Hi Matt, the rears were HPI blue but the front were standard predator blue. To be honest don't worry too much about the HPI Touring car springs, I was just experimenting a bit and they were slightly harder than the hardest predator "silver" spring. The car would be fine with the Predator silver on the rear.
As with any setup its all down to how we like our cars to handle and i've no doubt you will probably adjust things to suit your style but hopefully it will give you a good base. I know that the other team driver Will Johnson was running a completely different set-up to me on his car but he has a much more aggressive driving style.
Feel free to get in touch if you need anything/help and i'll do my best to help out
