PCD conversion 5x120 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Maybe someone can help. I have a set of BMW wheels i want to fit to my BRZ. looking for a conversion kit that will work without removing my studs.

Wheel specs are as follows (5x120) -
Front 18x8 et 45 72.6 hub bore with 225/40/18
Rear 18x9.5 et 45 72.6 hub bore with 245/35/18

I can only find one kit that works with the studs but it will only covert to 5*114.3.

For this to work i think the maximum thickness can be 15mm. This will give the following resulting offset
Front 18x8 et 30 with 225/40/18
Rear 18x9.5 et 30 with 245/35/18

Any ideas on finding the conversion kit and if the final setup will work would be appreciated.

Thanks

Imho 5x114 wheels are way more common, and given pcd convertors being narrow niche products as they are, i doubt there being much of an business case to make 5x100>5x120 one. Best bet if you absolutely must fit those wheels imho is making custom PCD changers. But by then question rises if there are any savings on not buying normal direct fit wheels set in first place.
P.S.
I wouldn't do staggered tire setup on twins to not ruin handling. And even if forced induction is installed, it's worth up tire width in square setup instead of just rear for same keeping handling balance purpose.
