SSR GTX04 wheels represent the pinnacle of SSR's lightweight engineering, crafted for drivers demanding maximum track response and minimal unsprung weight. Utilizing SSR’s proprietary FFT-R flow forming technology, this 1-piece monoblock wheel achieves an exceptionally thin inner rim profile with strength characteristics that rival forged construction. The design features ultra-slender spokes reinforced by single-step drop ribs and a thoroughly shaved center hub section to eliminate every excess gram of mass. The result is an ultra-responsive wheel that balances track-ready durability with a striking, minimalist motorsport aesthetic.

Features

• Subjected to a specialized post-machining shot-peening treatment to increase surface strength and fatigue resistance
• JWL and VIA certified while maintaining full compatibility with factory TPMS sensors and standard valve stems
• Shortened spoke connections and optimized back spacing maximize clearance for multi-piston big brake kits

A wheel is the rim the tire mounts on; it bolts to the vehicle's hub, and its diameter, width, bolt pattern and offset set how the tire sits under the fender.
