Hi Bros,

I'm currently considering the Forgestar F14 for my C2S NB, but would like some advice on the following:

1) the size will be 19x8J front and 19x11J rear. What should be the correct offset?

(I'm going to be re-using my 5-months-old PSS 235/35/19 and 305/30/19)

2) I'm currently running the Porsche original Turbo Style wheels for C2S. Money aside, is it worth swapping to Forgestar F14 for performance (lighter and stronger)?

Thanks.

Factory offset for those rim sizes on a C2S would be 57 up front and 67 in the rear.

Psymon

Thanks.

So ideally I should look for new wheels with the same 57 & 67 offset? If the new wheel's offset is less than 57 & 67, is adding spacers good options?

Cheers.

Spacers decrease your offset. So, for example, if you added 5mm spacers around it would be equivalent to offsets of 52 in front and 62 in back.

There are tire offset calculators you can Google which show before and after so you can see the impact of different size wheels and tires.

Hope that helps.

Psymon

Got it. Thanks.

I may be mistaken but I think the Turbo wheels are the only forged OEM wheels so you may not gain much in either strength or weight reduction.

Psymon

Thanks. That's what I heard as well. So I guess this change will be for cosmetics only then. I'll have to look into the offset issue further.... I have a C2S and the wheels came off a C4S.... waiting for owner to confirm the exact offset.

I spec'd mine with the below specs. I wanted flush fitment and they're spot on. No rubbing, no spacers. Optimized footprint.

19x8.5 +46
19x11 +52

Thanks, Jesse.

They look perfect! Is it a C2 or C2S and was it lowered? And are you running 295 or 305 in the rear?
