Hi Mart,

While the new style front end is more adjustable most of the Rev.4 crew sticks with the old school mainly for it's simplicity. You will find a lot less wobble and more consistency from side to side and there's no doubt it makes tons of corner speed. With the new front end it's not uncommon to see things either get very loose and require rebuilds or the opposite, I have had many kingpins start to bind making things extremely erratic with the new front end. The old school front end being as simple as it is doesn't get tossed out of alignment easily and when it starts to get loose it's a few bucks to replace almost the entire unit.

Don't think for a second that because it's old and simplistic that it's not extremely capable. Just about every Rev.4 out there is running one including the winning modified car at Cleveland this year!
