I am planning on getting the Danahoe Coilover Front Suspension for my 2007 Tacoma 4X4 Sport Access Cab. My local shop suggested adding leafs to the back with new shocks for a mild lift and general towing abilities. I am looking for the best set up for good ride quality and maximum towing capabilities. I'm not sure whether Add-A-Leafs like the Deaver 3 pack are good for towing, or if I should go for the Dakar replacement Leafs, or should I go with airbags or a combination of springs and airbags. First and foremost I need towing capabilities and if anything I want to increase my towing capacity if possbile. I also do not want to have bouncy rear suspension which requires me to have a load in the bed to keep things smooth.
