If I go with a 2000+ caliper i think I will just stay with my evo wheels for now since it sounds like it will work. If I find a good brembo set up I may have to find a twin cam wheel because it should fit the larger brembo rotors? I guess I haven't made up my mind 100% yet. Still in the research and pricing phase.
Dude you need to re-read post #4.

I just spoke with a local HD shop and there is no diameter difference in the rotors. They are both 11 1/2" so with that said the caliper position should be the same. The only difference between the two are the inside diameter of the mounting hole. 99 on down is 2.0" and 2000-06 are 2.2.". if your using your old rim's you should be able to use your old rotor's as well..
A 2000 rotor will not bolt up to 99 down rim's.....
I put 2000 up rims and Rotors on my 98 Fatboy and everything lined up.
Hope this helps......

Edit: I found the link i was reading last night. The write up talked about needing 08 rotors (300MM) vs the older (292MM).
http://www.*****************/forums/...onversion.html
After looking and reading a bit closer the larger 300mm rotors will bolt onto the 2000+ front wheel. So in conclusion if I want to upgrade to the Brembo calipers I need to swap the wheel so I can utilize the larger diameter rotor.
I apologize if I was a bit unclear.

What 98 is talking about is the hole in the center of the rotor not the outside diameter.
The outside diameter is the same on both rotors so your brembo caliper will work with an EVO rotor just fine.

I guess I should have tried to explain a little better in my previous posts what direction my train of thought was going.

I understand the difference between the EVO and twin cam rotors. (Same OD and Different ID). The DIY I linked in my previous post stated you needed the 08 brembo rotors for everything to work. From what I have gathered is ID for both the twin cam and brembo rotors are the same resulting in the requirement for the twin cam wheel to run the brembo rotor.

Owtlaw but Brembos on his FXRP and I think he used stock rotors.

You are correct on not needing 13" rotors. 300mm converts to 11.8". Not sure where I was getting 13 from. It would certainly save money if I can get by with stock rotors.

Actually, I put 2000+ HD calipers on. Stock rotors.

I put an "el cheapo" 2 piston caliper upgrade on mine years ago. It improved stopping considerably. It's been so long ago I don't remember where I got them, but they are still working fine. Did have to cut some of the backing plate off of new pads when I installed them year before last.

I saw that when I looked through your thread. Thanks for verifying though. I guess i wasn't using the right key words when i was using the search bar. Now I just need to find a good caliper.

I purchased a caliper from a 2005 Road King from another forum member yesterday and then I came across a hub ring on ebay to run a 2000+ rotor on a pre '99 wheel. I had a spare rotor laying around from a box of parts that ended up being for a twin cam. Figured it is the same concept as a hub ring for car wheels. I needed a new rotor either way so figured it was worth a shot before I purchased a new rotor.
