Question about wheel Offset

[monoculusjoe]

I'm getting some 16s and I need to know how deep of a lip I can get for these wheels before I get em. Thanks in advance peeps.:biggrin:

It all depends on your setup...

For stock height, stock camber you can run 7.5/8" width with as low as 35mm offset as long as you don't go wider than 195 tires. If you lower the car and dial in some negative front camber, you can easily go wider.

what is the stock offset? also, can you run 16x7 offset 35 with like 205/50 rubber and be fine? lowered that is.

Work wheels has a set of 16's with a 52mm lip.. that works out to 2+ inch lip... I'll see if I can find the model....

Keep in mind that big lips usually don't exist on smaller sized rims...

16x7 +35 is a good fit, and so are 205/50/16's but 205/45/16's are closer to stock diameter.

correction it's a 58mm lip....

Thanks for the feedback! I have the TRD Sportivo suspension setup Springs shocks and struts. It lowered it about 1 and 1/8 inches. I was thinking of going 17's too but I still am convinced that the 1.5 liter won't be able to push em.:thumbdown: Is anyone runing 17's?

My 17's are actually lighter than the stock 15" steel wheels! As long as you chose a good quality lighter wheel it should be fine. With tires, the wheel and tire are ~2.5lbs heavier than stock (33lbs stock 15" steel vs. 35.5lbs. 17's)

How comes ur 17" tire are heavier than the Stock 15" tire, I thought 17" tires have less rubber material so they shouuld be lighter?:confused:

Doesn't work that way for a few reasons...

The lower profile tires require different steel belts (more of them) to stiffen up the side wall. Different brands of tires are also slightly heavier than others...

Also on my 17's I run a larger diameter and wider tire, 215/45/17 vs. 195/55/15, which requires more material, which makes it heavier. Most 215/45/17's are in the 20-23lb. range. Most 195/55/15's are in the 17-19lb. range.

You can actually purchase the same exact tire in the same size and it will weigh 2lbs less depending on how it is built! A perfect example is the Yokohama Advan Neova AD07 for the Lotus Elise, since the Elise is such a light car and it comes with the AD07 as the OEM tires, Lotus worked with Yokohama to "fine tune" the tire and formulated a specific tire for the car. They found that a lighter car behaves better with a tire which has a softer sidewall (less steel) since it conforms to the road surface better and grips better. This comes at a slight reduction in "load rating" but in the Elise's case this isn't a concern since the car is sooo light.

If you go to www.tirerack.com and look for the Advan Neova in OEM Elise sizes you'll notice they offer two different "specs" of the tire. In the specs you'll notice the "lotus OEM" spec is 2lbs lighter (and it uses the same rubber compound!)

Hope that helps clarify it?
