Massive - Two-piece rotors for the 280x22mm kit

[ikkitousen]

Okay so what I guess I am not understanding is the purpose of the hat?
I mean I had free floating rotors on my R6 and I thought the concept was the same. More play in the rotor means less drag on the pad and the caliper decreasing the enertia lost from the front wheels not spinning freely.... Did that make sense?
Am I trippin and these are not a "free floating Rotor"?

The idea in that two-piece disc is to keep weight the same as a one-piece rotor, but to increase the duty and performance by having a lighter hat to balance the beefier disc.

I guess I am gettin my parts confusededed. I guess this would be more equivalent to a two piece crank on a BMX bike. - It's the "two-piece" that threw me off. Seee who says you cant teach an old... NM I aint that old.

I'm pretty sure you can count me in for a 300mm set. Just gotta run the numbers.

DAMN CONFUSEDEDEDED!!!

@ 2002Maniac - Thanks for the good word. Indeed, the rotors can be used on VWs as upgrade. Providing the hats have the VW 65mm center bore and the proper setscrew location. It think that the idea was to catter to as many peoples as posible. RX7-swaps. Dynapro swaps. VW guys. And the Mazda Miata guys. A few local racers have asked for better brakes. Great handling car, good power if turboed, but lousy brakes.

@ Ikkitousen - The purpose of making a two-piece hat is simple in this case. There's no real 280mm one-piece performance rotor available. And the VW discs have the vent opening toward the outside, meaning you can't air duct them. The only VW disc that had the inward venting is the RB rotor that costs $85usd each and is not strong enough for all-out abuse. A two-piece rotor will also lighter than a one-piece disc. Or at the same weight, it will be stronger. I made sure to get heavy duty rotors with directional vanes to help promoting cooling. The vanes, if directonal, really help circulate air as they work as a turbine. I did some testing, using the same rotor on both sides of my car, with one side being properly oriented, and the other side being wrong. Until the rotors would reach full heat, the car was violently pulling to the side with the wrongly oriented vanes because that side didn't cool properly. Until both sides raech full operating temperature and the pulling was felt less.

Two-piece rotor doesn't necesarely means it is floating (in the hat, or in the disc). Making a floating system costs more because of the extra hardware and machining. Expect $250usd more for a float-in-the disc (including $100 on discs each time you change them), or $150 for a float-in-the-hat, using regular discs and custom drive-pins.

As to your assumption that floating disc reduce drag, I don't know where you got that. Maybe it is true, but floating systems allow for independent expansion of the hats vs rotors, and a reduction of oscillation of the disc. If a floating disc is what you want, then you can use the 300x32mm kit. ;-)

There's a kit for every budget and every sinple application. From 280x21mm to 332x32mm. And I expect the new two-piece rotor to increase the duty and clearances of the 280mm kit, just the same the Heavy Duty rotor increased the abuse the 300x21mm kit could take over the previous Ultra LIght rotors with sraight vanes.

brakes.....

Lee......I was wondering the etiology of " Massive"........is it related to your BBK business...or is it more a personal moniker?..hehe


ok...on a more serious note......


.did I miss what the costs will be for replc'mt rotors after the initial purchase of the set up.....? I assume the hats remain re usable?......for ever?.....or how long?.....sorry if I missed it, Im just excited.

Hi Joel

When I first started producing 2002 kits, 10 years ago, people were calling the 300x32mm rotors, massive. Like in huge. So, the name stuck.

Replacement cost of rotors is as stated in my previous post. And you can buy Massive's custom heavy duty rotors, or get Wilwood's lighter duty units. So basically, you are not stuck with me. And yes, hats are reusable. Being anodized, they will widthstand harsh conditions.

lee...thanks....found it.


I just pm'd ya......so not to get off topic.

Is shipping included in the $899 and can the kit be had with compound E pads? What color will the hat be? Gold hopefully?

[Massive Lee]

Shipping is not included. Expect $50 by UPS ground.
E compound pads can be substituted at no extra cost.

So is the $399 introductory price for the slotted heavy-duty version with directional vanes? I would like to see some pictures of the finished product, but you can most likely count me in.

[Massive Lee]

The slotting is optional.

Price?

I had a Massive front brake kit with Wilwood Calipers and slotted rotots on a E30 I sold a year ago. The kit was beyond excellent: great cooling capacity, great bite in street and track use, NO fade even with street pads. I should've kept that damn car. These brake kits are a great deal: soon to be on the red 325is I'm building now.

[Massive Lee]

Slotting is $15usd per disc, which is my cost almost to the cent.

BTW I got my price on manufacuring the hats. They are $10 more per unit than expected, but I will keep the prices as listed in the previous post. They are more expensive than expected because there's some extra machining than is not done on my other hats.

If a distributor has cheaper discs and wants to buy the hats in bulk, then let's talk business ;-)

Can someone confirm if this new street kit will fit in a BBS RS001?

[Massive Lee]

Alex, I suggest you download the template and test it against your wheel

Is this the profile for your new Street kit with 2-pc calliper? You mentioned in your first thread that there is supposed to be better clearence.

Apologies if I misunderstood, just checking.
