I'm looking at getting some Enkei RPF1s in SBC, going for a 18.85 +40 possibly for the front. Anyone know if this will fit okay or would I need to go closer to +30?

Kinkstaah is right, the wheels will never fit but with stretched tyres you might be ok. You will need 235/30 for the front And likely 255/25 for the rear

i tried to get heroic and squeeze 275’s on the back but the passenger side has scrubbed away about 2mm of sidewall. With a +25 offset I’m gonn need to downsize to 265/35/18

I also adjusted the camber to negative 1.25 degrees

The wheels have 215/35 and 225/35 on them. I’m ok to roll fenders but if it’s gonna be sticking way too far out i’d rather not waste the money.

 

thanks for the advice guys. Maybe i’ll try and find 18x9.5 +22 and run staggered tires

If I were to go the 40, would it poke or something?

The higher the offset, the closer to the car. +40 will not fit as you will hit the suspension unless you are using a really skinny wheel. Try to stick between +25 and +35, width depending

That doesn’t sound right for a 10.5. I’m not saying it’s impossible but the tyres would be completely stretched to their limits, plus with such a low sidewall, its not the correct fitment for a r34.

 

i have. 235/40 stretched over a 9.5 wheel up front

the 10.5 will 100% poke out but with a stretched 255/35 or 245/40 you might be in luck

it mostly comes down to ride height and your suspension set up 

 

this is how the 235/40 looks on the 9.5 (+20)

As mentioned above, higher positive number = closer to strut.

Nismo sizes: 8.5" +35, 9.5 +38

Okay well that rules out the +40s. So hard to find the right size in this colour I want. Would I be able to fit a 10/10.5 on the rear of a R34?

Your idea of 'fit' is different to others (and different to mine, which is also different to others)

10 +38 is a relatively common size at the rear of the R34.

With a square setup, the rear of the R34 pokes more than the front does, which was a surprise to me when I put on a square set of rims, or at least it did on my own car.


Like all things - What do you want to do with the car? This will determine what kind of fitment you really want. Talking 225 on 10's means I'm not the best person to advise as I am a more 265 at the front on a 9in rim kind of guy.

But making it fit is a question of maths and geometry really.

shit man, the coupe must be different to the sedan because im running 10.5 +25 on the rear and im about 7mm from touching the coilovers lol. +38 id have no chance.

 

i guess these things are best to just lie under the car with a tape measure

https://www.willtheyfit.com/index.php?width=265&aspect=35&diameter=18&wheelwidth=10&offset=38&width2=265&aspect2=35&wheel_size=18&wheel_width=10-5&offset2=25

 

According to this, it'd be 6.8mm closer to the suspension Strut. 

Note, did say 10 +38, not 10.5 +38. I had a 9.5 +27 on the back so I obviously had much more room on both sides.

This is just my personal opinion but do not stretch your tires too much or else it makes the wheel look like hub caps.

As if that's the reason to not stretch like that!  How about driving on the sidewall?  Or loading the sidewall completely contrarily to how the engineer designed it to be loaded?  Or how about setting it up to be popped off the rim edge when you hit a rock?  Or completely defeating the point of rim protectors on the sidewall of the tyre?  Or ruining the dynamic performance of the tyre?

Well yes, and all that too! 

But my pet hate is “Stance nation” crazy camber. I just don’t get it.

How about 18x9+40 245/40/18 all round 

The offset is too low for the front I believe.

Use the website willtheyfit and put in your current setup, get the measurements, grab a tape measure and see the difference for yourself.

Yeah I don’t know the setup atm I want to run 18x9s all round if I can with out the wheel sticking out 

18x9 + 30 is what you’re after my friend

    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
    • Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
    • Hi All, putting the engine back together and everything is perfect except have this plug left over.. any ideas what it is for and where it goes? Is on cold side under the intake plenum *note not a stock plug, as everything has been modified Cheers
