Description

The 992 GT3 RS is already one of Porsche’s most advanced track weapons, but the factory suspension has compromises. The OE progressive springs, rated at 140–160 N/mm front and 182–215 N/mm rear, balance comfort, compliance, and performance. In contrast, the 992 GT3 Cup runs 260 N/mm front and 300 N/mm rear to keep the chassis locked under extreme grip. SP Motorsports’ upgraded spring package sits between the two, with 166 N/mm front and 211 N/mm rear. This setup delivers strong track control while remaining manageable for dedicated street driving.
