XYZ Racing Hollow Rear Brake Kit — Pontiac SOLSTICE (90) (2006-2009)

The Kappa-platform Solstice carries more mass over its rear axle than its compact roadster looks suggest, and the factory rear discs were never sized for repeat hard stops. This XYZ Racing rear big brake kit for the Pontiac Solstice goes after exactly that: it gives the back axle the thermal headroom to stay consistent when you are braking deep into a corner and steering this rear-drive chassis on the brakes.

Because it is a rear-specific upgrade, it is about balance as much as outright stopping power. As a rear kit it is a matched pair of left and right calipers and two uprated discs. With selectable pad compounds and a larger, hollow-vaned rotor, it lets you set rear bite to match your front setup and how you actually use the car – fast road, the odd track day, or a Solstice GXP turbo being driven hard.

What this brake kit does for your 2006-2009 Pontiac Solstice

On a rear-drive roadster the back brakes do quiet but important work: they settle the car into a corner and stop the tail stepping out under trail braking. Fit this rear big brake kit to your 2006-2009 Pontiac Solstice and the first thing you feel is consistency – the rear pedal that held firm on lap one is still there at the end of a session, where the stock discs would have started to fade. The hollow-vaned rotor sheds heat faster and trims rotating mass at the rear hubs, sharpening how quickly the back axle reacts. Specify the Racing pad compound for a higher, progressive bite on circuit days, the Sport pad for fast road and the occasional lap, or the Street compound for quieter, lower-dust running on a car that still sees the road. Either way, front-to-rear balance stays under your control rather than the factory’s.

About the rear big brake kit

The XYZ Racing rear big brake kit is built around a vented, hollow-vaned two-piece floating rotor and a fixed caliper sized to clear the Solstice’s rear wheels. The hollow internal vanes pump cooling air through the disc far better than a solid casting, which is what keeps disc temperature – and therefore pad friction – stable when the brakes are worked repeatedly, while braided lines keep the pedal firm and the floating face stays flat under heat. Three pad compounds are offered: a Street pad for everyday use, a Sport compound that lifts bite and heat range without grabbing cold, and a Racing compound for sustained track sessions. The caliper is hollow-bodied as standard, with an optional Hollow Racing upgrade (no dust cover, rated 1000C, two-year warranty) for hard circuit work. Painted caliper colours are included free in Red, Yellow, Gold, Black and Anodized Black; a Custom Color in any Pantone is +£150, with premium polished-forged Titanium, Polished Gold and Polished Silver and candy Teal, Blue, Red and Orange finishes available. Discs are drilled or slotted at the same price, with two-tone anodized or titanium centre bells selectable at checkout. As a rear-axle kit it is designed to pair with a front big brake upgrade or uprated front pads, so the whole car brakes in balance instead of nose-heavy.
