Looking for rims (20") 07 M35x and other questions

[mikesd1980]

I been debating wheels for the car for a couple weeks now. I live in PA(close to philly) and been thinking of 20" rims. Before a few issues I had to get of my 04 Audi A8L(had it for a tough 6 years) and the wife picked out the M35x(I wanted something simple for daily driver. ie 08 impala or 06 toyota avalon) since we have had a 04 FX35 AWD for 7 years now with no issues. So now we have 2 infiniti's in the house(only cause she say we can take them to the same Mechanic(Peruzzi nissan dealer)).... Anyways, I been looking at ways to help me like the car more(its nice stock but need more).

Its a base 07 M35x, silver. I already plan on doing OEM nav upgrade(pretty cheap), stillen cat-back exhaust and brakes(and maybe coil overs), Xenon kit(low beams and fogs), trunk wing and the stock system sucks horrible so I have a box and amp already, It just have to get wired.

Sorry for the non topic post but I am looking for some nice wheels, 20". And whats a good tire size? I like more rubber.

Welcome! 20" rims look cool with a nice drop but you mentioned something that makes me think you might want 19's instead. The oem's are 18 with 245/45R-18 if you go up to 20 you need to maintain the same diameter wheel which means the rubber would be 285/30R-20. This means you need a rim that is 20x10 or larger. This also means you need to mess with the offset of the rim so it's not too close to the suspension links. You mention that you prefer more rubber. 30 profile tires are like nothing is on the rim it gives you about 3.37" of sidewall. I'm not sure what offset you would need to make this work.

Upgrades are a great idea, from what you mentioned it looks like you want performance and aesthetics.

For performance I would do the following:
Motordyne spacer 5/16"
Uprev tune
Z-tube (Leave the stock airbox)
Any cat back system but be aware the AWD versions and RWD versions are different.
Optional: MREV2 lower plenum and isothermal gaskets.

I was hoping I can do something close 255/35 or close to that with 20" rims. Can I do a staggered set of wheels on the M35x? When I was on the Audi forum a few people did it on the A8's but its some rule with picking right rim width's and tires. Any help is appreciated.

If I change the door and rear speakers, will that help with the sound. The stock system is not loud at all and I have been using MP3's. When I put the box in, I dont want it to drown out the highs.

for an AWD car it's tricky to do staggered. Basically the rule to follow is the overall wheel diameter between the front and back must not exceed something like 3% I believe. Any reputable tire/wheel shop can advise you properly. Just in case ask them if they cover any AWD system damage due to staggered setup and see what they say lol.

I think adding a sub should be alright. You can always turn down the BASS settings to get a bit more higher end but typically you'll need more wattage to move the sub to sound at the same level as the mids/highs anyway unless your box is a bandpass with dual 12's pushing 500w each lol

Mine is awd i have 245/45/20 no problem. Its too much rubber though i want to downsize to 40 or 35 profile. Staggered you cant rotate so you will have uneven wear. My set up is 20x9 ET38 sits perfect!
You got much better roads in PA low profile shouldn't be harsh at all.

I would say 245/35/20 is the way to go

[mikesd1980]

Thanks for the responses guys. finikM35 do you have pics of your car anywhere? The roads near Philly and NJ is kind of harsh. I caught plenty of bubbles in my tires from hitting potholes with 255/35/19 tires. When I went to 20", I was able to 275/35/20 and it was fine. I think I will go with 245/45/20 when the time comes.

45 profile makes rim look smaller id say 40 profile is perfect

[svard75]

Me thinks your speedo will be off. You'll actually be driving faster than your speedo readout is telling you with anything larger than 35.

Stock is 245-45/18
+1 is 245-40/19
+2 is 245-35/20

Provided the rim widths are the same between the sizes.

you can run this with a 20x8-20x9 depending on what style has what size available for you. If you wanted to go 275/30/20 all around you could do that with a 20x9.5-20x10. As for staggered on an AWD M most people will shun it because of the altezza system or whatever it's called but people have done it and usually run a 245/35/20 up front and a 285/30/20 rear.

is your car lowered or the tires just fill in the wheel gap?

[finikM35]

Lowered on D2s

[mikesd1980]

finikM35, who did your uprev tune? The places PA and DE do not do AWD cars on the dyno. Im looking to do this after I get the exhuast put on.

What is the difference, before and after?

[finikM35]

I did street tune with Seymore from this forum. If you want dyno there is a place in Long Island NY with AWD dyno (Real auto Dynamics) its more expensive though
