Best offset for BBK Clearence.

[jules325i]

cant wrap my head around the whole offset thing,
In limbo about to order wheels for my track car, I'm planing on fitting a Front and rear 310mm BBK From IE, My options are as followed.
Im happy to run spacers As i have 90mm wheel studs.
Rota Grids-

• 16x8 et10
• 16x8 et0
• 16x8 et20

or is there another 16" wheel out there that is better suited and able to run the BBK front and rear.

the lower the offset number, the better the clearance. so out of the 3 you posted the et 0 wheels will clear the best, but also stick out further than all the others on the outside.

Thankyou, very helpful.

Offset is NOT the only deciding factor in brake clearance. Wheel design is. For example, one set of 16x8 ET20 wheels I had needed a 20mm spacer to clear my UUC brakes. Another set of 16x8 ET20 wheels I used cleared the brakes and left another inch or so between the caliper and spokes. Rota Grid shouldn't be too bad for clearance. If it were me I'd order the ET20 that way you can add spacers IF you need them. ET0 isn't exactly an ideal size for a track car or meaty tire fitment.

Ok that sounds even better, I will be running 225/45/16
I wonder if UUC Kit sticks out as far as the the willwoods, is that kit anygood?

Im really hoping that 16x8 et20 rota grid classic will clear Willwoods BBK Front and rear, even if i have to run a 20mm spacer.

Did they clear the bbk? I am in the same situation as you but I have not ordered the wheels yet. Please let me know thanks.
