After several searches I haven't seen any sort of a "reference" thread for wheel weights as I've seen on other boards. So I'm starting one. :D Please contribute any information you have. For the sake of consistency, try to weigh the wheels without center caps or wheel weights, or at least specify if they are included.

I'll try to update the table periodically. Please put as much info as you can into your posts! Thanks, Jason

The Quad/S4 15" Phonedial is 22 lbs

That's with center cap and weights, so be sure to account for those extra couple of ounces :D

that means the campags are almost 2kg per rim lighter than the BWAs (high mag content) - not to mention stronger - BWA surely stands for Bent Wheel Association!

This thread is a great idea. I would only suggest that wheel size and offset be included when posting. After we get a few more replies we should compile into a chart.

Good idea. I just added that info to my post, and I would also suggest that we stipulate the years when the wheel was offered.

I've edited the first post to include that info, and formatted everything into a nice table. I'll try to update it periodically.

Can you describe these wheels a bit better? I think we have the first and fourth captured in the table already, but I don't know all the sizes / etc. for the others.

Thanks,
Jason

I added the specs for the wheels on the back of the IAP catalog. If anyone has weights for them let me know. The Rota RBs are listed at 13.9 lb by Centerline but 15 lb by the manufacturer.

Something here does not add up. I had a set of BWA sportstars and a set of mid 80's Daytonas at the same time. I don't remember the exact weights but I do remember that the BWA's were each about 4 lb lighter than the Daytonas. You could easily tell the difference just by picking them up.

That may be true, or there may be production variations over the years. I'm happy to change data as better info comes in. I was also thinking it might be a good idea to break the table into three posts, one for 4x108, one for 4x98, and one for 5x98. Thoughts?

Breaking them out as suggested makes good sense. Also, would it help if these were listed in chronological order, and all OEMs together followed by the aftermarket varieties?

Best regards,

Alfa may have had multiple manufacturers make the OEM '80s Spider alloys, as they did with most of their other OEM alloys, like the Turbinas and Phone Dials.

IMHO - this may be arguing semantics - but I think the Cromodora CD-35 wheels should be called "Daytonas" and the '80s OEM wheels should be called... something else. I'm not saying Alfa never referred to the OEM wheels as Daytonas (they did, occasionally) but rather that it's confusing and not altogether appropriate.

Remember, the basic Cromodora wheels that led to all the Cromodora variants (CD-35, CD-31, etc.) was first seen in 1967 on the Ferrari Daytona, hence the name!

73 Cromodora Daytona

I have a spare "April '73" Cromodora Daytona that weighs 12 pounds (no weights or stem). It is a CD-35 14"x6" JK. it is 22 mm offset and 4x108. By contrast the current IAP CD-35 repro (KBA 43907) weighed 4 pounds more at 16 pounds (with stem and 4 weights). Neither have centercaps.

I've been told (and debate rages) that pre ~86/87 CD-35's were higher "magnesium" alloy versus the later ones an "aluminum" alloy. I have 4 ca. '84 CD-35's but cannot get their weight since they are mounted. Your list may need to differentiate between these. Regards, Bruce
