    Thread: 5x100 to porsche 5x130 specs

    1. 08-15-2012 11:17 PM #1
      I have pretty much all the specs I need. I was just wondering if anyone knew the actual diameter that they need to be?

      You could probably answer it better than we could. What car are they going on? how much brake clearance do you need so they don't hit the calipers? What size is the pad diameter on the wheels? Have you measured any of this?

      I would say around 160mm would be about right.

      If i knew the wheel pad dia. I wouldn't need the dia. of the the adapters. lol 160mm sounds about right though. If got clearance, offset all that stuff down. Was only missing the total dia. I don't have any measuring tool that fits inside the mag and is able to extend that much to measure.

      Thanks!

      30mm gap for what?

      It would be 30mm from the center of the stud or bolt hole of the porsche pcd to the edge of the adapter. Depends what way you're going to mount the wheel. But either way it's far from impossible.

      What's the clearance from your brake caliper to the center of your rotor/axel?

      It would only be 15 mm, from hole center to edge (radius, not diameter). Esp w/ Porsche using 14mm studs/bolts, I would not be comfortable with that, esp on a track.

      iirc when I looked it up most porsche spacer/adapters are ~175 mm (use 7" wide stock instead of 6" wide)

      Ah, well, I guess people are doing that then.

      Did some looking, apparently 42 Draft designs does 6.375" with a back cut. See the very end of the page on this link, cool pic detailing brake clearance. http://www.42draftdesigns.com/tech/adaptorfaq.html#130

      Other sources have anywhere up to 175mm OD, but not necessarily for 5x100 fitment.

      That bevel is normal on wide adapters. H&R has been doing it for years.

      Anywhere between 160 to 180 OD is normal enough depend on your application. That's why it would be best to measure everything up and then decide on the size you need.
