The pull-type relief system and differential pressure control give stable operation across a wide range of boost pressures, and the mounting flange is unchanged from earlier SSQV generations, so it stays compatible with every existing HKS SSQV insert, recirculation fitting and recirculation kit.\u003c\/p\u003e\n\u003cp\u003e71008-AK001 is the standard silver-finish universal assembly — valve only, with no flange or piping supplied.

So this system deletes the middle muffler and uses a straight, unrestricted pipe layout into a free-flowing main muffler. HKS measured up to 35 percent less exhaust resistance than stock, which brought quicker boost response low in the rev range and gains of up to 5 kW and 15 Nm on an otherwise stock car — more once the ECU is tuned to use the extra flow.\u003c\/p\u003e\n\u003cp\u003eThe muffler internals were developed through frequency analysis to keep the sub-100 Hz highway drone that cheaper exhausts suffer from at bay, while bringing out the 200 Hz-plus mid-range that sounds sporty at full throttle. The result is quiet at a cruise and loud when you want it. The quad tips are a nod to the BMW 3.0 CSL: thick-walled slash-cut tips with a blasted satin finish and sound-deadening inner slits.

The carbon box shields the element from radiated heat, and the extra intake duct keeps airflow volume stable even with the filter covered, so intake temperatures stay lower and more consistent. HKS's own testing shows reduced airflow resistance across the whole range compared with the stock intake, and the complete system weighs about 2.6 kg against 3.1 kg for the factory intake — roughly 500 g lighter. A polished circular HKS emblem is included for the box.\u003c\/p\u003e\n\u003cp\u003eTwo versions are offered.

The G8X M cars ship with electronically adjustable dampers that are stable at speed but still stiff on real roads, even in Comfort. The HKSTUDIE SUS was developed to keep that high-speed composure while giving the car a genuinely better ride around town.\u003c\/p\u003e\n\u003cp\u003eIt uses monotube dampers with large-diameter pistons for consistent damping, and inverted front struts to resist the bending loads a strut sees under braking, acceleration and cornering. Both ends have fully threaded bodies, so ride height is set without changing spring preload or damper stroke. HKSTUDIE set the default with the front slightly lower than the rear to close up the big factory front wheel gap and improve stability at speed. Thirty clicks of damping adjustment cover everything from commuting to track days.\u003c\/p\u003e\n\u003cp\u003eHKS's Dual PVS valving firms up damping at low piston speeds and softens it at high speeds, cutting float and harshness and improving traction. A long, soft \"advanced\" bump rubber acts as a progressive helper rather than a hard stop. The front uses camber-adjustable spherical-bearing top hats and the rear CNC-machined aluminum top hats. The suspension error canceller is included, so removing the factory electronic dampers does not leave a warning light.

In HKS's own launch-control testing, the drag setup was about a second quicker to 100 km\/h than stock, with less loss in the wheelspin zone.

The springs are a variable-pitch barrel design that steadies the body, and HKS developed a new, more durable rear bump rubber for lowered use. The setup was chosen after testing at Fuji Speedway and Gunma Cycle Sports Center with racing driver Manabu Orido.\u003c\/p\u003e\n\u003cp\u003eThe same kit fits the BMW Z4 M40i (G29), which HKS fitted and confirmed on an actual car — but only Z4s with Adaptive M Suspension.
