The toughest part , in my opinion, is the same thing Vipers had to fight in World Challenge. Due to the engine size they have to run simply awful restrictor plates. Hopefully ALMS will view the 2 second gap and either reduce the weight on the Viper , or let them use a more open plate. This outing was not just a showing for the new GTS-R, but also a testament to ALMS that they may need to relax a few of the restrictions on the Snake to get it into a competitive position - unlike SCCA alot of folks have confidence in the ALMS to work towards equality. I think it is very important to their program to have the Viper back , so some leeway may come about to make the Viper more competitive , though all understand this is a learning/testing year.
