I thought I'd post the pictures of the wheels installed. They are:
TSW Jaramas 17x8 40mm both front and back.
The rears have Eibach 15mm spacers with embedded lugs model 90.4.15.001.4. They included new lug nuts but they arent the same pitch as the Mazda OEM ones. Not a big deal but worth noting for completeness.
FRONTS
REARS
I think the outside of the wheels are perfectly flush with the outside of the fenders. There is no rubbing and he took it to 90mph with no vibration. I'd like to get a clearance measurement to the trailing arm.
Hope someone finds this useful someday.
