Are you able to make 4.25" single stage foams for 4.25" Rovers?
Yes, I can make them but have not because there is no market for them. The single stage foam line is the slowest selling.
When I tested 4.25" Tall, 1.9, cut n shut, red dot HB Rovers I used the current 1.9 single stage Lil' Nova foams with closed cell tuning discs on a 3 pound MRC comp truck.
