Oh boy....
I really want to give you the full can of beans, but old man @
humfrz would say not to.
But I'll be nice, you just got the car drive it. Enjoy it. Don't "mod" it yet. Talk to other fellow owners before doing something silly as putting a body kit with out planing it out.
I would start doing a deep dive on other body kits in this forum. That should point you in the right direction. Then look up wheel set ups other people have used on their rocket bunny kits.
Also FYI not a whole lot of love with rocket bunny kits. But I'm sure you already know that.
