Ultimate Frankenstein: 'OEM Big Brake' kit.

[HenRoc]

Ok so I've been getting a few questions here and there on how I was able to get a set of NSX calipers for my 5 lug conversion, and also I started browsing and no one seemed to have covered the NSX upgrade and what was required for the front end of the car as far as rotors were concerned so I did some digging and came up with this:

Ultimate Frankenstein OEM ‘Big Brake’ kit:

I listed all the parts list for the 5 lug conversion with part numbers using OEM Honda / Acura part numbers.

Front Lower Ball joints / Spindles/ Wheel bearings and hub:
1995 – 1998 Honda Odyssey
Hub bearing part number: 44200-SX0-008
Right front knuckle: 51210-SX0-902
Left front knuckle: 51215-SX0-902
Ball joint: 51220-S84-A02

Front Pads and Calipers:
1991 – 2005 Acura NSX
Caliper Assembly (Right): 45210-SL0-023
Caliper Assembly (Left): 45230-SL0-023

Front Rotors:
1992 - 1995 Acura Legend GS
Front disc : 45251-SP0-E00

*These are the only rotors that are compabitible with the NSX calipers and brakets since they are 28 mm thick hench the 28T stamp on the brackets.*

Rear Hubs:
1997 – 2001 Honda Prelude
Rear Hub (both sides are the same):42200-S30-C51

Rear Rotors:
1998 – 2000 Acura Integra Type R
Rear disk:42510-ST7-R00

Rear Pads:

1990 – 1993 Accord EX
Your own Accord VIN tag since you will be reusing the rear caliper and pads. If you do a rear disc conversion be sure to snag the VIN for any future OEM parts purchases.

- The real down side is that the NSX calipers are VERY expensive and very hard to come by (I found mine for a great deal 4 years ago when I owned my 5th gen) everything is fairly priced..but I posted the part numbers up anyways just to help some of you guys out.

Another note: the rear abs sensors HAVE to be spaced out in a way that they will not hit the hubs in the rear. I deleted my ABS so I wouldn't have to worry about this little obstacle but for the ones who want to retain the ABS, you will need spacers (washers work).

I bet the guys that live near junkyards that see these love it. Here in podunk illinois I might as well see a dodo bird.

It's not impossible to find NSX calipers that have been removed from modified NSXs in favor of upgrades. You just have to look for it.

I don't know of any full big brake kits for our cars now... not ones that include huge calipers (there are some that include larger rotors and caliper relocation brackets.) Aside from custom fabrication, this may be one of the best big brake options available.

Now, it IS possible to do too much to the brakes, making the car unstable under hard braking. If you want to pursue a big brake upgrade of any kind, it is wise to research first.

There is no point i using NSX calipers when you could use legend type 2 calipers which are slightly bigger and way cheaper.

What is the piston arrangement like on the two calipers? Size isn't everything.

Well yeah this is true.althought it's hard to find them remaned. I looked for awhile before I stumbled across my set back in 08.

Used ones on eBay were going for nearly $250 just for one side. I know Farad (gold SE I can't think of his user name) had come across a set on a wrecked NSX for $200 flat.

But weren't the Legends reverse mounted when you installed them on the CB chassis? L on the Right side and R on the Left side? I never liked the idea for that.

Bigger piston in the back..smaller piston in the rear.

Trust me. My car stops on a dime. You guys may not believe me..but there's a thread on Honda-Tech that discussed this upgrade..no one had really done the 5 lug swap WITH the NSX calipers...it was always rumored but never tried.

I know the Accord guys were rocking them with 4 lug setups (StickyDil had this on his old Accord back in the day).

Once I posted my setup on my old 5th gen, I got an email from this guy name Jason Katman who happened to work for JHPUSA , asked me TONS of questions on the setup and how it felt braking wise.

It never messed with the braking bias at all, and I've locked up both fronts in some pretty intense cases never noticed anything major fail.

BMC stays the same as well.

Figured I'd give something back to the forum.

[deevergote]

Yeah, I'm not doubting you... just saying that depending on the use of the car, it's important to understand WHY you're doing an upgrade, and exactly what that upgrade is going to do. An imbalanced large brake setup could be worse than a smaller setup on a track.

[Jarrett]

I would hardly call this the "ultimate" OEM brake upgrade. There are many better calipers out there like the Brembos on the TL/RL/DC5 Integra Type R/EP3 Civic Type R. They're not all the same but all of them would offer better stopping abilities than the NSX brakes. And the Legend rotor is only an 11.1" rotor still. There are bigger options available there too. It's a nice gesture for you to spell it out with part numbers for everyone, but I think there are better setups to be made.

[HenRoc]

I would think TL's are harder to use since the mounting points are different and the line isn't a rubber line but a metal line.

Damn..I went down in a hail of bullets.

[deevergote]

Nobody went down. Defend your setup, man! If it's good, and you know it's good, you shouldn't have a difficult time saying WHY it's good.

[Jarrett]

I didn't say it wasn't good. It's certainly good. I just said it wasn't the ultimate.

And the bolt locations aren't different in location, just size. 17mm holes versus 19mm.

It's definitely different and unique, and it has what I think a great function
for a daily.

Thanks Mike

I completely forgot that USC had written this article years ago. It definitely makes me oppose that Legend mod allot more now.

[N9netwoAccord]

Speaking first hand having driven this car, and believe me I've driven very fast cars with upgraded brake systems (Wilwood, Brembo etc) This car is very competive with the expensive set ups, Henry, I'll vouch for you, this car stops extremely well for the set up.

He misses a key point that voids the whole argument

That you can install them properly and bleed them before you bolt them to the car. Once they're bleed they will work the same regardless of bleeder location.

its not even hard to bleed them properly


And to be honest i doubt installing them properly or "improperly" would yield any difference in braking.


Honestly that article is a bunch of opinions anyways. There are no facts to back up that one way would not work as well as the other. No tests were preformed.

And the whole part where he refers to it as a big brake kits? Give me a break... this isn't a big brake kit. For fucks sake the car comes stock with those sized rotors.
