Default Wheel specs

My 2002 is finally coming home from the shop after new clutch, gearbox rebuild, LSD add & engine out service. Time to replace the outdated 19" wheels from the PO. Want to go to 18" that fill the arches without rolling or aggressive camber settings. Any suggestions?. Not interested in twists, or cast wheels. Car has been converted to 2wd and lowered on coilovers.

Need to know the original wheel sizes (including offset) to get started shopping.
Thanks!

I wouldn't run OEM sizes with the addition of an LSD on a RWD converted and lowered car. I'd start with GT2 sizing. You might want to rethink not rolling the rears to accomodate wider wheels and a lowered stance. If you drive aggressively in off camber situations there will be some rub if you don't make some minor adjustments fo wider wheels. Same with "settings" for a lowered car. The potential for premature tire wear always exists with "stock" alignment settings. Usually "toe" less so "camber". Everything is a "trade-off".

I believe these numbers are correct. Internet search yields:

F 18x8 ET50 225/40R18
R 18x11 ET45 295/30R18

18x8 50 225/40R18
18x10 47
Porsche Winter use

GT2
F. 18x8.5" ET42
R. 18x12" ET45

I was looking at some SM 10's ( again ) by APEX which are a decent and comparable alternative to my old OZ and remembered also to mention one other combination I have run many years ago that sat perfectly with a ( then ) 1" drop. 7 X 15 spacers with stock 996 TT wheel offsets.

You might also find this guide of possible combinations available helpful.

My CCW front wheels are a littler wider than stock and have slightly different offsets but fit fine.

I tried searching to find these exact specs but couldn't track them down. Hoping he chimes in so I can save for potential future use : )

No, just a personal type of hobby as I have access to both a team of engineers, as well as manufacturing facilities.

PM me and we can set up a call if you'd like.

Cheers,

There are many ways that I build these. It depends on each individual application, if using 350 or 380 brakes, tire selection, etc. 18x9x12 ET 42 is a straight forward direct bolt on for 996GT2 tire sizing.
