Since it's bothering me, our RCE Yellow springs are 250 lbs/in, not 225.
Either way, you'll likely want to upgrade to a firmer system with new dampers for a track only car with "track" tires. Not a must do immediately, but eventually (and check the condition of the stock shocks).
Agreed on RE71R being a poor choice for anything other than trying to set 1 fast expensive lap.
