g-Force™ tires set g force recordSeptember 2, 2004 G force is one of the measurements engineers use to measure vehicle performance. Most often it can be found in magazine road tests where a vehicle's "roadholding" will be measured in g's. One g equals one times the force of gravity. Even some of the world's most exotic sports cars rarely exceed 1.0g. Typically they will score in the .8g or .9g range. Now a Nissan Skyline R-34 GT-R, tuned by Signal Auto of Osaka, Japan, driven by Signal Auto president Kousuke Kida, fitted with off-the-shelf, full-tread-depth BFGoodrich® g-Force T/A®KD street tires has accomplished the possibly unprecedented feat of breaking 1g in dry cornering, braking and acceleration. In a testing session June 10 at the Tire Rack test facility in South Bend, Indiana, Kousuke-san recorded a 1.08g lateral acceleration figure around a 200-ft. diameter skidpad. He recorded a 1.09g straight-line acceleration and braking deceleration of 1.13g. The 1.08g cornering figure is the highest ever recorded for a street car at the Tire Rack facility. "I've never heard of a street car achieving this combination of performance before," said John Rastetter, Director of Tire Information Services at the Tire Rack. "While we've had cars attain 1g in braking on our test track, only a few have ever broken the barrier in cornering, and this the first time that it has been achieved while accelerating on street tires. The g-Force T/A KD (tire) really delivered its key benefit of dry performance." BFGoodrich g-Force tires are the world's fastest street radials. In addition to setting the highest cornering mark The Tire Rack has ever recorded, they hold the current world record for street radials in drag racing, set by Dwayne "Big Daddy" Gutridge — 8.05 seconds at 181 MPH on 11/23/03. |
