BBS RT88 specifications for Porsche 991 GT3
| Position | BBS reference | Item number | Size | Offset | Connection |
|---|---|---|---|---|---|

The technical layout of the RT88 is deliberately traditional BBS: a forged motorsport center, a separate forged LM rim and a two-piece assembly. The center traces back to the E88, while the rim uses established BBS Japan LM technology.
Finish options for Porsche 991 GT3
Two LM rim finishes define the final look: SLD Silver Diamond and BKBD Black Diamond. Both can be paired with any of the six center colours shown in the product options.
