was browsing some wheel threads and sites and come across this A-Disk, O-disk and R-disk listed in the specs of some wheels. Like in the link below.

can anyone explain what this is?

Sorry if its a moron question but I simply don't know and figure I wont until i ask.

Thanks

 

I believe it has to do with the curvature of the spokes and how much lip you get with the 3 different types...

O = least curve spokes
A = (standard) more curved spokes
R = most curve (most ideal for BBK's)

Btw, "O", "A", and "R" are the 3 disc type descriptions used by Work wheels....Volk, for instance, uses "High", "mid", and "low".

 

Thanks for the info.

Ordered a set of wheels not too long ago and was getting worried as I didn't get any specs of O/A/R - Disk.

Purchased a set of Advans so I guess they would have a different description then.
Thanks again.

 

How about HP, MD, NR, or SL from some other wheel manufacture like SSR. What are those mean? http://www.ssr-wheels.com/wheels/whe...keepThis=true&

 

+1... thanks in advance.

 

LOL... I really never noticed those. And now that I think of it. What the heck they stand for?

 

Came across those today looking at the new ssr wheel

SL = Super Low Disk: 5/98~5/130, 4/98~4/114.3
NR = Normal Disk: 5/98 5/130, 4/98~4/114.3
MD = Medium Disk: 5/98~5/130
HP = Hyper Disk: 5/98~5/130

Now I couldn't tell you what the translation of those are - just figure that is what they stand for.

 

The answer to your question is located at the bottom of the table on the page you provided. (Or as Vex pointed out below)

I believe the numbers according to disk type you provided describe what bolt patterns are available with what disk types...

For example, the Super Low disk type wheel is available in any bolt pattern from 5/98 to 5/130, and from 4/98 to 4/114.3. (ours: 5/114.3, would fall under 5/98 to 5/130)

And the Hyper Disk type wheel is only available in the bolt patterns 5/98 to 5/130. So with ours being 5/114.3, we (the Z) can choose from any of the 4 disk types.

Those who have cars with only 4 lug bolt patterns, however, can only choose from either the Super Low Disk or the Normal Disk.

 

I am still trying to understand a little bit of this regarding the disk types and their distance from the hub. I'm sure once somebody points it out it will click, but I have a couple of questions. Basically, I'm trying to make sure I have enough clearance for my Stoptech 332mm kit.

So, going by this diagram for my Stoptech kit, I should require more than 38.83mm of clearance for the brake caliper? So, I should even be able to run the SL disk that lists at 43mm?

I greatly appreciate any help or insight into this.

 

Apparently I just got a malware virus, possibly from viewing the .pdf on StopTech's website, so I took down the link. I'll screencap it and post it up, along with the screencap of the SSR fitment guide.

*edit: Okay, I got the images up. Now hopefully somebody can help me figure out what I'm doing.

 

Bump for a legitimate question in this otherwise clogged subforum.

 

I know we're im'ing each other but this will help future people

the 43mm you see on the chart is not caliper clearance, that is the offset of the wheel (distance in mm from the center line of the wheel to the mounting surface). The pad height is what determines caliper clearance - in the SSR world the order goes SP / NR / MD / HP from least caliper clearance, to most caliper clearance

 

Thanks for the reply Adam and clearing up that chart for me.
