Will the 30mm brake swap fit and clear my stock rims?  Thanks for any help

*Jeff240sx* · 11-06-2002, 08:36 PM

I know they fit under s14 SE alloys, cuz that's what I am running.  I have heard they fit under the s13 SE alloys, too.  Someone with an s13 should agree here.

Really, I thought only the 26mm calipers cleared stock S14 SE wheels?

*nismo270r* · 11-06-2002, 10:57 PM

Nopers...check out my install write up in the installs sections on the www.zilvia.net homepage.  I've got 30mm calipers under stock S14 rims.  Just enough room in there for them...where they're supposed to be! <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt='

SR20Fastback · 11-07-2002, 01:31 AM

Awesome, so I dont have to source 300zx rims now to do the swap. Though I still have to buy the 5 lug hubs <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/sad.gif" border="0" valign="absmiddle" alt='

ibanezxguy · 11-07-2002, 05:32 PM

Well those s-13 rims are 1 inch smaller and might not allow the 30mm swap... but im not sure so correct me if im wrong.

*Jeff240sx* · 11-07-2002, 11:36 PM

sr20fastback.  I think that they clear the s13 rims, but mabey you should do a search on FA, cuz that might be where I read it.
Also, you can either drill out the rotors for 4-lug yourself, or have just about any machine shop do it, so you don't NEED to get the 5-lug conversion.

for the record, 17x8.5 are big and heavy, what size tires are you planning of running; 235/40-17? anyways, offset is a poor way of finding what wheels ot run... it's important to know offset, to figure out fender rub and factors like that, but as far as calliper clearance, spoke design is the most important thing.

but here's what i've got for you on a 17x8.5" wheel you shold need about 30-35mm of offset... this would give you a total backspacing of 137.95mm and 142.95mm respectivly. which should put the wheel and tires under your fenders with minor trimming needed. (this is if you are running a standard shock/spring setup...) if you are running coilovers... you may have to step out to about a 25mm-30mm offset which whould give you a total backspacing of 132.95mm-137.95mm... that was the easy part... in summary: go with about a 30mm offset/137.95mm backspace wheel.

now we get to look at spoke design!!! <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/crazy.gif" border="0" valign="absmiddle" alt=':crazy:'> this part is all on you. and with the help of some wheel spacers any spoke design will fit!!! try the Volk GT-N they have a good spoke design and are pretty cool... SCC used the CE28's an they did well also. here's the link: http://sportcompactcarweb.com/tech/0211scc_projsilvia/

hope this helped a little,

yes the s14 se's rims will clear the 30mm brakes that is what i have on my car also.

planb · 11-13-2002, 07:35 PM

s14 se brakes will clear 26 and 30mm z brakes
s13 spoked wheels will clear 26 but not 30mm z brakes

tex240sx · 02-09-2003, 07:55 PM

I agree-- my '91 SE FB wheels won't clear the 30mm brakes. Wouldn't clear the 26mm either BTW... having to run a 1/4" spacer

gnuproject · 03-27-2003, 03:15 AM

can somebody tell me how to do the 300z conversion on my 95 4lug? What's the cheapest and easiest. Also I live by a junkyard so if you guys need parts california's got all you need. Lemme know, I might be able to help
