![]() ![]() The final demo of the day was the long autocross. While remaining relatively easy to control at the limit, this tire's virtual-slick tread pattern produced very little noise as slip angles increased, and felt more abrupt at break away as the limit was reached. As expected, this tire offered the highest cornering capability, pulling nearly 1.2g around the skidpad. To bookend the demo we climbed into a third car, equipped with g-Force R1-S R-Compound Racetrack & Autocross Only tires. This was quite evident in the steady-state exercise of the skidpad, where the g-Force Rival felt as if it didn't lose much ultimate grip as the slip angle increased, with average cornering power at just over 1.1g lateral. During the product presentation earlier in the day, the BFGoodrich engineers talked about their effort to create a tire with a broad plateau of grip at the limit. As the tire reached peak grip, there was still audible tire squeal, but at a lower tone than the higher-pitched squeal of the g-Force Sport COMP-2. Building speed and bending into the arc of the skidpad circle, this tire immediately communicated its intentions, with direct steering response and stable handling as cornering force increased. On average we pulled just shy of 1.0g lateral with this tire. The Ultra High Performance Summer g-Force Sport COMP-2 felt predictable and progressive as it approached the limit, with gradual breakaway and plenty of audible feedback as the tires squealed around the circle. To warm up for the day and put the g-Force Rival's performance capability into perspective we started out driving on a simple skidpad circle, using track-prepped Mazda MX-5 Cup Cars fitted with 225/45R17 BFGoodrich tires from three different tire categories – the g-Force Sport COMP-2, g-Force Rival and g-Force R1-S. MX-5 Cup Car cranking around the skidpad on g-Force Rival The relative warmth of New Orleans in January was a welcome break from the wintertime cold and snow at Tire Rack headquarters, and also gave us a chance to experience the new tire before our regular testing season begins later in the year. Members of the Tire Rack team had the opportunity to sample BFG's new offering, the g-Force Rival at the NOLA Motorsports Park in New Orleans, Louisiana. In an effort to repeat history and rival the performance of all current competitors, BFGoodrich has once again focused its attention on the Extreme Performance Summer tire category. Fast forward to today, and nearly a dozen tires fit the category as a testament to demand from the enthusiast community and interest among tire manufacturers to develop the technology needed to blend real street capability and track performance. For a number of years the g-Force T/A KD was unchallenged as the "king of the dry" among street tires. While enthusiasts have always taken street tires to the track, the g-Force T/A KD's level of ultimate dry grip along with its streetable nature ended up starting a revolution in performance street tires.Īnd with that, the Extreme Performance Summer tire category was born. The g-Force T/A KD was a true street tire that delivered an extreme level (for the day) of dry traction, sought after by enthusiastic street drivers and autocross/track day participants who wanted a tire they can also drive to and from the track. Sure, DOT-legal R-compound tires delivered more dry traction, but they weren't (and still aren't) intended for road use. The KD suffix nomenclature pointed to this tire's intended purpose – Key feature: Dry traction. Please contact us if you have questions about the BFGoodrich Rival S 1.Back in 1998, BFGoodrich rolled out the g-Force T/A KD to fill in the gap between R-compound track tires and Ultra High Performance tires of the day. G-Control sidewall inserts impove sidewall stiffening to promote steering response. The tread is stabilized by twin steel belts and an Equal Tension Containment System (ETEC System) of spirally wrapped nylon to optimize the tire's contact patch and traction at speed. Lateral grooves are given draft angles promote consistent performance and wear.īFGoodrich's Performance Racing Core reinforces the internal structure which reduces flex to increase steering response. Large outer shoulder tread blocks and BFGoodrich's Extreme Tread Edge (ETE) design wraps the tread compound farther down the sidewalls to create more predictable feedback and maximum cornering grip.Ĭhamfered block edges resist feathering under extreme cornering and braking.
