Porche Brakes for NSX?

710 said:
I toast a pair of rotors every time I go racing in the hills. I have to bleed the brakes there too.
I have stock 91 brakes, the calipers work perfectly, the rotors are true, I have tried Honda rotors and several aftermarket rotors. Tried different pads too. All toast.

Hi 710 :)

I read that you are still having as much fun with the NSX as before.
I was wondering what you have done with your brakes thusfar.
I put on the Stoptech Aero-rotors myself, but in Daili's Axxis brakepads and put on bigger air deflectors and had tons of fun with zero problems at Spa with it. I am going to put on SS-lines this year to see if it makes much difference.

One set of 4 997S calipers, folks sell them pretty reasonably when they up-grade to ceramic brakes, got mine with 25 miles on them.:biggrin:

Then:

Custom hats
Custom rotors
Custom brake lines
Custom caliper mount brackets.

Helps to be a machinist...

Any one else interested in this, I can do 2 almost as easy as on set...


How much for the brackets and lines?
I can get the calipers readily.
You can PM me if you like.
Thanks

I've been running the Movit BBK setup for several years now. At the time, it was an upgrade from the Lotus caliper brembo kit I had picked up from Dali about a year earlier. Let me say, this was a BIG upgrade. BEWARE: This kit requires massive backspacing to accomodate the calipers. I run HRE 547's and they BARELY clear. I have test fit everything from Technomagensio's, Enkei's and Forgelines and none were even close to having the room for this kit. Having said that, the kit is great on the track. I've never had any fade issues on the track. The pedal is consistent and the brake torque is excellent. A note, Sebring is my home track and is notoriously hard on brakes...this kit has seen many track days there with no issues. For those heading to NSXPO 2006...make sure your brakes are ready for this track!

Hi MvM, hoe gaat het daar boven?
I had to wait till I found bigger wheels before I can install the bigger brakes.
I finally decided on what bigger wheels I am going to buy. Compomotive http://www.comp.co.uk

6 spoke, 17” front, 6 spoke 18” rear
But they are too wide, I will get the wheels narrowed in Germany. I want 6.5 or 7 wide at the front, 8 or 8.5 wide at the back
They are the closest I can find to the Technomagnisios (sp?). They come in lots and lots of offsets so that’s good. Strong too. Good for the roads here.
Compomotive’s website sucks, if you visit there, let me know if you need help navigating, I finally figured it out.:confused:

Then my clutch T/O bearing went or something (62,500km on the clutch)(39,000 miles) on the stock clutch. Not bad I guess.

So I have delayed getting my wheels, while I try to find the time to change the clutch. And I have no money for the wheels now.

That brings me to your question:
I thought I would give the HiSpecs a try on the NSX.

http://www.hispecmotorsport.co.uk

I used their Monster (not Mega Monster) 6 pot calipers

http://www.hispecmotorsport.co.uk/monster_6.htm

and discs on my Escort Cosworth and they work perfectly for 3 years now. The discs are a good price, probably because they are inferior quality, but I have not had any problems with them in the hills in France or on the Nurburgring. Those are the same hills and circuit that cook my stock NSX brakes all the time. 3 sets of NSX discs in 1 year! Shite.
The calipers are also a good price but you can wait for a zillion years before they actually deliver them.

So I now have a pair of HiSpec Mega Monster 6 pot callipers with adapter kit

http://www.hispecmotorsport.co.uk/mega_monster.htm

and I got their discs, bells and adapters too. These will need 17” wheels on the front.

The Mega Monsters use standard AP brake pad size CP3894D51 (152 x 80 x 18mm)
I have disc size 330mm for the front..
I also got 358mm discs for the front but I think they will might be too big. I will see when I have the wheels.

I got bigger rear discs too, 328mm, but will use the stock NSX caliper.

The discs are grooved (curved groove). I considered getting the drilled discs, but they were not in stock. Wheels will be black or gunmetal, so I got black calipers and plain aluminium coloured bells.

Glad to hear that the Spa circuit no longer cooks your brakes now with your setup! The bigger brakes feel much better, don’t they? So now you can brake a little better before Eau Rouge without sh*tting your pants as much, hehe :biggrin: (hey, I do)(brake, I mean)...(and sh*t too).

Nice on the NSX, I’ll bet. Especially in the pissing rain at Spa or the Ring! Much better feel, eh? The brakes, I mean, not the sh*t. That feels the same as usual.:tongue:

When I put the HiSpec on the Cossy, what a huge difference! Well the stock brakes were very bad on that car, much worse that the stock NSX’s. No comparison, the NSXes stock are much better than stock Cossy’s. (just being clear to avoid that BBQ feeling after being flamed! :smile: )

What size wheels and discs do you have now on the front of your NSX?
Next time at Spa you should get a ride in Gerard’s car on the circuit. With the racing tyres and big brakes. Talk about throwing the anchor out! :biggrin: :biggrin:
Are you coming on the NSX ride in the Ardennes in April?

Brembo's suck. In every Best Motoring video every car that they track with Brembos begins to experience severe fade after a couple of laps. Remember the Battle of Motegi video? The reason the Modena and the 996 finished way back in the pack is because they couldn't brake for the turns after a short while.

If you're going to upgrade the brakes the only serious contender should be Stoptech. They're less costly than Brembos as well.

God, I'm opinionated!

Ya, a guess those GT cars running in LeMans chose to go with Brembo brakes because of the severe fade.

As you may know NSX-Racer uses 993 tt brakes on his car but it has to be said that he is one of our more serious track rats. I seem to remember some video of him keeping up with an Enzo. Some of the quickest NSX guys at my local track have upgraded their brakes and very little else. So although the OEM brakes are more than adequate for the street, when it comes to serious track and I mean serious track use the brakes tend to be one of the first upgrades along with tires.

Regards,

I use the same BBK (911 TT from MOVIT) as NSX-Racer for years now. These brakes are perfect for track and street. No fading at all. Not even on fast tracks like Spa Franchorchamps (Belgium) and Monza (Italy). You can use the original Porsche pads which are even cheaper than OEM NSX pads. For street use these pads don't need to warm up like most racing pads do. So they won't eat your discs:biggrin:

I just finished my first 2 days a Thunderhill with the Porsche 997S front calipers, 32mm rotors mated with my Wilwood Dynalight 4 pot rear calipers. I ran out of time to get the mounts for the rear finished, because I needed to make 2 set of spacers for the fronts. I went to some Hawk Blue pads on the rear to balance better with the stock Porsche pads which came with the 997S calipers.

I am sold!!!! These things rock and I can't wait to get the rears done...

At the end of the second day, I was running better than 2:10 laps, clockwise, so a 135 mph to 70 mph brake zone for turn 15, the rotors never got above 980 deg. F! My old Wilwood set up would be seeing temps pushing 1200 deg. F with the same cooling set! This is huge in my eyes. The next test will be to see how long they last.

I will post some pics after I get the car cleaned up a bit.
 
I still have not washed my car, but here is a pic...still covered with Thunderhill grime and brake dust:rolleyes:

Porsche brakes are simply the best in the business... :wink:

Porsche combine a top line Brembo brake system with additional sealing for the street. So if you want the best of the best... NSX with Porsche brakes...

However for the track, I recommend the comptech brake kit with the Indy callipers. There is a lot less bulk and not as much sealing for superior cooling...

Next stop (pun intended!) is the ceramic ones... :biggrin:
 
Are you racing Porsches on the track with Porsche parts on your NSX?! Whats your next mod? a boxer engine? Couldn't you at least wipe off the Porsche lettering? Then you coming here talking how great they are?

For God's sake man, what if someone from the Porsche forums sees this thread... HUH?!!

You are embarrasing us.... :biggrin:

Not when you find out how much it costs to replace the rotors, and the fact that you will need to do so frequently. Which is why a lot of owners of the high-zoot cars that come with them are deciding to swap steel rotors back in...

That is my idea... great brakes...no headaches...easy to swap pads...solid pedal feel and fantastic performance on the track with out the fuss of 'no dust seal' race calipers.

I just took the best part of the German car, the brakes made in Italy...who should be embarrassed here????:rolleyes:

I feel no shame in thumbing my nose at them all, let the 'Porsche' stay!

I thought when ceramics were introduced they were superior because of their stopping power, but also because they would last a really really long time.

What happend there?

As for rotor costs. I just replaced the front two brembo's on mine..$329 each. Ouch. Luckily I got some help from our friends at SoS.
 
Hugh said:
Why on Earth would anyone want to do that? One of the reasons an NSX slaughters cars with up to almost twice the HP at the track is because of its superior brakes. Simply ugrading the stock brakes with steel lines and high performance pads is more than sufficient.

Actually Hugh, i have the Movit/Porsche brakes on my white car(93) and factory w/ pads and stainless lines on the black car (92).. I can assure you that the white stomps a mud hole in the factory setup... it is not even close. i know that alotle of people think the factory brakes are great but the brakes on my 4.6 BMW X5 are better !!

if someone is looking at gettin the movits i recommend them, picking wheels is an issue though, they are that big.

Yes I know how much a set of rotors cost. :eek:

I was impressed by the weight reduction and their temperature capability. But I didn't know about the wear rate... :eek:

Typically, how long would a set of ceramic rotors last?
 
Gerard van Santen said:
This BBK(motiv) is built around Brembo F-50 calipers, they are 64 mm thick from the rotor surface to the outermost face of the caliper. The 997S caliper is 60 mm in that same dimension. This reduces the space needed behind the spokes, or allows the use of a wider rotor(up to 34 mm) or both. The pads on the 997S calipers are 20% larger too, and the calipers are a mono-block making them more rigid than the older 2 piece F-50s. I am running mine with 6 mm spacers under the Tecno wheels, 10 mm spacers under my Simmons track wheels. Even with the 10 mm spacers and 235-40-17 tires I don't have rubbing on the fender liners, but it is close...

Works CE-28 wheels will clear the same way as the Tecnos, FYI. I tried a set at Thunderhill last weekend.

Don't you confuse the ceramic rotors with the carbon ones (used in the Formule 1 and last only one race) ?
