NSX Brake Kit
Hey all... only been on this forum for a week. Had my CL as an extra ride since about 2016, but now looking to do some upgrades since my son turned 16.
It appears I am not the only one who can't find many performance upgrades for the CL. Brakes appear to be the case as well, based on my forum search.
I read that people go with Acura Legend or Acura NSX brakes as an upgrade. So searching for NSX brake kits, I see this, which looks like your basic upgraded brake kit: painted calipers, slotted and drilled rotors and pads.
So... is it this easy? Just buy an NSX kit like this?

Not sure if the Legend duel piston front caliper will fit a 99 CL 2.3 manual?
If they do, then you would need something like the below:
Go to rock auto and input Acura 1995 Legend and look for the duel piston calipers, if they have them in stock and you are certain they fit, snatch them up because they are hard to find in left & right for the front.

I didn't buy anything yet.
You said "if you are certain they fit". I'm not certain. I'm hearing on this forum that they just bolt on, but I am basing this on trust. I have more research to do to see what actually fits.
I will hit rock auto now.

Time needed to complete: approximately 1 hour and 30 mins w/ air tools. If air tools are not available, give yourself another hour.
Tools Needed:
• A set of metric sockets
• Ratchet
• A set of metric wrenches
• 36mm socket for axle nut
• Slide hammer (Preferably 5 lbs, rent this from a local auto parts store)
• 2x4 block of wood
• 3lb sledge
* If you don't have air tools, you'll need a large ratchet and a breaker bar
Parts List:
• Front calipers from the Legend GS Coupe/LS Sedan or NSX
• 25T caliper bracket from the 5th gen Accord V6, Accord Wagon, 4th gen Prelude VTEC, 3.0CL or Integra Type R
• Rotors from a 5th gen Accord V6, Accord Wagon, 4th gen Prelude VTEC or 3.0CL (ITR rotors would need to be drilled to 4x114.3)
• 2 separate brake caliper hardware kits. 1 for the Legend/NSX calipers and 1 for the 25T brackets.
• 2 sets of brake pads.
The "25" in the 25T caliper bracket is the width of the rotor in millimeters. The 2.2/2.3CL have 23T brackets. If you buy a loaded Legend/NSX caliper, you'll receive 28T brackets. The 28T will work if you shim the bracket. If you have a 3.0 CL, your brackets and rotors do not need changed.
Best place to buy the brackets is from rockauto.com. Advance Autoparts or other chains will charge you about $80. At Rock Auto it came to $40 with shipping.

Maybe you can aid smaiguy in his quest to have duel pot front calipers for his 1999 Acura CL 2.3L?

Sorry for the late reply. I thought that I locked myself out of my account, but I was able to get back in.
The Legend/NSX 2 piston brake swap is pretty straight forward for a 98/99 4 cylinder CL. To keep it simple, all you need is the rotors and caliper brackets from a 98/99 3.0CL and the Legend or NSX calipers. Nowadays, you'll probably have much better luck finding remanufactured Legend calipers for a reasonable price than a set of NSX calipers.

As mentioned, it is direct bolt-on meaning even the factory 2.3CL brake hoses fit properly.
The result is an approximate 10% increase in front stopping torque (very noticeable). This eliminate warped rotors due to panic stops and extends the life of the pads.
Another plus is that the braking system of 3.0 is exactly the same as 2.3 with the exception of front calipers and rotors. Additionally, the caliper piston diameters are the same and no proportioning valve or master cylinder changes are required.
There you go. That's how you do it without encountering a bunch of headaches or causing poor braking characteristics.

So I have. A 3.0 cl premium (not if that matters,I don't think), but are mine still single piston or dual? If they're single, could I grab the calipers from the legand/NSX, still using the 3.0 brackets and put them on?
Good luck finding the duel piston legend or NSX calipers.
