Forgot your going wider in the rear... On re-think, I think Izzone is on the money 100%... Gt3 fronts, RS rears... Just do a test fit with wheels of someone's car or ask dealer to slap on some GT3, RS wheels to confirm and you should be good.

Dispite the wider front, you don't have the stick on fender parts and thus RS wheels will extend way beyond your fenders....

After looking at PET (spindles, hubs Cl nuts are the same thing on GTS and GT3RS) from my dealer and talking to wheel people and knowledgable Porsche techs all I need is GT3RS/Turbo rears 12x19 et48 rears and GT3/Carrera fronts 9x19 et51 or 8.5x19 et 53....right around those offsets but yes a 47or48 offset that is on a GT3RS will cause the wheels to stick out, thus why the RS has the stick on fender arches. Suspension geometery is the same in these cars but Porsche makes a wider track by the offset in the front for the RS.

Carrera GT

Why not get the fender extensions, roll the fender lip to make some space and go with the GT3 RS geometry? (and get the solid toe arms front and rear ... probably stiffer anti-roll bars and semi-solid engine mounts, then you've got a PDK GT3.)

Hey you...STOP spending my money and putting pornographic thoughts into my head!

Dang you...you think just like me and are spilling my plans down the short road to have a great cheater DE car.

Please give me a call. I'd be glad to help.

Thanks Damon we talked yesterday...remember??? Music Industry

Izzone is correct and just what you suggested too...GT3 fronts with GT3RS rears.

Now I either need to wait until there is a sale to help on the pricing for the OZ Forged Super's or what I call...cheese out...and get the cast OZ for $3k less

I just bought the Precision Insturments torque wrench and the truck brake pedal depressor from tooltopia.com that Trakcar told me about.

Yeah Izzone is correct and this was verified by Damon at Tire Rack...for the GTS and/or Turbo I need Gt3 front offset and RS rear offset

Shameless plug here,

I have a set of 18 gmg wheels for sale from my RS. Posted here under parts for sale.

Mike, I bet they fit. Randy has the same, I know offset might be slightly diffrent in front, but even in MKI 255 easily fit. We have a lot of room in front left. If they don't sell the fronts!

mdrums

If I new that the fronts did not stick way out I would get these for sure but I've seen 9" wide at et51 offset and it is perfect and I really believe that the et48 on a 9" wide wheel will stick out past the fender.....thus the flairs you have on the RS.

You should scoop these up for an extra set since you bent some E88's. the Red would look cool on your car for sure!

Tempting, but now I have all matching..

Mike, that is only 3mm sticking more to the ouside right?!
We have way more margin than that?

mdrums

stock offset is 53.....OZ for example is 51....these are listed at 46.

That is 7mm over stock and 5mm over the pushed out to the edge OZ.

Although I am really confused about offsets....smaller number the more pushed out the wheel is....Forgeline quoted me some really really odd offsets...compared to stock offsets and what Tire Rack shows for th OZ offsets with all make sense.

Forgeline

I just want to clear up some information on what offsets Forgeline builds in Porsche Centerlock fitments. Our standard fitments are below. Of course we could always make a custom offset if needed, however it would take a couple weeks longer than our standard 2-3 week build time to complete. Let me know if you have any questions regarding these fitments, I would glad to help with whatever you need.

In my opinion the 9 at +46 on the front of a GT3 or GTS will be quite aggressive unless you have 2 or 3 degrees of camber dialed into it.
