Frequently Asked Questions (FAQ)
Q: What is the optimal staggered restomod fitment for a 1987 Buick Grand National?
A: The most popular setup is 18×8.5J front (zero offset or ET+6 with 245/40 R18) paired with 18×9.5J or 18×10.0J rear (ET0 to ET+12 with 275/35 R18 or 275/40 R18 tires), achieving a deep dish stance without rubbing factory inner wheelhouses.
Q: Will these wheels clear aftermarket Wilwood or Baer disc brake conversions?
A: Yes. The 3D drop-center stepped barrel and recessed spoke pocket design provide generous clearance for 4-piston and 6-piston aftermarket big brake upgrades commonly installed during G-body restomods.
Q: Can these wheels be machined in GM 5×4.75″ bolt pattern?
A: Yes, we precision CNC-machine exact GM 5×4.75 inch (5×120.65mm) bolt circles and 70.3mm center bores for a 100% direct hub-centric fitment with no wobble or adapter rings needed.
Q: What load ratings and safety standards do these wheels comply with?
A: All sets meet or exceed JWL and VIA standards, SAE J2530, and DOT regulations with heavy dynamic load ratings exceeding 850kg per wheel.
