I was thinking drop coils in the front, but agreed if you're using spindles.My '97 @ 2/4 didn't ride any firmer than stock.
Spindles use original length shocks with original springs.
Hangers & shackles in the rear.
Rear = stock 'style' (compression/rebound) 2" shorter shocks.
All that that suspension stuff did was move the wheels up into the body a bit. Nothing done to the springs.
The vehicle is suspended by the springs.
Shocks control the springs action/reaction.
With the stock springs all round, the suspension only became firmer after the addition of some proper performance-oriented shocks actually designed for lowered vehicles.
The hangers and shackles change the arch in the leaf though don't they? That would make it ride more stiffly.
