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

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?

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]

Yes, the fixed limiter is gone. :-)

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

[der affe]

interested in both too!

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?

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.

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...

[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]

Currently working with a supplier to find/make a rear one-piece 280mm rotor.

In the back, it is an easier fit on a 300mm than 280mm disc.

The Dynapro (widemount) is the evolution of the Dynalite (widemount). Not to be confused with the Dynalite (Narrow mount) also called BNDL. The later has the same mounting points as the Superlite caliper. which is why the 300mm x 21mm Sport kit can be ordered with Superlite or BNDL calipers.

How does the fixed pressure limiter work? I'm hunting down a braking problem and suspect something is going on with this valve, because braking feels normal at light pedal pressures but ramping up pressure, it gets all screwed up, locking the front wheels.

[Massive Lee]

Hi Fred

The fixed pressure limiting valve only affects the rear circuits. If you lock-up the front brakes too easily, perhaps your front pads are too grabby. Brakes don't lock-up by themselve. In the worst scenario, if the bias is way too much to the front, you will feel the car unstable on hard straight line braking. If front brakes lock-up easily, then just apply less pressure on the pedal...

Thanks for the clarification.

Anxiously awaiting your findings on the rear kit.

[Brian D]

Trying hard to be patient...

Have you received the brackets yet Lee?

[jackbenny]

Payment sent and in your paypal account Lee. Sorry for the delay. Also curious what you come up with for the rear.

Thanks
