Circuit Performance CP37 Wheels offer an RPF01 style split-spoke with a stepped lip design. This wheel design is popular because the thin spoke design allows the wheel to be ultra lightweight while still being extremely strong.
The Circuit Performance CP37 has styling similar to RPF1 rims, a design that is celebrated for its simplicity and minimalist racing styling. The spokes on this partilar size are flat, and merge elegantly into the lip of the wheel. In the middle of the wheel you’ll find a circular lug pocket, with only 4 lug holes and a flat Circuit Performance logo center cap.
This wheel is a single-drilled 4 Lug, so it will only fit vehicles with a 4×100 bolt pattern. It’s 15×7 which means it has a 15″ diameter and an 7″ width. The offset is +28mm which means the mounting pad is 28mm forward of the centerline of the wheel. The centerbore in the back of the wheel is 73.1mm, so it can easily be hub centric to any vehicle by using a hub centric ring during installation. It is a great size for most 4×100 vehicles because it has outstanding caliper clearance, and there’s fery few 4×100 cars this won’t look great on.
This wheel features a flat bronze finish with a matte clear coat. The 1.9″ stepped lip is also painted bronze and clear-coated for protection. A black Circuit Performance center cap with silver logo blends nicely in the center of the wheel.
This wheel design is fantastic for its simplicity and lightweight characteristics. It weighs in at 15 lbs, on the dot including center cap, making it a great choice for someone concerned about minimizing unsprung wheel weight while staying on budget. You’ll find examples of similar twin-spoke design wheels used on open-wheel F1 cars, time attack champions, and rally cars. It’s certainly not the flashiest wheel around, but it offers great bang for your buck and should be a top choice for many performance builds.
This wheel is ideal for 4×100 Honda Civic (EF/EG/EK/EP), Acura Integra (DA/DC2), Mazda Miata (NA/NB), BMW (2002/E30), and Mini Cooper.
