Model S Aftermarket Wheel Fitment/Offset Discussion

Would like to add my set up here:

2021 LR+ Raven Suspension currently lowered on 54mm/74mm links (will be going lower). Wheels are BC forged RZ815 finished in brushed clear. Specs are front Front: 21x9" ET30 (Michelin Pilot Sport 4S in 245/35/21) and rear 21x10.5" ET35 (Michelin Pilot Sport 4S in 285/30/21). No rubbing at all.

Edit I have tried uploading more pics but I keep getting image too large even though I have compressed the pic to 2mb

Thanks Pabla. That setup looks great. If you get the image problem figured out it would help to see a shot from the top, front, or back to help understand the fitment/level of 'flush'.

Car looks awesome, @pabla ! Same sizes/offsets (and tires) as mine - good to know they work well on Raven too. 👍

Okay so here are more pics with 58mm links in the front. A few things to add, I am waiting for the EV Tuning adjustable rear camber arms to fix the slight camber in the rear. Surprisingly since this set up is really light I am getting 160 wh/km which is Tesla’s rated efficiency. Ride isn’t bad at all considering the car is lowered. Handling is great, very neutral no understeer. Overall I’m pretty pleased with the setup!

Vossen HF3 Gloss Graphite 20" with Falken Azenis Fk510
Front: 9" ET35 245/40/20
Rear: 10,5" ET42 285/35/20 (6mm spacer)

No rubbing whatsoever and the car rides magnificently. Comfortable, yet handles great.

The car is not lowered yet, will do that this week. When I had 245/45/19 I made the links 9mm longer than factory - we'll see how low I can go 😜

Friendly reminder to always double check that the lowering-link is properly tightened 😅

jesus christ I guess we don't have bump-stops on our cars.

What's that like 275 wh/mi? That's what I get with my Vossens as well. Just goes to show that fatter wheels doesnt matter that much when you have good lightweight materials.

BTW, whats your measurement from floor to the top of the wheel arch front and back?

Its about 257 wh/mi. Yeaup I think the fact that the rims are lighter than the stock 21s it negates the extra width on the rear.

Fender height is about 28" on all 4 corners give or take a 1/4"

I have had the wheels on for two weeks now and I'm not sure if I have done the correct tire size choice. I think I want tires with a little less rubber/sidewall.

I'm currently running 285/35/20 on 10,5" and 245/40/20 on 9".

Here's a photo while the car is lowered. Links are 9mm longer than factory.

I have only found one user (@16P90DL) running 285/30/20 and it looks significantly better.

Thoughts?
 
Ok folks,

The two-digit number after the slash mark in a tire size is the aspect ratio. For example, in a size 295/30/21 tire, the 30 means that the height of the sidewall is equal to 30% of the tire's width. The bigger the aspect ratio, the bigger the tire's sidewall will be.

So, if you change that middle number, you're just making the tire TALLER, not wider. In the FRONT, that may cause rubbing. In the REAR, as long as it's only one value off (they come in increments of 5), you are generally okay - but you will affect the ride height of the car.

Also, generally a good idea to check if the tires will fit BEFORE you order new ones.....and you'll want 4 winter tires, not 2.
 
Hello again.

I'm on the search for the perfect fitment this coming summer and I was wondering if anyone can shed some insight on what specs I would need to get a fitment like this?

I *think* you'll need air suspension with camber plates and stretched tires so you can really dial it in so when you air it out it can sit riiiight above the wheel like that.
