Eibach Rear Camber Kit for 04-08 TSX/03-07 Accord

Eibach Pro-Alignment Rear Camber Kit - TSX/7th Gen Accord

You lowered your TSX or 7th gen Accord and now you're eating through the inside edge of your rear tires every 15,000 miles. You go to get an alignment and the shop tells you there's no rear camber adjustment from the factory. You're sitting at -2.5 degrees of negative camber and there's nothing they can do about it. Honda didn't give you any way to adjust camber in the rear. You can adjust toe with the cam bolts, but camber? You get whatever the suspension geometry gives you and that's it. At stock height that's usually -0.75 to -1.0 degrees and it's fine. Lower the car 1.5 inches and you're looking at -2.3 to -2.7 degrees. That's way too much negative camber for a street car. The inside of your rear tires is getting destroyed and there's no factory fix. Eibach's Pro-Alignment kit replaces both upper rear control arms with adjustable arms that give you +4.0 to -2.0 degrees of adjustment range. Now you can dial your camber back to -1.0 or -1.5 degrees for even tire wear or you can run it more aggressive if you're tracking the car. This is a complete kit with two arms. You're getting both sides. Part number 5.67290K.

Here's Why the Factory Setup's a Problem

The 1st gen TSX and 7th gen Accord have zero rear camber adjustment from the factory. None. The only thing you can adjust in the rear is toe and that's done with a cam bolt that loves to seize solid after a few years of salt and road grime. Stock camber's around -0.5 to -1.5 degrees depending on how the car sits and that's fine for a stock-height car. Lower the car and the camber goes way negative. We're not talking about a little bit negative. We're talking -2.3 to -2.7 degrees after a 1 to 1.5 inch drop. People running Tein coilovers or Eibach springs show up to alignment shops at -2.6 degrees on one side and -2.7 degrees on the other and the shop says there's nothing they can do. The stock arms are maxed out. There's no adjustment. You're stuck with that camber and your inside rear tire edge is going to wear bald in 15,000 miles. There's also a TSB (06-007) for 2004 and early 2005 TSXs where the right rear upper arm was defective from the factory. It pushed camber past -2.0 degrees on the passenger side even at stock height. If you bought a used TSX and the right rear tire's wearing way faster than the left, that's probably why. The fix under warranty was an OEM arm replacement but if your car's out of warranty you're buying this kit anyway so you might as well get adjustability on both sides.

Upper Arm vs. Lower Arm Kits - Here's the Difference

There are two ways to get rear camber adjustment on these cars. You can replace the upper arms (this Eibach kit or the SPC 67290 kit) or you can replace the lower arms (Ingalls-style kits). Here's why the upper arm approach is better. When you adjust the upper arm, you're only changing camber. Toe stays independent. You set your camber where you want it, then you set your toe separately with the cam bolts. Done. Lower arm kits adjust camber and toe at the same time. Every time you turn the lower arm to change camber, you're also changing toe. Now you're chasing your tail on the alignment rack. You adjust camber. Toe goes off. You adjust toe. Camber shifts. You go back and forth until you get close enough and call it good. We've talked to multiple people who started with lower arm kits and they all said the same thing: if they were doing it again they'd go with upper arms because alignment shops have an easier time dialing it in. Upper arms just work better.

Adjustment Range and What to Actually Run

The Eibach kit gives you +4.0 to -2.0 degrees of camber adjustment per side. That's enough range to bring a slammed car back to near-stock camber or to run aggressive camber for track use. For a daily driver on lowering springs or coilovers with a 1 to 1.5 inch drop, most people settle around -1.0 to -1.5 degrees in the rear. That's aggressive enough to help with cornering but not so aggressive that you're destroying tires. If you're tracking the car you can run more negative camber but keep in mind your front camber should always be more negative than your rear camber. If you're running -2.5 degrees in the front, don't run more than -2.0 degrees in the rear. You want the front to break loose before the rear or the car's going to feel unstable and unpredictable in corners. For a stock-height car with the factory TSB defect where one side's sitting at -2.0 degrees, you can use these arms to bring both sides back to -1.0 or whatever you want them at.

You're Going to Need an Alignment and Maybe New Lower Arms

After you install these arms you need a four-wheel alignment. That's not optional. Here's something to know before you go to the alignment shop: there's a good chance your rear toe cam bolts are seized. If your car's got 100,000+ miles or if you live somewhere with winter and road salt, those cam bolts are probably rusted solid in the lower arms. The shop's going to soak them in penetrating oil and try to break them loose with an impact gun. If they won't move, you're replacing the lower arms. That's not the Eibach kit's fault. That's just what happens to these cars. OEM lower arms from Acura aren't expensive but you need to know it might happen. If the shop tells you the cam bolts are seized and they need to cut them out and replace the lower arms, that's normal. Budget for it just in case.

Note: This is a complete kit with 2 arms (one for each rear corner). This is an upper arm kit - it only adjusts camber and leaves toe adjustment independent via the factory cam bolts. Upper arm kits are easier to align than lower arm kits because camber and toe adjustments don't affect each other. Four-wheel alignment required after installation. Your rear toe cam bolts may be seized - this is common on high-mileage cars or cars driven in winter conditions. If the cam bolts won't break loose with penetrating oil and impact gun, you'll need to replace the lower arms (OEM Acura replacements available). Budget for possible lower arm replacement during alignment. For daily driven lowered cars (1-1.5 inch drop), target -1.0 to -1.5 degrees rear camber for even tire wear. For track use, you can run more aggressive camber but keep front camber more negative than rear (if running -2.5 front, don't exceed -2.0 rear). Stock-height cars typically sit at -0.75 to -1.0 degrees rear camber. Lowered cars without camber adjustment commonly measure -2.3 to -2.7 degrees, which causes rapid inside tire wear. There's a factory TSB (06-007) for 2004-early 2005 TSX models where the right rear upper arm was defective and pushed camber past -2.0 degrees even at stock height - if you have uneven right rear tire wear on a stock-height early TSX, this is likely why.
