Thanks for the follow up. I went thru the steps of ordering a M3 LR AWD on the Design Your Model 3 website and the only options were: Color, wheels (18" or 19"), and self-driving. The $2K acceleration boost option was not there. I also sent the Elon Twitter quote to the Lead Tesla Advisor, who replied: "Track mode is only available for Performance Model 3 vehicles with the premium upgrades package. " So it appears that they changed their mind for 2020. Has anyone ordered a 2020 M3P without the performance upgrade? Did it come with Track Mode?
I did SCCA Autocross in FM class about 12 years ago. The KBS Mark III race car is still in the barn. My track days are over, but I still sometimes feel the need for speed and am tired of working on ICE and energy-wasting brakes. I will probably go ahead with the Performance model with the upgrade, then try to sell the 20" wheels and summer tires, as also suggested by mattack4000.
Thanks. I will most likely buy the performance with upgrade and sell the 20s as you and others have suggested. Who do you think might buy them such that I can make $1500 (That would be great)? They have a different offset (35mm) than the other M3 wheels (40mm), but can they be used on a one-motor or AWD M3? Do they fit other Tesla models? Do they fit other makes? I do want the bigger brakes as well as track mode. The rest of the performance upgrade is mostly cosmetic fluff and the 20" so-called performance wheels are heavy and draggy, plus all of the other negatives I listed in the first post.
I see the stock 20s with new tires listed for $2500-3500 here and on my local FB Tesla page. Seems like they sell relatively quickly too. Not sure what people are putting them on.
Hey don’t forget that the performance upgrade comes with the bigger rotors and calipers. Along with that means that the rotors have that stupid “step” so that means the 19s you get either have to be machined or made with that in mind. If I ever change rims, I’m swapping to MPP brakes or something that eliminates that issue.
Thanks. I would only buy wheels specifically designed to fit the performance brakes. There are even 18" wheels that do, like the Modern Spare 18" x 4" kit and others from Tire Rack and TSportline.
I dropped from the OEM 20" wheels at 28.75 lbs. each to 18" Titan7 T-S5 wheels at 18.3 lbs. each. The Titan7 T-S5 wheels are machined to account for the 3mm lip. I'm happy with them so far...
Thanks. I looked at their website..those wheels look great and are fully forged, so much tougher. And they are carefully matched to each application. What tires did you use and did they maintain the same overall diameter? Did you notice any improvement in acceleration due to the much lower weight and rotational inertia?
I'm using Michelin Pilot Sport A/S 3+ tires in the stock 18" size (235/45-18). The car does feel livelier, but I never performed any before and after comparison times. My main goal for the switch was pothole protection...
Interesting. I guess potholes are a problem even in CA. Here in New England in the spring, they open up due to freezing and thawing, then become invisible as they fill up with water from snow melt or rain. Is there any sidewall bulge, even slight, to also protect against curb rash? We would appreciate any picture(s) you could upload. Thanks.
"I do want the bigger brakes as well as track mode. The rest of the performance upgrade is mostly cosmetic fluff and the 20" so-called performance wheels are heavy and draggy, plus all of the other negatives I listed in the first post." But they look fantastic. I have them on my M3P and would not want to change them. Believe me, it's pothole city round here atm too. It's also stomach churning quick regardless of how heavy the wheels are. I also get 310 miles estimated range @ 100%. IMG_2993 by rincewind posted Apr 2, 2020 at 3:30 PM
OK, perhaps you are too busy to take a picture...That's OK. My main question is: how far does the sidewall bulge extend beyond the wheel to protect against curb rash? Could you please measure or estimate that? Many thanks.
Harder than I thought to get a good pic. The tire (Michelin Pilot Sport A/S 3+) does stick out beyond the rim. I can't remember how the 20" OEM wheels were on the front side, but on the back side, the wheel does stick out beyond the tire..
Thanks! Good picture that shows a slight bulge. I think the 20" OEM wheels and tires, wit 0.35 cross section, have even less, plus the rim is closer to the road than your 235/45-18.
So true - I'm probably a bit paranoid, because I bent a wheel and blew out the side wall after hitting a pothole in my VW R32 (225/40-18 tires). Of course, no mobile phone service and raining hard outside. At least the R32 came with a spare, otherwise who knows how long I would be waiting for a tow.....
Yes, not having a spare is an issue. I am looking at a Modern Spare kit. Did you also consider Martian Wheels MW03, also forged 18" wheels that fit the performance brakes? There is a thread about them elsewhere on TMC: Martian Wheels MW03
