1: Why don't fenders come rolled from the factory, I mean isn't it there for a reason (helps the structural integrity of the fender frame).

2.I am thinking of getting the Ichiba Version II Bolt-On Aluminum Spacers, are they a good brand......And finally they say they are bolt on, are bolt-on's just as safe the regular deal?

 

My guess:

1. Fenders are generally stamped from flat metal sheets. Rolling would be an extra process.

 

The factory does have a rolling tool. But they will be getting one soon.

 

+1 , they are as cheap as possible

 

bump for question 2

 

1) Actually, the front fender are rolled on the Z. It's only the rears that are unrolled. An unrolled edge is stronger since the metal is formed in an "L" shape. When you roll it, you create a "U" shape so there's not as much metal perpendicular to the body surface to stiffen it.

2) I'd guess they're as safe as any other spacer as long as you check the nuts occasionally to make sure they don't work loose. I know somebody (not a 350Z) that lost a wheel due to an improperly installed spacer. I'm sure there are people who've lost wheels due to improperly tightened lug nuts so just about anything can happen.

Any reason you want the bolt on vs. the bolt through? Other than not having to change studs to something longer?

 

seems like less of a hassle too install why, is it less safe.

 

Arguably so, and it's impossible to check the tightness of the nuts holding the
spacer to the hub without taking your wheel off. If it's only a dd/street car I wouldn't
worry about it.

 

Dave, I wonder why the front fenders are rolled, and the rears or not. I understand your point about rigidity, but also wonder why this differs front to rear.

Obviously the front wheels can turn, requiring adequate clearance; but I wouldn't think that is a factor here (rolled-fender-lips).

This is a question... I don't have an answer but would like to learn.

I've always wondered the same thing.
