FUCHS OR CUPS??

[nick3814]

[8|] Having only owned my 911 sc since July 2005 I am very fond of my polished fuchs which are immaculate, however I cant help thinking, having seen several of our cars and carreras on cups that these look very good too.
Are cups all 17" wheels, does the geometry need altering, what offsets are required?

Not sure I want to change them however I would appreciate views, pros and cons etc.

cheers

Aesthetically I prefer Fuchs, but Cups look OK too.

I think Cups are 17" & so might give you access to a wider range of tyres if your tracking the car, but you'd probably be increasing the unsprung weight, especially if you get replica's.
I briefly ran mine on 17" Boxster wheels on track but I needed big spacers. The wheels were very heavy too.

I owned both when I had my 911. Tracked the car on both of them too.

Fuchs all the way!

I've seen some of the cup wheels painted in a satin/chrome finish and to me they look ok on the early cars . However any wheels that fit without spacers will be non original copies and heavy. The original porsche cups require large wheels spacers to fit our cars.

Hi Nick
My LHD SC came with teledials when I bought it & I was looking for a set of Turbo Fuchs.
After a few months looking I got impatient & hated the teledials on a 911 anyway (ok on a 944) so I ended up buying a set of 17" Italian made, mille miglia turbo cup replicas.
They were meant to be temporary until I found the fuchs but two years later & I kinda like them []

They have 225 on the front & 255 on the rear but I think 215 would have been better on the front as I had
a few minor clearence issues to begin with.

I think you'll find most people on here prefer Fuchs on these cars though []

Those look smart doug, I had a set the same size as those on my 944 lux and loved them.
So am I right in thinking that what ever cups I could fit they would be a lot heavier than fuchs as I think I am getting a bit obsesed with weight having stripped out the old heater motor, air pump etc.

 

[dugsud]

Yes, I would imagine any 17" wheels would be a lot heavier than Fuchs.
I know that even the 15" teledials I took off with narrow 185 & 215 tyres were noticably lighter than my cups........but the car felt sooooo much safer with the new wider footprint!

I really don't think I could go back to the skinny rubber []

Hi Nick,

My car had 17" Cup 3 wheels on it when I bought it (The same as doug's - made by Mille Miliga) I took them off in favour of 16" fuchs because I wanted an more original look (like the poster I had on the wall when I was a boy!)

I didn't dislike the Cups at all, I think that it makes the 80's 911 look more modern, but it just wasn't the look I wanted.[]

On changing the wheels I did notice several things: firstly as others have said the replica Cup wheels are much heavier than genuine 16" fuchs or 15" ATS cookie cutters, I dont know if genuine Cups are lighter I would imagine so, but you will need spacers to fit which will have some weight to them (as they are quite large & expensive on the front!)
I was also advised that using the 17"s can wear out older wheel bearings more quickly (which it did!) because the load on the bearing is shifted due to the extra weight & the wheels basicly sit further out from the discs than fuchs or cookie cutters.

The cups I had were 7.5 x17" on the front & 9 x 17" on the rear, then changed to fuchs 6x16" on the front (now changed to 7x16") & 9x16" on the rear. The ride was noticably improved with the 16" wheels along with the steering being much lighter, and also the tendancy for the car to 'tramline' disappeared - I don't if others have found similar results?

Th standard wheels for early 993's & some 968's were 16" Cup style wheels in 7" & 8" widths with 17"s being optional extras (see piccy attached) Also the 5 double spoke boxster alloys are 16" too, both of which I have seen on a number of 80's 911's both of which look good too. I would imagine you need spacers to use these wheels as with the genuine 17" cups but you would have to check.

I hope this helps.

Absolutely, the Cups just do not look right with the older cars. strangely though the turbos look better, but still not as good as the original Fuchs.

I think the older cars look GREAT with 'cups', 'twists' etc. The weight penalty for such a move is about 5k per wheel. If this bothers you look around for the much more expensive wheels but light racing type wheels from the likes of Simmons. Parr MS had some carbon Dymag wheels at Brands on the GT3s (18-19") , they may be manufacturing in 17" now , they were literally as light as a feather but were 2k a set.

Here, here... Personally, I think cups look strange, even on the newer cars because they "stick out in the middle too much" (very technically speaking, of course).

Same car on fuchs:

They are 7s & 9s btw.

It's a matter of persoanl taste. I much prefer Fuchs - to give that original 'retro' look. However I would definatley use cups on track days.
Now, would I choose Cup 1's, 2's or 3,s.......

If you use cups it looks way better if you teardrop the mirrors , cups and square mirrors look wrong .
Mark ( 911SSE) had this on his car and they matched well
I'm sure you could get someone to photoshop a sideview of your car to give before and after images.
