Eibach Rear Camber Kit for 04-08 Acura TL

Eibach Pro-Alignment Rear Camber Kit - 3G TL

Your 3G TL's got a well-documented problem. There's no rear camber adjustment from the factory. Honda gave you adjustable rear toe through a cam bolt (that loves to seize up after a few years, by the way), but camber? You're stuck with whatever the suspension geometry gives you. At stock height, that's around -1.0 to -1.4 degrees and it's fine. Drop your TL on lowering springs or coilovers and watch that rear camber climb to -2.0 to -2.6 degrees or worse. Now you're burning through the inside edge of your rear tires in 15,000 miles and your alignment shop tells you they can't fix it because there's no adjustment. Eibach's Pro-Alignment rear camber kit replaces your fixed upper rear control arm with an adjustable arm that gives you +4.0 to -2.0 degrees of camber adjustment. That's enough range to correct a slammed TL back to factory specs or dial in aggressive camber for track use.

Here's Why the 3G TL Eats Rear Tires

The factory camber spec for the 3G TL is -0.5 to -1.5 degrees in the rear. Most TLs roll off the dealer lot sitting around -1.0 to -1.4 degrees. That's within spec and the tires wear fine. But lower the car 1 to 1.5 inches on springs or coilovers and you're picking up an extra -1.0 to -1.5 degrees of negative camber. Now you're sitting at -2.0 to -2.6 degrees in the rear. Inner rear tire wear on the 3G TL is so common that dealership service writers have called it a known issue, even on stock-height cars. Drop the car and it gets way worse. The inside edge of your rear tires is getting destroyed and you're replacing tires every 15,000 to 20,000 miles. Your alignment shop can't help you because Honda didn't build any camber adjustment into the rear suspension. The camber's locked in by the control arm lengths and mounting points. Eibach's camber kit fixes that.

Upper Arm Adjustment Is the Right Way

There are two ways to adjust rear camber on the 3G TL. You can replace the upper control arm with an adjustable unit (this kit) or you can replace the lower control arm with an adjustable unit (Ingalls-style kits). The upper arm approach is cleaner. When you adjust camber through the upper arm, it has minimal effect on toe. The 3G TL uses a multi-link rear suspension so there's still a slight toe change when you adjust camber, but it's way less than what you get with a lower arm kit. With lower arm kits, every time you adjust camber, your toe goes out of spec and you're chasing two variables at the alignment shop. Adjust the lower arm for camber, then you have to readjust toe, then the camber changes a bit when you set toe, and you're going back and forth. The upper arm keeps it simpler. Adjust camber, then set toe independently. You're done faster.

Watch Out for Seized Toe Cam Bolts

If your TL's got some years on it and you live anywhere that sees winter or salt, your rear toe cam bolts are probably seized. We've seen it on every 3G TL that's over ten years old. The cam bolt sleeves corrode inside the bushings and they won't budge. When you're doing the alignment after you install the camber kit, the tech's going to try to adjust your toe and those cam bolts aren't going to move. Soak them in penetrating oil ahead of time if you can. If they're really stuck, you might break the sleeves loose inside the bushings when you try to turn them. At that point you need new OEM lower control arms. The good news is OEM replacement arms from Acura are relatively cheap. Factor that into your budget if your car's got miles on it.

Installation and Alignment

The install's straightforward. You're removing the upper rear control arm and bolting the Eibach adjustable arm in its place. If you're also installing lowering springs or coilovers, do the camber kit at the same time. You'll save yourself a second alignment and you won't chew up a new set of tires while you're waiting to get the camber arms installed. After you install the arms, you need a four-wheel alignment. Don't skip it. Even though you're only replacing the upper arm, your toe's going to shift slightly. Get the car to an alignment shop and tell them you've installed adjustable rear camber arms. For street use, ask them to bring the rear camber back to factory spec, around -1.0 to -1.2 degrees. For track use, you can run more aggressive negative camber if you're also dialing in your front alignment to match.
