Wheel Question

Here are the specs for a BBS wheel that came off of a 458. The sizes are correct for 599 but the off sets are different.
Can someone please tell me if these will work on a 599?

Front: 44, GTO: 38, Challenge Wheel: 43.5
Rear: 56, GTO: 63, Challenge Wheel: 63.8

The front looks like it will work, the rear I'm not so sure about.

Are these too far off?

George- Those will work fine. The rears are 1/4" (~6 mm) narrower than OEM but will not make much difference with same size tires if you do not mind. As a bonus, you get 3/4" wider front wheels. May slightly increase understeer, but easily countered with throttle on a 599.

 

Thank you Taz! What would be the best tire size for this set up on the 599, OEM sizes for Challenge?

 

George- Affirmative, but you could still go one size larger on the rear if you want MPS4S tires without a problem.

 

George, take my calculator

i took the last wheel "458" with the sizes you wrote.

I had 22 mm and 25 mm spacers with 255 and 315 tires on my GTB before i mounted the GTO rims

At the B+C line 8 you see the spacers i had on the car.
At the B+C line 12 you see the measurement from hub to rim outside.

If you mount the 458 you can go wit 12mm and 20mm spacers (line 11) to get the same result as with Monolitic and 22/25mm spacers like on the photo
