Hello, I just purchased a 2016 f type s and looking to change the wheels. I’ve gotten very confused with the offsets needed. I tried to research the best I could like what it was on factory etc but because there are options available I wanted to see if someone could help. Car is all factory atm not lowered, or bigger brakes.
picture of my wheel attached if it’s needed

I’m looking at 19x8.5 front (only offset avail is +30) does that work?

19x9.5 rear ( options are +22 or +35) this is where I got really confused

thanks for any help!!

 

Here is a site that you will find useful.

Here are the OEM offsets for the various wheel sizes available on the V6:

 

thanks. So 50 front and 27 rear. Will the numbers I mentioned work or do I need to find these numbers exactly

 

Another wheel fitment site that lists original specs is:

Thanks for the sites!
Does anyone have experience with or know if I could get away with 30 in the front (factory 50) so difference of 20
22 or 35 in the rear (factory 27) so a difference of -5 or +8
or do they need be exact? This wheel I’m looking at only comes in these offsets listed so I’m unfamiliar with this situation or if I need to look at something else

thanks for any further insight!

 

They don't need to be an exact match to OEM offsets.

Many owners have pushed their offsets out by as much as 17mm with custom adapters. I have 15mm adapters myself. I personally wouldn't go past 15mm on the rear, but there looks to be a little more tolerance in the front (should be verified). So +30 front/+22 rear may work.

I personally wouldn't go with anything that would move the wheel face further inward (i.e. the +35 fronts you mentioned), for aesthetic reasons.

Did you check out this site I posted? Not sure if you saw the link.

Allows you to visualize and compare different wheel dimensions.

 

the 15mm spacers have been confirmed with the 20” wheels but you can use that information along with your 19” wheels specs and input those numbers into the wheels calculator to figure out if offset will work for you. Just make sure your specs don’t push the wheels further out than the 20” with 15mm spacers.

for example, make sure the your 19” fronts don’t push past 9J x 20 ET40 (20” wheels with 15mm spacers).

 

Edit: had incorrect numbers. Here’s the correct calculations (if I’m still writing, please fix it as I’m doing this quickly on my phone).

I just did the front calculations for you. 8.5J x 19 ET34 is the max you should go so with 8.5J x 19 ET30, that would poke out 4mm too far and scrape the fender.

 

While +30 / +22 can work from a tire/fender interference perspective, it will affect handling. I had tired pushing out merely 12mm on my R and to me, handling including braking suffered.

 

Must've been something else then?

A wider track will improve cornering due to the same weight being distributed over a wider track, thus lowering the roll point (picture an isoceles triangle: if you widen the base, it will tolerate more lateral force before tipping over).
I can't imagine effect on turning radius being very dramatic. I certainly haven't noticed. I suppose you might if you're regularly making tight turns at full lock in parking lots, driveways, etc?


Anyway here's a picture I took yesterday:


Left side, looking towards the front of the car. 255/35r20, 15mm spacers, camber -2.0

I think there's another 5mm there?
