Looks great...thanks! Those are very clear, telling pics...no fear about getting 20" wheels now. I appreciate it. Not to mention the tires are significantly cheaper than 19's. What I was referring to before was a generalization with 19" wheels as opposed to your concern of having 20". When it comes to how a car looks with aftermarket wheels, it really depends on a combination of the offset, size and width. A combination of the three as compared with stock specs will either give you more positive or negative camber and therefore can change the wheel gap. Before you make your purchase, I recommend learning how the dimensions of your setup will change based on the wheels that you want. This will give you a better understanding of their affect on your wheel gap. The pics i've seen so far have been fine so I doubt there will be a huge change but nonetheless, your best bet would be finding a picture of a stock suspension car with the same sized wheels and offsets that you want.
The most loop-the-loops in a Hot Wheels track is 10 and was achieved by Rohan Dayal and Rahul Dayal (both India) in Mumbai, Maharashtra, India, on 7 April 2021. It took Rohan and Rahul three days to build the adjustable angle wooden platform and assemble the entire track of 10 loops over it. Two people were involved in the project. Rohan Dayal and his younger brother Rahul Dayal. "Testing was initially with few loops and as we increased the loops and the length of the track, the project became challenging. Since the track became long it needed to be supported on a firmer wooden platform. The longer the platform, the greater was the weight and bending in the center. This needed strengthening of the platform. This was the initial challenge." While testing the brothers found that the journey of the car through the loops depended greatly on the angle of the platform. To facilitate variable angles they had to construct an adjustable wooden leg support. By adjusting the leg support during testing they arrived at the best angle which gave them the breakthrough that they could achieve the target. The project cost approximately INR 3500 ( approximately £35). The cost was less as the brothers already had collections of Hot Wheels cars and track and only had to purchase the remaining missing track pieces. The plywood used for the platform was upcycled from scrap. There were a numbe rof challenges faced by the pair. As the number of loops increase, the project became challenging in terms of scale. The length of the platform, it's weight, and height also presented difficulties in handling. The speed of the Hot Wheels car increases as it descends from greater heights causing the car to lose balance. Despite all these difficulties the pair think they could attempt to increase the loops by a further one or two in the future. "Since a young age of around 12 years, I would try to do small projects like making a wooden toy car or cricket bat. Later as I grew I would do some small household repair works. For all this, I would use my Dad’s tools. As a child, I liked playing with toy cars. I would make my wooden toy car and make it slide on sloping surfaces. During this time I was gifted with Hot Wheels cars and tracks which came with super smooth cars and steep sloping tracks. Soon I had a good collection of it. Recently I came to know about the Guinness World Record of 8 loops and decided that I can better the record. The Guinness World Records titleholder would be the best thing I would have ever got. It would also mean that records are an inspiration to do better and create greater records. It would be a proud moment for both me and my family."

Ditto for cars, said Barel, although implementing the SoftWheel system in planes and cars won’t happen overnight. “Plane designs have to be approved by the Federal Aviation Industry in the US, and implementing changes in the automobile industry takes time. But eventually, both industries are going to adopt our design. Until now you had to choose between comfort and efficiency in wheel design, and now, for the first time, you can have both.”
When one wheel moves up it pulls up one end of the bar and the other end pulls up the other wheel, keeping the car level.
