No comprimise in strength with the IFS hub as far as i know. You will need the spacers. Here is sky's kit (third on down) PN#TOY-FWS-001:Aseif007 said:Will the IFS hubs be weaker than the stock ones on the FJ-60? Will any year IFS Yota do, or is there a prefered year? And are Tacoma hubs compatible? I like the idea of a little more room between the tires and the steering. Is it just a bolt up application, and all I would need are the IFS hubs?
