The second tC, 2011 to 2016
Codes: AGT20
Before you order: The BC kit name adds "Swift Front Only"; ask us what that means. Ksport lists its kit as fitting through 2018.
Scion xB, tC and xA Coilovers
These three Scions share a badge but are very different cars. The xB is the boxy one, the tC is the sport coupe, and the xA is the little hatchback. We sell Scion xB, tC and xA coilovers, but no kit fits more than one of the three. Pick your Scion, then its generation, and you will have just a few kits to choose from, with BC Racing shown first.

Pick your Scion first
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.
Which Scion is in your driveway?
Each Scion has its own kits
Start with the model. Then the year narrows down the kit.
xB
The xB came in two generations: the original box from 2004 and the larger car from 2008. There are seven sets of Scion xB coilovers between them.
tC
The tC came in two generations, 2005 to 2010 and 2011 to 2016. Scion tC coilovers come in ten kits, including a BC Extreme Low kit for the first car.
xA
The xA had one generation, 2004 to 2006, and there are three kits.
BC Racing for these Scions
Six BC kits across three models
BC Racing makes three series for the Scion xB, tC and xA: BR, DS and RM. Every kit comes in BR and RM except the tC Extreme Low, which is BR only. DS also comes on the two standard tC kits, 2005 to 2010 and 2011 to 2016. Free shipping on BC Racing kits in the continental US.
BR, RM, and DS on the tC
There are three BC series, and which ones you can get depends on the model.
BR comes on every BC kit
One knob with thirty clicks sets compression and rebound together. The tC Extreme Low kit comes in BR only.
RM comes on all but Extreme Low
RM is an inverted (upside-down), single-tube shock built for MacPherson strut cars, with the same 30-click knob.
DS is for the tC only
It has the same knob as BR, plus a digressive piston for steadier control. BC makes it for the two standard tC kits.
Four of these BC kit names include "Swift Front Only". For Swift Springs on any of them, use the Custom Build for BC Coilovers page and talk to us first. On the tC, we suggest the standard height kit before Extreme Low.
KW, TEIN and Ksport
Three more brands make kits for these Scions. Call 1-800-460-9106 to compare them.
KW makes two tC kits, one per generation, named with the ANT10 and AGT20 chassis codes.
TEIN covers all three models. Street Basis Z fits the xA, the first xB and both tCs, and TEIN also makes Flex Z and Street Advance Z for some of them.
Ksport makes one kit for each model and generation, five in all.

Before you buy: what Scion xB, tC and xA owners run into
What Scion xB, tC and xA owners report most often, from owner forums, recalls and service bulletins, and what each point means for your coilovers.
Rear camber goes negative on a lowered tC
tC, first gen 2005 to 2010 and second gen 2011 to 2016
ScionLife owners report more negative rear camber after lowering the tC, as its independent rear gains camber when it drops. One second gen owner on a max drop wore out his rear tires before fitting adjustable camber arms. Lower means more rear camber and more inner rear tire wear.
Before you install: Get a four wheel alignment after the springs settle. Plan on adjustable rear camber arms if you go well past a mild drop.
Front clunk from loose nuts or unseated springs
xB and xA, first gen 2004 to 2007
On ScionLife, a 2005 xB owner traced a front clunk after lowering to a top strut nut backed off halfway up the stud. Another thread found a spring not seated in its lower perch, and one poster found loose strut to knuckle bolts. These noises come from the install, not the parts.
Before you install: Torque the top nut, strut to knuckle bolts and top mount nuts to spec, and recheck them after the first few hundred miles.

Scion xB, tC and xA coilover questions
Can a tC kit go on an xB?
No. Each kit is made for one model, so the box, the coupe and the hatch never share a kit. Pick by model, then by year.
What BC series can my Scion get?
Every BC kit here comes in BR and RM except tC Extreme Low, which is BR only. DS also comes on the two standard tC kits.
What does "Swift Front Only" mean?
It is part of the name of BC's xA, xB and second-generation tC kits. It means the optional Swift spring upgrade is offered for the front springs only on that kit. Call us before ordering so we can explain what ships.
What about the xD, iQ and iA?
The xD and iQ have their own page, along with the iM. For the iA, call us and we will find the right kit.
Is the FR-S on this page?
No. The Scion FR-S shares its kits with the Toyota 86 and Subaru BRZ, so you will find it on that page.
Is there a warranty on BC kits for these Scions?
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.
