Hartge classics in 19"

[AGT1953]

Hi,
Will these fit my 1998 Z3M Roadster without any issues:-
"Set of genuine Hartge classics in 19"
Satggered set up 8J fronts and 9J rears Made in Germany by Ronal for Hartge
5 x 120 PCD
ET40
Taken from a E39 5 series BMW"

Thanks,

Andy, Glasgow.

Just run the sizes through the offset calculator which shows you the difference the wheel will sit in the arches. Fronts may be ok, but the rears look cozy. Obviously with the rim being a 19, you are going to lose a bit more space as well.

Not sure if someone like @Lee or @Aceman can confirm my guesswork or not...

Front wheel change:

Rear wheel change:

They will fit, but you will need spigot rings as the bore will be bigger.

Hi,
Thanks for your postings.
OK, what are spigot rings??

Good call, I knew that but temporarily forgot...

The Z3 has a different size hole in the centre of the wheels to the E39 5 Series, so you need a small adapter to make them line up nicely on the hub.

5 Series E39 = PCD 5x120, centre bore 74.1mm
Z3 E36 = PCD 5x120, centre bore 72.5mm

Hi,
Many thanks for your posts.
So if I were to buy these what size tyres would need to be fitted to keep the rolling circumference the same as my existing 17" wheels??
This is a real pain as I have just fitted new PS3's to them!!

Thanks,

Andy.

If you have 225 45 17 i believe you will need 245 30 19 giving you 69.48 mph instead of 70mph or you can go 255/30/19 to get 70.14mph

Also the rears from @GazHyde calculator are 39mm closer to the rear shock and 27mm further in from the wing edge so you will need 25mm minimum spacers.to push the wheel out.
