      Running 325s on the front of a 77 trans am

      Gonna flare the front fenders. I'm using a stock subframe and speedtech street fighter kit with the tubular a-arms and coil overs. The extra width on the wheels went outward, so my scrub radius is probably "too much". This is mainly a street and cruising car but is set up with a cage for stiffness. I noticed these cars move too much and it drove me crazy before. Hopefully the cage doesn't drive me more insane. Either way, what are the ramifications of this larger scrub radius? The front track with is 74.5" wide. The rear is 73.5" wide.

      What else do I have to consider? Turn radius? I'm using a 670 steering box too for what's it's worth.

      What measurements should I take and what should I consider before cutting the fenders apart? It's time now to get the outer ring of the 3pc wheels replaced with the original more narrow ring to make a 10" wide front wheel instead of 11".

      I don't know why everyone is caught up in going over board on such a large tire in the front.
      I'm not picking on you,but a 315 30 18 is plenty big enough for the autocross, road race stuff we do with these cars and trucks.
      The change in scrub radius is one thing to consider.

      I have 19s the only question is how wide they'll be. I had them at 9.5" wide I think, but I sent them back to forgeline and had them reassemble with a wider outer hoop to be 11.5". I'd have to also get more tires to go back to be more narrow.

      I can't speak to everyone else's motive, but my reason is for looks. I like the look. If the wide tires with deep-dish face.
