Im going to be running 19x10.5 22et with 275 tires in the rear and i wanted to lower the car, but without rolling the fenders. I was looking at either Tein S-tech or Eibach. IIRC doing searches in the past, it seemed people had different answers as to whether fender rolling would be necessary. I was just wondering if anyone was actually using this setup with tein or eibach springs and did not have to roll the fender.

 

Do you ever rub now? How you taken a peak at your upper fender lips to see if you'd rubbed and didn't know it?.

I don't own a Z, so I can't tell you based on the spec's you given if you'll rub our not. If you don't get the imput you need to be sure. If I were you, I'd pull out a rear spring and shock on one corner and put the suspension back together, minus the spring and shock. Then mount a rear wheel/tire on and slowly lower that corner watching your fender lip clearance. That will tell you your clearance right then and their. Hopefully you don't have to, but thankfully the rear suspension on these car's is incrediably easy to work on.

 

Sorry, can't tell you for sure since I rolled mine before the getting the exact same rear wheel setup as you. I do have the Tein S-techs and looking at it leads me to believe it would rub had I not rolled the fender.

 

Some folks have been able to get away without rolling, while others get some rubbing. This has to do with varying camber between different cars and amount of lowering you plan to do.

I haven't lowered my car (yet), so I don't need to roll it. But, by just looking at the wheel fitment in the wheel wells, it looks like I'd need to roll it if I drop the car AND maintaining it's stock current camber.
