looking at getting new rim 5Zigen GN+ wondering if i should get 15 or 16 ?
and whats +35mm or +42mm offset mean ?

 

16.

It depends. 15's are lighter and will provide less unsprung weight. Many think 16's look cooler.

Steve Dinan of BMW tuner fame once told me that the only reason to put on bigger wheels was if you needed to in order to install bigger brakes.

Whatever you choose, enjoy your new wheels!

 

15s to inspire better acceleration
16s to inspire better look
the choice is yours.

 

Its a fit how much acceleration difference do you think there will be with lighter wheels.....

Unless you are running turbo kit or high boost s/c the weight of your wheels won't really make much of a difference.


The fit is slow....

 

just like girls, 16 is better



kidding haha

 

Unsprung weight affects many things, not just acceleration. Overall handling and braking are improved with less unsprung weight. See here for more info.

 

35 and 42 in short term is pretty much how big of a lip youll have. Depending on the total width of the wheel....Like i had 15x7 with +35mm offsets and had an one inch lip. If you had 15x7 with +42mm offset the lip would be smaller....Lower the number of offset,bigger lip youll have.

Hope that helps...if any of it makes sense!

 

i think i am going get 15 and use my current tires save some money :0

 

I've had both on my car but honestly the better of the 2 was the 15's. Hope this helps

 

Thats what I did with my 15s .

But my 16s are in the mail!!

Either one will look good. Shit, I have 14" 92 GSR wheels on right now with a 60 series tire while i wait for my new ones and they look good haha. I woulda kept them but my buddy whois letting me borrow them wants em back..

 

16's for sure....hands down.

 

14's r better

 

16's
35 offset.

 

Never save money on tires. This is the most important part of your car. the performance of your vehicle depends on your tires. for what my opinion is worth, you should just wait till you can afford wheels and nice grippy tires. unless your not concerned with performance, and if this is the case, you should be getting 16's. i will never tell someone how to spend their own money, but if you need to save on tires, you may want to evaluate wether you can afford wheels. that was in no way an insult, just my thoughts.

 

if your a spirited driver.


this goes the same on a motorcycle.

" cheap tires are expensive "

 

As long as your not tracking or AutoXing the car then who cares. The stock tires will be fine. Like I said, I did it with my fit and was happy with the money I saved.

 

Speaking has someone who has just switched from the factory Dunlops to Michelin Pilot Exalto PE2's, I can tell you that there is a world of difference in street handling, ride and noise between the two.

 

Have not heard that phrase before. i love it!

 

Size is your choice; there is such a mixture of wheels that some 16" wheels weigh less than some 15's. But the biggest factor is the tire weight since the weight is on longer radii its harder to turn or stop. If you use 15" wheels,205/50x15 is our choice and if its 16" 205/45x16. For better mpg stick with 175 or 185 section tires of correct diameter.
Offset is the measurement how far the wheel center sticks out from the hub. Increasing the offset means the wheel is closer to the hub and decreasing offset moves the wheel further out, increasing of course the likelyhood that the tire will rub. And yes 7" width rims are pretty much the most width you'll need on any wheel.

We haven't seen any wheel with offsets less than 42 mm that didn't have rubbing issues or need for installing tiny tires.
