Best Rear Camber Kits for 2004-2008 Acura TSX & Accord

If you have lowered a 2003–2007 Honda Accord or a 2004–2008 Acura TSX, the rear tires are almost certainly wearing on their inner edges — and a rear camber kit is the correct fix. Dropping these cars on springs or coilovers pulls the top of each rear wheel inward, adding negative camber that the factory suspension has no built-in way to dial back out. The best answer for the 7th-generation Accord (CM chassis) and the first-generation TSX (CL9 chassis) is a set of SPC Performance rear adjustable arms, priced from $85.77 for a single link up to $514.24 for the complete five-arm set. This guide compares all five SPC options, explains exactly what each arm corrects, and shows you how to pick the right one for a street car or a track build.

Why does a lowered Accord or TSX get negative rear camber?

Lowering a 7th-gen Accord or CL9 TSX adds negative rear camber because the rear multi-link geometry swings the wheel inward as the suspension compresses. The factory rear camber spec on these cars is roughly –1.0°, and a typical 1.5–2 inch drop can push static rear camber to –2.5° or worse. That angle tips the tire so it no longer sits flat on the road, concentrating the car's weight on the inner shoulder of the tread.

The result is fast, uneven inner-edge wear. At –2.5° of rear camber, an aggressive 200–300 treadwear tire can burn through its inner shoulder in as little as 5,000–8,000 miles while the outer two-thirds of the tread still looks new. Excess camber also reduces the contact patch under braking and steady-state cornering, so the car actually has less mechanical grip than a properly aligned setup — a common surprise for owners who lowered the car chasing better handling.

There is a second, less obvious problem. Honda's rear suspension on these chassis is a true multi-link, and the arms interact with one another. If you change the length of just one arm to correct camber, you can bind the system and throw off toe and set-back at the same time. SPC engineers its rear links as a matched family specifically so you can dial camber, toe, and set-back together and take the bind back out. That is why a purpose-built rear camber kit — not a generic bolt — is the right tool for this platform.

What to look for in a rear camber kit for the Accord and TSX

The best rear camber kit for a 2003–2008 Accord or TSX gives you enough adjustment range to reach factory spec, uses joints that survive daily driving, and does not bind the multi-link. Here is what matters when you choose between a single arm and a full set:

Adjustment range and what the arm corrects

Match the arm to the alignment number you are chasing. A camber-only fix (inner-edge tire wear) needs an adjustable upper link. A track alignment that also targets toe and rear caster/set-back needs the matched lower and upper set-back arms so the geometry stays neutral. SPC's arms restore alignment back to factory spec and add extra range for aggressive track settings.

Joint type and ride quality

On a street car, ride quality is decided by the bushings. The SPC lower set-back arm (part 67292) uses bonded rubber bushings to keep factory-level noise, vibration, and harshness, while the EZ Arm XR (part 67290) integrates an OE-style ball joint so it behaves like the stock arm it replaces. That is the difference between a kit you notice only at alignment time and one that adds cabin noise.

Install effort and warranty

Every SPC arm here is a bolt-in replacement — no cutting, no welding — and each is backed by SPC's limited lifetime warranty. Budget roughly 2–3 hours per axle with hand tools, plus a professional 4-wheel alignment afterward. At our Tampa, FL shop we always finish an adjustable-arm install on the alignment rack, because the arms only pay off once they are set to a target number.

SPC rear alignment arms compared: which one do you need?

All five arms below fit the 2003–2007 Honda Accord and 2004–2008 Acura TSX (the EZ Arm XR also covers 2003–2008 Accord). The complete Set of 5 combines the individual links into one full rear-alignment solution; buying the four individual arms listed here already totals $428.87, so the set is the value play once you need more than one correction. Prices and part numbers are current at NLP Performance.

1. SPC Rear Adjustable Arms, Set of 5 — Best Overall

The SPC Performance Honda/Acura Rear Adjustable Arms (Set of 5) is our top pick because it is the most complete rear-alignment solution for the platform. This five-link set lets you adjust camber, toe, set-back, and track width on the Accord, TSX, and many other Honda and Acura models, and because the arms are engineered to work together, you can chase an aggressive alignment without binding Honda's multi-link. Whether you are correcting angles after a ride-height change or building a dedicated track alignment, this is the kit that covers every rear adjustment in one box.

2. SPC Rear EZ Arm XR — Best Single Arm for Camber

If your only complaint is inner-edge tire wear, the SPC Rear EZ Arm XR Adjustable Control Arm (part 67290, $119.10) is the smart, targeted fix. It replaces the factory rear arm with an adjustable version that integrates an OE-style ball joint, so it works at stock height or lowered and keeps the suspension feeling factory. SPC notes these rear arms suit Accords, Pilots, and more, and they are the go-to for owners who want to reset rear camber without buying the full set. Pair it with a good alignment and your rear tires will finally wear flat.

3. SPC Lower Camber Lateral Link — Best Value

At $85.77, the SPC Lower Camber Lateral Link (part 67291) is the lowest-cost way into SPC's rear system. This forged arm affects set-back, camber, and track width, and it ties into the knuckle directly below the EZ Arm XR (67290). Adjusting this link in unison with the upper arm is exactly how you take the bind out of the multi-link while you set camber — which is why enthusiasts building toward the full set usually add this arm first. On its own it is a budget-friendly camber correction; combined with 67290 it becomes a proper two-arm camber solution.

4. SPC Lower Set-back Control Arm — Best for Daily Comfort

The SPC Lower Set-back Control Arm (part 67292, $114.99) is the arm to choose when quiet daily driving matters. It adjusts set-back and toe, and unlike a spherical-joint race arm, it uses bonded rubber bushings to maintain factory levels of noise, vibration, and harshness. That means you can correct rear toe on a lowered street car without adding the drone or harshness that comes with solid bearings. It is a natural companion to the camber arms above when you want a complete, comfortable alignment.

5. SPC Upper Set-back Control Arm — Best for Track Alignments

Serious track alignments need clean set-back and track-width control, and that is the job of the SPC Upper Set-back Control Arm (part 67293, $109.01). This forged upper link adjusts set-back and track width, and its adjustability lets you remove bind as you dial camber with the other arms. Run it alongside the lower links and you can build a neutral, repeatable rear alignment that holds up to hard cornering. For a street car it is optional; for a track build it is the arm that keeps the whole multi-link honest.

How to install and align SPC rear arms on your Accord or TSX

Installing SPC rear arms on a 2003–2008 Accord or TSX is a bolt-in job that most DIYers finish in 2–3 hours per axle. Safely lift and support the rear on jack stands, remove the wheel, and unbolt the factory link at the knuckle and subframe. Set each SPC arm to the same measured length as the factory part it replaces so the car is drivable, torque the hardware to the OE spec, and reinstall the wheel. Do not try to eyeball final camber by adjusting a single arm — that is what binds Honda's multi-link.

Then align it. A professional 4-wheel alignment is mandatory after any adjustable-arm install. For a street car, target roughly –0.5° to –1.0° of rear camber with rear toe near zero for even tire wear and stable highway manners. For a track alignment, more negative camber can help mid-corner grip, but keep an eye on braking stability. If you also want to correct front camber on a TSX, the Skunk2 Pro Series front camber kit pairs well with these rear arms.
