cartridge emulators??

[l3uddha]

what is the purpose or cartridge emulators for the front forks. I know race tech makes a pair; I'm assuming a set of race tech flat rate springs would go well.
are the cartridge emilators worth the money? this is for a track GS.
thanks

emulators and straight rate springs are a definite yes!!emulators make forks act like cartridge forks(kinda)but it is a neccessity on the track.
