Suspension And Drivetrain Buyer's Guide

Everything you need to put the power to the ground.

Jan 31, 2013

01 KSport

Kontrol Pro coilovers

KSport Kontrol Pro coilovers are the perfect choice for those looking to lower their vehicles and increase handling performance. Featuring 36 levels of damping adjustment, ride-height-adjustable lower mounts for retaining maximum suspension travel, a new patented pillow-ball design that helps combat noise while turning, electroplated shock bodies, and monotube design for efficient heat dissipation. All Kontrol Pro coilovers are backed by an industry-leading 18-month warranty.

02 Whiteline

Mitsubishi Lancer Evolution X heavy-duty rear 27mm adjustable sway bar

Whiteline’s 27mm three-point sway bar is dollar for dollar one of the best handling improvements you can make to your Evo X. Altering the length of the lever arms permits the roll stiffness to be tuned for different driving situations without replacing the entire bar. The stiffer the bar, the less body roll will occur. Whiteline bars are solid spring steel, not tubular, making them stiffer than similar-diameter bars.

03 ClutchMasters

FX Single-Disc clutch kit

The FX single-disc series features a high-leverage pressure plate design allowing increased clamping pressure while maintaining a near stock pedal feel. Four different friction disc configurations are available, including the new Fiber Tough material. Also included is a clutch fork bearing and alignment tool for a plug-and-play installation.

04 Tanabe

Sustec Pro Z40 coilovers

Brand-new from Tanabe is the Sustec Z40 coilover. The Z40 is a 40-way-adjustable, fully threaded casing damper with height adjustment that is independent from spring preload and also has new technology to prevent noise during spring movement. They are made in Japan to ensure the highest quality and durability. Special resin sheets prevent noise created by the spring shifting during compression. Large metallic bearings prevent wear and provide a quieter and comfortable ride.

05 KW Suspensions

Variant 3 Scion FR-S and Subaru BRZ coilovers

The KW Suspensions coilover for the ’12 Scion FR-S and Subaru BRZ enables owners to lower their vehicles 20 to 50 mm and retains enough travel to handle maximum load and dynamic loads during driving. Adjustable (and independent reacting) rebound and compression damping allow a truly individual performance-driving setup for technically demanding drivers. Compression damping adjustment conducted in the low-speed range, while KW engineers set up the high-speed preset, so decisive for driving comfort. The stainless steel construction internally and externally provides long-term durability and corrosion resistance from the elements.

06 Whiteline

Strut-mount camber/caster correction

The Com C front upper strut mount uses a high-duro rubber for +0.75-degree caster and -0.5-degree camber for more control without compromising ride quality or comfort. The Com C uses Group N–spec low-compliance rubber and twin-shielded bearing design. Drivers can potentially increase upwards of 5 degrees of total caster and -3.5 degrees of camber. Applications include FR-S/BRZ and Subaru WRX, STI , Legacy, Outback, and Forester.

Spherical Bearing kits

The Blox Racing spherical bearing kits directly replace the soft, rubber factory bushings. These rubber bushings contribute to the “sloppy” feel experienced by many during hard driving on road courses and racetracks. These spherical units allow your vehicle’s suspension to maintain a better and more consistent geometry during hard cornering and spirited driving. Proper geometry and setup directly result in better tire contact patch.

’07-’09 Mazdaspeed3 antisway bar kit

Cobb Tuning’s Mazdaspeed3 antisway bar kit was developed using sound motorsports engineering principles and further validated by hundreds of miles of on-track testing and competition on the Cobb Mazdaspeed3 Time Attack car. Overall roll resistance is significantly increased, allowing the driver to attack the corners, responding with razor-sharp turn-in, reduced midcorner understeer, and improved corner-exit balance. The bars have multiple settings both front and rear, giving additional adjustment so handling can be tuned to driver preference. The tubular design allows significant rate increases while reducing chassis weight.

32 ShepTrans

R35 GT-R transmission rebuilds

The R35 GT-R is an excellent platform that responds very well to power upgrades. But when adding power, the transmission will need to be upgraded to hold the additional torque and stress from hard launches. ShepTrans starts each build with a PPG First gearset, custom clutch snap rings, and Dodson FWD retainer and mechanical locks along with Selector piston shims, an O-ring and seal upgrade kit, an oil pump shaft upgrade, and blueprinting to address the most common problems. This allows abusive drag race–style launches and a clutch capable of holding well over 1,000 lb-ft and 1,600 plus horsepower.
