Lowering the Rear

Yes the current ride height needs to drop and yes the ride quality needs to be improved. It was my understanding that SS springs are good for two things raising the rear for big tires and going hard off the line (straight). Not consider so much for handling. I would not want to use lowering blocks although I do appreciate the suggestions.

Thanks
You might peruse the system for some of @72bluNblu 's trials and tribulations as well as @autoxcuda just a couple that come to mind.

I went to the 'steering/chassis' under the "forums" and typed in 'handling' and this popped up.....there is a ton more to look at.
