all this is regarding the first 2 generation miatas. the car that is smaller, slower and hundreds of pounds lighter than the frs.
i still dont know why you bring up slamming cars. literally zero relation to the argument at hand. or hydroplaning for that matter, might as well just put some snow tires on the car. or wait, what happens if you go off a bridge, replace the tires with rudders. you want to be safe in the lake dont you?

HE MAKES RACING WHEELS!!! NOT STREET WHEELS!!! Again, when you are racing on a controlled environment like a track, there are different factors at play. First, many of the racing Miata's have modified engines giving them 300+ hp. Secondly, you don't run street tires on those rims -- you run stickier racing tires which changes the geometry. Again, you don't seem to understand that the choice of tire/wheel combinations is very complex. On my track Porsches, I used wide wheels and tires, but not on my street Porsches which were close to factory specs.
I don't know how to get this through to you, but the best tire/wheel combo for the street is different than it is for racing on a track. You don't know when it is going to rain, so on a street car, hydroplaning IS an issue.
So when DSPORT modified their Miata, they wanted wheels and tires that were aggressive, but could be driven on the street effectively. The tire they chose was a 215/45/17. But that Miata already had modified suspension and was lowered. And of course, the main reason, at least in my case to own a BRZ is the fun of driving it. Here's an interesting article about driving fun you should read:
https://arstechnica.com/cars/2015/09...da-mx-5-miata/
Tirerack has a video about running three different tires on the 86 which you should see. The one they liked best was not the stickiest one.
Again, this is a complicated issue and you have to decide whether you want a car that is good on the street, is good on the track, or is one you want to look much faster than it is, i.e., extra wide tires, lowered, big wheels, etc. I've decided I want the best street car with the best ride, and good performance. The OEM Primacies do slide too much and I just don't like polished wheels on a car that has little other chrome. So I am doing a little bit about looks, but keeping it fairly close to stock. You've obviously decided otherwise. I cannot really rationalize, from a performance perspective, changing much from stock, except that I just don't like that polished look and the OEM tires slide a bit too much for me.
By the way, which BRZ do you drive on a daily basis from which you have all of this experience? You can have the last post. I'm done. I hope some of the issues mentioned here will help others make their own decisions. Have a great day!!!
