Massive - 280mm x 22mm BBK - $660usd

[Massive Lee]

You nailed it. Having to apply a lot of pressure on the brake pedal can be tiring, and result on the feeling that you have lesser brakes. 25.4mm MC on a small caliper pistons will require much more work than a regular 21.8mm. The smaller MC will require 25% less effort. Pads also affect how much pressure is required to get to a stop.

Yeah, I need to source an IX master. Pity they're $1200...

[Massive Lee]

The iX master is 22,2mm and costs 190 Euros, or less than $250usd.

[Fidhle007]

Where are you finding that price? That's great to know about, Bav Auto lists it at $1192.95 and our wholesale through worldpac isn't much better. Real OEM shows it cheaper though so maybe it's come back down to normal recently?

French aftermarket

Brand is Mafix

BTW what is so special about the iX MC compared to a straight e30?

I don't know if it's different in the US (I can't see why it would be though) but the IX booster uses the later style angled studs rather than the horizontal ones on the regular booster. If I'd used a 320i booster on my swap I could have kept the original master but I went with an IX booster and 540 master.

Rockauto has a Beck Arnley for $ 160 and change. I just got a ix master.

brendan e36 masters bolt up to IX booster, I'm running 95 m3 master which I think is around 25mm. IIRC 96-99 was like 1mm bigger than that, and regular e36 around 22. realoem knows this stuff though, and e36 masters are easy to find used. Hell I think I have one off a 93 325is if you want it, trade ya for that box of goodies you already sent me :)

[Fidhle007]

Nice! I need to send you a check anyway... I'll try the 25mm MC I have on first and see how it is, I can still lock up the tires so I can't imagine too much more power would be good but I like the feel of the IX... I put four studded snows on it yesterday and went and played around in the snow, I was like a kid with a new sled.

Street kit wheel fitment - BBS RM et33 and Dotz 7x15 et28

Lee, thanks for sticking with this and thanks for the tip on the ix booster.
For what it's worth, I've heard anecdotally that iX's have slightly different front-rear bias. Maybe slightly more rear, but I could not find info to back this up.


I'll be watching Brendan’s progress closely, and like him, am interested in a front – rear combo.


I checked brake clearances for a few wheels, using your templates:

Wheel: BBS RM012 ET33 15x6.5 (in stock form; VW GTI stock rims).

Street kit (Corrado disk 22x280 mm, Dynapro calliper), no spacer:
~1mm clearance on front. Lots of clearance to barrel.
With ~1.9mm spacers to match thickness of BMW disk at wheel bolt area, clearance would be nearly 3mm. (This assumes Lee’s disks have same wall thickness as stock Corrado disk at wheel bolt area). Due to the champher in my wheels, with any larger spacers and I would loose the hub centric fit, unless I went with huge spacers with hub centric section e.g. H&R 15mm.

Sport kit (22mm x 300mm UL rotor and Superlite Caliper):
Not a chance of fitting even with huge spacers.



Wheel: Dotz ET28 15x7 (11 spoke):

Street kit, no spacer:
<1mm clearance on front. Lots of clearance to barrel.
With ~1.9mm spacers to match thickness of BMW disk at wheel bolt area, clearance would be something like 2mm at the front.

Sport kit (22mm x 300mm UL rotor and Superlite Caliper):
Not a chance of fitting even with huge spacers.

I'd like to know how BBS RA's fit:
Anyone tested these? Mine are a typical VW size (15x6.5? et 30mm ?) but are in storage where I can’t easily check.


Lastly, here is a hypothetical kit:
Dynapro callipers onto 22mm x 300mm UL rotor from the sport kit
This assumes pad and disc size are compatible - I did not check.
Estimate only:
Both wheels would come close at the caliper outer corner, but with around 2mm of clearance.

[Massive Lee]

Thanks for the info.

People who purchased the 280mm kit will receive free 3mm spacers. They will be available separately when purchasing a kit. But they won't be sold outright.

The Sport kit used to be available with a Narrowmount Dynalite. If you wish to buy one with Dynalite, then just specify you want that. It will take a a week more for delivery as we must order the Dynalites, while we have Superlite and SL-R calipers in stock at all time. If anybody wants to have templates for the Sport-Dynalite kit, just PM me. I do have a couple of Sport kits in stock.

^So does that mean you could do the Sport kit with the Dynapro6?

My vanity would really like 300mm rotors behind my 17s.

Sport kit with Dynapro6 would require to make new mounts. The Dynalite I was talking about are the ones with narrow mounts (3.5" instead of 5.25") and can be substituted to the Superlite (same 3.5" mounts and offset).

The Dynapro6 cost about $270usd and I think they are too much money for the bling. For $80 more, you can get a real race caliper such as the SL6R.

BTW I am all ears to vanity and bling. I can make custom orders if it is financially viable. Which means I could do a batch of 13" kits for e30s if I have 5 minimum orders. But I won't be responsible for organizing that group. It would be up to you to come up with the 5 firm pre-paid orders. I can even make you a 14" kit if you like bling that much...

On another subject, but still related to the title of this thread. What if I came up with a rear kit that used the stock rotors (that you already have) and removed the pityfull sliding caliper, to replace it with a 4 pot Dynapro? Basically, I would supply the calipers, the adapters and hydraulic fittings. You can use the front kit alone, and then install the rear one later. The rear calipers would have 1.00" pistons, which is a great match for the front 1.38". A stock e30 MC would be great too. No need to change it. I can see if I could get slotted rear rotors to match the front slotted ones.

I'm all about this idea! I like vanity too but my wallet likes practicality... :)

I have an adjustable proportioning valve already installed on my rear line but I've yet to adjust it as my fronts lock up long before the rears do (I've actually never gotten the rears to lock.) Would you recommend against slightly upsizing the rear pistons (I have a pretty stiff car) and correcting with the prop valve if conditions require?
