Titan Motorsports
What: Dry sump kit
Rides: Toyota 2JZ-GTE
Where: titanmotorsports.com
Titan's dry sump kit for the 2JZ-GTE engine is the result of years of R&D on the famed Toyota engine, and typically what was only possible for 2JZ full chassis cars can now be used on a factory MKIV Supra subframe. It fits with very little modifications and has been tested to 10K+ rpm on race engines.
Centerforce
What: Dual Friction clutch
Rides: 2013+ Scion FR-S/Subaru BRZ
Where: centerforce.com
Owners of the FR-S and BRZ can upgrade their stock clutch with this single-disc street clutch from Centerforce. The kit comes with a lighter billet steel flywheel and Dual Friction pressure plate/disc for added durability. You'll experience greater holding power and performance without wearing out your clutch foot.
Raceland
What: Ultimo coilovers
Rides: '02-06 Acura RSX
Where: raceland.com
Raceland is a big believer in offering coilovers that not only perform but can also go extra low on the drop, without sacrificing ride quality. The Ultimo kit uses stiffer spring rates and stronger shock valving to pull this off. Shock bodies are powdercoated and the spring perches have been anodized to protect against corrosion.
TruHart
What: Front camber kit
Rides: Various applications
Where: truhartusa.com
Whether your car is built for street or track, it's crucial to dial in your camber accordingly. But no matter which side you're on, it's in your best interest to use quality components, and TruHart's camber kits are such, featuring Hard Race bushings and ball joints. Its non-slip bottom mount design lets users adjust camber easily.
