    Rota RB/RB-R, 4x114.3, 17", Z-Offset Wheels

    in Group Buys

    I wrote this calculator for finding front and back spacing...

     

    http://www.autolounge.net/calculators/tirespacing.html

     

    Here is the approx BS and FS for the 3 wheels:

     

    8.5" +04 /---/ 4.90"BS /---/ 4.59"FS

    9.0" -13 /---/ 4.48"BS /---/ 5.51"FS

    9.5" -19 /---/ 4.50"BS /---/ 5.99"FS

     

    So as you can see, the 8.5" sticks out about 1.4" less than a 9.5" and the 9" a little under 1" more than the 8.5". Hope that helps.

    Okay, so I was able to contact Kim without any issue. If you are someone who has an issue currently and for whatever reason CANNOT contact Kim, please PM me your email address, name, and issue and I will talk to Kim about it and see if I can get it cleared up. I don't really have much time at all anymore because I am finished up my mechanical engineering degree, but I am still committed to keeping this group buy running.

    NOTSUREWHATOUTPUT, I looked on google and the nearest Discount Tire is way over 50 miles away from where I am.

     

    Anybody have any recommendations as to a good reputable company to trust with my wheels and tires needs?

     

    I apologize if I am hijacking this thread. It seems on topic.

     

    I would tell them the specification of the tire and be frank with them that you don't want your wheels to be screwed up, see what they say. When I was having the prototypes fitted with used tires all the shops seemed to be struggling pretty hard, if they were new wheels I would be afraid of them getting scuffed up. I didn't go to any specialist though and with all the low profile tires out now, I would think that they have gotten better at mounting these types of tires.

    Those are RB-R's for sure. A lot of people like 9.5" all around because they can rotate the tires. Also, more section width does not always necessarily mean more stick.

     

    I am so glad this is still going and people are enjoying these wheels. Ironically mine are sitting in a box as I have lost momentum on my own Z. Haha. =]

    Has anyone been in contact with Kim?

     

    I sent payment for one wheel via money order on the 5th of this month prior to contacting Kim and haven't heard anything.

    I've sent e-mails every other day to be in contact, but there hasn't been any reply. Can someone get into contact with Kim?

     

    I am confused as to why you would send payment for one wheel without contacting him... You should call him, his phone number should be on rotawheel.com.

    Quick question? Do I have to special order these wheels from Kimcosmic@juno.com because i cant seem to find them anywhere on ebay, wheel shops, etc. Would they still be avaliable or was it just a one time thing?

     

    This is answered 3 post before. To order the wheels email Kim at that address. I doubt you will find these or want to buy them off Ebay or wheel shops - it would just cost more.

    Sorry, after reading this whole post, has anything like this been done, as far as breaking down what works with and without flares, tire sizes, lowering springs, and offsets?

     

    I may have missed it as well, its quite a lot of reading LOL...

     

    Thanks

     

    Jay

     

    Well the group buy has always required flares, coilovers have never been required, nor lowering springs. Kind of makes the four different categories pointless. The offsets are:

     

    17x9" Front -13mm

    17x9.5" Rear -19mm

     

    The wheels should fit stock suspension. I recommend 245/40/17 or 255/40/17 front and 275/40/17 rear. You will need to flare. You will need to trim some of the lower valance on the front of the car as well if you are not running an air dam. Even then some air dams may interfere, others do not. Air dams that drop straight down at the front of the wheel well typically do not need to be trimmed. Hope that helps.

    Hey guys! Sorry I didn't really do the "repair" of the helical section justice (JMortensen gave me a nice detailed explanation). I know there are inaccuracies in the website and such, I just haven't had time to update it or work on it. I am in my last year of college at UC Davis for Mechanical Engineering and am quite busy with that and enjoying my last years of college. Once I am out though I am sure I will get right back to it.

     

    I also made zcarpartsindex.com... if you guys would like to contribute to that I would REALLY appreciate it. I envisioned a wiki dedicated basically to helping Z car restorers and hybridizers but it never really took off. Almost all the content is inputted by me. Here is some differential information for JM. =]

    Also the raw data in the 0-60 times took an extremely long amount of time to compile. There is some good data there for doing statistical calculations and trends etc etc. I just never actually processed it beyond averaging it and such.

    Hey guyz,just wanted to give an update about last year in Nov of 2008 I placed an order for my RB-R's from rushkits.com and I thought I got an O.K price,but anyways I recommended the company.To make a story short I never recieved my set of wheels and the company was no help trying to either return my money or get the wheels for me,it's been about 10 months so I had to get the my bank involved. SO DON'T ORDER FROM RUSHKITS.COM(there based out of Glendale C.A) UNLESS YOUR READY FOR NO CUSTUMER SERVICE AND WANT TO GIVE YOUR MONEY AWAY!

     

    Sorry to hear about your missfotune with rushkits.com... this thread though pertains purely to a group buy through the North American Representative for Rota so it doesn't really apply. I highly advise you just deal straight through him. There is almost literally no point in dealing with anyone else as you are just going to pay more or possibly in your case get ripped off. Good luck resolving your issue.

    Does anyone knows if these wheels are still available?

    Emailed Rota(kimcosmic@juno.com) a few days ago

    but haven`t gotten any reply yet..........:(

     

    And they look so great:flamedevi

     

    Should be, be patient he should get back to you!

     

    does anyone have the rota rb r 17 x 9 - 13 all around on a s30 without zg flares and if so if you could please post a pic

     

    I don't have a pic off hand, but I promise you they stick out. About an inch to and inch and a half upfront IIRC.

    This is entirely impossible IIRC on all versions of the RB or RB-R both prototype and production that I saw/specified/measured. It is true that the RB's had a pad maybe 2" thick or something similar, but the holes for the lug nuts were recessed into the pad so that the actual meat between the mounting surface and the bottom of the taper was probably around 5/16". You would need to grind off 13mm of material since it is a -19 offset. You would end up having four approximately 30mm diameter thru holes in your wheel.

     

    Personally I wouldn't recommend shaving the back off almost any wheel I have seen since they typically all have around 5/16" of material between the taper and the mounting face. That is from my own experience though, I am sure in the past there have been wheels with much more material after the taper.

     

    Sorry for the bad news, you might try starting a Supra group buy if you really have your heart set on these wheels, otherwise go custom or get your hubs redrilled. Lastly you can always flare the car... that is what everyone here is doing since these wheels won't fit our cars either unless we flare them...

    It is funny you mention that these would sell like hotcakes on a 240sx forum. I tried diligently to get interest from 240sx owners... I was told that they were cheap and would break since they are Rotas. Since then I do not deal with 240sx owners.

     

    thanks man.

     

    wow, of the several 240 forums i frequent everyone is buying p45r like there is no tomoro...sorry to hear about the bad experience. but are you able to help me get a set of these despite that fact that i want to put them on a 240?:D

     

    also, i want to apologize for badgering and asking questions in your guys's group buy thread, i just can't find any info on getting these wheels anywhere else.

     

     

    im sorry, but i dont quite get what you meant by that?

     

    thank you,

    Dorian.

     

    In my haste I quickly replied and didn't end up saying what I meant. Sloppy mistake. In any case when I said "I do not deal with 240sx owners", I didn't mean you in specific. I meant as a whole I do not advertise to them because they typically just bash the perceived quality of the wheels. I did not mean to imply in any way shape or form that I will not work with open minded 240sx'ers. I just tend to stay away form their forums as a whole. Sorry if I came off rude, I would like to think myself not "that type of person".

     

    When I said I don't think you will have an option, what I meant was:

     

    I don't think you will have a problem.

     

    As in, it should clear your brakes just fine. A bit of advice, if you are looking to stick wide tires on your car you will be wasting potential going this route because 240sx's have more available backspacing that S30's. That is to say you could add probably an inch to an inch and a half of positive offset to these wheels and fit them fine. Ideally these would probably be 17x9.5 +5 for you or something similar. Then to make up for the inch you slid in you would instead use a 10.5... so spec something around a 17x10.5 -6 or so. Once you find out your BS, I made this handy calculator... enjoy!

     

    http://autolounge.net/calculators/tirespacing.html

     

    Find out the size you ideally want (be meticulous), get your fellow 240sx'ers together and go in on a buy. That is what I advise. The contact for the representative is here:

     

    kimcosmic@juno.com

     

    If you just want me to do it all for you, this is possible, if you pay me (haha) but you will still need multiple people. You basically have to become the representative for Rota for about a year and a half. I have already done that much though, so maybe this time around it would be shorter, but I doubt it. Good luck!

    thanks a bunch for the reply.

     

    as far as the interest of s13 owners, i dont know of any other wheels that are available in 4x114 this wide, with this low of offset besides some ssr, volk and works and a few others that cost close to the amount for this set, per wheel. There are several choices for wheels that have good offset for stock guards, but are way too high offset for any of us running wider fenders. positive offset is kryptonite in the s13 world, trust me.

     

    any s13 running wide fenders and still running 4lug hubs is in the same boat you guys are. pretty sure these things would sell like hotcakes on a 240 forum. i would love to see rota make the p45r available in these offsets in 4x114 as well, i would pick up a set of those too.

     

    as far as getting my hands on these wheels, i tried emailing Kim but haven't gotten a response. is there any better way to get in touch with him?

     

    Thanks,

    Dorian.

     

    Brake clearance is exceptional. I will be going to my college house this weekend and will measure the wheels in detail, maybe even cad them out. In any case, I don't think you will have an option.
