Do I have 7s and 9s (or 6s and 7s)?

Over on titanic there is much confusion about the width of wheels. Below is what a narrow body with 7/9s looks like. If your car does not look like this it will have 6/7s (except for the somewhat rare circumstance of 1989 cars with 6/8s) - most likely anyway!

Another picture of 7s and 9s - a little tough to see the dishing on this picture but every little bit helps. BTW a pair of 8s look almost the same as the 9s (but for recessed lug nuts).

And another. This one is BTW one of my favourite 911s of all time - it is uber cool.

Here is a normal sport model with 6/7s. I pinched the photo from another thread. Note how far inboard the 7s sit at the rear and how "flat" the 6s look at the front - there is virtually no dish to them.

And one more of the narrow rim variety. This car looks like my car used to look before it went to the dark side...

Having seen the pictures of 7s and 9s, would like to consider doing the same to mine that currently has 6s and 7s.

Can I simply move my rear 7s to the front, and buy 2 new/used 9s for the rear ?

Are there issues with arch rubbing ?

Does the handling improve / degrade / remain as is.

Do I need to do new alignment etc.

Would the pair of 6s be easy to sell (offset some of the cost of the 9s) - mine are nicely polished Fuchs.

Anything else I should consider ?

Thank you, and great looking cars.
 
Ian,
They should fit just fine. If you stick with 205/55 16 and 225/50 16 you won't have a problem. Some people have had problems if their suspension has been significantly lowered and running 225/50 and 245/45. Either way problems are sortable by 'rolling' lip of the wings and a bit of minor oil pipe moving. I would very much doubt this will be necessary on an '86 car. I'm running 7" and 8" at the minute and did as you suggest ie sold the 6" to offset the cost of the new 7" (already had the 8" on the back). Speak to Brian at Jasmine Porschalink who will buy and sell (he's not got any 9" at the minute though !). As stated above 8" look almost identical to the 9" from the outside, the extra inch is offset on the inside, so might be worth considering ?

I'm currently looking for another set of 7" and 9" to use as track wheels so if anyone hears of any for sale I'm interested too !

Be advised, 6s are worth virtually nothing right now but a pair of 9s will be £600-1000, if you can find them. They are very rare. 8s are a little easier to come by. New 9s are available from Essential Simon for something like £600 each.

The sevens up front are fine with 205/55s but you may still need to roll the LHS wheel arch and/or add negative camber - each car is unique but it is generally the LHS that rubs if at all. There is no reason to move the oil lines for this set up as there are other solutions if the RHS rear wheel is a close fit (it should not be). I found a 205/55 on a 7 was fine with about 1 degree negative camber ie., a little lower than standard euro height. A 225/50 on the same set up *just* rubbed, particularly with a heavy passenger. With 1.2 degrees negative it was fine. Now I have 2 degrees negative and will run a 225/45 on a 7. BTW, the 225/45 will fit better than a 225/50.

If I may be so bold as to offer a cheap solution, it would be this. Run 7s all round using 205/55 on the fronts and 225/50s on the rear. You will also need about 20mm of spacers in the rear to push the rears out properly. Very few could tell the difference between this setup and 7/8s if you are just after the appearance and a pair of 7s ought to be no more than £300.

HTH but YMMV.

Richard,
I could go with 7s all round, it would be the 'cheap' option, but I'd really like to get a set of 9s or at least another set of 8s. We'll see, I'm not desperate yet. Definitely not so keen on the idea of aftermarket wheels following our last meeting at Bedford !!!

As far as 6s being worth nothing, Jasmine gave me about £200 for my fronts IIRC ? Which I didn't think was too bad. I'll just have to keep my eyes peeled on e-Bay and the small ads as 9s do appear for sale every now and again !

Hmm... I sold my 6's to a chappie in a 912 who was looking for the correct wheel for his car. I would not say they were as expensive as 9" wheels, but they made a nice little sum for me. !

Steve,
I take it that you're now running 7's and 8's from what you've said on the thread and the look of your avtar (which incidentially I've admired for a long time). Did you just swap your 7's over and move them to the front ? I once saw a car that a friend of mine did this too and for some reason that I couldn't put my finger on it just didn't look right. I always assumed that there were 7's available with different offsets...... But it sounds like I'm wrong.
 
Thanks for the kind comments.

As delivered, the CS came in MY 1988 (*J production) - with 6" fronts and 7" rears. I understand that this configuration is standard. However, for MY89 (*K), then I think Porsche moved to 6" Fr and 8" rears. In speaking with a bunch of CS owners, and other folks, it is often mentioned that the steering of the 911 3.2 can be somewhat light...

Therefore to offer a little more feedback, I opted to shift 7's to the FR and dispose of my 6's. Also, the front of the CS is even lighter... Collapsible tubes instead of shocks, no underseal, no fog lights, no headlight washers, and a different front bumper. Even now, at speed, I can feel the front getting lighter.

Francis Tuthill remarked that If I thought the CS was light @ the front, I should try some of the earlier marks with 5.5's !

I bought new 8's for the back and had them re-furbed from Pristine Wheels at £75 a pop, all in.

Thanks for all the replies.

Will look to move the 7s to the front (using existing 225/50 tyres until need replacing), sell my 6s and buy either 8s or 9s. I am on a budget (who isn't!) so will take my time until they come along on ebay - will also contact Jasmine.
 
I am surprised that you guys have managed to sell your 6s. Jasmine once told me they were worth zero/zip/nada, but I guess the market changes from time to time.

BTW, if anyone wants to ofload a pair of 7s, I have cash waiting.

BTW II, there is nothing wrong with aftermarket wheels per se, you just have to get the right ones. Rather than looking for more Fuchs I have seriously thought of getting a set of 17s (3 piece and correct offsets) for track work, simply because you can run a bigger tyre and have a much better choice of R-compound tyre (brand and size) for 17 inch rims. The US Kinesis and HRE wheels are beautiful and Aussie Simmons are close behind (at a very reasonable cost).

Chris,
Looks like IROC bumpers, aero mirrors, '73 Duck Tail and sill covers removed......... lightweight spec I reckon!!
 
100% correct Chris. Top of the class for you.

They are Ruf CTR bumpers with a twist. They have brake scoops either side of the centre opening whereas the original Ruf piece had foglights a la 3.2 with rectangular holes. Mirrors are Ruf or racing as per 935 etc which require filing the hole in your door panel where the original mirror is mounted.

Phil, take a look at Nick Moss's early911.co.uk website for picks of his IROC/RSR replica. They are similar but these are definately Ruf pattern.

Very lightweight - race seats, fibreglass duck, no sill covers etc. Me like [:D]

9" Fuchs crop up regularly on US and German ebay. The shipping may wipe out the benefits of the strong £ to $, but at least they are available.

Arrrrh yes, I should have recognised them as I have a picture of the RUF 'Yellow Bird' on the wall next to my desk!
The wheels fitted to the CTR look great on 3.2's, a good alternative to Fuchs, not sure about the cost though.
