I was looking for wheel company for about 3 months. I remember I found some in US but they didnt reply my email.
Finally I found these guys.
Yeah, Billets 35.
WHEEL DIAMETER = 15"
WHEEL WIDTH = 2 x 7" 2 x 8"
C'SINK ANGLE = 60 degrees
BOLT CIRCLE DIA = 4x98mm
DIAMETER OF STUD = 12mm
LENGTH OF STUD FROM FACE OF HUB = 35 - 50 mm (variable)
BACKSPACE TO INNER FLANGE = 80-90mm (80mm preferred)
HUB PAD DIAMETER = 150mm - 170mm acceptable (150 preferred)
CENTER HUB DIAMETER = 58mm or greater (58mm is hub-centric fit)
FORWARD PROTRUSION OF BRAKE CALIPER = 7mm
DISTANCE FROM HUB CENTER TO THE BEGINNING OF CALIPER = 66mm
DISTANCE FROM HUB CENTER TO THE END OF CALIPER = 134mm
These are all sizes I have provided
My main aim was to fit wheels without any spacers and I did it. Perfect fit.
Ive used lug bolts that came with the wheels. Not sure about the difference to lug studs with bolts?
One issue I have is that the front wheels will not fully rotate as they touch the inner arch.
BTW: Image Wheels is a nasty company, they dont care much about individual customers as they have contracts with racing teams. The sales guy stated to me 4-5 week production and delivery time. After week 5 I was sending email asking where are my wheels and I was getting same answer - they will be ready next week. I got my wheels only on week 10, so overall more than a month of unplanned waiting.
So keep in mind this as well.
Leo.
