Acura TSX Coilovers

Acura TSX coilovers are sold by chassis code: CL9, CU2, CU4 or CW2. Most kit names on this page use them. The first TSX was based on the European Accord. A second generation and a Sport Wagon came later. Find yours below, with BC Racing first.

Call 1-800-460-9106 with your VIN and we will confirm the code.

Animated illustration. It shows where coilovers sit on a car, not your exact kit. Depending on the car and the kit, coilovers can lean forward or back or stand straight up, and some cars use a separate spring and shock in the rear. Your ride height depends on the kit and how it is set up.

What the four codes mean

Here is which cars each code covers.

BC Racing for both TSX generations

BC Racing has more series for the first TSX

BC Racing coilovers for the TSX come in four series: BR, DS, ER and ZX. The CL9 gets all four, and the 2009 to 2014 car gets BR and DS. BC also sells an Extreme Low kit for the first generation, in BR and DS. Free shipping on BC Racing kits in the continental US.

What each BC series brings to the TSX

Here is which series fit each generation, and what they do.

BR and DS, both generations

BR and DS each have one 30-click knob that sets compression and rebound together. DS adds a digressive piston for firmer control.

ER, 2004 to 2008

On the CL9, BC's ER is an upright shock with an external oil reservoir and separate 30-click adjustment for compression and rebound.

ZX, 2004 to 2008

ZX is the series BC calls its "most track-tested" system. It is sold here for the CL9.

Extreme Low is a separate kit, and we suggest starting with the standard one. Call us and we will help you choose. To add Swift Springs, order through BC's Custom Build for BC Coilovers page.

TEIN and four more TSX brands

Here is what each brand makes for this car. Call 1-800-460-9106 if a code on your car does not match.

TEIN lists thirteen TSX kits. The CL9 gets four, Mono Sport among them. The CU2, CU4 and CW2 Sport Wagon get three each.

KW has one kit for the CL9. Its CU2 kit, 2009 to 2014, is named for the sedan and the wagon.

Fortune Auto kits are hand-assembled in Powhatan, Virginia. Fortune has one kit, for the CL9.

Feal has a kit for the first-generation TSX.

Ksport has kits for the CL9 and for 2009 to 2013 cars.

Daily sedan, wagon or six-speed CL9

The daily sedan

Keep the drop mild and the shocks soft. A TSX should still feel like an Acura on the commute.

The Sport Wagon

The Sport Wagon has kits of its own. Pick a coilover kit named for the wagon, or for the sedan and wagon.

Kits to look at: TEIN CW2 kits, KW CU2 sedan and wagon
The six-speed CL9

For track days, BC's ER adjusts compression and rebound separately, and ZX is its most track-tested series.

Kits to look at: BC Racing ER or ZX, TEIN Mono Sport or Flex Z, KW, Fortune Auto, Feal

Before you buy: what TSX owners run into

Most TSX owners bought the car for a smooth, well-built daily sedan, and that is how most of them still drive it. You do see the odd lowered Acura TSX, and BC Racing lists four series for the first generation, but the owner chatter about suspension trouble is thin. One pattern shows up again and again, on both generations.

Rear camber and inside tire wear when lowered
First and second generation TSX, 2004 to 2014

TSX owners on AcuraZine report rear camber of about -2.6 to -3 degrees once lowered, and faster wear on the inside edge of the rear tires. Owners say rear camber is not adjustable without aftermarket arms. Dropping a TSX on coilovers adds rear camber that the stock arms cannot take out.

Before you install: Plan an alignment with toe at zero after the install, rotate tires often, and add adjustable rear arms for a big drop.

The TSX story

The TSX started as the European Accord

Acura announced the TSX in March 2003 and based it on the European Honda Accord. It came with a 200 hp 2.4-liter i-VTEC four and a six-speed close-ratio manual.

  1. 2004
    The first TSXIt had a double-wishbone front and a 5-link rear with double tubular wishbones and an aluminum knuckle (wheel hub carrier).
  2. 2009
    Second generationIt got a 201 hp 2.4-liter four, with a double-wishbone front and multi-link rear.
  3. 2011
    The Sport WagonIt was shown at the New York auto show in March 2010 and reached showrooms that fall.

Both generations have double wishbones up front. Find the code on your car, then pick from the kits above.

Questions about Acura TSX coilovers

Does the TSX Sport Wagon take its own coilovers?

With TEIN, yes. TEIN lists the 2011 to 2014 Sport Wagon by its CW2 code. KW names its 2009 to 2014 kit for the sedan and the wagon.

What is the difference between CU2 and CU4 kits?

TEIN names some kits CU2, for 2009 to 2014, and some CU4, for 2010 to 2014. The kit names do not say what separates the two. Check the code on your car, or read us your VIN and we will match it.

Which BC Racing series are sold for the TSX?

BR and DS are sold for both generations. The 2004 to 2008 car also comes in ER and ZX, and BC adds an Extreme Low kit in BR and DS.

Is the TSX related to the Accord?

Acura based the first TSX on the European Honda Accord. On this page, we list only kits named for the TSX.

Can a lowered TSX still be a daily driver?

Yes. On TSX coilovers, a modest drop, soft shock settings and an alignment after the install keep it comfortable. You can firm things up later.

How many TEIN kits fit the TSX?

TEIN has thirteen. Four are for the CL9, and three each go to the CU2, the CU4 and the CW2 Sport Wagon.

Is there a warranty on BC Racing TSX kits?

BC Racing North America currently lists a two-year limited warranty on full kit orders, subject to its warranty terms. Each of the other brands sets its own warranty terms.
