witth adjustable LCA's would i see more traction by making them longer or shorter?

 

LCA adjustments would be used to center your rear axle within the wheel well; not a problem with a stock rear setup. An adjustable torque arm assists with traction as you can preload the rearend (pinion angle) so that when you launch hard you can optimize the pinion angle under load. The best mod for traction is sticky tires (i.e. ET Streets)!

 

As was said earlier, adjustable LCAs only re-center your wheels. If you want to modify them for more traction, get relocation brackets and then you can alter your rear suspension geometry for more front-end lift.

 

You really dont need adjustables. They are more for if you go with huge tires and have clearance issues. Do like Patriot said and get the relocation brackets.
