So are the little weights Micro? Are the MC weights Micro?

The small .25oz..5 oz. and the .75oz. ( 1/4oz. weights were not supposed to have been used by GM), were too small to emboss the entire word "Micro" so Yes the "M" marked are BADA or Micro weights. The "MC" pictured above would not have been originally installed on your 61 wheels according to Gary B. article.

I just examined an original spare from a 72 Cutlass, it had two weights on it. One "B MICRO 1.5" , and one "AS 2 ACRA AS 2" markings.

I'd go with the "M" or micro marked as they do seem to me to be the most commonly found, as well as being called out in the JG. I have not seen any "U" marked in the entire lot.

I agree with what Kevin has indicated. I will add one more thing - the larger Micro weights should have that little extra wing at the top that is shown in your first photo.

Guys,

Based on the C2 AIMs, 0.5 oz weights were used during the C2 era. Do none of the C1 AIMs mention the sizes of weights used?

Attached is an image of a period-correct, Bada (Micro) 0.5 oz weight.

Gary, Would it be safe to say the small "A S .5" would be a Sears weight? This was another high quantity weight found.

To add, the SEARS weight do have the "winged" tip, leading me to believe they're Bada made Sears embossed?

Kevin,

I have no idea about the S weights, and personally I would not say it's safe to assume they are Sears.

Weights can be found with many retail vendor names embossed on them, like Sears and Allstate, and they could well have been made by BADA or one of the other major wheel weight suppliers (like BADA, or Perfect), but to the best of my knowledge, Sears, Allstate, etc., embossed weights, were not used on the GM production line and would not be correct for judging.

Gary,

I don't have the AIM with me, but our updated judging manual specifies 0.50, 1.00, 1.50, 2.50, 3.50 and the maximum allowed weight listed in the AIM is 5.00.

Ia there a deduct for NO weights? It could happen.

No weights would not be factory typical and worthy of a deduct in my opinion.

Could one tire not need weights, I guess that could happen. However, you can bet that more then one tire without weights would receive a deduction.

Re: 1961 wheel weights - judging points

Did Corvette wheels improve with time? Meaning, would it be reasonable to find heavier weights on 53 - 62 wheels as opposed to 63 and up? My question arose from a weight buyer that is asking for ONE 2.5 oz, TWO 4.0 oz, and ONE 4.5 oz to balance the wheels on his 59 Fuelie.

Second question, these heavier Micro marked weights (3.0oz.+) that I have found do not have the "winged tip" more of the rounded end type. Are these the correct weight for a C1 with NO DEDUCT during judging?

Re: 1961 wheel weights - judging points

For C2, nothing over 2.5 is specified in the AIMs, and therefore nothing over 2.5 would pass judging. I doubt if 4.0 and 4.5 are allowed for C1. The AIM would tell.
