how hard is it and what should it cost?

 

You can do it yourself, I did it is easy. Use a wooden baseball bat and take your time. I left the car in the sun for an hour then jacked it up, took off the wheel and rolled the lip.

You will be suprised how thin the lip is and how easy it is to do.

 

The Z is beautifully designed car. Is having another 1 inch width of rear tire really worth it?

 

Or you can rent the tool that bolts to your lugs and does it right.

 

Its not hard you can do it with a base ballbat or rent the fender roller And a heat gun.

 

its easy to do badly..it's difficult to do it perfectly

 

what does this comment even mean? rolling the fenders just folds the metal edge of your fender up that would cut into the tire if you're too low and your wheels are too wide. its not even noticeable from the exterior of the car except the overall appearance looks 10x's better because you can fill have no wheel gap and not tear through your tires.

On another note, you can rent my fender roller. PM me for details.

 

+1...and how much would it cost to get a body shop to roll the fenders for you?...just curious

 

Depends on where you go. I doubt the average body shop will have a fender roller and any reputable shop wont use a bat. The lip could also be hammered up by a body shop but that would cost more due to paint/body work afterwards. A hotrod shop would be more likely to have a roller and more experience in my opinion. But if you take your time and do it right, it takes about 45 minutes to an hour per fender to do a good job without cracking the paint. So if they charge $50-100 an hour labor, it could be $2-400.

Again, anyone wants to rent a roller and heat gun, PM me.
