spindles, struts, rotors, calipers, rear end is different. Springs are different, brake booster and ,master cylinder are also different. You can just look at the boosters and know they aren't the same.
I have a 93 lx which I converted and I left the 4 cylinder stuff in and it rides and brakes well. To answer your question, the spindles, sway bar, struts, rotors and brakes are different between the 4 and 8 cylinder cars.
so if i buy some strange struts, will i have to swap to V8 spindles or what? Ill leave them on there until i do a 5 lug conversion if itll work fine and stop well.
