Opinion needed on wheels fitment and performance. Please read.
 

First let get to know a little about my car. It's a 1987 normal 911 converted to a turbo wide body slantnose. The engine is still none-turbo. Although it's running very well, but not too fast. The car is for street only, not race. Now, if the car is yours, please tell me which choice would you pick and please briefly explain why:

All factors consider such as power, performance, steering wheel effort. of course wheels/tires cost effective are also considered. If not, I would custom a brand new set of super deep disk Kenesis or Fikse :eek:

1- 17x8.5 front and 17x10.5 rear (kodiak without adapters)
2- 17x9 front and 17x11 rear (kodiak without adapters)
3- 18x8.5 front and 18x10.5 rear (kodiak without adapters)
4- 18x9 front and 18x11 rear (kodiak without adapters)

5- 18x8 front and 18x10 rear (modern wheel with flat lips, will need 2" and 3" adapters. For 1/2 price compare to Kodiak)
6- 18x9 front and 18x11 rear (modern wheel with flat lips, will need 1.5" and 2.5" adapters. For 1/2 price compare to Kodiak)

Thanks in advance.

If it were mine?

9.5 & 11.5 x18 with 255s and 315s.

1 or 2

since the car doesn't have that much power (stock), do you think so big of wheels and tires will slower the car down?

1- 17x8.5 front and 17x10.5 rear
