Is winter done yet?  Group: Members Posts: 511 Joined: 26-August 03 From: Minneapols, MN Member No.: 1,082  |
Hi guys/gals,
Now that the AX season is officially done up here in the north, it's time to start thinking about winter "improvements". At the beginning of this season I set my alignment/ride height/corner balance and just left it as is all year, focusing on driving. I'm contemplating trying to drop the front of the car down another inch in an attempt to transfer a little more of the weight up there. Right now I have about 2.5" of suspension travel in the front and don't want to sacrifice any of that. In order to lower the car I would have to chop the struts and put shorten inserts in. To justify this, I wanted to verify that the camber curve would still be acceptable. I made a quick excell sheet graphing the camber gain as a function of A-arm deflection. Hopefully this will be useful to other people as well. As of now, at rest the A-arms are at about +3 degrees. On the bumpstops they are at about -10. By lowering the car an inch they would start at about -3 degrees and assuming I cut the struts 1.5 inches on the bump stops would be at about -19. I took some quick measurments on the car but they are by no means extremely precise. Here is the graph... Attached image(s)

Aaron, alot of rules say exactly this. this is the reason I don't have raised spindles either, but instead have chopped housings. Moving a suspension point is not legal.. Technically the wheel spindle is a suspension point. however the use of any shock choosen by the owner is legal. brant |
