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

[z31maniac]

So probably more like $1300-1400? Still a very good price for what would seem to be a phenomal brake upgrade for all but the most serious track/race cars.

So fitting the Dynapro to your 2 piece 300mm is even easier than using the 280 Corrado rotor, or did I misinterpret?

[Massive Lee]

So what do you think? $1000 for street kit with rears? That too optimistic?

Too optimistic. That will get you the front kit and two rear calipers. No caliper adapters, no hydraulic fittings, no pads, no design of the bracket.

As of now fitting the Dynapro to a 300mm disc is very easy. More involved for a 280mm. Need to find a solution for the stock 256mm. Maybe another clamper...

I know i had to pass the GB until the holiday season passes... but I will def. be purchasing this BBK from you as stated before. HOWEVER, if you do make a rear caliper only kit as well and both are priced well... i'll most certainly pick them both up. Haha... i'm gonna need some BB for those 300+ ponies i cant wait to drive.

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...

It'd be easier, if I really wanted that kind of bling, to just pay you whatever high cost a one-off mount would be than try to get any of these cheap fuckers to buy an expensive brake kit like that. And one that would require 17s with lots of brake clearance.

However, you're idea about the upgraded rear on the stock rotor is good.

Especially since there are a few options for E30 rear rotors correct? Don't necessarily need to be racing brake brand.

So what do you think? $1000 for street kit with rears? That too optimistic?

[der affe]

interested in both too!

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.

Guaranteed sale from me. :D

[Fidhle007]

Yes, the fixed limiter is gone. :-)

[Massive Lee]

With front 1.38" and rear 1.00" you'll get a great bias.

BTW you mentionned you have a prop valve installed. Did you remove the fixed pressure limiter before installing the adjustable valve? You CAN NOT have both in line. Removing the fixed prop valve will hike rear pressure by close to 50% when mashing the brakes.

As soon as hydraulic pressure reaches 375psi, rear pressure's progression gets reduced by 33% compared to front.

[Fidhle007]

BTW For people who have enquired about a 4 pot caliper to upgrade the rear one, while keeping the stock rotor. Hmmm... Not physically possible. I must find a 280mm rear disc with a 160mm handbrake drum. I doubt it will come from a VW as they have very different rear set-ups. Basically, bearings are part of the rear discs.

Wait, did you figure out how to make this happen now?

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?

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

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

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.

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.
