Jerry, Point is well taken.... except in your photos the fakes are on the Right. Additionally if you use this analogy you would have to add the following sub notes:

- the wheels are only subject to rolling when perfectly polished and maintained & reminded daily of how good the polish looks
- you can only get so much wheel under the wheel well before looking awkward
- you may find them on the neighbors car occasionally
- the only tires they like cost $2500 each
- they can become so thin they are useless on the "track"
- when you wipe the brake dust off they say ***ch on the center caps
- you would have to return to the dealer weekly to have "balanced"
- no amount of balancing seems to make them "roll" true
- if caught sizing up Speedlines "track use" becomes severely limited, in many cases causes lap times to decrease
- after many years of use the rears are subject to expanding past the fender wells (see other photo)
- Trying on a set of Speedlines could result with only the fronts or rears but never all 4. Poor representation could net the Porsche space saver spare!
- As nice as 17's are you will always want 18's and perhaps 19's
- After many years of use and 3 resprays you will go back to 16's and think they are the greatest ever!

So which are the "real" Porsche wheels and which are the repos?

Haha, that's probably true J

A bit late to this thread, but just a side note; I stored the original Cup 2's that came with my S and fitted a set of 964 Cup 2's I had lying around spare - fitted a treat with no spacers. Drove like this for a while until I got a very well respected specialist (who re-geo's CT4's, GT3's, aircooled 911's etc) to complete my factory fitted M030 build with adjustable Koni's with a re-geo. I mentioned that for ages the car's steering had a tendency to tramline a bit and can he get rid of this. He spent a while checking all the usual. Then I just happened to drop in that the wheels were from a 964. A verbal slapped wrist I got - deservedly! There's your issue he said - the strut geometry design no longer aligned or working as well with the correct Porsche wheel offset. My biggest lesson on thinking I could simply swap wheels around despite them fitting well. Original wheels back on and shod with new Eagle F1 Asymmetrics and complete re-geo (plus a couple of bush replacements). Night and day driving. I guess my learning is only and ever to stick to the correct wheel (design, dimensions etc) as Porsche intended and designed to.

Now THAT's a discussion worth having. Here's a different take: https://rennlist.com/forums/968-foru...l#post12073431

I've come to really dislike 968 7.5" wheels because of the ET65. It leaves an enormous gap between the tire and fender! 7" ET55 from the 993 looks better to me and works just fine with a 225 front tire.

Since we're discussing Cup 1s, this is more like it: https://www.sonnenporscheoemparts.co...at/wheels-scat

Talking wheel preferences is very much a personal take. Bit like discussing engine oil recommendations!

Yogii

Speaking of which, My understanding is that Porsche recommends 10-40 weight oil. I think most Indy's use 10-30 weight.

There are always these. May be crap though, https://sierramadrecollection.com/92...er-p32667.html

For the 968 (and aircooled), many indies, here at least, seem to opt for inexpensive Mobil1 10W30. However, many feel that it is not for them and looking to go for higher quality (aka more expensive) oil. Personally I took the advice first from EMC Motorsports, who are a well known 944/968 endurance race car preparations specialists and Miller Oils. I stick to Millers 10W50 NT+ Millers are not the cheapest but they are used widely in the endurance and other motorsport arenas. EMC even advocate going higher to 10W60 for those tracking most the time.
