Today I changed the 18 858 Mwheels on my I4 e40 msport with gmp Specternblack diamond 19 inch .Gmp is an italian wheel maker,they have olso the new model Luminca on listed their website S compatibile with the i4

Michelin pilot sport 4 with star marking for Bmw fuel efficiency A graded.
245 40 19 front
2455 40 19 back

Wheels are very light similar to 859 M 11.5 kg and ea h wheel can be loaded 800kg front 825 back.Saw these wheels on the web mounted some Tesla model Y and X .

These look great! I checked the GMP website and according to them the 19" are only available in 8" and 9" widths. Are these 8" front and 9" rear? The Fondmetals I've ordered come in the same widths, and I was worried the front would look recessed compared to the stock width of 8.5", but on your car these GMPs look mint!

Hello,

Yes the are 8 în front but the et is 30 instead of 36 like the OEM so the 0.5 inch is compensated by the difference in et(0.6)

Would be interesting to know the weight of the different wheels people run, (Rim + Rubber), i just got my Style 826M and when changing i will weight the 858M 18''

My Style 826M 20 is really heavy so im hoping they will not ruin the performance of the car.
Will do a performance test with acceleration 0-100 and 100-150 on both sets and get back with results.

This is with winter friction tyres.

8.5X20 ET25 245/35-20 front = 54,2lbs/24,6KG
9.5X20 ET38 255/35-20 rear = 55,7lbs/25,3KG

Hello ,very good idea.I am olso curios on how much the range will be affected.
I am sorry I didn’t weight the 18 inch 858 M with the Hankook tires when I changed them with the 19 inch aftermarket Gmp Specter.
I will weight the Specter when a will swap them for my 18 inch 853 with the Pirelli winter tires.
After I changed my wheels, and changed the settings in the idreve from 18 to 19 I suspect my GOM now shows less range .With the 19 charged at 80% shows 340 km max. But with the 18 inch was about 390 max.

Thats great would love to know the weight of the GPM Specters.

I'm hoping to find time to change to my new wheels this weekend and will weight the 858M when they are off the car.

Did you notice any difference in the acceleration och power when you changed from 18 to 19?

The gmp Specter without the tires are at 11.5 kg.I will weight them with the tires when I swap .

Acceleration is the same.No decrease on power.Even consumption is the same. aprox 17 kwh in the city.Only the projected range(GOM) is less 10% aprox...

Hey, im thinking of buying the GMP Specter as summer wheels, but are you sure they weigh 11.5KG? All websites i can find states they are about 16kg which sounds really heavy.

Check this as an example: GMP Specter black diamond | ✪ felgenoutlet.com

Hello again I don't know exactly where I saw it all I can find write know is from the technical data sheet from Gmp website it says 14.9 kg.

Yesterday i put my new summerwheels on.
Hard to get a good picture with dark wheels and low light but in really happy with the result.

they weight exactly the same as stock 858M in the rear, and are even lighter in the front.
