The 2023 Macan T is equipped with 350 mm diameter front rotors, the same as a Base 4 Cylinder Macan. Does anybody know if the 18” Porsche wheels will fit / clear the rotors? The Macan Base models prior to 2019 had smaller 345 mm rotors.

I already understand the other issues / pros and cons of 18” vs 19” and 20”.

Thank you!

 

I think Base Macans prior to 2021 had the smaller 245mm front rotors.
The 2021 Base got bigger rotors, a different front caliper, and the V6 version of the uprights/hub-carrier which the calipers bolt onto.

 

I just installed 345 mm rotors on the front of our 2018 Macan 2.0 Base and I believe the T version of the Base uses 350 mm rotors up front with the same 330 mm in the rear on all variants. I'd speculate the 18's will fit.

 

Thank you!

 

Yeah I'm not sure about that. From the Porsche Tequipment site there are only 19" and 20" winter wheel options for the 95B.3 Macan base model. I'd probably ask your dealer's service/parts department to confirm before you pull the trigger on a set 18s that don't fit.

 

Does anybody know if there is an issue with clearance for the suspension components with the smaller 18 inch? Thank you!

 

Have you tried asking your dealer's service or parts department? They will know for sure.

 

You can try this website:
https://www.wheel-size.com/size/porsche/macan/2023/
They list all the possible wheel fitments for the Macan 2023 T. They say an 8Jx18 ET 21 and 9Jx18 ET21 will fit. Whereas for the S and GTS only 19" and 20" will fit respectively. This site also has a drawing of the suspension dimensions but I cannot find how to access it now. Used it when I spec'd HRE wheels for the GTS as HRE uses a 1/2" wider rear wheel than OEM and I wanted to check clearances.

Found the drawings. At the far right of the table select the Icon for "Tire calculator comparison". Select the OEM fitment for reference then the next listing down which is the 18". Click on the small box with the arrow and it will show your fitment. You can add different size tire fitments if you want to check clearnces and I think you can change wheel offsets as well.

Thank you all for your help. I decided to order 19” setup today to ensure that they fit my current Macan T and also in case I decide to upgrade to a Macan S in the future.
