Thoughts on the Koni Adjustable Rear Shock from Dinan (link: http://www.dinancars.com/product/d14...-series-e46-2/) as a far cheaper alternative to the TC Kline or the standard Koni Yellows? Seems like a perfectly good option compared to the TC Kline. Even if the valving is different, would it matter much between these in the rear and regular Koni Yellows in the front?
