Looking to install my set soon. Need to figure out lug nuts or wheel studs.

Are the lug nuts in these photos Gorilla Extended lug nuts O/P is using?

Also, is the lug nuts with more threads engaged on the APR wheel stud/Bolt?

I think O/P is using Gorilla extended lug nuts with OEM studs, is that enough?


do you have this same offset? I currently have the regular length ARP studs on the front and the oem style on the back (or whatever length came pre-installed on the hubs when I bought them from doorman)

My thoughts are that I would probably be OK with the regular length ARP studs all around with these +55.

OE style regular length Vs ARP regular length:


Seems like there might be 1 or 2 more threads on the ARP.

Here is my set Bronze set ordered this year. It actually looks more on darker brown size during darker lighting condition as the photo of the inside of the wheel shows.

The more bronze/gold photo is taken indoors with bright fluorescent overhead lights.

 

What size and offset did you get? If u have bbk, what bbk do u run?

 

17x10 +55 my rough measure shows that it might be some where between +50-52. Need better tools.

I haven't mount yet. Plan on using them for Racing Brakes BBK

 

So you are the second person to say that their on the box offset doesn't match the real world offset. Is this common for most wheel manufacturers or is this more just a Forgestar issue.

 

I've never had a wheel "match" the labeled offset, when measured from the center plane defined by the maximum point from inner to outer rim edge. But I've never had two wheels of the same make and model not match the measured offset within <1mm. I think it's just a matter of how the manufacturer measures offset, everyone is probably using their own datum. Forgestar may very well be using a more accurate real centerline--the tire may actually sit closer to the edge on one side than the other, so we may not be able to really measure the way they define it. Relative measurements should be accurate if they are machining accurately.

What would be pretty useful information is if someone orders a +50 or +60, then we can measure that out the same way I've measure mine, and we can see how repeatable the measurements are.

edit:// Didn't know about the Racing Brake kit. I did find an fitment template here: http://www.racingbrake.com/v/downloads/2146fitment.pdf

I've been pretty busy lately, but I'll try to repeat my measurements to determine minimum offset for this kit as well sometime soon.

 

I have a set of 17 X 10 ET50's. Just measured offset using granite surface table and digital height gauge. Using the inside surface of the outer flanges as the width reference, I measured 50.8 mm offset. The flanges are not perfectly vertical so I'm guessing my measurement is +/-0.5mm

Wheels easily clear Urge Design AP Racing front brake kit. I'm running Hoosier 245 A7's which are extremely wide 245's (closer to most 265's). Rear fender lips are trimmed, fronts are rolled and slightly pulled.

BTW: The box labels show Offset: 25mm, S.O.: 25mm. I ordered 50mm offset. Anyone know what S.O. means? Perhaps S.O. is the "standard offset" of the wheel/hub face for the casting and the "Offset" is how much material is removed to get final offset? Total guess based on numbers given and math adding up.

 

Thanks for the pics as that is the exact same tire setup I plan to run. I am hoping to get a set ordered this month, and I am still leaning towards the +55s for OEM fenders, Stoptech STR40s, and -3 camber.

 

For reference, my 17 X 10 ET50's weigh 19.0 lbs using a Park digital bike scale.

 

still wondering if extended studs are needed? I rather be safe than sorry. Then again sounds like wheel stud install is a bit of pain also involving bearings.
