What about M2's 4-wheel kit?
Michel

 

This is Jim we're talking about - he's been there, done that.

 

Been there, done that, keeping my ABS and using a 929 master cylinder, thanks.

Since no one seems to have a "comprehensive" 4-corner setup which includes a parking brake option, I think that I may just go with the RS/RZ brakes in the rear with a set of good ol' AP Racing CP5200 4-piston calipers and 13" rotors in the front. I can easily get Hawk HPS pads for both, and if I could get a slotted rear rotor to match the front, that'd be fine with me. I'll paint the rear calipers black to match, or maybe I'll get the red AP Racing kit from Stillen, although they come with slotted and drilled rotors. Not a problem for a street car, though, probably.

AP Racing front kit (red or black) - $2,499

 

I would be very suprised if M2 closes up shop. I am sure the subaru market will be viable for a while and while the RX7 market may have peaked, there seems to be new owners popping up all the time.
What other car can be had for around 10,000 dollars, throw a freshed motor in it, add a single turbo and go out and whip a viper at the drag strip and road course?
I am probably one of the older forum members and when people my age see my 7 they have no idea what it is, but if some late teen or 20 somethings see it they all know what it is and are fascinated by it.
I think this car will be around a while and the good shops will stay in the game.

Thanks for your input, sorry my computer was broken so i couldnt reply. I will most likley go with just slotted rotors if i can find them, i've read that they are more durable then the xdrilled ones. correct me if i am wrong though. As for pads i want to go with a performance pad like hawk hps. It isnt that much money to get the rotors and pads, plus some stainless brake lines. That should due me for now. Thanks for your help.

 

Now, Ric you're not the only thirty-something FD owner running around in a HOT TRACK FD

 

Well, maybe you don't want to *start* a rumor, but you've definitely given it some life here. So tell us the story!

 

That might be fine for track, too -- there are obviously some cars that use drilled rotors without big cracking problems on the track. The problem with the FD is the combination of the rotor size and drilling for track use. Bigger drilled rotors must be fine for the track. I am sure they would be fine on the street.

Anyone know anything about HP Racing brakes? Tom Ngo has them on his car (not that that's necessarily a good endorsement... I don't think he needs great brakes for car shows...) and I have to admit, they do look pretty cool, or at least the rotors do.





I sent them an e-mail asking for more details (pad selection, rotor size, caliper and color options, that sort of thing). It'd be nice if you could get a rear rotor to match the fronts that would work with the RS/RZ rear calipers. How big is that sucker again?

 

bros0000 is right on the money. Big brakes and fancy rotors won't make you stop faster, provided you can lock up the wheels (invoke the ABS) with your current brakes. Big brakes are primarily for reducing fade, increasing braking consistency, cheaper/bigger/longer lasting pads, and looking cool. Brake fade and rotor/pad life become an issue on the track, but the stock brakes are quite adequate for general street use and even some track work. Lots of people who track their cars still run the stock brakes, for instance.

Cross-drilled rotors in the stock size will crack on the track. I've seen a relatively inexperienced driver crack up a set of new drilled rotors on the track in one day. And it gets worse once you get better at driving. Since you are planning to do some track events, I would go for OEM-style solid face rotors, perhaps cryo-treated for longer life. If you get the track bug, you can always put on big brakes later. For now, you can save your money.

Oh yeah, I have a really great deal on the AP systems and with regards to the HP brakes. I can't say too much. I know that they just assemble them and can make whatever you want. But I'm not sure that this is a race engineered kit. I could be wrong.

I've been in contact with them for quite some time now about header apps for proteges and the brakes came up once. But I don't believe they have much of any roadrace credibility. Maybe drag racing as that's a lot of what HP does on the east coast.

 

Cool. I was hoping you guys would pop in. I figured he could get his functional needs without spending much money.

 

Are those 1-piece rotors on the HP systems? Interesting. 2-piece are better (weight, heat distortion) but those look damn nice for 1-piece.

The RZ rear rotors are 314mm (12.2") x 0.8", I think. Wilwood makes some rotors (slotted and/or drilled) in that size, as I am sure other brake parts manufacturers do, too. If you want to chase down some hats, I'd be in for a group buy. They wouldn't match the HPs, but they might make a better aesthetic match for the slotted AP fronts. They should be relatively inexpensive if the hats can be produced for a reasonable price. I think the rotors are only $40 or so.

From HP Racing...

"We can supply you with 6 or 8 piston calipers and depending on your wheel size up to a 13.5" slotted and cross-drilled rotor. The kit also comes with stainless brake lines and semi race pads, which at this point is the only option. The colors available are red, blue, or titanium. Retail on this kit is $1850.00 (6 pot) and $2459.00 (8pot)."

 

Seems to me, that while the styling of the HP stuff is great, the rotor pad combo seems mismatched.
The pad isnt using much of the rotor surface, why not use a larger hat and a "shallower" rotor surface.
seems as though it would save a bit of weight by using a larger alluminum hat and have a little less rotating mass in the way of the rotor.
Just a thought.

Well, to be fair, there are no pads installed in the red calipers in the picture above. I'm assuming that they extend some distance from the caliper. Then again, maybe not.

 

id bet they dont extend much beyond the caliper, My wilwoods didnt and the APs dont either. to far away from the piston, no force that far away. On my AP kit the hat has a 9 inch bolt circle and the rotor is 14 inch,leaving 2.5 inches remaning for the pad, just enough. the clearance is very small. Do you know what pad is called for ?

 

Well, I've had enough over-analyzing my setup, and I believe I'm just going to go with the Stillen red AP Racing 4-pot 13.0" combination in the front, assuming they respond and let me know that it's a 5200-series caliper. Hawk HPS pads are more than enough for my purposes.

In the back, I'll get the RS/RZ calipers and Hawk HPS pads, and see if I can't find someone who can source a rotor with matching slots. I don't feel like trying to re-engineer a parking brake setup, but it would be nice to have matching rotors front and rear. I just hope they look big enough behind 19s.

 

Everything you ever wanted to know about FD Rx7 big-brake technology is here! Your one-stop shop for information on the different big brake kits, actual owner experiences, prices, and vendors.

It's a good read for any FD enthusiast looking to match his/her "whoa power" with the "go power"!

 

Figured I'd throw in a couple pictures of Bernd Kluesener's rear setup... *drool*

 

And with an AP Racing 3740 caliper...

 

who makes the uprights?
what kind of disc?

thanks...hmmmm

I do have a spare set of caliper lying ard

 

They're modified OEM uprights. Bernd had the mounting pads made for him and welded on. The rotors are 304mm (~12.0") he said.

 

So what's the best price/vendor to get the '99 RS/RZ rear calipers and rotors from? I've got the parts list that was posted, but need to know who to buy from.

I am going to use AP Racing CP5200s in the front (13.0" rotor) with Hawk HPS pads, and '99 calipers in the rear, also with HPS pads. I'd like to find an aftermarket slotted rotor (they have to exist, right?) to match the front, and I'm going to get the red AP Racing calipers and paint the rears to match.

 

My apologies to Brian and M2 Performance. I was indeed told by an M2 Vendor that this kit was no longer available, but it now appears that this is not the case, and anyone interested in the 4-wheel kit or any of M2's other excellent products should contact them directly.

Again, my apologies to Brian and M2 Performance. I should know better than to repeat things I'm told without verification, no matter what the source. By posting this, I did a great injustice to Brian and his company, and I am deeply sorry for any inconvenience it may have caused.

Brian has expressed that he would be more than happy to discuss any such concerns with anyone interested in the facts.

Thanks
