Question on wider 20" wheels (Ferrada FR8)

Shot Ferrada an email asking if they had any FR8 models available, what the center bore was and if they had a recommended or tested fitting for the i8.

Anyhow, here is what they have:

Quote:
FR8 fitment is 20X9 et 35 & 20x10 et40 / weight for 20X9 is 24 lbs, 20x10 is 27 lbs
Stock i8 (Style 470 anyhow) is:
Front: 7.5X20 et40
Rear: 8.5X20 et50


So

Front
7.5" ET40 to 9" ET35
14mm less INNER clearance
23mm extended OUTER clearance

Rear 8.5" ET50 to 10" ET40:
9mm Less INNER clearance
29mm extended OUTER clearance


Hmm, I see people taking about crazy sizes here but in the real world I live in, with pot holes and speed ramps, I have to ensure they don't rub when the suspension does its job. 29mm on the rear is way out to the arch (as is 23mm on front). 14mm on the front inside is real close to the brakes too.

Anyone have similar sizes (on stock suspension) and can comment or ideally show a photo?


PS: Any other reasonably priced options that look similar but weigh less? These actually weigh more than stock.
PPS: They sent an update:

Quote:
Center Bore 66.56
No rubbing issues and we have tested those wheels on that car before.
