Anyone off hand know what the primary spring rate of a stock 07 phazer gt is? I'm adding 25hp nitrous shot to my sled and from what I've heard some of these phazers are borderline on hitting the rev limiter at WOT. Was gonna do a little searching and get a spring w/10-15lbs more finish rate in the spring. Any help would be nice. Thanks!
 
You would want less finish rate.

More finish rate = higher rpm than stock spring

Less finish rate = lower rpm than stock spring

The stock spring is a 20 kg initial and a 117 kg finish rate.
