As others said these weigh 27.5 pounds more than the 10 X 18" speedline. Not sure I would find a benefit since you can run a 275 on the 9" wheel using 15mm spacers with less weight.

As Cupcar#12 said....they're strong.

The design of the cup1's are all the same unless we compare the 7" 965.362.124.00 against the 965.362.124.01 or the 8" 965.362.126.00 against the 965.362.126.01 which have different spoke designs as viewed from behind. The added weight of the 9.5 comes from additional material and not a design difference. The 9" cup 1 weighs 25.96 pounds so it is just added material on the lip. The Speedlines IMO are as durable as the Cup1's although the original Cup versions had issues with the centers cracking this was revised and the newer wheels did not have this issue. You can tell the old style vs the new by a change to the center casting viewed from the back and the valve stem was in the center of the spoke on the wheels that had issues vs the center of the 2 spokes of the improved design.

I have both cup 1's and speedlines and both are equally strong wheels.

Forgive me for bumping an 8 year old thread, but there is a lot of good info in here.

Cobalt, do you happen to have a picture of the 2 versions, or perhaps of a crack to an earlier version? I could not find any for reference.

Also, can anyone confirm that the 964 cup cars used turbo trailing arms on the narrow bodied cars? If so, was it just to fit a wider tire?

If so, has anyone fitted a 9.5" rear on a standard 964? Or does any have a 9.5" rear with a similar offset that could shed some light on the potential fitment?

Cupcar#12

going off of memory (i need to dig out the old cup parts list to verify at some point)....
too bad the new registers of the Cup USA PCA group have not put the site back up that i know of... I had pictures, parts sheets, the lot up there.

The CUP USA edition used narrow body trailing arms (Banana arms), with a rolled fender lip.
This allowed the use of longer studs and a 20mm spacer (Need to check on specs here but believe 20mm... just don't quote me on it) - the wheels were stock Alum 9.5 Turbo wheels and a 275mm tire. (at least i fit a 275mm). The spacer was a motorsports part (andial really, since the cars had to come in with stock Federalized spec wheels, and other systems, since they were brought in as "Normal" C2's)

If you roll the fender lips you should be fit the 9.5 wheels in the turbo offset, the stock 8" rear wheels moved to the front and used a 235mm tire. no spacer.

The front lips also needs to be Rolled.

My car is running 9.5's in the rear. I believe the spacers are indeed 20mm. Extended wheel studs as well, but I don't know offhand by how much.

8's up front.

All the benefit of the PO's hard work.

Are those prices for real? How many will they sell at those prices? None, then scrap the whole "Classic" parts experiment?

I wonder if Sunset could get these at more realistic prices...

EDIT: Sunset saves you $215/per but they're still over $1k/ea.

What I find most surprising is that the more common 8" wheels are listed at $1502.30 each but the comparatively rarer 9.5" wheels are listed at $1257.69 each.

Doesn't really make sense.

Did the Turbo come with 9.5's as well? I was under the impression only Cup cars had 9.5 rears.

Thanks for the info #12.

EDIT: Funny, #12, it was actually your post from earlier in this thread that left me under the impression Cup cars used Turbo arms. What did you mean by "wheel carrier?"

pu911rsr

The 9.5's only came on track converted US cups, I assume the euro 964 (M001) cups ran these through 92. The rear oil line was also flattened so these would fit correctly. They used a 21mm spacer. $1k ea. for the 9.5's new sounds like a steal to me, I wouldn't sell my used spares for that price.

I haven't been around for a while.

I don't have time to read through this again after 8 years. If we are talking 17" cup I's they could be optioned on the 3.3turbo.

Not sure where the pics are I will look for them. I have posted the two types in detail on another thread someplace

Not sure how the rear trailing arms of a turbo can be fitted to a N/B car. They would stick out far too much. IMO they are the weakest part of the turbo design a widebody with narrow rear trailing arms is a much better option.

If you want pictures let me know what wheels. It is probably easier for me to take new ones. I have the different 00 speedline and 01 SM version 17's all sizes along with the 18" 8, 9.5, 10 and 11" factory speedlines.

Not sure why Rich has not updated the info I know he was working on it.

My guess is that they don't actually make them any more. So price is based on how many they have left over.

MRH

My thought too. If someone buys them could you post the date codes?
