FAQ
Is the F321 fully forged?
Yes. The F321 is a one piece monoblock wheel. The entire wheel is machined from a single forged 6061 T6 aluminum block. A flow forged wheel, by contrast, has a cast center with a pressure formed barrel.
How much does the F321 cost?
From $1,100 per wheel in 18 inch to $1,500 per wheel in 22 inch. Brushed Clear adds $150 per wheel. Choose quantity 4 for a full set.
How long does it take to build the F321?
Build time is 8 to 10 weeks. Every F321 is made to order for your vehicle, and production starts once we confirm your full specification with you.
What widths and offsets are available?
Width and offset depend on the diameter and your vehicle. See our monoblock forged size and offset chart, or contact us with your year, make and model and we will recommend the right specification.
Will the F321 fit my car?
Each set is built to your bolt pattern and offset. Contact us with your year, make and model and we will confirm hub size and brake clearance before production.
What is the warranty and return policy?
One year from the date of purchase against defects in materials and workmanship. Full custom forged orders are final sale. Full terms are on our warranty page.
