hey guys i have a mugen agbs on my 5 lugged integra, my rotors are long gone and i was wondering what other alternatives do i have other than the mugen rotors? could i possibly just get some blank brembo s2k rotors? or maybe itr rotors? someone please help me! thanks

 

Check out 1999 and up RL Rotors... They have the correct hubcentric hole for the ITR Spindle.
They cost $22-24 at napa (tell them you have AAA for discount)
If they bolt on, let me know... That will confirm my hunch without having to buy a mugen test disc...

 

just take your mugen rotor up to napa and just compare it to the TL...

 

I believe that the TL doesn't have the right center hole...

 

Yeah I know this is way back from the dead but wanted to share since I just dealt with this a bit.

RSX-S rotors don’t work on an ITR hub. The hub (OD) is too large to fit inside the rotor hat.

RL are 28mm vs proper 25mm width so might work for some, if pad width is manageable, but rotors are also quite a bit heavier.

Since I was doing this while doing a 5 lug conversion with 98 JDM ITR front knuckles and was doing bearings at the same time I did some checking. Turns out RSX-S hubs are a direct replacement for the 98+ JDM ITR Hub. This swap allows direct fitment of RSX-S rotors. I used Brembo blanks for this round but will try RacingBrake’s 2 piece when these are done. PM if anyone wants more details or photos.

 

I was asked to provide a bit more so here are some photos (more here: https://app.box.com/s/rdv8aeckid9jh1t5aw05imi27nd4mnv1)

Other speculation:
For USDM guys given the updated design of the RSX-S wheel hub and its compatibility with the JDM ITR knuckle I'd bet the extra diameter on the ITR Hub isn't really necessary. Nor is the inner hub step (from 64.1 wheel seat to 70.1 rotor seat). It's just a guess but if you were doing wheel bearings (yeah, it's probably time if you haven't anyway) a good machine shop could probably take care of both of those for you to get the same thing as RSX-S hub but with USDM ITR axles. Or maybe someone can talk Karcepts into making a variation on their "36mm" swap hubs?

Aren't the oem S2000 rotors the same size for the mugen brakes?

 

Both are 300mm OD but S2K rotor is shallower in height, and same issue as RSX-S with hat ID vs ITR hub OD. (Photo below borrowed from another HT thread)
