Drag rims on S14 with no modifications to fenders? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hi guys, I tried to search but could not find the info I needed,

I want to know what 15" rims (width and offset) you guys use for drag usage that fit the S14 without needing to change anything?

Thanks so much

cdlong · 03-10-2008, 06:06 AM

you can fit any 15" on an S14 with out trying. what size tires do you want to run?

Rezlo · 03-10-2008, 07:07 AM

I would like to run some 26X10 X15's as they are quite easy to get here in SA,

Just worried about rim width, I presume 10" would be the best size to use for a slick like this right?

Still a bit worried that 26X10 X15 might be a bit small, ive been running 275/50/17 street ET's and I really battle for traction,

Another option is 29X11.5X15 or 29.5X13.5X15, I kind of want to get this right 1st time because the tires cost about $400ea here, dont want to get somthign that doesnt fit,

BTW im running 600whp RB25 in my S14,

What you think?

Thanks

just convert the inches to mm the 11.5 is your with of tire for ex. your 275mm tire really is 10.8 inches wide hope this helps you
so your 29x11.5x15 would be 292mms and the 29.5x13.5x15 would be 343 mm tire

Rezlo · 03-10-2008, 11:02 AM

Yeah, I know the conversion, just wondering what you guys fit that doesnt require modification?

Cheers

the rear has quite a bit of room inside for big tires. since you're going for a functional drag setup, you should run a pretty high offset, lke 15x10 +40 or something like that. check the max rubber thread and use a calculator to compare it with your old tires.

you'll loose a bit of gearing with the smaller tires, but with the better compound and tire construction you might be ok. some of the guys on ka-t.org are really into drag racing. they can probably help you choose a size better than i could.

note for those reading, according to MT's website, the "10" is the rim width. the cross section is 11.6 in this case. the 26x10x15 is roughly equivilant to a 295/47/15.

The problem is how low of an offset before suspension clearance becomes an issue. Zilvia is all about flushness so this is something that very few people have tackled.

MT ET Street Radial 2756015 (28x11.515) on a 15x9 wheel

Rezlo · 03-11-2008, 02:42 AM

Looks good, I see youve trimmed and flaired your fenders a little, how much space have you got on the inside and what offset you using? any chance of a slightly smaller offset to keep the stock fenders? also did it effect your gearing quite a bit using the 28"?

Sorry for all the questions, new to trying to fit slicks onto a fendered car.

Thanks

KA240SX808 · 03-11-2008, 03:23 AM

Not my car, It's Ivan from AMS, but IIRC

It's a completely stock fender, maybe with a slight roll

and 28" is 3.3" (12.5%) taller then stock
so 60 on the speedo w/ a 28" tire will actually be ~67.5mph

cdlong · 03-11-2008, 06:34 AM

i'm bored, here's some good stuff from ka-t.org

I have also spent a bit of time with a hammer rolling the fender lips and massaging other areas out of the way... I also had to trim my lower control arms slightly for some tire clearance... I still have some minor rubbing issues that will be solved soon....

BoostinGST · 03-13-2008, 08:59 AM

i tried a 29x11.5 on my s14, without a pull of the fender it isnt going to fit.

Rezlo · 03-13-2008, 11:21 AM

I went with some M/T 26X10.5X15 Street ET's (bias not radial) and some spinwerkes 15X8 with 5 7/8 back space (wanted 5.5 but they didnt have)

Should be a whole bunch better than it was!!! and should clear no problems

Rezlo · 03-20-2008, 02:20 PM

What I landed up with.

15X8 spinwerkes

26X10.5X15 ET Streets

cdlong · 03-21-2008, 06:44 AM

enough of that, mount 'em up.

Rezlo · 03-21-2008, 10:50 AM

I will soon enough, just got the car up on stands at the moment doing the 350z 13" track disk/rotor swap, and im busy building the RB25, after a full year of mid 11's it was time for a rebuild!!! this year i hope to dip into the high 10's
