sorry, been out on site inspections all day and finally got the computer going. anyway, just thought i would post a teaser as to what ive done. ive only spent about 10mins so its pretty simple for now. i plan to take some more measurements and take a peak at what the H&R spacers look like in their entirety tomorrow and finish it up. this is a 20mm spacer.

Count me in for a pair of 15mm spacers if you can do 15... if not, I'll take 20mm

Kool. Its really a simple design. I believe they give more measurements on certain websites.. the center hole is 61.1mm i believe, and the obvious 5X114.1 lug pattern. Does anyone know the OEM stud length??
I am going to (hopefully I remember) check some parts stores while I'm home this weekend to check price & availability on +20mm studs.

Very nice. Thanks
so we'll need that exact same spec., just with a 62mm length.

5x114.3

And I think the hub center is 66.1.

sunstream453

anybody have calipers to check that for sure? maybe someone has a disc off the car and can just measure the opening? its been hard to measure that section, i think i might just take a circumference reading and use that to find radius, but a good measurement would be nice.

'02_EMILBUS

iTrader: (3)

5X114.3 yes, thats correct sorry.
And center bore, I found a reference of 66.2.

sunstream453

is 66.2 the actual for the spacer/rotor or for the hub?

sunstream453

ok, here it is with the 66.2 bore. if the 66.2 is the actual spacer bore then i will take the center back in a little, as of now its a little larger to allow for clearance. check http://www.onlinemetals.com/ for the aluminum. thats where i got that price from

Are you going to machine these on manual equipment?

sunstream453

machining these on manual equipment would take forever. youd need to use a lathe and mill. on a CNC mill you can do a complete unit without using a lathe and it would take about 1/10th the mill time. i hope for the sake of anyone that makes this that its not manual machinery

Whitebread

iTrader: (2)

Thats why I asked . I considered making 2 sets of spacers myself. But using manual equipment would require the use of a rotary table or specialty equipment designed to clamp round stock in a mill (I forget the name right now). I'll be learning how to use my schools NC and how to write G code this fall. .

sunstream453

02, im ready to send you the part file. just let me know your email. i think i want to start with just you for now so that you can make a test piece to make sure everything is in spec. I kind of doubt that the hub will be perfect the first time, so i want a piece made so we can have it perfect before i send anyone else the file.

sunstream453

im just wondering, does anybody car for the extension for the wheel mounting? im not really sure if I should include that or just have it be a flat surface. as for myself i dont care because my wheels arent hubcentric and dont have hubcentric rings, plus i dont really believe in the whole wheels needing to be hubcentric. the spacers will most certainly be hubcentric, but i need to decide if i need to extend the hub too. any input is welcome

'02_EMILBUS

iTrader: (3)

I would like it to be there. It's a little extra insurance and I have stock wheels so It would most likely benefit me rather than hurt. My opinion...

sunstream453

ok, well i think i figured out what the deal is with the hubcentric extension. ill draw it up here in a minute and then email it.

sunstream453

i emailed the part file to 02 emilbus the other day, hopefully he is working on getting it set up. if nothing happens by the end of this week, either contact or a prototype from him then maybe someone else will have to try, but for now i think hes got it

'02_EMILBUS

Oh I've got it! I was away all weekend and been busy yesterday and today w/ work so I haven't opened the file yet. It is in a 2007 program, correct?
But I am going to get somewhere with it this week. I hope to Possibly cut some out of a cheaper material this week (for test fitting when I go home this weekend). So then if any modifications to the drawing need to be made, I won't be wasting $$aluminum$$.

sunstream453

good idea cutting it from something cheap first, you also will get the process down first before you start cutting away on the good stuff. its from an 07 program not an 08 so thats not gonna be a problem. i think i remembered to mark it as a 6" diameter, but if not it shouldnt matter as long as youre using 6" stock. if its 6.5 then let me know, 5 min fix and ill send the file right back

'02_EMILBUS

iTrader: (3)

It is at a 6" diameter.. which shouldnt be a problem. I have SolidWorks here as well so any changes that need made I can edit. Getting the process down won't be a problem either since it'll be all CNC
Did you take plenty of measurements on the rear rotors; i'm talking 'bout the "locating ring" that will slide into the spacer?? Is the protruding distance measured, so that it will not interfere w/ the spacer butting up against it?
And I also believe that you don't have the stock 17's?? So I may have to check those measurements for a taper or any interference???

thanks again!

sunstream453

yea, i took a good number of measurements, so in theory there shouldnt be any interference. what i did was what it looked to me that the H&R's did, i dont think there is any taper needed since the OD of the protrusion is the same as the ID of the hubcentric peice, IE it should be the same as the hub

looks like yal are getting close!
congrats and HOORAY!!!

been watching this thread move along.

I'd definitely support this any way possible.

Really nice thread and interesting... But can you post some pics with all the measurments...

'02_EMILBUS

iTrader: (3)

I don't have any material here at work large enough for a sample piece. I'm gonna look around when I'm home this weekend and try to find something.
Also after pricing round aluminum stock, I really need to price the extended studs and do a cost analysis.. but I'm sure this will still be worth it. Sorry for the delays, but please be patient and stick w/ me.

sunstream453

any updates?

'02_EMILBUS

iTrader: (3)

Been very busy since last update w/ little to no progress. I have one week of work left here and no sample steel or access to scrap w/ a diameter large enough for a sample. I have looked around for different prices on the aluminum and I'm hoping to be able to give the file final file to a machinist/instructor at school and have them mill it out on a CNC there. So I'd say a temporary delay on this... but surely not giving up. Just a lot goin on guys and I'll keep updated!
My efforts are to make this with the best resources and at the lowest cost for All.

AND... where did you get those stud specs.. you say NAPA catalog.. was that online or your own research?? Just trying to verify everything and compare it with the SolidWorks file.. which I did some editing to.

so... whats up with this thread.... it would be really interesting to know more...
