now,

i'm not sure if you guys remember me posting about some dude in singapore running brembo 6pot fronts and 4 pot rear. well, i've managed to find the supplier to that kit. they are a brembo distributor that also specialised in reconditioned brembo parts such as porsche and audi BBK. the 18z model that is OEM for most of the VAG group cars.

long story short, i've managed to link up with them while i was in singapore and got my hands on a 6p front and 4p rears with slotted discs and mounts to run radial mount and dual caliper rears. i didn't manage to bring home the rears to australia due to luggage weight but the fronts are going up tomorrow along with SS brake lines. the rears will be coming shortly, the moment i've found a decent way to get them to me.

My main priority is better braking for the track. where i live, it's a very technical track with long straights and heavy breaking. if anyone is interested in a set, feel free to hit me up too.

Definitely in for more pics and impressions after it's done. How much did you spend?

so i paid about 4500SGD (approx. 3300USD) for both the front and rears.

this is the set up i was going for. this guy is running 18in rims. but i'm not sure off his offset which may have made the difference in the caliper clearance issue i'm having at the moment. i'm running +45 on a 19x8.5 and i suspect the guy is running an 18x8 with a lower offset, something like a +30 or something..







pretty straightforward for the fronts. the rears will be a little more complicated due to the rear dual caliper. i decided to cut the brake shield by a bit although i was advised to remove them completely.








this final picture is running a 25mm spacer that i borrowed from the workshop. unfortunately working on your car on the weekends mean everywhere is closed at that time, i will fix it during the week and run a 10mm spacer for the time being before considering the offset for the rims i have when i have the time.


disclaimer: my intentions for this is purely for the track. however i will unlikely be taking it to the track soon as there's no open days in the next few months and until i've managed to get the rears to me and fitted them on. it's definitely an improvement on the streets but it's definitely capable of more which i won't be doing on the streets. currently they're running brembo street pads while they will be swapped to ebc yellow for trackdays.

Very cool. Looks really good with those rims.

Please keep us posted as you test them out and thanks for sharing the pics.

Thats a huge in increase in fluid capacity and piston area. Have you installed a larger master cylinder to compensate?
no. not yet. not at this current moment. i'll work all 4 corners and see how the pressure is then decide on what's next..

What are the dimensions of brake disc - diameter and thickness?
they're 355 fronts and 330 rear. x 32mm

Were the spacers needed to fit the BBK or are they for looks?

I have 5mm spacers in the rear now and the tires sit pretty flush. Not sure I could go that wide without rubbing.

for mine, the spacers were required to clear the bbk because of the offset of my rims. if you're running about +33 or +30, i'll say there'll be no issues. however, for the rear, i've not fitted it yet. but it's a 4pot and the cross section should be smaller than the 6pot. sadly i couldn't find any info on the offset on the initial mazda that i had taken a photo of.

also it'll really depend on the design of your rims. konigs provide no indication of whether it'll clear a bbk but when i was looking at volks, they did put markings on their webpage to indicated which offset clears BBK

I don't think I could pull those off. They are very cool though.

I was looking at the Corksport BBK and they have the following template for their kit, so you can test if it will fit or not.

https://corksport.com/support/instructions/AXM-3-411-10 Brake Template.pdf

They say the BBK fits OEM 17" and 18" rims without spacers too and it comes in 3 colors. Kind of tempting.

i think for mine, it's down to the design of the rims where it concaves to the hub area. the design plays a part in the offset too. some will work with greater offset but for some you'll have to go lesser. when i got this, the guy was running 18" rims and it didn't occur to me at that point about the offset since i was running 19s. then it occurred to me that it might be the issue when i couldn't clear the calipers by a couple mm. it could potentially be down to the design as well because the SSR's he got on didn't look like an aggressive offset.

to be fair, if it fits the OEM, it should fit most rims. but then again, given the design of some, you can't be too sure. ideally i don't want to run spacers. i'll get a proper set of spacers for the time being and then consider if the +35 offset in the same rims will clear the calipers..

okay just an update. pictures will be at the end.

went back on tuesday to install the camber bolts and have a look over everything while driving it over the weekend. realised there was a little leak of fluid over the weekend. my mate didn't tighten up the bleed nipple tightly enough so that accounted for a slightly squishy pedal feel. i initially thought it might have been the master cylinder but after doing a once over making sure everything was tight and solid, the pedal feel changed over the next few days. so final thoughts, for now with front installed, master cylinder still does the job very well.

moving on, bought a couple of 10mm slip on spacers. fitted them on but only had 1mm clearance and it's definitely not enough. so i chucked the 25mm bolt on spacer back on and will be looking for new rims. due to the design of the konigs which doesn't have much concave to their design the +45 wouldn't work. now i figured out that a 12mm spacer will work best, so i'm wondering but not really certain if the +30 they have will fit. by measurements, i'm fairly certain it will. by design, i'm skeptical. compared to work emotions or bbs similar design, those brands have more concave into their design to meet BBK fitments. as an example, i could probably get away with evo x bbs rims at 18x8.5 with only a +38 offset just because of it's concave design..

but otherwise, the camber bolts made a huge difference to the set up i had over the weekend and it'll do for now. the wheels don't look ridiculously tucked out like i had it over the weekend without camber bolts installed..

Okay, I'm jealous. :p

I just installed EBC Green Stuff 2000 pads and their RK series plain rotors. It made a pretty big improvement, but they are still not as cool as Brembos.

^i was initially going to go down that route. but i wanted more stopping force rather than heat management..

i'll be looking forward to the next track day to see how these manage. will be running EBC yellow with them too. should definitely hold up downhill 180-80 without a problem. hopefully with the rears installed too..


anyone good with offset measurements/ wheel design care to chime in on the rims issue? i know it's different with every rim design too, if it's any help, the distance from the rotor hat to caliper edge is roughly 40mm. funny thing is, looking back, i knew these wouldn't be concave enough but i was pretty desperate to get rid of the stock 18s..

That's a whole lotta stop for a itty bitty car. I like it though.

thanks! but not when you're on a track and you're chasing that 50-100m braking zone, downhill from 180-80 for 7-8 laps. it's more track application that street of course..

I'm excited just thinking of taking turns at those crazy speeds...

Maybe, after a few professional driving classes, I can test mine out on a track too someday.

Really test the cars boundaries and the work I've put into her.

The EBC yellows are a perfect choice for your setup too. I'm really digging my EBC green stuff pads and the yellows are like twice as aggressive as they are. They should have a real good initial bite.

Please keep us posted once you've tested them out. Rims and a BBK may be a future mod for me. Reduce some weight with performance rims and get more stopping power with better looking calipers.

For this big caliper there are far better brake pads than EBC Yellows for track application!
