They arrived and are installed! And they definitely clear the ST-60 and ST-40 BBK's. Not the best pic but I am really liking how these fit and look and the NT01's appear very aggressive, even compared to the RE-71R's. I like em so much I am keeping the Apex "free advertising" wheel caps on even though I normally only do BMW wheel caps.
This was a killer deal on a great set of wheels. Appreciate Apex directly supporting our baby bimmer track cars. Can't wait to try it all out on the 18th!
For those wondering, it's 45# a corner. That's 5# lighter per wheel than my 18" stock wheels with Continentals and I imagine over 10# per wheel lighter than my type 135 wheels with Toyo R1R's (they are out of the house getting mounted and balanced right now, will weigh when I get them back). UPDATE. Confirmed. My type 135 track wheels and tires are 56# (!!). So I've now saved 44# of unsprung weight.
