The difference is the range the push rivet can clamp -- the BMW rivets can only handle the thickness of the fender metal and plastic wheel well liner, and if you try to add a mud flap it won't work -- the rivet becomes too hard to push and you risk cracking the paint on the hole in the fender...

The park distance sensors normally react to objects about shin to knee height. So as you pull close to another car bumper, etc, they should turn on. They won’t react to curbs. That would be a situation to tap the button preemptively to turn on the cameras and sensors if your car is so...

I don’t know how thick those flaps are, but I found that Toyota part 90467-05090-B1 is a suitable replacement for the BMW push rivets, but with a slightly longer stem. It will accommodate connecting the wheel well liner to the edge of the wheel well with the extra thickness of mud flaps that...

Objects in rear view mirror may be closer than they appear ... because the mirror fell out and got closer to them.

Try fewer ones (1-3), try smaller ones, try black colored ones, try a more aesthetically pleasing shape, etc. This phenomena, while it creates an intense buffet noise, is very simple and really easy to disrupt. It happens because smooth flow around the A-pillar leads to an instability, and...

I believe this was discussed before and it was just fixing typos and bad translations.

The reality is that the solution is even simpler than a lot of these brute force fixes, but nobody is really analyzing the problem properly or applying fundamental aerodynamic expertise. I posted in another thread that you can fix the problem with a couple small plastic bumpers (1/4" to 1/2"...

That is a very fair price too. I had to make some for my M2C, and custom cut them from the same material -- spent a couple hours templating and fitting them, and sourcing the right size plastic rivets. To be able to buy them all ready to go for $29/pair or $52/four is a heck of a deal.

I am mixed on ceramics -- yes they have some great benefits, but they also require periodic reapplication/maintenance to maintain the capabilities and benefits. I have a ceramic coat on my M2C (body and wheels) and it's good but I think regular wax would also be good if I was giving it a reload...

They are body panel joints -- you may see spot welds or adhesive beads under the trim piece. The channels double as rain gutters. Don't know about the Supra, but on most BMW models there are threaded boss mounts in 4 places under the trim pieces that can be used to attach a roof rack. On BMWs...

You need to make sure the lug bolts (or nuts) have the same mating surface ("seat") shape as the aftermarket wheel. Some wheel mounting holes have a conical seat, some use a spherical seat. I have seen both types of wheels fitted to the Supra. The wheel seller/supplier should include the...

The interesting thing is that a lot of what you mentioned is typical BMW. I crawled all over several Supras, and the resemblance to a BMW, down to nuts and bolts and manufacturing techniques, is pretty much 100%. Toyota may have had a hand in the design and development, but the manufacturing...

There is no correlation between VIN, LE number, or position in the spreadsheet. LE numbers were assigned randomly by Toyota USA and are not related to production order or any sort of provenance. It's really just a limited edition trim package.

Cool! You can try fewer, heck it may only take 1-2 of them. And smaller bumpers (1/4") might work too, but I haven't run a complete test. I got this idea from "trip dots" we use in wind tunnel testing to resolve issues like this. It only takes a small "bias" introduced into the flow to get...

Unfortunately mini-spares, aka "donuts", don't fit on many BMWs with big brakes -- not enough clearance. I don't know if the Supra has as large brakes as BMW M-sport and M cars, but it's probably ballpark. So for a lot of these models you have no choice but to go with a full size wheel/tire as...

Lookup the VIN in a BMW VIN database (several online).

To solve this problem on a budget, buy some self-adhesive 1/2" plastic "bumpers" and stick 4-5 in the mirror gusset area. That's all it takes to solve the problem. https://www.amazon.com/Scotch-Bumpers-Pack-Clear-SP950-NA/dp/B01N922DLO Square bumpers rotated to a diamond shape would probably...

Here are pics of the wheel/tire, and the setup in the trunk -- jack and wrench are inside the wheel, and everything is wrapped up in a tire storage tote sack. I added a couple straps to keep everything in place.

I am in the same boat with my M2 Competition, and I didn't want to depend on the tire slime (which only works in some situations and can mess up the tire and/or TPMS sensors). So I kept an eye on TireRack and when they had a suitable sized wheel and tire on sale for cheap, I picked one up and...

That is not the way BMW or Toyota recommends, and you risk denting the aluminum hood (read some BMW forums to see just how common that is). You absolutely do not want to be pressing down on the outer skin of the hood, no matter how gentle you think you are being. The hood sits on rubber...
