Weld Forged Drag Wheels for Camaro SS & ZL1: S71 vs S77

If you are shopping Weld forged drag wheels for a Camaro SS or ZL1, the decision almost always comes down to two faces from the same RT-S platform: the S71 and the S77. Both are 3-piece forged, welded-modular wheels built for the 2010–2018 Chevrolet Camaro SS and 2012–2018 ZL1, both share the 5x120mm bolt pattern, and both drop serious rotating mass versus a factory 20-inch cast wheel. The difference is mostly the face design, a fraction of a pound in weight, and how each one clears a big brake package. Below we break the two lines down side by side — sizing, weights, backspacing, fitment and pricing — so you can build a Camaro drag setup that hooks.

Weld S71 vs S77: What Is the Difference?

The Weld RT-S S71 and S77 are the same forged 3-piece drag-wheel platform wearing two different faces. The S71 runs a cleaner 7-spoke, moderate-concave design; the S77 uses a deeper-concave, more aggressive split-spoke look. Both are built the same way — a forged billet center welded to cold-forged aluminum rim shells — and both carry Weld’s “RT-S” (Road, Track, Street) intent: light enough for the strip, durable enough for the street. In matching sizes they land within about a pound of each other, so choosing between them is largely a styling and price call, not a performance one.

Every wheel here is finished in gloss black and uses Weld’s “High Pad” mounting-pad height, which offers three pad options across the range to clear the factory and aftermarket big brake kits found on the Camaro SS, 1LE and ZL1. These specific part numbers are the non-beadlock street-and-strip versions — no bolt-on beadlock ring — which keeps them street legal and easier to live with day to day.

Weld RT-S Camaro Wheel Comparison Chart

Here are the five most popular Weld RT-S fitments for the 2010–2018 Camaro SS and ZL1, compared by wheel size, backspacing, listed weight and price. Skinny 17x5 fronts and wide 17x10 rears build a classic drag stagger; the 18x8 sizes work as a lighter street-and-strip square-ish setup.

Why Forged Drag Wheels on a Camaro SS or ZL1?

A forged drag wheel improves acceleration by removing rotating and unsprung mass from the corners of the car. The factory Gen 6 Camaro SS and ZL1 ship on 20-inch cast wheels that weigh roughly 28–33 lb each; dropping to a 17- or 18-inch Weld RT-S forged wheel (about 22.5–28.5 lb here) trims weight where it matters most. Because that mass is spinning, every pound removed is worth more to acceleration than a pound removed from the body — the engine spends less energy spinning the wheel up and more energy driving the car forward.

Diameter matters too. Stepping down from a 20-inch to a 17- or 18-inch wheel opens up a much wider catalog of drag radials and slicks, lets you run more sidewall for a softer “launch” that plants the tire, and reduces the rotating diameter for quicker 60-foot times. On the front, a 17x5 or 18x5 “front runner” can shave several pounds off the nose to help weight transfer under a hard launch. That combination — light forged rears with a light narrow front — is exactly why Weld RT-S wheels are a staple on 6-second-to-11-second street cars.

Building Your Staggered Camaro Drag Setup

The classic Camaro strip stagger pairs a skinny front runner with a wide rear to maximize traction and weight transfer. Up front, a 17x5 or 18x5 wheel (about 22.5–25.3 lb) with a narrow front tire cuts steering effort and nose weight. Out back, a 17x10 wheel with 7.2 inches of backspacing swallows a 315-wide drag radial or a slick for maximum contact patch on launch. If you would rather keep the car looking factory-plus for street duty, a square-style 18x8 at all four corners is the cleanest, most tire-friendly option.

S71 vs S77: Which Should You Buy?

Choose the S71 if you want the lighter wheel and the cleaner, more classic drag look; in matching sizes it runs about half a pound to a full pound lighter than the S77. Choose the S77 if you want the deeper-concave, more aggressive face and do not mind the small weight penalty. Performance-wise they are effectively equal — same forged construction, same 5x120 fitment, same “High Pad” brake clearance — so this is a styling and availability decision more than a stopwatch one.

Fitment: Will These Fit My Camaro?

These Weld RT-S wheels fit the 2010–2018 Chevrolet Camaro SS and the 2012–2018 ZL1, which share a 5x120mm bolt pattern and 66.9mm hub bore (the same fitment also covers the 2009–2016 Cadillac CTS-V). The “High Pad” mounting-pad height is the key to clearing the larger Brembo brakes on the 1LE and ZL1; if you run an oversized aftermarket big brake kit, confirm caliper clearance before ordering. As always, our team in Tampa, FL can verify fitment for your exact year, trim and brake package before you buy.
