture of how the pad came to be and how it fitted?

[@thedownshiftchannel]

@@DriftingSquirrel no lip on the outside but the pad does not overhang at all it’s perfectly level with the disc after setting the pad correctly. Sorry I don’t have any photos

[@DriftingSquirrel]

@@thedownshiftchannel thank you mate. Do you see any drawbacks from it overlapping the disc on the outer edge?

[@thedownshiftchannel]

@@DriftingSquirrel just that it’s likely to crack and break away and you will not be getting as much pad contact as possible I guess

[@mattlott8766]

nice video sub.

[@thedownshiftchannel]

matthew lott thankyou! Much appreciated!

[@thomasgersbacher7055]

Is it me or should that brake disc be installed on the drivers side

[@BiglumpADV]

risking sounding like a right twit, i noticed the rotation of the drill holes/slots for the discs was opposite way round front to rear, does that matter?

[@thedownshiftchannel]

Tack2252 well spotted I also noticed thus whilst fitting them. The rear discs were refitted at they came off and the new ones as per instructions! Good observation!

[@BiglumpADV]

Hi, propably you've wrong direction of rotor

[@thedownshiftchannel]

Hello thanks but they are correct this is the direction

[@mariuszwielunski4323]

@@thedownshiftchannel look at old rotors and direction little wholes

[@thedownshiftchannel]

Yes these are grooved opposite but internal fins are correct direction. Better braking this way

[@GTRuppsala]

Are you still happy? Do you trackdrive?

[@thedownshiftchannel]

I am yes the only long term observation I would say is don’t be lazy and not clean them for 2 years with dusty pads. But with regular TD you would change more anyway. I’d like to do more TD but haven’t had the time

[@GTRuppsala]

thedownshiftchannel ahh ok nice..., I have modded an m135 for three years now and just ordered an TTE550 turbo and think I must upgrade my brakes..., but Alcon and AP Racing is soo expensive... I do track almost only now with that car so D2 in my case must stand fot heat... I want 380mm discs but they say I can only have 356 mm since I want 18” wheels... I havent decide yet but I’m lioking for references before buying since I gonna use them hard so they must work...😊🏁 Thanks for your film and comments...🙏

[@GTRuppsala]

I want them with dustcover but they doesnt recommended them if you track, which do you have?

[@thedownshiftchannel]

Mine do not have the dust covers. I’d advice speaking to Martin at MS motorsports he’s very knowledgeable on the subject. Pads alone can make a huge difference in braking

[@tingsheannian]

nice red colour body e46 m car

[@TheMoodyedge]

Man the e46 m3 comes with some shit brakes as standard. Heard a few people say they are crap. What's the verdict on the 8 pots??? Do a follow up review, be interested to hear what you think of them. your dog is the spit of mine :)

[@MRSUMAZ]

😜🤘🖒🖒🖒👍👍👍

[@thedownshiftchannel]

MR SUMAZ thanks dude!

[@DonateE36]

how much it cost ?

[@thedownshiftchannel]

Oh, is that what it was. I thought it was some dickhead swearing to a bullshit backing track that a 5 year old composed.

[@WillMulder]

E46's have dogshite brakes standard don't they? I don't know why either they should be good. How do these feel now you've been driving for a bit?

[@thedownshiftchannel]

Will Mulder sorry for the late reply didn't get a notification! The brakes aren't all that bad on the m3 they just get hot with excessive use and are pretty expensive to replace so it was now or never! These are very sharp it took some getting used to! The pads are a little dusty and noisy but very good so far! If yours are bad on the 330 try a fluid change for some good stuff and some decent pads with braided hoses it can make a huge difference

[@WillMulder]

No worries dude :) yeah that's fair enough, good reason to upgrade! Yeah I did a fluid change just with the stuff in the pressure bleeder at work, maybe I need to do it manually with some aftermarket fluid. I do give the old girl some serious shit so yeah I think you're right braided hoses might be just the ticket

[@combedpubes]

haha please tell me your dog is not really called Arthur Job mate, cracking vid otherwise lol

[@thedownshiftchannel]

Arnold Layne hahaha no the dog is called Mia. It was a half a job joke

Arnold Layne haha just checking so you don't report us for animal cruelty

[@combedpubes]

Nah yer all good lads haha have a good weekend

[@redovni1978]

This is k sport, you need to grind disc pads because they don't fit perfectly?! You should buy bmw performance 6 pot yellow brembo kit with 345 Zimmerman drilled floating discs with aloy hub and ebc redstuff pads, brake lines and adapters all brand new, plug and play, for 1500 euros. Great car by the way. Best M3 and the colour is awesome. Bavarian perfection from Munchen.

[@thedownshiftchannel]

Thankyou. Yes the reason you grind the pad backing plate is to set the contact patch on the disc perfect this is very common with other brakes too. They work very well. I am looking forward to return the M3 to das mutterland im sommer

[@thedownshiftchannel]

Or would that be “der” I’m out of touch now on German!

[@Situation7748]

hahahahaah 6:15 rust polishing no comment !! ....

Peter Lustig they have been extensively tested by a number of people both on street and track and proven they are capable

That's one rusty M3

[@thedownshiftchannel]

vailento it was! It isn’t anymore. We made an update video with the bodywork

[@vailento]

thedownshiftchannel Good to hear, wasn't looking very great! Will take a look later. Cheers!

[@thedownshiftchannel]

vailento yes unfortunately with all the salt they put on the roads cars love to rust in the U.K. it’s now much better than oem and should last!

[@TheMoodyedge]

Putting Chinese brakes on a German motor doesnt seem right somehow.

[@thedownshiftchannel]

They are tried and tested and work really well. They are engineered in the US and produced in Taiwan not China and are used in some race series such as EDC and time attack. Not really one to care about where a product is made if it works. Granted AP would be better but 3 times the price and not totally necessary in my case

[@TheMoodyedge]

thedownshiftchannel china Taiwan, same same lol

[@thedownshiftchannel]

Far from it. They do the job they are supposed to. Anything else is snobbery unless you require more which 90% of people don’t

[@thedownshiftchannel]

If you look on yheir about us section you will see they comply with TUV, ISO, EU and FIA standards which is pretty much as stringent as it gets. Have you looked at the R34 V-spec brembo setup? Might be a bolt on solution and they work well with good pads

[@TheMoodyedge]

thedownshiftchannel I have the r33 gtr so the brakes are the same and are shit.

[@Tropicsca]

Adding Ksport doubled the value of your bmw.

[@thedownshiftchannel]

Considering the kit is less than a tenth of the value of the car your maths is poor. Very bad math

[@Tropicsca]

@@thedownshiftchannel give it a couple of years.

They bottomed out 5 years ago then started to go back up. You clearly don’t know the market.
