This is the Core-RC Long Length High Response Spring Tuning Set for Off Road Buggies. Developed by Schumacher engineers and high level drivers over a wide range of conditions, from low grip dirt to high grip carpet. These springs improve the responsiveness of the cars, compared to the alternative CORE RC and Schumacher Big Bore Springs. They feature less coils, have a thinner wire diameter, and offer a handy weight saving; An average 4 grams per pair over previous CORE RC Springs. Because the spring stiffness increment between spring rates is very small, it allows fine suspension adjustments. These springs are intended for use on the rear of the Cougar Laydown, CAT L1 EVO and other cars using big bore shocks.
