As for being the subject of protest rules..
I'm with ya there. Happened to me once in an old 'vette.
Of course now if you want to do this, you could always go to a junkyard and collect a good amount of "stock" springs and mix and match until you get the best setup for your car. People who do this professionally do this with many things. They call this "optimizing". Personally anyone who has the time and money to do this, needs to be racing in some other category. But there are always a few like this.
The way I've seen the rules applied in protest committee's has been if the option was available for that year and the car was in the same class it was a non-issue. Which leads me to a question
Why would you want SE springs in an SVT????
