17" cup wheels on a C4S ?

[scaramanga]

Hi all, sorry if this is a totally ignorant q but does anyone know if 17" Cup wheels will fit a 993 C4S?

I know the wide bodies look good on 18s but I've just noticed the huge weight difference (vs my 18" solid spokes):
Front: 18lbs vs 25lbs
Rear: 19.5lbs vs 31lbs

So am just wondering - do people think the 17" wheels will fit (and clear the big reds) ?

Will it look wrong on 17's ?

Any views welcomed!

Hi

How is the project going?

Interesting my C4S has lightweight wheels, wonder when the model change was made as they are not listed on the extras.

Sorry dont know about the 17" Cup, I presume you mean Cup 2's, which would make it look like a std 993! I would buy some lightweights and then sell the solids.

If no one knows the answer, I have some Cup 2's which I could try putting on the car.

Hi there, As far as i know the wheels on the 993S will be a different offset to the cup wheels (ie they won't stick out enough on the back)
Mine has the hollow spoke 18" wheels. Front: 8J ET52. Part No: 993 362 13600. Rear 10J x ET40. 993 362 14000

Hope this helps

Don't know specifics on fitting, but am sure 17s will look awful on an S (just my opinion[]).

 

[Gordon Attar]

If it helps Cup 2's

Fronts are 7J *17 offset 55 part no 993 362 124 00
Rears are 9J *17 offset 55 part no993 362 128 00

The big reds though on the front are within half a centimetre of the inside of the spokes on the turbo wheeks

The wheel will clear the brakes but you will need spacers on the rear to achieve the look of a carrera s with it's std wheel ,which is a17" cup 2

As said above you will need wheel spacers for the back but otherwise will fit. The purpley grey C2S specials came with Cup 2s so there are widebody cars with them fitted.

+1, will look terrible

Didn't S's come with cups as standard, but the vast majority were spec'ed with the turbo hollow spokes as an option? I assumed there would be wide body specific cups?

I've only seen one S with cups and it looked good (but then I am a fan of the cup design).

 

[Gordon Attar]

Definitely standard on my 98 model, only extras on my sticker on mine is sunroof and tinted front windscreen.

See earlier comment from Ian ref early C2S

 

[lauris]

you will need large spacers on the back and shims on the front to make it look correct,

i had a loan set from dealer while they repaired by hollow spokes and they need spacers,

mine was sa 2S so no big brakes !

you would be better buying 18" hollow spokes, or lightweight wheels, although lightweight wheels are more prone to warping with pot holes !


scottie.

Further to my previous post, curiosity go the better of me...

...if I am reading the parts catalogue correctly:

There is an 'S' specific rear 17" cup which has an offset of 55 (compared to 70 on a Kylie) notably though the 17" cups are 9J versus 10J for the 18" rims.
The front 17" cups are the same for both J-Lo's and Kylie's, although again they are narrower than the 18" rims, 7J versus 8J.

S specific rear 17" cup part number is 993.362.128.00 whereas the normal rear 17" cup is 993.362.128.01.

So, if you can get the right wheels and they do clear the brake calipers on a 4S there should be no need for spacers.

Hope that helps.

Thanks all for the feedback above! And sorry for the delay in responding.

I basically was looking for lighter wheels than my 18" solids but this seems difficult unless you go for the hollows as mentioned above.

Now, the hollows seem difficult to source, so the alternative was to go for an aftermarket wheel (eg. Bbs e88's?) which can be pricey or the 17" Porsche route.

Funnily enough I actually think the Cup-1's look much nicer than the Cup-2's (just a personal view). Assume the Cup-1's would look wrong on a 993 ?

 

[38F3E1]

Just regarding the info on Cup 2s. I know that the sizes and offsets for the narrow body are 7J front with a 55 offset and 9J at the rear with a 55 offset. I believe the 70 offset rears are either the 8J wheel or were the 9J fitted on the very early 993 or one of the front engined cars at the time. 9J rear with 55 offset for narrow body is definately the more normal and later Porsche fitment.

The front wing width on both narrow and wide body are the same so 7J wheel with 55 offset is correct for the front of a WB.

The rear wing width on a wide body is 25mm wider (hence the offset difference on the 18 inch wheels of 40 vs 65 between WB and NB) so you would fit the 9J wheel with 55 offset and a 25mm spacer on the rear. Look perfectly OK on a WB and a nice light wheel with a more complient ride and cheaper than 18s.

Cup 1 is the best 964 wheel IMO and look better than a Cup 2 on a 964 but the Cup 2s suit the softer lines of the 993 better.

I don't have an "S" but do have big reds up front and RS calipers up back and the std cup II's definitely clear the calipers with no issue at all. If you want best looking lightest wheels go for the '02 996 five spoke wheels they are very light and look the dogs dangly bits in 18" I have these fitted for track work and std cup II's on 17 for road work.

Hi - thanks for the advice. I've heard a couple of other people mention the 996 5-spokes. Are they a direct fit ? Or would i need spacers ?

Also - do you happen to know what the weight saving is vs 18" solid-spokes (turbo-twists) ?

 

[jmspear]

if you look in this register under FAQ's all will be revealed,

http://www.porscheclubgbforum.com/tm.asp?m=112688

but to make it easy for you:

Making a good comparison to Turbo Look (solid spoke) as came standard on the Carrera 4S or as option 413 :

8x18 ET52 (Front - all models) .......993.362.136.01 - 25.57 lb
10x18 ET65 (Rear -narrow body) ......993.362.140.04 - 29.32 lb
10x18 ET40 (Rear - wide body) ......993.362.140.03 - 31.08 lb

Another possibility for narrow bodied cars is the MY 02 Carrera wheel. These are lightweight, look good, and come in appropriate offsets :

MY02 Carrera
Fronts 8x18" ET 50 19.3 lbs
Rears 10x18" ET 65 23.4 lbs

yes they were a direct fit for my 993 NB and a massive weight saving as you can see above, finidng a set is a different kettle of fish though ........

cheers

John

 

[scaramanga]

Thanks for that - sorry I didn't come across that link when I did the search.

So given the different offsets, will I need spacers on my wide-body to fit those MY02 wheels on ?

 

[38F3E1]

Yes 25mm spacers as the standard offset on a 10 inch rear on a widebody is ET40.

Ian.
