S2 alloy wheel choices

[nick9one1]

I'm thinking of changing my alloys..

I currently have a set of Cup 2's with 205 and 255 rubber. I guess that makes them 7" and 9"? I'm not sure about offset as I haven't checked. I don't think they are original as the ET isn't stamped beside the valves.
What kind of price should I be expecting? - I've been looking on ebay and they dont seem to come up too often..

I think I will probably change back to the original D90's - am i right in thinking they should be 7" et 55 and 8" et 52.5?

Alternatively are there any other porsche alloys that come in the correct size and offset for my S2?

Thanks!

These are forged, like the Club Sport ones and quite rare in 944 offset 7" 55 and 8" 52. There are also 928 versions on the market but most of those are the wrong offsets.

I really like the CS Forged alloys on my s2.

 

[Copperman05]

Cup 1's are 16' and about the lightest available for the S2 (apart from rare mag teledials for turbo cup cars).

(not on 944 sorry)

I would say on an S2 it has to be d90's or cup 1's.Cs are nice if you can find a set.

 

[nick9one1]

ok my mistake, maybe I have cup II's

they look like this,

 

[Copperman05]

They are 17' cup 1s, cup 2's are slightly different.

ok thanks

So...... does anyone have a set of D90's and fancy upgrading to Cup 1's ???

The debate about wheels will always 'rage' as there a large number of options for 944 both those originally fitted and those available aftermarket or from other models.

Some points to consider aside from aesthetics:

1. Generally speaking the larger diameter the wheel, the greater the weight

2. 17 wheels will give greater cooling (larger gap between wheel and brakes) but need lower profile tyres - not sure of cost but I know most modern cars run on at least 17" or greater

3. 16" wheels are the factory fit option - offset, weight unsprung etc will be correct although I believe the range of 16" rubber is more limited.

4. S2's in early form came with D90's 7"at the front and 8" at the back. Later versions had an option code for 8" front and 9" rears and the later Turbo's had them as standard (those that were 89 onwards, not Silver Rose S but late model 250's).

So you could fit, if you can get hold of them a set of 8" and 9" D90's if you can get hold of them you could then put a set of 225/50 front and 245/45 on the rear.

Other option is to get hold a set of 7" & 8" D90's much more readily available and put 205/55 and 225/50's on.

If you or anyone else is desperately seeking a pair of rear 9" D90's I know of a pair in Harlow.

I might be . What sort of nick are the wheels in , what tyres have you got fitted , how much tread is remaining and how old are they according to the DOT code ? I've got a set of D90's on mine with almost new Kumho Ku31 rubber all round although the wheels were originally off a 911 so fronts are 6J rather than 7J . They still have the correct tyre size .

All the above is true but two additional points:

3a. There is a fair choice of matching tyres in 205/55 16 and 225/50 16. There is much less choice of 245/45 16 for 9" rears, if you also want the same make and speed rating of tyre for the fronts in either of the other two sizes.

4a. Don't forget there is also a 7.5" D90, which is the late Turbo fit. (7.5" front, 9" rear). So in theory you can mix and match from 16" diameter D90s in the following sizes:
6" (964 fronts), 7" (S2 fronts), 7.5" (Late Turbo fronts), 8" (S2 rears) and 9" (late Turbo rears)

Nice pair of D90's refurbed by Lepsons would be spot on imo.

But you changed yours, Edd[]

 

[nicksonmsport]

i have some s2 d90s off a car im currently breaking pm if interested.

 

[Frenchy]

Edd, was the Golf yours ?
F1 Hotel rooms booked for LMC St Etienne Parc Sud Expo $43 ish for a twin, cheap and cheerful but somewhere to have a beer or three and a kip !

 

[Copperman05]

No not my Golf, I've only ever owned Porsche's[].

Looking forward to LMC more and more..

[chrisg]

Good points well made ! Yes, you're spot on about the late S2 and Turbo Fronts at 7.5" - got them confused with my current set up = 4 x 8" all round to keep it balanced.

I have some nice Yokohama Advan's at 225/50 all round and the car is very nicely balanced.

You may find it's easier (and cheaper) to source 4 x 8" rears that will fit the front than trying to source the 7.5" fronts - 225's will hang out slightly on them rather than sitting comfortably on a 8"'s.

[Lowtimer]

225/50 is the factory standard fit on 7.5" on a Turbo and they don't seem to hang out over the edges on mine...
But yes, 8" are easy to get, being S2 rears, and will work fine on the front of an S2 or turbo. There is a lot to be said for standardising on 8" with 225/50 at all four corners.

I did hear all sorts of lurid stories about how 250 Turbos need 9" or wider rears with massively wide tyres to put the power down, but mine at around 300 bhp is no problem at all on 8" rears with 225/50. I've driven it a lot in the wet over the last few months and it takes full noise in second gear perfectly happily.

Would add that the "Dustbin lids" are the same forging as the CS wheels, just with less machined off.
