I've asked my service dept about fitment of GT3 wheels and they keep telling me that they do not know but will look into it. Suncoast sells GT3RS wheels/tires but will not tell me if they will work properly on a 991 TTS. Guess both are freaked about legal liability and potential PCNA blowback. I would like to stay with Porsche wheels .

 

The Turbo S comes stock with a staggered wheel setup...

I don't like aftermarket wheels. I personally like the OEM look and prefer the OEM GT3 wheel design to any wheel on the market.

 

The difference between rolling diameters on the GT3RS with the 20/21 would probably detonate the AWD transfer case. Vendors have looked for front tire solutions to balance it out and havent found any. I'm under the impression (but dont know for a fact) that the GT3 wheels allow tires that are more in line with the 27.1"/27.4" F-R difference that comes stock.

 

Staggered offset and width, not diameter. Both F/R on a TT, TTs, GT3, GTS, whatever, are all 20".

 

I certainly would not guess about anything that would damage the car. Will keep it stock, although do like the GT3 wheels if they will not compromise any systems.

 

I agree with AndrewP, i wouldn't want anything that will damage the car or its function. If i can make the stock tires fit on the GT3 wheels, will that work?

PS thank you for your reply and great input, it's much appreciated.

Gotcha. Should i do 26' Asanti's?

 

Amir just buy a set of wheels already or Ill send your Instagram stalker to your house

LOL

 

DUDE NO! WHO IS THAT GUY

PS i'm trying, i just want the GT3 wheels -_______-

 

You could always opt for ADV.1's private design program and create it yourself. It would be lighter, stronger, and better

 

I definitely don't want aftermarket, i like the OEM look. But if i do go aftermarket i wouldn't get ADV.1's. BBS/VOLK>

 

A turbo S rim looks terrible on a GT3, just my opinion. I love my 991-GT3 and cant see it any other way than bone stock- except for exhaust mods, GT3 for life, god dam i love my car. It hits all the senses and some i didn't know i had!! Porsche!!!!!!!

 

The 27.1/27.4 you're getting is the F-R for a GT3RS?

Because the GT3 and Turbo S both have a 27.2"/26.75" F-R differences stock. They both run a 245/35/20F & 305/30/20R P-Zero.

Based on my calculations, there should be no problem with the AWD transfer case as the rolling diameter and the tires size are exact for the GT3 and Turbo S, the GT3 just has wider tires (.5 inch) and a more aggressive offset. Correct?

 

Off Topic but i wish the Venders who are reading this and PMing me to try to sell my aftermarket wheels would instead try to HELP the ones who aren't interested in an aftermarket wheel get the wheels we want. Trust me when i say this, we already know that BBS/HRE etc are lighter than stock. By helping you would get a lot more business than trying to pitch me in a PM on some HRE's you have in stock SMH.

 

All i know is my rims and tires are the pinnacle!!! Tenacious grip!! That .5 makes a difference
