Sure, those are Dymags, imported here in the USA
by Rennworx. I used to work with Rennworx owner,
Bill Koenig.

They are certainly lightweight and well-suited for
racing applications. I know they've had leaking
issues on the Mosler MT900 applications; the trick
is to get the carbon fiber rims to have enough resin
impregnated that the weave doesn't leak. I've seen
a few leaky wheels already; Dymag is good about
replacing defective wheels, but you have to wait
for more to arrive from Europe.

You guys know they're $1800+ each, right?

What happens if/when these wheels fail? I've heard that CF just breaks or cracks unlike steel/aluminum that bends. I wouldn't want to experience a CF wheel failure at high speeds, although I'm sure the manufacturers have accounted for that

yeah if i was to save weight through wheels, i would get some lightweight forged BBS rims instead of CF wheels because CF wheels would crack instead of bend
but then if i have rims cost that much, i would drive slow and take it easy
but then it would defeat the purpose of getting lightweight rims

U gotta live in a area with no bumps, dips, potholes, rail road tracks, and sewer caps to be able to drive around on a set of those carbon fiber wheels

Well... that's a fairly generic statement.

What does one mean by strong? Wheels must cope with
different stresses than, for instance, a trunk lid. Fatigue is the
killer of wheels; carbon fiber is different from using an alloy,
in some ways better, in some ways worse. You must weigh
the pros and cons of weight, harness (brittleness), radial loads,
cornering loads, heat dissipation, material consistency, quality
control, etc, when building a wheel like this.

Also, about Magnesium... it certainly has its' pitfalls.
For what it's worth, BBS has discontinued making Magnesium centers...
Don't get me started on Magnesium!

if i have rims that cost soo much, i'd probably be able to buy a new set every month to replace the broken ones.
