Upgrading to 20’s on a sedan

Looking to upgrade to 20’s on my sedan soon.

I want to go 9.5” front & 10.5” on the rear.

Im lowered 20mm f&r on KW HAS’s.

Just wondering what wheel offsets are confirmed along with what tyres sizes are being run on sedans.

Specs and photos appreciated.

Nice one mate, are you going to go with custom forged or flow forged/cast wheels?

If you narrow down to the brand/style you like, they will have the correct specs and photos for you.

I am running 20 x 10.5 's on the rear with +50's on w/ 285/30/20 and I had to raise the body up as it hit .It still touched after raising it up 1/2" on larger bumps on the road . I'm going to a 10" +57 to bring it in a 1/2 for better clearance and possibly lower the body back down slightly .If you want to run a 20x10.5 you'll need to run a 25 series tire to clear . My 30's hit the bumper when I'm lowered ,right below where it joins the 1/4 panel. I even trimmed my bumper cover on the inside to try and clear and still hit and the lip on the inside of the 1/4 .I wasn't about to cut the 1/4 so I'm going to a 10" .On the front I'm running 19 x 9.5 's +32 with 255/35/19 and the top of the right front tire touches slightly once and a while when turned lock to lock . I'm pretty low in the front but you'd be ok if you have a finger clearance

Hey Sanch,

Nothing in mind at the moment but prob flow forged, just wanting to see what everyone’s running in relation to offset and tyres sizes.

Michelin as3+ which are wide .....11.6 in the rear . I think the pilot 4s is 10.9 and the SS is 10.5 . That may have helped me but I already bought these tires and mounted them .I'm not willing to go to the 25 because the ride will be hard and I wanted more protection for the wheel in case of potholes because my wheels aren't cheap to buy and they are light so I went with a 30 .

That white car with that set up will touch .There is no way they could have anyone in the rear ....trust me I've tried to fit them in .If you're willing to touch sometimes then go for it .

At this height the rear tires hit the bumper going over larger bumps. These are 20x10.5 +50 .This is after I raised the body in the rear to gain some clearance ....I actually like the look raked

that white car is +50 in the rear like mine . Notice how the wheel extends past the body slightly. They are also running a 25 series tire .BC Forged showed this car to me and gave me the specs

None of those will work as I have 19x11 +55 and they are about as much as you can go outward as well as inward. I can't fit a credit card between my fenders and my tires.

actually, if you stretch your tires with a 285 or a 295, they might be able to work with mm precision. I'm running 305s in the rear

yes but you will need to adjust the camber and the height to make it work

I have 19"x 10" with a ET of 52 on 285-35-19 Michelin PS4S tires. I am stock height. I dont like my wheels to stick out passed the fender and with my tires they are perfectly flush.

If you haven't bought wheels yet i have a set of 20s that came off my sedan that are for sale. I can work out powder coating them any finish you want as well. -photo681.jpg
