theres a build going on and for the suspension setup they are using hpi big bores with integy msr8 springs. why is this? why not use the springs that come with the big bores? thanks
People mix and match every part on the market in hopes to find a good combo. The stock springs are a bit soft on the big bores. I also have a hellfire so I have the spring kit for changing to the factory spring options but the MSR8's fit well and replace the twin spring design with a single so they are now being used by modders that have them.
