De G-model en 964 flaporen zijn alleen qua uiterlijk hetzelfde ...

Buiten het uiterlijk zijn er dan meer aandachtspunten waar ik rekening mee moet houden?

Da's waar, maar hij is ook met flaporen en (optionele) cup1 de fabriek uitgerold

cupvelgen waren een optie in vanaf modeljaar 1991, design 90 was standaard toen. cup 1 velgen van modeljaar 1992 standaard, icm cupspiegels.

The standard wheel size diameter for the 964 series of narrow body versions was 16-inches. 17-inch wheels were never offered on model year 1989, 1990 and 1991 normally aspirated 964 versions, they were offered only for the 911 (964) Turbo.
New 10 mm steering stops (replacing the 6 mm versions) were installed at the start of the 1992 model year. 17-inch wheels were approved for retrofitting on earlier models as long as new steering stops were installed and a minor body structural modification was
carried out. Later limited editions of the 964 series were delivered with 17-inch wheels as standard. The only models to receive 18 inch wheels were the Turbo S, the Turbo 3.6, Turbo 3.6 S and the RS/RSR 3.8 series.. 18-inch wheels were never offered as options on any other 964 and are not approved for installation on any other 964. The original factory wheel sizes were 6JX16 on the front and 8JX16 on the rear. The original standard tyres were 205/55ZR16s on the front and 225/50ZR16s on the rear. In Europe the “standard tyre” manufacturer was Bridgestone with type RE71s. The RE71 was not the standard tyre for the US versions of the 964. Research has shown that other tyre manufacturer products were installed as well for the US versions. Option M231 authorised this. This was not a customer offered option either. It was reserved for internal factory requirements.
The original wheels for the 964 were the Design 90s. Which turned out to be the lightest wheels fitted to the 964. They might not look pretty to some but they are still the best and most cost efficient wheels for the club sports racer.
In 1992, the Design 90 wheel was replaced by five spoke cast aluminium Cup design 92 wheels. These were made available in 16” and 17” sizes with widths from 7” to 9”.
Wheel specifications for the Carrera 4 and Carrera 2 models were same.
Note: There are subtle differences between actual wheel design in the Design 92 series for the 964 NA series, 964 Turbo and 968.

Brrrr, wat een vieze mannetjes hier

Heb zelf nog de cupspiegels gemonteerd op mijn 964 met 17 inch cup wielen, vond dit zooooo mooi
Wat ik achteraf jammer vond is dat ik hem niet wat heb laten zakken, staat zo stoer
En ja hoe zeggen ze dat ook weer in het Engels, "uiteindelijk" had hem moeten houden, was zo'n fraaie auto

Ja, inderdaad zonde dat je die hebt weggedaan. Bijna medelijden met je om de 2 P's waarin je je nu moet verplaatsen... (geintje)
