What size spacers do I need for wheels to sit flush?

[Uzair]

Hi,

I have a set of BBS wheels I'd like to use on another Supra I've bought (and still waiting for Ageas to settle my stolen Supra!).

The fitment on the wheels are:

Front: 18x8J ET39

Rear: 18x9J ET42

Currently they sit quite inside the arches but I'd like them to sit flush in line with the arches, and I'm not sure what size spacers I would need. 

Could you please assist me with this and also what size Center Bore I will need? Will it be 74.1?

Best regards,

Uzair

What size tyres do you want to run ? 

Do you have a picture of the sort of fitment you want ? It might be worth trying to borrow some spacers and have play.  I would start with 20mm but you will probably get away with 25mm spacers.

I reckon 30mm rear and 25mm front and as matt says above after that its tyres but given the width of the wheels you wont be able to go with functional massive tyres. A 265 rear and a 235 front would probably be fine. Lovely wheels.

Thank you so much.

I came across a thread with another member selling their wheels and I loved the wheels and how they sit. I'd love mine to be the same or just as close, though I'm aware the tyres and the rim size make all the difference. 

I've attached a couple of photos of his beautiful Supra for reference. 

The current tyres I have on are: 

Front: 235 40 18

Rear: 265 35 18

His wheels were these specs -

19 x 9.5 +22 and 19 x 10.5 +37

Yours would need a 35mm front spacer and a 25mm rear spacer to achieve the same level of flushness

Please bare in mind you dont know what arch modifications he had ( if any )

Got it!

Thanks a ton!
