Pontiac Solstice, Saturn Sky and Chrysler Crossfire Coilovers

The Solstice and Saturn Sky share GM's Kappa architecture. Even so, BC and Ksport make separate kits for each, while KW has one kit named for both. Besides Pontiac Solstice coilovers, this page covers the Crossfire, PT Cruiser, Chrysler 200, Grand Prix and Firebird, fourteen kits in all.

Tell us if it is a Solstice or Sky, GXP or base: 1-800-460-9106.

Solstice and Sky

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.

RM, the monotube for strut cars, is on the PT Cruiser and 200 kits.

Notes in BC kit names: "Swift Front Only" means the optional Swift spring upgrade is offered for the front springs only on that kit.

Solstice and Sky

Code: Not in the kit names
Good to know: BC makes a separate rear-drive kit for each roadster, the Solstice from 2006 and the Sky from 2007, each in BR, DS, ER and ZX. KW has a combined "Sky & Solstice incl. GXP, Redline models" kit and a "Sky incl. GXP model" kit. Ksport lists one Solstice and one Sky kit.

Crossfire coupe and Roadster

Code: ZH (in KW kit names)
Good to know: KW's kit is marked ZH (2004 to 2007). Bilstein's two kits are named for the "Crossfire Roadster", both "Without Self-Leveling Suspension" and both naming the SRT-6. If you have a Crossfire coupe, look at the KW kit or call us.

Before you buy: the Solstice, Sky and Crossfire on coilovers

The Solstice, Sky and Crossfire are low-volume roadsters and coupes, and the PT Cruiser, Chrysler 200 and Grand Prix were rarely lowered at all. Owner reports on coilover suspension across this group are thin, and we found nothing solid enough to pass on. If you are building one, read the kit notes above and give us a call.

Kappa history

One architecture, two roadsters

WardsAuto reported on November 29, 2004: "Both vehicles are based on GM's Kappa architecture."

    Where builtThe same report said: "The Sky will be built at GM's Wilmington, DE, assembly plant".

Common Solstice, Sky, Crossfire and PT Cruiser questions

Can I put a Solstice kit on my Sky?

BC and Ksport make separate kits, so their Pontiac Solstice coilovers are not listed for the Sky. KW has one kit named for both, "Sky & Solstice incl. GXP, Redline models".

Which kits name the GXP or Red Line?

KW's two kit names: "Sky & Solstice incl. GXP, Redline models" and "Sky incl. GXP model".

My Crossfire is a coupe. Which kit?

KW's 2004 to 2007 Crossfire (ZH) names no body style. The two Bilstein kits are named for the Roadster. Call us before you order.

Will a PT Cruiser kit fit the GT Turbo?

KW's kit name says "incl. Turbo". BC's kit name only says FWD, so ask us.

Is ZX available for the Sky?

Yes. Both BC roadster kits come in ZX.

Anything for an older Firebird?

The one Firebird kit here starts at 1998. Call us about earlier cars.
