Lol. What's the point of this? Just do it on a car that it would seem more practical for. Looks low enough IMO
Slamming your family transporter doesn't sound like the most sound idea to be honest. If it was your car, then it's another story. But even still, lets be real, a mini-van isn't the coolest car to put on coilovers. Esp since it won't be using more than 5% of the coilovers performance improvements.
Atleast you can buy a cheap beater with that kind of money depending on how much you price the car as, and make that beater your project car.
