Wheel experts help me out! Trying to confirm these front wheel fitments will work on a 991 GTS with center lock wheels... according to willtheyfit.com this is only pushing the front wheels out by 4mm which seems fine given they are already a wee bit tucked in as is. That said I'm trying to find some comparables or someone that has put new CL wheels on a GTS but info is few and far between. Any input or advice is appreciated.

GTS wheels:
Front - 9.0J x 20 ET51

New wheels:
Front - 9 x 20 ET47

 

Considering that Porsche offers a 5mm spacer kit, these would be fine.

Unfortunately the 5mm spacer is for the non-GTS cars with a 20x8.5" wheel and different offsets so not really apples to apples.

What I'm still trying to find out is if someone is running anything more aggressive than 20x9 +51 up front on a 991 GTS... I have the option of going anywhere from +52 to +47 and may just end up in the middle somewhere.

Anyone?

 

I still think you will be fine. Porsche is still pretty conservative when it comes to its offsets. Remember we are talking about 4mm, that is less than .25".
