Thanks, and well done. Hopefully someday this ~doesn't~ have to be a custom order. We all expect a review Mark.

>I'd stay away from a front sway upgrade, IMO...

+1, but I guess you can always try it.

On a side note, I know a local buddy SCCA racer who consistently got ~slower~ lap times when he added a stiffer rear sway to his RWD car. He just wasn't getting the same grip. He took them off, and his lap times dropped again to his norm. My point is they aren't necessarily a good thing for your style of driving and/or car.
