i went from 17's to 20's, it was definitely a noticeable difference. I drove my friends Z the other day that has 19's on it tho, no difference.

 

how about 19's up front and 20's out back?

 

^hmmmm, not sure if i'm feelin that...need a better angle shot

 

Dude, what kind of hood is that????

 

That's hot.

 

just check out my car domain link in my sig

 

How about you guys' speedo? Doesn't things get outta whack when you go to wide or too tall?

 

I have no issues what so ever with my 20" setup. Im lowered on RSR springs and had no rubbing issues.

 

i also changed my rear differential, so I'm not sure what caused more loss, but the speedo is faster than i am actually going. When it says I am going 75 its 72/73. I had the cruise control on 76 and went right past a cop checking speeders.

 

I know for motorcycles there's a "speedo healer" that will correct speedo errors for anything from factory error to changing the rear/front sprockets. Is there a "fix" for the 350? The thing is...our car displays speed in two different places, with a Navi, that's 3 different readings...

 

wouldn't the speedo show a slower speed with 20's????...the wheel diameter is larger, which means the axle is spinning slower than with a smaller wheel

 

i cant believe how concerned some of you over the speedo maybe being off a few mph...you drive a 350Z...if you're worrying about a few mph, you bought the wrong car.

 

no one's worried...the odometer is a bigger problem, and i couldn't care less about that either
