I'm looking to buy a set this week of Rota RB's for my 72 240Z. I want to put on 225/50-16 all the way around on 16" x 7" or 16" x 8" RB's wheels. I've looked at all the past forum's on the subject and I get lots of different opinions on what should work. Can someone please just tell me what will work EXACTLY with the stock suspension and when i put a set of Eibach progressive springs (lowering the car about 1") later this summer. Which offset should I get. I want to fill the wheel well without any rubbing or having to bend the lip's up or adding wheel spacers.Thanks for the help.
