Cup one wheels

[chrism964]

Hi all.

I have just dragged my set of cup ones down from their hiding place in the garage. I am running on D90s as the extra sidewall height on the tyre gives a better ride.

I notice that I have different part numbers for each wheel.

965.362.124.00 - Front 7j x 17

965.362.124.01 - Front 7j x 17

965.362.126.00 - Rear 8j x 17

965.362.126.01 - Rear 8j x17

Fortunately they all look similar even on very close inspection (corroded and in need of a refurb).

I just wonder whether I need to go on a hunt to get matching pairs i.e. 2 x 965.362.124.00 and 2 x 965.362.126.00

Or should I just not worry? I didn't notice an issue when they were on the car (except they looked like crud due to the powder coat lifting).

I just wonder if the wheels are different weights? I suppose if I can be bothered I will weigh them.

Any opinions appreciated.

Chris

I wait to be shot down here but won't the difference in number signify near side and offside? I.e. They are a set with 00 being one side of the car and 01 being the other? Cheers Mick

The face is identical but spoke backs are different .01 spokes are thicker in design and also weigh more. Which may be an issue.

Interesting one mld... not seen that one before. From what I see in the PET catalogue I thought 00 and 01 denote opposite sides of the car and are often marked as such - L/H or R/H (catalogue not in front of me so can't say which is which)...

 

[chrism964]

spoke backs are different for 00 vs 01. front wheels weigh the same. rear wheels 0.5kg difference between the two on my bathroom scales..............

The last 2 digits denote a change/modification, whether it be some small detail, manufacturer or manufacturing process. From memory and as mld has pointed out, I also recall the back of the spokes looking different also the inner rim edge having a lip and the other not. Not sure which was which will have to check mine.

Link to wheel weights http://www.944racing.de/wheelweights.php It would appear there is a 600gram diference between the two rears, 01 being heavier than 00. Fronts are same weight and so should be no problem with a mix..................

Must admit, irrespective of weight I would want both wheels identical! Some don't but I do Perhaps that's the ocd in me [&:] []

Paul ocd, when was that diagnosed.......[] How do you manage when they balance your wheels and one wheel needs 50grams and another 25grams an another 30 etc....... I bet you can hardly sleep [8|] OP, you have a mixed set, but the fact that the main Part Number has not changed means they are interchangeable. (the .xx characters are variants of the Original design which occurred during the component life span. Its the only way to manage the component variants.) If the wheel spec was not interchangeable, a new Part number would be issued. If you are worried, I will take them off your hands for 50quid I did'nt think so.[] George

I think that diagnosis was just some time before some chap named Mr Elliott bought some shocks from me! [] But perhaps it was a misdiagnosis as I would not be bothered about the balancing weights []

I am glad to hear it [] George
