Question about spacers + overfenders - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

niSm095 · 11-10-2009, 05:48 PM

If I'm running a 50mm rear overfender on an s13 coupe, with 30mm overs up front, what size spacer am I looking at to achieve some level of flushness with 17x9.5 wheels all around on a 45 series tire?

I've been browsing the offset threads, haven't found much useful info.

you need to know what offsets you'll be running

I do....my bad forgot to include that. +15 on all four

Then you obviously have no clue what you're looking at.

You haven't even stated what your current offset is, or why you thin you need overfenders. I mean, if you're only running 9.5" wide wheels, you don't even NEED overfenders. With the proper offset and tires, a very mild pull takes care of it.

EDIT: Ok, you added +15. That is seriously all you need for the Wheel Fitment Thread. I KNOW there are 9.5" wide wheels in that thread with +15mm offsets. Find them, and see how they fit. Even if you don't find it EXACTLY, there is all the information you need to figure out how to fit them in that thread alone.

I'm guessing you have the MB Battles.

I use to have the same wheels but only ran a front over fender and it was flush with a 38mm spacer.

For the rear I would guess you need at least a 50mm spacer.

Maybe I don't really have a clue what I'm looking at, that's why I'm asking for help...

I have overfenders to cover up rear panel damage, cool?

I've obviously found pictures of battles on stock fenders, that does help, but I'm trying to get a better idea of what spacer to buy, so I don't buy unnecessary things.

Well, two things.

#1. If you have seen how they fit on stock panels, and your adding X-amount of overfender, just add that big of a spacer as well.

#2. Overfenders are fiberglass, and can be "adjusted" when installed. So buy the spacer that is close to what you want, and then install the fender to fit properly over it.

Both of those methods have been discussed, in-depth, on Zilvia before.

Also, if you're just covering up damage, and you aren't getting any wider wheels, then stick with 30mm overs. Less spacer will be safer and easier.

And stop hitting things with your rear corner panels. They are important parts of your vehicle.

Here is an offset calculator, which can give you a rough estimate of where the wheel will sit. True fitment comes from trial and error.

I continue to be amazed at people's inability to calculate proper offsets.

Given a current fitment and how much room one has on inside and outside, it is a simple matter of arithmetic to calculate offsets with new wheels sizes, etc.
