They do not allow for complete tightness and centering when tightening lug nuts. It is very common for a wheel to come off when spacers are used. Also, you will most likely need an alignment after putting on the spacers because the contacting part of the tire is in a different area.why are they dangerous, i think it would give it better handling.
You mean a total swap of the rears then I take it for the width, I am guessing rims molded in the offset would not be much better due to the change in weight distribution so..... yet another hurdle I need to overcome. I was fearing this but it seems I will now need another suscription to some sought of Jeep magazine for ideas.Especially if you put alot of stress on them, its a terrible idea. On an off-road vehicle it isnt a terrible idea, its disasterous. Think about it this way, you are either adding another set of lugs that could be put on off-center, mis-tightened, stripped, or you will be making the threads of the stud shorter, giving you less grabbing area for the lugnut, and a higher chance of it stripping and losing a wheel.
Not to mention you have to take into account the fact that you are changing the weight distribution of the car. By spreading it like that, you are putting more stress on all of your suspension parts.
Im not sure any other way you can get your desired results without using them other than getting a wheel with a different backspacing, or just getting larger axles.
Dear god those are massive lol. But I think 3rd gens either take those or 1.5" to fit 4th gen wheels?
This is what I'm going to be running in order to put the black ZR1 wheels I've been wanting on. There was a red Z28 at F-Body Week last year brought down by Blazin' High Performance that was running them. They looked pretty solid and I've got shots of him doing a pretty sweet burnout.
