Forgestar --- Ball or Conical Lug Bolts ? Tested factory ball and they seem right
Gents -
I read that forgestar changed their machining of wheels so that ball seat lug bolts could be used.
I tested one of my stock lug bolts with the wheels off the car and they seem to fit perfect.
Any advice ? How do I figure out what is needed ? I did email forgestar will see what they say.
Thanks!

Conical it is
For the forum archives - Got an email back from forgestar and the wheels require conical bolts.
With stock Ball I got about 4.5 turns. With conical I got close to 7.
I went with 14x1.5 27mm

This thread strikes a chord with me as Forgestar originally sent me front wheels machined for cone seat lugs, and rear wheels machined for ball seat. This was after waiting 5 months for my order btw. After going several rounds with them saying it is not possible, I sent the rear wheels back. They confirmed they screwed up and offered me $100 discount to keep there mistake, or wait in line for the next set of rear wheels to come in. My choice was to wait.
So, my first thought is run! Find a company with better quality control.
If you already purchased them, inspect them carefully before mounting. As for the bolts, the bolt holes are narrow so conventional wheel locks might not work, ymmv. I went with spline drive conical seat lug bolts that were 25-27mm. 25mm would be the minimum length you could use.

Based on the stories in this thread, it sounds like the OP should manually check the shape of each wheel's bolt seat (finger or some playdough/clay on a stick should work). To get proper bolt length, measure the depth of the wheel hole after the ball/cone ends to the rear face of the wheel, then add (at a minimum) the threaded depth of the holes in the hub + thickness of any spacers you may be using. Don't go too long either, as you can run into interference problems on the rear side of the hub.
You don't want to run a cone bolt in a ball seat or vice versa.

I am pretty sure they would tell you if you ask (when you buy) what the bolt type is.

And I'm pretty sure they'll give you an answer, but based on the stories in this thread, I would check myself when I received the wheels (if they were my wheels). It's not difficult to do and you would have certainty.

When you guys are talking 14.5 x 27mm you do mean 27mm length from the bottom of the cone to the end of the threads right? Not 27mm total inckluding the socket head?
Thanks
Thanks
