I can't figure out which wheels these are. The PO threw them in for free when I bought my car and I can't figure out if they're the Club Sport or D90 wheels. I read about a test where you can flick them with your finger and if they ring, then they're the forged Club Sport wheels. If they make a thunk then they're the cast D90's. I don't know how accurate this test is, or if it's total BS, but when I flicked them with my finger they rang. Here are some crappy cellphone pictures:

D90's

Without question, d90s.

Damn. I was hoping they were Club Sports. Does anyone know how much they might be worth? There are a few small scratches and some very slight curb rash on them. I've seen them go for $125-1000+ in the same condition as mine so I'm not sure what to ask for them.

$300

So how do you know the difference...?

Spot the difference....

Club Sport:



D90:



...and off course the weight!

much appreciated - I have a set I need to sell one of these days also. GLWS

They both look almost exactly the same to me... How much lighter are the club sports? These felt pretty light to me.

Look at contour where the spokes attach to the rims. The finish is also different - D90s are painted, Club Sports are anodized, which looks like bare aluminum.

I have never felt the Club sports are very light. I doubt they are much lighter than the pressure cast D90's. Maybe a little, but they are not significantly lighter like Fuchs or the magnesium turbo cup phone dials are.

Note where the spokes connect to the rim edge: club sports are flush, d90's inset.

Beat me to it! ^

They are about 1-1/2 to 2 lbs lighter per wheel depending on width. The easy way to tell the difference is that the CS have a scribed line around the outer spoke area.

btw the CS were also made by Fuchs so they have the fox logo on the inside just like regular Fuchs.

I was referring to the traditional 911 black centered 5 spoke forged wheels as a "fuchs" wheel. Those are relatively light.

My 9x16 club sports are approx 3.6 lbs heavier than std alum 8x16 phone dials.

W/ a 245/45/16 toyo RA1 mounted, the 9x16 Club Sport weighs 48.0 lbs. To compare, a 9x16 mag cup phone dial w/ a 245/45/16 R6 weighs 39.8 lbs, and a BBS E50 10x17 w/ a 275/35/17 R6 also weighs 39.8 lbs. R6s are lighter than RA1s, but a considerable part of the combined weight difference is the Club Sport wheel.

I have never owned a set of D90's to compare, but if they are 1.5-2 lbs heavier than Club sports, they should only be used for boat anchors.

8x16 Fuchs = 19 lbs (or less depending on offset)
8x16 PDial = 20 lbs app
8x16 CSport = 21 lbs app
8x16 D90 = 22 lbs app
