APEX ARC-8R DESIGN
10K TONS OF PRESSURE
To make these the strongest wheels they possibly could, APEX applied as much pressure as possible using a 10,000 ton forge. This extreme pressure increases the strength of the aluminum by eliminating porosity and improving the grain structure.
Many companies use 3rd-party blanks intended for non-motorsport wheels which can severely limit sizes, concavity, spoke design, and critical brake clearance. APEX invested in their own proprietary blank profiles to give them full control over the final product.
Want to know how strong a wheel is? Look at the load rating. Many wheel manufacturers simply rely on the word forged to imply strength, when their actual load ratings are just as low as cast wheels. APEX forged wheels were designed from the start to have measurably higher load ratings so they don’t just sound stronger, they are stronger.
BIG BRAKE CLEARANCE
The ARC-8R addresses the biggest challenge faced with the original flow-formed ARC-8: brake clearance. Thanks to new high-clearance forging blanks, 380mm brakes now fit behind the 18” version with plenty of breathing room.
BIGGER, TOUGHER INNER LIP
The inner lip is the most vulnerable part of a wheel, because it has no spokes for support. By using forged 6061-T6 aluminum, and reinforcing this high-impact area with more material, APEX provide an extra layer of protection against track berms, potholes, and whatever else the road may throw at you.
APEX conducted extensive Finite Element Analysis (FEA) to reinforce high stress areas and to remove material where it didn’t improve strength. The end result is a wheel with an ideal balance of strength and weight.
PAINTLESS KNURLED BEADS
Whether it’s a day at the track or months of street driving, repeated hard braking can make a tyre slip along the bead seat and go out of balance, causing vibration. Knurled beads help, but are less effective when painted over. APEX Forged line wheels feature unpainted knurled beads that stay sharp and maximize grip.
BUILT FOR IMPACT SOCKETS
Track wheels need track tools. Don’t settle for wheels that require undersized tuner lugs or thin walled sockets. All APEX wheels accommodate over-sized race lugs and impact sockets to make swapping wheels lightning fast.
The forged line wheel has enabled APEX to release the finishes they’ve always hoped for. Fully polished aluminum, hand brushed with tinted clear, and a much wider range of painted finishes. APEX forged wheels not only deliver performance, but also distinctive new styles as well.
JWL AND BEYOND
APEX forged wheels exceed JWL load rating requirements by almost 20%. Some manufacturers don't meet the minimum requirements, yet still claim to be compliant. Always compare load ratings to ensure you aren’t sacrificing critical strength for a slightly lighter wheel.
The VIA is an independent wheel testing and auditing agency similar to TÜV. Many companies falsely claim their wheels have been certified, and even use the VIA stamp without permission. APEX wheels have been certified, and they provide the registration numbers for every wheel. Protect yourself. Demand registration numbers from manufacturers.

Touched base with Sean to do some coding work on my F85 X5M. Not only was he a whiz with the tech stuff, knowing his way around without any difficulty. Very rare to find someone like Sean - I happily rate and recommend this business for anyone.
Seriously great service and people. Honest and fair. Would happily recommend anyone to them.
The guys are great, definitely take your BMW there.
Fantastic customer service from the team at Southern BM. Expertly repaired my 2011 323i and did so without the attitude and excessive cost of a dealer. Thank you and I will be back for all future servicing.
Had the rod bearings on my E92 M3 replaced by SouthernBM, very happy with service and price, highly recommended. Many thanks!
