rim size on gc8
whats the offset and stud pattern (5x100 or 5 x114.3) for a 99 model wrx?
does anyone know if 18x7.5, 5x100 offset +40 rims will fit on my99? and will 225/35/18 tyres fit on these rims? thanks guys |

5 x 100 is the correct stud pattern, +40 offset should fit, although it might stick out a fair bit, creating clearance problems with the guard when you're turning, especially if your car is lowered.
From memory, stock 16x7 rims have a +53 offset, most aftermarket 17x7 rims for a GC8 are +48 offset. Given that, I have a hunch +40 might stick out quite a bit! Maybe it's time for a 22B widebody kit conversion :P 225/35-18 is the correct size for a 18x7.5 wheel, but make sure the load rating on the tyre is at least 87V as required for a GC8 or you might risk insurance dramas. |

What about tyre size for 17" rims?
Also, where can I find Advan Kreuzer X or Advan Kreuzer V 17x7.5 rims?

17x7s on GC8s ideally should use 215/40-17 tyres, but tyres in that size with load rating 87V or higher are quite rare.
fmx rider I think you are quite right. |

The 45's adjust speed readings by about 3% which means if your speedo says 60km/h you're actually doing ~62km/h

Yeah speed readings don't differ much going from 215/40 to a 215/45. However, there are noticeable trade-offs in terms of handling and acceleration. I had 215/40 tyres, and subsequently went to 215/45 tyres. I found more sidewall flex on the 45 profile tyres and a slight drop in acceleration, probably due to a larger diameter, increased tyre weight, or both. That said however, it probably is neglible in most applications.
To the best of my knowledge, tyres in 215/40-17 that do meet the load requirements of a GC8 include Falken GRB FK451 and Continental ContiSportContact (sic?). |

isnt the smaller the offset, the more they stick out? Ie +40 would fit quite easily, whereas -12 is a "belongs on a widebody celsior" offset?

Other way round Josh.
I think anyways! The newer STis run a big offset (around 40 I think) so the rim clears the Brembos. My GTR however ran an offset of something like 20-22. |
