New roll center adjusters allow you to raise the upper arm taking away camber gain. Less camber gain will calm an aggressive front end on a high bite track. This is particularly useful on the XTI as it is difficult to use the long upper arm conversion. 2 mm and 2.5 mm arm spacers and hardware. The thicker the spacer, the less camber gain (flatter upper arm). This will make your car more "round" and smooth in the corners of a high bite track. For the most front end grip on low traction, leave the stock arrangement."
