I have those (I installed for my friend too) and they really give you more space. Other thing what help a lot is to adjust front wheel alignment as far front as possible (as much negative caster as possible). You can get about 1 cm more space behind the wheel.
One more: install a bodylift.
I have those spacers and 2" bodylift and 33x12.50R17 tires. No rubbing problems.
Thanks for the info. I have a 2" suspension lift, Tough Dog, all ready and my rims are 17x 9.5 I have removed some of the plastic mud think but when i go off roading in deep curves i have a problem.
In city or on road driving the No issue at all at any sercomstances.
You belive your recomantasion will solve this problem.?
