I sorta came to the conclusion that I could use the 450lb springs since MoParty. The car has always had a good ride, but for MoParty I always set my single adjustable shocks to full stiff. Well, after we were done with the 3S, I forgot to loosen my shocks up again and it’s definitely not too stiff. It actually feels much more even with how the rear leafs ride, so my thinking is I can bump up to the 450’s then adjust my shocks softer again.
