I have a set of enkei rs rims laying around from my MZ20 and what do you know,they fit..... well sort of. The front rims fit on all hubs, but the rear rims have a smaller inner circle for the hub (does that make sense ?). Also the front rims are 8" and rear rims 9", any legal problems there ?

I like the look the enkei's give it, but want to know if it is worth the $$ to get the rims machined out.

heres a comparo

Take a search for Stagea and wheels.... I think you'll find the car wants identical rolling diameter AND footprint all around, otherwise the ATTESSA system can throw a tantrum. Anyone? I know they want the rolling diameter to be the same, but I'm pretty sure I've read about the width thing before. There must be a reason that all 4 wheels on a GTR are exactly the same size/width...

i like the ones in the bottom pic, they fill the guards better. also i think getting the rims machined to suit seems like a whole lot of effort.

as for the tire width. if you think about it, a 235 wide tire on an 8" rim will have a different fitted shape to a 235 tire on a 9" rim, this could reduce the rolling diameter, probably not by much, but it maybe enough to mess with the ATTESA. its just safer to rim equal width and size rims.

you can have different width rims front to back with ATTESA no worries at all. can have different offsets too

what you do need is an equal rolling diameter between the fronts and rears (left to right too, naturally)

you are correct in saying that a given tyre with a given width and profile will have a different overall rolling diameter if it is fitted to rims of differing widths due to sidewall angle. however, ATTESA has some le-way in it's design - it allows for the difference between a brand new tyre rolling diameter and a warn one and also allows different brands of tyres to be fitted front to rear (believe it or not, not all 235/40/18's fit the same due to sidewall construction etc) but i digress

i have always had a soft spot for the enkeis but i'm a sucker for good fitment (or at least better) so will say the second set as they 'fill' the guards more :(

thanks for the replies guys. you have all put my mind at ease now :( you are right about the guard filling issue. even the 18" rims look like 16" on a stag.

thats a nice wheel there RBPOWA

question #2

i would like my wheels to come out to the guards more. some have recommended +20 spacers. are they illegal ? do they shorten wheel bearing life ?

thanks for all the info, very much appreciated.

spacers are not responsible for any loss of life of wheel bearings any more than lower offset is - they both do the same thing by making the wheel stick out more. i doubt the wear on the bearings (if any) would be enough for you to EVER notice

i believe spacers are seen to be illegal (?) however if you do choose to get some make sure that they are hubcentric bolt on as these transfer the load through the hub and not the studs!

it's hard to tell from any pics you've shown us to determine what width spacers you would want and you've not told us where exactly you would like your wheels to come out to.. so the easiest thing for you to do is grab a ruler or a tape measure, hold it against the edge of your wheel and measure how much further you want it to 'poke'. that's the width spacer you will want. keep in mind i think (from memory) 27mm is needed to meet the length of the standard wheel studs - if your wheels don't have pockets in the back for the studs standard studs to protrude into once you have a spacer bolted to the hub then you'll need 27mm spacers minimum or to shorten the studs in your hub (which i wouldn't recommend incase you want to ever remove the spacers without needing to replace the studs)

on the other hand, if you are looking for new wheels pm me (or for any other wheel related advice) and i'll be more than happy to help you find something you're after :(

so are you saying that i could have got 245's or 255's on the rear and 235's on the front? and it wouldnt put the attesa out (note - i have 18x8's all round..)

if so thats sooooo gay... cos the guys actually were going to give to wider tyres on the back for the same price... :(:);)

i don't know the exact dynamics of the system but you can get away with slighty different tyre sizes... i wouldn't want to puch my luck though - just get the same all round. i've seen a number of gt-r's in japan running staggered sets without problems so it can be done although one would think they put plenty of thought into it first.

i wouldn't ever recommend a 255 on an 8" wide rim either

In NZ spacers can be legal if they are machined to support the wheel like the hub does (i.e. nut just hanging off the studs).

Regarding different wheel sizes people sometimes have different profiles to acheive the same rolling radius e.g. 9in with 265/35/18 on the back (=static radius 301mm) and 8in with 235/40/18 on the front (= 301) but a good tyre spec sheet will also show the loaded and dynamic radius which shows that they behave differently under load while driving. This may still be OK for the Atessa but I myself will use only the same width tyres front and rear - and after all wider rear tyres only really make sense for rear drive only cars.

ps I find this new way of listings posts a pain in the arts.

thanks for all the help guys, so very informative can't thank you enough. i think i will forget about the spacer idea too then ! i want my car to be as legal as possible.

I don't really think the wheels can come out that much further any way due to how low it is. It looks like it will start scrubbing on things. It needs to stay practical for daily driver too so no crazy -camber wanted lol.

My car is running 18x8.5 with 225/35r18's on the front and 18x10 225/40r18's on the rears with a pretty aggressive offset and i have no issues..

Those tyre sizes sound pretty small to me - a 225 on a 10" rim is an inch narrower than the rim.

Now I know that there is a 'look' for that kind of thing. But for regular use, I'd personally be running wider rubber all round.

A 245 on the front, and 265 on the back perhaps?

that rear tyres doesnt look any where stretched enough to be a 225 on a 10" either...

what offset is the 18x10 as well?

a mate of mine has a set of 18x10 +20 LM GT's, they only JUST clear the rear strut, and stick out of the guards. they also have 235's stretched over them. i'd say your rear rims are 18x9, 18x9.5 at most.

What is your gaurd lip to centre of hub measurements? What shocks & springs do you have?

Hi skidkid. is that measured with the wheel off ? sorry i am very new to this sort of thing ?

i am running hks hipermax perfomer coilovers and as you can see on the rear, the wheels must be just scrubbing it. don't know spring rates, only that it looks like there are two different rate springs on the one shock

So did I... if you mean this sort of thing:

Is that the new way of listing that you're talking about? I found that my post style had been switched to that way one day, and I hated it. But I discovered that you can switch back to the 'normal' style by using the "Options" button at the top-right-corner of the page, here:

post-32445-1235198153_thumb.jpg

Just select "Switch to: Standard" instead of "Outline" ("Outline" is the weird one in that first picture).

a little OT but HTH...

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
