has anyone had any issue with using spacers on the Z?

I'm looking at the H&K ones that performance nissan sells

My tires on my setup are close to rubbing the rear shocks and am thinking of getting 5mm spacers. I'm not nuts about the idea, but wondering if anyone has tracks their car with spacers.

Is the 5mm so little that it shouldn't be an issue? I don't rub on the street, but am not 100% sure if they'd rub or not on a road course with my Zeal coilovers (which are thicker than normal) I know 5 mm is almost nothing, but I need practically nothing - just a little more space to seperate the shock and tire

thoughts?

 

aside from them looking cheesy when you look at the spokes, they work fine. Most won't notice it, but some will. Before I got my new front offset wheels I ran spacers for a week or 2 just to see if I liked how it looked and handled with the wheel pushed farther out. I was very glad when my new wheels arrived though, as the spacers up front were very noticeable behind the wheel

 

Can we use the same studs w/5mm spacers, or do we have to buy longer ones to ensure adequate thread engagement? I'm thinking of getting some of the same spacers.

 

5 is the largest I felt comfortable using with stock studs - anything longer and you won't get enough turns out of the lugs
