Can Porsche 911 turbo wheels fit on Porsche 968?

it depends. what you need to do is first to check the offset. the later offset that change over in 1987 is 55. i am running 17" 993 cup II rims, 7.5 front and 9 rear on my 87 944S fine. so check the offset. next check the rim size, 17 works fine not sure about 18 as you might experience rubbing unless you went witha lower profile tire
