Just for you Oli, before cup 1 and GT3 18", I like all three, so I can change as i like

Thanks ... and just for me too!
That really does look the cat's pyjamas. Wheels can make a huge difference to the way a car looks, and I have always been a sucker for originality in terms of looks. (My old Mk1 Golf GTi always ran on Pirelli P-slots, and the late Mk2 had the BBS RA's ... both were a pain to find second-hand, but both were worth every penny ... I really am a sad old git aren't I!)
Oli.

Wow the car is looking absolutely mint Nick!! and it's nice to see the wheels polished up - looks like you've had them refurbished. I'm struggling to keep on top of washing the car let alone polishing and waxing it.
I think 18" wheels are about the biggest wheel that the 944 can take and even then I think it needs to be a wheel that doesn't have alot of metal in them, for example the 5-spoke 997 carrera wheels that Rick Cannel has fitted look the business, but I think if you had say an 18" version of D90's it would look too much. But as I said before you need to make sure the void behind the wheel is occupied by brakes or it just looks rubbish no matter what size wheels you have.

Sorry if these are stupid questions but here goes - if you put bigger wheels on than standard does it:
1/ effect the accuracy of the speedo? i.e. you might be going faster than you think?
2/ do you need a bigger spare?
Both these would not matter if the diameter of the wheel and tyre are the same and I suppose people tend to put lower profile tyres on bigger wheels so that might happen but can anyone help with the answer?

No and No
You've already answered your own question. When you fit larger wheels the tyre manufacturers have cunning designed tyres that are a lower profile so that the overall rolling radius is virtually the same so that speedometer accuracy and clearance under the arches is unaffected
If you do ya sums right as long as the rolling circumference is the same then the speedo will be just as accurate and hence the spare will be the same, you musn't make the rolling circumference any difference to the original and any good tyre/wheel supplier should be able to calculate the correct tyre/wheel size.
Really what you have to say is what were these cars intended to run on in the first place, people tend to forget, Porsche generally know what they are doing you know! 18" wheels were very rare when 944's were the norm, in fact no porsches at all ran on 18's. 16" wheels are an excellent compromise for the handing of 944's even 17" wheels compromise and make the ride a bit harsh IMHO!!!

I think you'll find that you can rarely get the outside diameter of the wheels bang on so you need to choose a tyre size so the outside diameter of the wheel to be as close as possible to the original wheels. Ideally, if not too far away from the original size, you want the diameter to be on the smaller side as this will mean the speedo will be over-reading your speed, i.e. reading faster than you are actually going, so you shouldn't get into trouble with speed cameras. Also you need to be within a certain % of the original wheel size or it can screw up your ABS.

I presume then that you have had no issues with the 17" wheels you put on? Did you have to make any changes?

I replaced the castor mounts to the 968 ones and noticed that the handling with my 17" wheels plus castor mounts was sharper than the 16" wheels with std castor mounts. However I am under no illusion that this anything other than an unfair comparison as i'm sure I would have noticed an improvement on my 16" wheels if I replaced my 19yr old castor bushes with new std ones. I have no problems with the handling of my car on 17" rims.

What do you all think these might look like on a 944?
