Speedthane Finally
the Latest Materials Technology
has been applied
to Stock Car Racing’s quick
fix. Speedthane,
is manufactured from the Automotive Industry’s finest Micro-Cellular
Polyurethane material (MCU), and consistently outperforms any other
spring rubber currently available. Speedthane has a Progressive spring rate. This
property is unique to MCU. Upon entry , the MCU will not give the
driver the ‘bump’ associated with conventional spring rubbers. Speedthane is available in 3 densities
or spring rates, so no more half or third rubbers required. This feature reduces spring sag and spring fatigue. Speedthane maintains it’s rate under
the most severe applications. Tested
at 180 F Speedthane retains 95% of it’s original spring rate, comparable
rubber products retain less
than 80% of their original spring rate. This makes Speedthane more consistent on long runs and hot track conditions. Speedthane lasts 3-4 times as long as
rubber in durability testing. This revolutionary product is only available through Lavigne Distributors of Manchester, NH. All profit from sales of the Speedthane product are donated to Kids First USA, a non-profit foundation that uses a Unique Motorsports approach to nurture an interest in Math, Science and Good Health in America’s Children.
