Anyone have ARB bumper on 4-banger?

Does anyone have an ARB bumper on a 4-banger, a 4x4 AC in particular? I was wondering if the extra 100+ pounds slowed them down too much.

 

the engine lugs so you have to regear, when you brake the rear lifts up so you need to do both bumpers together or you risk an end over. ok I'm kidding

On an old Dakota had ,the custom steel bumper i got used, softened up the front a bit and pulled it down maybe 1/4" tops. It didn't seem noticably slower. Similar application even though its not the same truck,dunno if that helps ya.
