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.
PRORIETARY BLANKS
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.
FEATURES
ACTUALLY STRONGER
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.
WEIGHT OPTIMIZED
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.
PREMIUM FINISHES
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.
TRUE VIA
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.

My first dealing with Southern BM was a pleasant one. I had some springs and shocks installed and Sean was a delight to deal with. Knowledgeable, helpful and offered solutions when not everything went to plan. I would happily recommend them.

After 3 other BMW workshops couldn't fix the problem with my M3. SouthernBM sorted it. Excellent to deal with, great communication and customer service.

Sean arranged a Quaife LSD for my 135i and I couldn't be happier. He advised multiple seals and bearings needed replacing unbeknownst to me so these were done as well. Now I have a more reliable car and one with tonnes more mechanical grip!

I have used many mechanics over the years for the many different types of vehicles in our company fleet and southern BM is one of the very few workshops I can highly recommend. Andrew and his team are also really passionate about their work and it shows.
