Anyone know what the rims widths and offsets are? Do the rears also use 5 mm spacers?

 

Here you go

Front:
8.5 J x 19 RO 53
P/N 997.362.156.95 (silver) or 997.362.156.96 FFF (041 Black /8C6 Orange)

Rear
12 J x 19 RO 51
P/N 997.362.164.91 (silver) or 997.362.164.92 FFF (041 Black /8C6 Orange)

I can't answer the spacer question it would depend on the car

 

Thank you.

 

hey cnc:

Sorry for the newb question but are those specs the same for RS and regular GT3?


thanks

No...the GT3 is narrow body whereas the RS is widebody so thus as a result the rear offset is different. I originally had GT3 wheels on my 997TT and had to use 18mm spacers in the rear to compensate. I've since then switched to the RS wheels without the use of any spacers.

 

The RS is a C4S body and has a greater 44 mm track than the GT3. Therefore the RS offsets in the rear are different than the GT3.

 

The GT3 RS comes with an O.E. 5mm spacer at the rear wheels.

 

Does the GT3 use a rear 5mm spacer?

 

I know my GT3 came w/ a 5 mm spacer in the rear. I am still running it. I put the Dymags right over them and the fit and wheel/tire position in the fender is perfect.

 

another newbie qustion but.. i thought both the GT3 and the RS used the idential rear wheel and tire size. the only difference was the RS has a rear spacer.

 

Both use 5mm spacers, plus the RS offsets are 17 mm less than the GT3. Wheel and tire sizes are the same.

 

GT3 = narrow body (C2)
GT3RS = wide body (C4, TT)
Front wheels are the same
Rear wheels have different offsets

 

porsche states that the tires size are both 305/30/19. but they also say that there are GT3 wheels (gt3) and lightweight GT3 wheels (RS). i think gt3ranger is correct since he does own both the Gt3 and the RS

 

The GT3 and GT3RS wheels are eaxctly the same except for a different offset on the rear wheels - no difference in weight.

 

jhbrennan is correct. I had both versions. Originally I got the GT3 wheels and used 18mm spacers with my 997TT. I sold my rear GT3 wheels and got the GT3 RS wheels instead so that I wouldn't have to use any spacers.
