Eric LaFerriere and Duy Bui Astound the World with Six-Cylinder Power, Break Xtreme Import Records Eric LaFerriere and Duy Bui have dominated six-cylinder performance standards on 275mm rear tires for several seasons, but the duo shocked the sport with three amazing blasts from their seldom-seen 2020 Lexus LC500 in outlaw doorslammer trim which culminated in a staggering 5.448-second, 266.11 mph....

Looking to take your valvetrain performance to the next level?
We’re now stocking GSC Conical Valve Springs.

What sets a conical spring apart from a cylindrical or beehive spring is harmonic stability.

A conical spring has varying diameter coils and a progressive rate which causes a self damping effect. If one coil reaches its harmonic frequency, the neighboring coils act to dampen the resonating coil. This effect dramatically decreases spring oscillations at high RPMs. Every GSC Conical spring offers a Super Finished surface treatment to go along with cutting edge, patented heat treatment procedures to make for the most reliable high performance spring available for the aftermarket.

If you’re building for performance and don’t want to compromise on valvetrain control, these springs are a proven upgrade.
Get in touch with us today to find the right setup for your build.

Following on from last week’s post, the Rover V8 has now had its time on our in-house dyno—run in, tuned, and ready to go.

With an aim of 300HP it put down a solid 316HP. It might not be headline-chasing power, but in a miniature muscle car tipping the scales at around 700kg, it’s going to be nothing short of wild.
