(Track) Anyone running 18x9 40mm offset with 265 40 18

Anyone running this setup? Just want to see if anyone is running it and if they experience any rubbing. Mine is close but it might be okay. I am just not sure how much deflection it gets on track

Looks fine. Deflection is very small. If the zip tie fits you are good.

Is this a performance or non P? That backspacing looks real tight to me. I like to keep 5mm of clearance to the upright but the Master above is just that. If he says it's good then it should be. I always lean on the safe side because it's never good to find these things out at the track. I do run a 19x9.5 +35 on my P Car with a 265/35/19 but it's my street setup. For track i have 18x9.5 +22 and intend to go between a 265/40 and 275/40 with nearly -3.5 of camber so that should clear the fender. I'm not worried about the upright with the backspacing i'm using.

I usually use a microfiber cloth as my guide. If it fits between the tire and the knuckle you'll be fine. All you need is ~2mm. I would definitely recommend a zip-tie or two on the wheel speed sensor, but I can see that has already been done

there should be minimal deflection at the top. Interesting that you guys move the wire sensor. Is this kind of normal?

When running wide (265/275/285) tires you definitely want to move the wheel speed sensor away from the tire/wheel.

$100 mistake

in my case two since I broke both

I do bring a spare to the track so I can price gouge people when they lose theirs (just kidding)

LMAO!!!! that's a great idea, not the price gouging part but keeping Tesla spare parts on hand.

I gave my old fixed up one to UP at Laguna Seca, I just told them to return it when they get home. They ended up giving me a new one, how nice of them to do that.

I am still running on a wire that I solder myself, it is holding up

I have now seen enough Tesla on track now, I bet brake boiling and ABS wires getting ripped we will see pretty much every day

Those zip ties are not keeping the cable around broken place and during a turn cable is pulled. That eventually going to break it again.

 

[boyguan]

will a broken wire not allow you to drive home? aka error the car into not driving?

No ABS, no autopilot

No many things. Like steering booster. And turning wide sticky wheels without it while standing is almost impossible without destroying steering wheel.

it's even worse when you have a ton of negative camber.

Usually with more negative camber you have less traction when you're not cornering and therefore lighter steering at standing...

Why the 265/40/18 for the track over the 265/35/19?

Im wondering about +35 255/35/20s on 20x8.5s and MPP rotors. I think that setup would rub though and dont think 245/35s will have enough padding for the streets.
