Why anyone would even consider running a car, let alone the Supra, on summer tires in the winter is beyond me.
The word "summer tires" should give a clue.
I guess dealers handle it very different and it also might vary from country to country.
First sports car i bought the dealer let me had a demo car for a week. The other car I bought i had a demo car over the weekend. No questions asked, just here is the key. Don´t wreck it.
I think it is a bit more to it than that;)
"The IBS is a mechatronic component for monitoring the battery condition. The IBS is secured and connected to the negative terminal of the battery. The power supply for the IBS is fed across a separate cable. For data transmission, the IBS is connected...
For me it is a case of rather safe than sorry.:)
I know a lot of people are charging at the battery with no issues, but I am going to trust the people who developed the car and wrote the manual.
If they state to only use the terminals under the hood there is probably a good reason for it...
Sure you don't want cables dangling under the hood if you intend to have it there while driving.
However it has been well documented in different BMW forums that it has its risk hooking up a charger directly to the battery. You could blow out the junction box and that will cost you +1000 dollar...
Does anyone know if these are sold somewhere in Europe?
ZL1addons state they ship worldwide but I have been unable to get any response whatsoever from them. Apparently, their customer service is a bit lacking from what I have read elsewhere.
I would go for the 2020 and use some of the saved money on aftermarket parts.
So far the 2021 cannot be tuned and those extra 40-50 some hp can easily be added to the 2020.
With just an ECU tune you get around 90 extra hp give or take which means the 2020 will have 40-50 up on the 2021.
Some...
