Thinking about buying them this weekend…

Summit Racing SUM-84-5873 - Summit Racing® 84 Black D Series Wheels - Overview - SummitRacing.com

15x8 5 on 5 , 3.75 BS

there in sale for $40 each

NAY or YAY??

I understand the grinding issue, so if so of you have been happy about them, I might get 1 to test fit

 

i actually ordered some of these for my last jeep jk and it fit without any issue, i eventually switched to the simulated beadlocks that are based off this wheel and it too fit with out issue.

 

I have the same wheels from them but mine have a 4 inch BS and fit fine with no grinding needed.

 

Very Cool

Is there any real advantage over the 3.75" BS or the 4"??

What did you do for center caps??

Did you weigh them out of curiosity??

And forgot to ask in the beginning ...Any pics??

 

the 3.75" sticks out further than the 4" bs, thus putting more load on the axle bearings. it can also cause more leverage to increase the chances of bending your axle "c's". especially so when running larger tires. how much more wear.....im not sure?

i bought some center caps and painted them black.

didnt weigh them but they are heavy for sure.

 

Yeah I know... bringing it back from the dead - but atleast I used the search function

I have a couple questions regarding Summit Racing 84 D Series(Part#SUM-84-7873 and 8 Series(part # SUM-85-7873) wheels :


What does 4.00 backspacing and -12mm offset mean? I understand the backspacing - they are gonna stick out further than stock rim but does the -12mm offset cancel that out and push the wheel back in or does it stick out further than 4" backspace?

Does anyone have pictures of either of these wheels on their jeep?

I am preferring not to lift mine. My old JKU i put 285/70/17 MT's on Cragar wheels that had 4.5" bs and 0 offset. I liked that look.

I've been a member for awhile but I'm still new to this, and after going from JKU to a pickup and now back to a 2013 JK Sahara, I have to learn it all over again.

Any help is appreciated

 

Can someone confirm this math for me. If a wheel says it has 4" back spacing AND -12mm offset... Does this mean the wheel technically has 4.472 inches backspace (or 4.5 inches)?

 

We ran a similar wheel on our JK for a long time. We eventually switched to this wheel in the 17" size when we made our bead locks. We went to the 17" so we had more tires to choose from in the sizes we were interested in running. They have held up to all of our abuse so far. They are definitely heavy probably close to 30lbs each.

 

Got them on mine. Will be doing weld on beadlocks when i get new tires. Mine are 3.5 backspacing i believe. I need a 5th yet may have to grab one on sale and save 10 bucks lol

 

Got similar D-windows on mine from JEGS brand. 15x8 with 3.75" backspacing. The backspacing is from the inside of the rim (therefore lower the number the further it sticks out) and offset is from the outside I believe.
