Aftermarket Rotors

Recommended Posts

1tondriver

Who is running them and which ones? Are you noticing a considerable difference over OEM? 
The reason for the question is that I have an opportunity to pick some up for about half price. I am not sure I will see the benefit however just doing the occasional track day and some spirited street riding. If I were to make a change now would be the time to do it since wheels are stripped. TIA

Depending on the rotors you can save on unsprung weight and/or get improved heat dissipation and possibly better braking. 

Have you got a link to the ones you're looking at?

 EBC Vee’s. They are pricey even at half off. I understand the weight savings and heat dissipation, good stuff no matter what. I am really wondering with my type of riding beside the cool factor am I truly going to notice a decent difference? Thanks @DewMan!

Disclaimer: I do not have nor have I ever used aftermarket rotors. 
My understanding is that unless you're pushing the bike to it's limits I don't think you'll notice a difference. 

I'm sure others can chime in with first hand experience as to how much, if any, difference they make to daily driving.

Maybe this will help me. You are in my position and can get 50% off the rotors and the wheels are stripped down anyway, do you do it? Or, would I once again just be getting a “good deal” but not really needed and won’t benefit much if anything by doing it? I usually would just do it because but I have a resolution to be more responsible which is turning out to be no fun 😟

I don’t know why I even ask the worst support group when it comes to spending money on parts. Lol

I'm sure whatever rotating weight and heat dissipation claims made are totally plausible, but I seriously doubt anyone other than the most perceptive/sensitive of highly experienced rider may feel any difference. 

Our wave rotors are what all the cool kids were paying EBC big bucks for years ago when nobody was giving them out as stock equipment. 

Performance advantages? Maybe.

Longevity? Versus stock Japanese parts?...that'd be a hard sell.

You want it and can afford them? Nothing to lose there!

Thanks for being a voice of reason. I can afford them but I am not going to get them “just because” in 2020 (I have a pact). I think I am going to take a pass unless anyone else has some good reason for me to go for it.

I just put a set of EBC 320mm rotors on my FJ-09( granted I also had to use some caliper spacers, OEM is like 298mm)... them EBC rotors are THICK!!! Like 50% more than stock...

Were your OEM rotors toast or did you want to upgrade? Notice much difference in braking?

I was waiting for some sort of “no quitting buying aftermarket parts” comment so I must say I am shocked 😳

Big difference in braking- bigger rotors equal more leverage applied...

Is there performance benefit with upgrading to floating rotors?

Floating rotors are simply better. They don't warp under heat expansion and are less likely to crack ( not common these days). EBC floaters big advantage is usually that they are much lighter.

Less rotating mass means better braking ( less moment of inertia).  I really like EBC discs, and have for a VERY long time. Disc material has a big bearing on feel, power , wet performance and longevity. In the 80's they tried all sorts of grooving and drilling to improve wet performance and found that disc and pad material had much more effect than anything else.

Are you running these on your 07?

The EBC rotors are not much lighter than OEM... look at the thickness of the EBC vs OEM... EBC is on bottom, OEM is on top...

🤔 Wonder what they each weigh?

Wouldn't be a far comparison... the EBC is 320mm and OEM is 298mm on my FJ-09... I had to use spacers under the caliper to run the bigger rotors... 

This mod will not work with the OEM FZ-07 forks as the caliper is mounted different...

Just wanted to show the difference in thickness...

My 07 still has the stock rotors as it hasn't done enough km to warrant a change. I will change to ENC's if they are available , when I wear these out.

I have changed the rotors on almost every bike I have raced ( where possible) and my project bikes. Almost all Changes were to EBC . One was to a custom made pair on my VTR 250 proddy, which were VERY much lighter by request because EBC were not available.

Very unfair comaprison above as thicker rotors and most importantly, bigger diameter. You are adding nonlinear extra amounts to the outer diameter. Even at the same swept width surface and thickness, they will be heavier than stock ( swept width and disc thickness).

Thicker rotor is USUALLY more stable shape under extreme braking...usually... Bigger heat sink for the same heat generation.

Did those thick discs fit in the stock calipers? They don't look like correct model fit. I reckon you would be struggling to get them in with the pads and stock calipers. I did have that problem with EBC's I put on an ER6N though. Had to remove pad material. On a racer so easy to keep an eye on them.

Ooo yea they fit with stock pads or a few have used HH type of pads... FJ-09...

If you're going to the track I would look at Braketech Axis.  The force isn't transferred into the buttons like a typical floating rotor.  The hub on the axis transfers the force from the disc into the hub instead and the buttons aren't deformed from force.  Brembo T Drives work similar but not exactly, I prefer the design of the BrakeTech Axis.

A lot of aftermarket rotors are thicker and not meant specifically for street use or to be plug and play.  Removing pad material isn't uncommon in aftermarket, thicker rotors.

Once again lots of good information here 👍

If upgrading is it necessary to upgrade the rear as well or do people run different pads and rotors up front only?
