Rear Wheel Dimensions For Mini Tub

[22655TD]

Anybody have the proper specs/dimensions to order rear wheels for the LPE mini tub set up. I have gotten all sorts of prices on the same wheels but the guys that are cheaper on the wheels ($1,000.00) don't know the specs.
I need to have the proper word usage so they can order.
Offset, backspacing, etc, etc
I plan to use either HRE or Forgeline 19X12 on the rear

They take 4-5 weeks to make and I want to order ASAP.

Thanks

You could shoot GNXguy a PM, I am fairly sure that he did the LPE mini's on his car. He's not running 19's but the backspacing and such would be the same, I believe.
