none of the suspension experts offering advice on adjustments that will bring the top of the wheel in ??

 

Hmmmn - so 41mmm minus 6 is 35mm.

This is what I reckon I must have then.

Don't fancy faffing with camber too much as I'm bound to wear out those covers faster!

I'm going to be on the phone to signor supplier first thing am!!

 

Julian,

Those BBS wheels look like magnesium-centered racing wheels - is that what they are? If so, you won't find any 'et nn' on them, as they are custom built. If they are BBS racing rims, I'd caution about their use on the street. They are very light, excellent on the track, and very rebuildable, however, having owned a set, I wouldn't drive the magnesium-centered racing wheels as a street wheel - too easy to damage. If that's what you have, let me know and I can give you some more pointers on where to watch for wear - they are not put on and forget about, like, for example, most one piece wheels.

For offsets, on a narrow-bodied 964, 9" to 10" offsets will be in the 52mm-44mm range. Jeff mentions 42mm offset from Fikse, however, he'll have at least 2.5 degrees negative camber, and if he goes with 275 tires, he 'may' find he has to roll his fender lip. If the offset is greater than 52mm, you might need to use a spacer, i.e., if you have a 54mm offset on a 10" rim, a spacer of 7mm would move it to 47mm.

Adding more negative camber will pull the top of the tire in, however, with the RS your negative camber should already be around minus 1, give or take, degree.

 

It will take minus 10 neg camber to get those wheels in.

Indeed they are the mag racing rims and indeed they were custom built - but it is clear now that either BBS or my supplier has got something very wrong.

So - with regards to fitment - can you give me the exact spec of what these wheels SHOULD be to fit my RS nicely - both front and rear.

As I said, I think I have 38mm offset on the rear which is clearly not right!

(Also those tips on care would be great!!!)

Cheers

Jue

 

Update!

Well, it looks as though BBS have sent a 30mm offset wheel (! DOH !)

My supplier is being helpful though which is a godsend because the last thing you need in a situation like this is a recalcitrant supplier!!

They are air freighting my wheels back to the factory and I should have the replacements next week..........

Fingers crossed

And many thanks to Ian for his help on this - very kind of you mate - I owe you one!

Best regards

Julian

 

That's what this place is for.

AND why it's so great.

 

I would recommend 52mm offset in front, and assuming your rear wheel width is in the 9" to 10" range, I'd want 47mm (although roughly 50mm to 44mm can work).

On BBS racing rims used on the street: They are very lightweight and are easily damaged. You need to periodically clean the back of the wheels and look for small cracks between the bolt holes. When you find any, you need to replace that half of the wheel. Over time, the seals will need replacing, and at that time you should install new bolts. When replacing seals, you need to be sure that the mating faces of the wheel halves are sound, and have not had any grit get in there which cause small scratches in the metal, affecting the sealing ability. If any questions, you replace that half of the rim. I'd be sure to wax the polished aluminum rim as soon as they get the right size to you.

 

Bill is spot on in regards to Kenises, Fikse and BBS RACING wheels...the ET is usually not evident (marked) on the inside of the wheel as a 3-piece wheel can be easily modified with different sized wheel halves.

I meant to comment on that earlier, when it seemed you and Ian were going to look for #s inside the wheel.

Yes, 30MM is a bit too much...1/2" (12mm) to be exact!

I have yet to find out the fitment on my NEW Fikses, but hope the 9" fits better than the 10" ones did. I may be off regarding the offset (going from memory) and they may be more like 47mm, will have to check that again with the paperwork.

I do look forward to fitting a 275 series Hoosier back there NICELY, for a change.

 

Well thanks for all the support again everyone - I am looking forward to next week and will post a few pictures and a driving report once I get the thing up and running!

I don't think I'll have any longevity issues with the wheels really because my car does a ridiculously low mileage and only a couple of track days a year and it is always so clean you could eat your dinner off it!!!!

Perhaps I should invest in a garage ramp though!!

PS If the world operated like car owners forums it would surely be a more efficient place!!

 

imagine having a momentary lapse in taste and buying these , only to find they do not fit !!!

£140'000 for a set of four 18s!

The 18in rim is chrome plated and features 19 solid gold screws. In each screw is a 1-carat diamond gem, making 19 diamond carats per wheel.

AWR and jeweller Gerard Chopard Guillaumont build the rim, which takes around 100 hours to construct. A set of four wheels takes three months to complete

 

Ian,

Pimp wheels!!!

more suited to a Cayanne I feel.
