yes, they have a great rep and if you're a pro team or have that kind of money and only the most expensive will do then you don't have to wait on a kit, you can build your own

but if I was in that situation it's likely I'd be running a Porsche and not an RX-8, for the majority of us RB is more than sufficient, to each his own though ...

 

Spoke with Chris today and they are in production on this kit! Can't wait to get my hands on this thing! I'm split on whether or not to get the drilled/slotted or just the slotted rotors...any thoughts? The car is street driven, but will see some significant track time.

 

"Stalled AP Racing Kit Development"

Are you saying you stalled your car while racing?

 

haha, no the development of the kit had stalled but is now in full swing!

 

oooooh, okay... i understand now

 

http://www.porterfield-brakes.com/

They make brakes for racing applications and will have no problem making a set for a RB application. Cutom brakes are their specialty. In California.

Still hard to justify 3k for brakes when there is only a weight reduction.

 

The RacingBrake pad shape/design is the same as the Nissan 300ZXTT (Hawk HB178), you can pretty much get in most compounds, RB recommends Hawk compounds and offers HPS, HP+, Blue 9012, HT-10, and DTC-60 for their front caliper with appropriate matching compounds for the OE rear caliper

I personally don't like Porterfield pads ...

 

Ok..whoah..

0-1400d pads? w

Something is not being told to you..something big.

No worthwhile street pad has that temperature range without some huge drawbacks.

Ask for a fricition chart, the pad might make peak friction at maybe..700d, and nearly nothing at 1400.

A street car will -never- achieve over 800d unless you went out to purposefully abuse them, or perhaps a track day might see 900-1000d, but only if you are either really good, or have bad braking habits

I could go into at least a dozen reasons why juding a pad by temperature range by itself is nearly useless, but i'll save that for a PM if someone wants to know.

And for those who believe if you buy a custom brake kit youre stuck with custom pads..nope. Everyone's custom "kit" uses someone else's calipers just with their name.

PM me..I sell brakes, I have for 8 years. If you dontknow what you have and the supplier wont tell you, all I need is a fax of the backing plate tracing.

It'll be a standard pad...nothing hidden.

 

Why do they -only- recommend Hawk? There are at least 3-4 other _major_ peformance brake vendors. Not counting the multitude of other "vendors" that relabel major vendors and call their own.

IMHO, in nearly all applications, there are way better options than Hawk, Hawk has not innovated much in the last 8 years, while others have.

Some people are happy with Hawk, and thats fine, but..there are alternatives, and in some cases significantly better ones.

 

I see no reason to switch to different caliper for the RX8. Unless you are producing a substantial amount of horsepower it is not needed. If you like the looks great; that could be reason enough for some.

Agreed. Ive burned up some fantastic track times at Sears Pt & Thunderhill here in CA on stock brake hardware and not experienced fade whatsoever.



Replace the stock pads with a suitable one based on your needs. I use Hawk HT-14 on the front and Blues on the rear. They are excellent track pads and provide fade free stops with repeated HARD use.
---
I have had some people try Raybestos ST41 on front, and Porterfield R4 as a friction-matched combination on a number of cars in the 8's performance range with great results..mostly not eating rotors anymore, which is a huge Hawk problem. Granted that the 8 wont fade that Hawk combination either...but the Blues dont make enough good friction..although they ARE the right pad for the temperate range in the rear..in the Hawk line.

Put on brake ducts to provide clean fresh air.
---
And proper ones..the diff between good and bad ducts is huge.

IMHO spend your money on some track time concentrating on learning car control it will make you a better and potentially a safer driver.
---
Preach on...

I have tracked C5 Corvettes, STi's, SCCA GT2 RX7, and others. The RX8 beats them all in the braking department
---
Amen.

Bottom line the RX8 has EXCELLENT brakes it would be very difficult to improve them in any except the most extreme situations.
---
Ive been over that before as well, anything larger is just bling making up for poor driving habits and _bad_ pad selection.

PM me if you have any Qs

 

or dropping considerable unsprung mass off for racing applications .... otherwise I'd agree that brake kit on the RX-8 isn't going to offer much of an improvement

I've experienced some of their competitors innovations and went back to Hawk. Frankly, I don't consider buildup and sh-tty service innovative. Hawk does have several new superior compounds (DTC motorsport line), the issue is getting them on the pad shape you need because they won't build any less than 100 sets of any particular shape. As for why RB recommends Hawk only, that is explained on their site. They have Hawk make special runs of the DTC compound for their pad shape.

 

Since im not a supporting vendor, I dont wanna get too deep into the "who" factor, but there are more vendors than just Hawk..that are pure vendors. At least one of them can outwork any of the DTCs, and I have racing teams able to run an entire season+ on a single set of pads, with way more fricction efficiency.

Many others rebadge exsting product to their own unfortunately, and give real manufacturers bad names as people fear experimenting, and thats very understandable. If you like something, change comes hard.

And..I can provide any shape required in Qty of 1, easily enough, with very few exceptions. But since Hawk uses fully bonded (non holes in the backing plates) pads, not a problem. Have been for years.

 

^^ Interesting choice I'd give them a try too .....get dirty !

 

Gimme till Tuesday/Wednesday (travel and stuff) to confirm.

 

I wouldn't try them try them at the track dannobre, should work for my application tho ...

I can take the Black compound as an alternative

 

HT10's or Blacks for me....... HB178?.564 Front HB378?.565 Rear

 

I wouldn't recommend Black for you

 

You can always go here: http://www.porterfield-brakes.com/

Alot of Miata guys use them along with race teams.

 

hawk blue and black, will damage rims, and they don't stop with out warming up.

 

not true for Black, it has been used quite successfully for serious autocross, it is officially rated for 100 - 900 degF, dust fines are typical of a motorsport pad, needs to be cleaned after each use

I agree that Blue is a track pad and the dust fines are murder on wheels

 

I think I can get the 10's from RB....I think I'll try them. The HP+ stop OK on most tracks...but they wear out very fast when they are smokin hot....

Team...whould you recomend 10's all around ( can I even get them in 378's??) or 10's front and blacks/HP+ on the back??

 

Black is not a offered in HB378, they have HT-10, Blue-9012, HP+, HPS, and Ceramic

for the RB 4 piston caliper (HB178) they have DTC-60, HT-10, Blue-9012, HP+, and HPS
