The look of the the original set up from the factory with the 8 inch rims it just not quite the look that I appreciate! It reminds me of a Funnycar - just to far recessed into the wheel house! (and changing to 10 inch rims is not an option-way to expensive)

I used wheel spacers on the rear axles on my BMW E21 Alpina and in my 1974 911 Carrera (drove my 911 for 18 years on the German Autobahn) and I always went with the “bolt on “ style. It just made more sense to me.. I consider them safer than the slip on spacers on the longer wheel studs! The longer a bolt is, the more it can stretch, twist and fatigue! I know they are people who think different, but this is my reasoning.
(And nothing or nobody can change my conviction because I have many many aggressive miles done with this setup) When using the correct materials , I do not see how they can be an issue! (From china it would be very questionable)

So, for my car I ordered Wheel spacers Pantera specific (listed on their website) from Germany (SCC Fahrzeugtechnik GmbH, www.spurverbreiterung.de), they produce quality products with the TUV certification (which is a rather high standard)! They also make spacers for race applications.

I ordered 25mm spacers and as I know now I should have ask for 30mm.

reason for the additional 5mm is that the (original ?) studs on my car are 30mm protruding and with the spacer mounted the stud would touch the rim!

it would be possible to grind the studs down… there are no threads on the last few mm…

the rim original has a small recess in the mounting surface (5x)  where the stud would be but it is only about 2-3mm deep! I opted to machine the recess down to 6mm. All round edges and there is plenty of meat!

And yes, it is a magnesium wheel.. I did take the machine shavings and lit them on fire 🔥 and just add water… what a show… reminded me of the chemistry days at school. (Its not pure magnesium but it lights up)

I did point the magnesium issue out to my machinist because I knew he has to take special precautions working with it!

The spacers fit perfectly centered on hub and wheel!

The wheels look like where they belong-now it’s a nice A@@ 😁

Hi Lemans,

The fender arch rim is about 18mm thick and the closest clearance on the outside of the fender to the bulge in the sidewall of the tyre is around 40-44mm so with a spacer of 25 mm you are just inside the inner fender line if the suspension is fully depressed. Looking at your set up now do you think it can take another 5mm of spacer thickness ? How much fender to tyre clearance do you have with 25mm?

Can I also ask the approximate cost of the spacers and the amount you have left with respect to fender / tyre  clearance ?

Thanks

I hopefully get it done back on its wheels by the end of next week… still have to finish up a few things and then go onto electric and for that I’m gonna drop it back on the ground!

I missed taking measurements and taking pictures when had it on the ground. my fender lips are rolled in… (that’s the way it was when I bought it) on top of it, it depends what size tire you use..

price was about 180 Euros .. can’t beat that

I have a set of 10" campis on a stock bodied car.

It seems they split their extra 2" of width as about 1.25 inches more to the outside and .75 inches more to the inside as compared to an 8" wheel.

A 30mm spacer ought to put an 8" wheel at just a couple mms shy of the outside of a 10" wheel.

We tried a set of 1.25" spacers like yours with 8" wheels on a friends car and it looked pretty good. Rolling the fender lip is encouraged with 295-50s. The stock studs tucked just inside the spacer and cleared the backside of the wheel flange fine.

Thank you very much.

I call this a confirmation!

That is precisely what I thought!

I wasn’t thinking of that issue when I ordered the spacers! Only after I mounted one spacer and saw the stud protrude I looked at the backside of the wheels and started measuring! Live, and learn!


yes! There was interference! I measured it out and that’s what I came up with…just measure the stud length, and then look at the back of your wheel and measure how deep the recesses are between the bolt holes. I came up with that the recess has to be 6mm deep! if your stud protrudes 25 mm from the hub you will be fine… But if your stud protrudes 30 mm you have to do something! The spacer is only 25 mm thick! The reset of my wheels was between two and 3 mm (undefined casting )So I got it machines to have a total of 6 mm recess!

I do not think it will affect the handling negatively..

you essentially have wider track in the back, and the outside of the tire thread has minimal less weight on it because of negative camber… If that makes a difference is questionable…

you probably can adjust it if you change the camber by a1/3 of a degree (if this is even possible lol and i sucked the number out of my fingers)! in cornering, it might be more stable having a wider track… therefore more leverage onto the tire by 1 inch… Should be a wash…

but this is all guest work on my part..I’m sure some pros can pipe in on that! I am not racing the car… Just spirited driving!🤪

I don’t put spacers in the front!
