A FULLY-adjustable, tubed, ball-socket, multi-link, coil-overs, the works for $2.5K? Cheap coil-overs are around $700-$900 alone, and if someone is building this car on a budget they wouldnt be going into rallycross, lol.
But, I, agree: $2.5K is a lot of money, regardless of what you are spending it on. It just depends on if it's worth it to the driver, or not.
