    They're a 127mm wheel so you can only put it in a 215 housing. The Et 137 is the drop in wheel for a 255 charger.

    yeah the ET-137 is basically the same thing but for your bigger X-charger. Both are lightweight wheels and come with spacers for the charger. The 137 is sweet sounds great i know i love mine.

    no but you will need a way to monitor as well as adjust your fueling. Some go rising rate fuel pressure regulator and an AFR gauge/wideband. Personally i chose the CMD and Auto tune set up.
