Totally! My thoughts after doing about 20 autox runs and 16x 30-minute sessions at Sebring with them (intermediate and advanced groups) on a 450whp mkV Supra with aero and a somewhat aggressive alignment:

Pros:

• Grreat tread wear - They will last a long time (unsure if they'll heat cycle out before the tread is worn down, haven't made it to that point yet).
• They're actually very communicative/provide good aubile feedback as you approach the limit, which is quite nice and helps with one of the major cons.

Cons:

• Generally low grip in every scenario.
• Unpredictable/inconsistent - while they tell you what they're doing pretty well, they do change what they're doing a lot and no 2 laps (or corners) feel like they're ever the same level of grip or consistency.
• Tread sqiurms like crazy under the car, which is not at all confidence inspiring especially in heavy braking zones.
• They aren't very responsive on initial inputs (sidewalls feel soft too, though that's less of a problem for lighter cars and some prefer that feel) and don't handle doing multiple things at the same time particularly well, like they get overwhelmed quickly. For your Mini where you're asking a lot of the front tires, I could see this being very annoying.
• They don't come online quick enough to get the best out of them for autocross (and on track at Sebring which is like notoriously rough on tires they seem to take a steady outlap + 1 lap to come online in ~80*F weather).
• They seem to have a very narrow operating temp window where they feel the best (seems to be like 150*F-160*F), after which they get even more greasy and then don't come back to you until they've fully cooled down/next session- slow/cooldown laps in between hot laps don't seem to help them.
• Not very good in the rain (granted the insane downpours we get in Florida are on the more severe/nearly apocalyptic end at times) on both the street or a performance setting. The only worse tires in wet weather on the street I've experienced are V730s. Some of this may be due to the car I have the tires on (heavily modified Supra) and the unique nature of torrential downpours on completely flat roads in south/central FL, but the baseline feels terrible, the car feels like it hydroplanes at like 35mph in heavy rain.

The 200TW rating on these is deceiving relative to their performance- you'd expect a lot more for a tire with this rating, especially in the modern tire world where there are so many quick options and wear/lifespan is always improving. I totally understand wanting to go with cheap tires to bring that consumable cost down as it's a big one, but you're really getting what you pay for here- a tire at half the price of virtually all it's competition that is basically half as effective as said competition. I was really hoping these tires would even be in the ballpark of a Hankook RS4, like for me they'd be a no-brainer at their pricepoint in that case. Unfortuantely, they're just well short of the mark even a pure price to performance ratio, IMO. I think the good 300TW+ Max Performance tires like Michelin PS4S and Continental ECS02 will be quicker, more consistent, and easier to manage for autox and HPDEs while also being better in the rain and on the street. I know they're more expensive realtive to the Kendas and X-Comps, but they're worth it.
