Fitting 17" Challengers Question

[Pepper]

Thanks for the replies guys. The deal breaker on the alloys was that they had new tyres (I'm due some new tyres on my car). They're 205/50/17 so we've concluded that they're too big. I'm continuing to look for challengers/nimrods or cyclones maybe.....anything better than what I have now lol.

So with spacers, I'll need to get some longer wheel nuts too? Would they be tapered or flat? I've got harriers on the car atm so I've got tapered ones.

Cheers,
Chris
