for anyone who has upgraded the breaks for the rx8 what type of things or brands have u gone with...ie.. mainly calipers and pads...my uncle ordered ss break lines and brembo drilled rotors. but i dont know much about good caliper upgrades. if there are any...so any ideas thanx

Glyphon

well...there are some big brake kits out there for the rx8, that increase rotor size and up the caliper to 6 pot, but there is also debate as to whether or not these kits actually make any difference at all.

SS brake lines will increase pedal feel, and there are racing pads, but those those aren't recommended for daily street driving because they are much more abrasive and will wear the rotor out much faster. Also, in street driving, the brakes would never get up to optimal temperture for racing pads, which could actually cause them to perform worse than stock.

from what i've heard is the best thing for the rx8 brakes is moving to a different rotor, that will increase its ability to disipate heat, such as a cross drilled or slotted, but those benifits would really only manifest on the track.

the rx8 stock has an incredibly brake system stock, and as such is difficult to make improvements on. if you want to do some thing, go with ss brake lines, paint the calipers, and spend rest of the money else where. that's my $0.02.

thanx for the input the car is basically show and doesnt get driven much that will change this year and prolly never will see the track lol.

Glyphon

oh, then by all means go for one of the big brake kits. there are few of them out there, just do a search. they are great for show, and work fine for daily driving.

here's a link to one thread...

I think the rx8 stock brake arent that great when it come to high speed breaking.60-0 is exellent but when it come to braking 115+ they could use some help.They gave me a pretty good scar when braking after trying top it out.Would one of these kits help or are they ne other mods that ne one knows about

RacingBrake's RX-8 BBK knocks 24# off the front suspension over the OE brakes so it's not just a matter of stopping distance, there are other gains to be had like more even pad wear (longer pad life), high temperature endurance, modulation control at the limit of cornering adhesion, etc.

6-pot calipers are only beneficial for full out racing applications where the larger pad needs to last for as long as possible before needing to be replaced

if its for show go with the endless calipers they are absolutely gorgeous. you can see pictures on some threads here of a blue one from autornd. they fit both stock wheels and rotors i believe.

mattmanp5

ill check on the endless ones thanx...i found ap racing but they are incredably over priced

Does everyone agree that you could upgrade to the blue Endless calipers and then upgrade rotors at a later date? I love the pic of those rotors, I'm debaiting...

Endless USA said they need a 5mm spacer for the stock wheel but Hong Kong counterpart says they don't.

Endless caliper can come in a kit. Their rotor is good.

You need a racing set and a street set for Endless - they don't have good range for middle street/track.

Seidoya Makes good pads in Japan.

I went for AP racing caliper - they are not pricey AUD$2500 for the whole kit without rotor. I am getting Project Mu rotor and pads to suit them.

I have absolutely no clue what you just said.

But it sounds like you need new tires.

takahashi

My car stop better than a Porsche at 180kmh. It is all in your right foot.

Having said that a Big *** brake is good too.

supergoat

I don't want to ride with the person that needs bigger than 12.7in brakes on a street car!!

Winning 8

if it's for show I get the GREX 6 pot chrome, look too sexy for getting brake dust on it.

I am definitly on the RacingBrake bandwagon.

There product is top drawer....and there customer service is the best I have ever dealt with.

I have 6 hard track days on the two piece rotors....and they look like new

( well almost...the paint is all burnt off )

RPIRX-8

I just picked up the racing brake 1 piece slotted rotors (cash flow problems this season ). First track day is May 30th. First couple of stops were scary, but after I bedded them, jumping jahosephat batman, great stopping power. I'm anxious to see the performance with my Carbotechs.

fwiw RacingBrake only recommends Hawk pads for their rotors

most of those kits are overpriced/overrated, RacingBrake is a damn good choice for the money, I pity the fool that thinks they need to spend 2x+ more for Project Mu etc.

I've heard that as well. I'm reluctant to change because I'm used to the Carbotechs and love them on the track. They did, however, cook the set of rotors I had last year in 2 consecutive track days (adreneline racing rotors).

I am using Rotora cross-drilled rotors with Project Mu Titan pads for the track and stock pads for the street. The general idea is to upgrade the rotor with stock temp pads or upgrade the pads with stock rotor. To do both is a bit of overkill for the street and they don't get to optimum temps, as was stated earlier. Squealing like a pig and don't do much until they are hot.

Racing Brake one piece drilled and slotted bling bling here also with Hawk HPS pads, Goodrich stainless lines and ATE Super Blue - no track days yet, but the backroads aound Mt. St. Helen's sure were fun yesterday. The brakes were awesome indeed.

Great brakes also means less necessary horsepower to beat others on the track.

It also means your pocket hurts when you change brake pads, by the way what's the cost of the stock pads?

$113.58 for all four

I use Rotara slotted rotors too.

However, I use Porterfield Kevlar brake pads.
