I'm converting my new (to me) GTS to 5 lugs, what were the OEM 5 lug wheel options?
Pics or part numbers if possible please.
Thanks

 

Having had both a CL and now 5-Lug 991.1 GTS, if you care about offset, flush look etc the 5-lug options are few and far between

Porsche decided to equip .1 GTS 5-Lug cars (from factory) with 20x8.5 (51 offset) and 20x11 (with 52 offset) wheels from the C4/C4S. Those wheels do not provide as flush and "complete" look on the 991.1 GTS as the CL wheels do from factory.
Center lock OEM wheels on .1 GTS are perfection as far as offset and flush-look.
If you are looking for something similar to the CL fitment, then your choices in OEM realm are 50th anniversary wheels from 50th Anniversary cars or the optional Club Sport wheels from the 991.1 Turbo 5-Lug optional equipment. (20x9,51 and 20x11.5, 56)
There are also "turbo fitment" 991.1 Turbo 5-lug wheels that have similar "flush" offsets to fit the wide body, even harder to find on preowned market.

Both can be found on the pre-owned market if you are patient or you can purchase from any online retailer like suncoastporsche

Another option, one I recently used after not having any luck finding pre-owned 50th Anniversary wheels, is replicas from companies like Augment wheels etc.

Hope this helps


(If you are wondering why the same 305 rear tire looks fine on the wider Centerlock wheel and Yet looks a bit stretched on "smaller" 11" wheel, its because the tire on the CL wheel was Porsche N0 spec (same Michelin 4S tire in same size) and is .7" wider at the same 305 size, the tire on 5-lug GTS is basic MP4S and clearly not as wide as the N0 spec 305

 

My 991.1 C2S with SPASM came with sport Classics and 5mm OEM spacers. Between the lower stance and the mild spacers the wheel to fender gap is perfect

 

OP's car is a GTS wide body, you are correct the narrow body wheels with 5mm spacers is pretty spot on (7mm and 12mm is usually preferred by flush look purists)

Wide body cars are lot wider than the measly offset change Porsche chooses for the Carrera 4/4S and GTS.

 

I'd suggest OEM SportTechno wheels, No need for spacers
