At a conceptual level, these types of products don't make sense.
It's a wash & wax in one.....so it's supposed to strip away dirt/grime while also leaving behind a protective layer? Strip away and simultaneously leave behind? Sounds like it'll do neither very well.
I can't take the writer seriously after her called them "hood flicks" 🤦‍♂️
Major click-bait title as well. These hood vent 'wickers' help pull air through the radiator by creating a low pressure zone above the vent. This helps a bit with downforce and improves cooling efficiency but it's not...
Could be because they are new but I don't know.
So looking at these, they are a DOT slick, 40tw. These will be a direct competitor to the Hoosier A7/R7, which are essentially the gold standard for competitive track day tires.
Even if these are faster/better/last longer than the Hoosiers, the...
Outside of take-off IMSA slicks, I don't know anyone who uses any Pirelli tire for track use. Not to say those tires you listed are bad, but I've never met or known anyone in the track scene to use that brand in general.
It's usually the popular 200tw tires, 3R's, or anything from Hoosier. And...
Fastest lap times: Goodyear 3R, Hoosier A7, (Hoosier TAP but still new so not a lot of info)
Fastest 200tw: Yokohama A052, Nankang CRS, Bridgestone RE71RS, BFGoodrich Rival S 1.5
Endurance 200tw: Hankook RS4, Kumho V730, Continental ECF
Fastest and cheapest: take-off Michelin or Pirelli slicks...
I think there's some sort of secondary pump to move fuel from one side to the other.
I assume the S650 uses the same tank as the S550 and there are several writeups on it over at M6G. Lots of fuel starve threads on high-G turns.
This is exactly why you need to ask people what their lap times are when they say they have no overheating issues.
I've seen this over and over - people claim they have no heat problems with a supercharger. Turns out they're just slow and not pushing the car.
Racers typically try to stay between 230-260°F. And that's with a lot of aftermarket cooling mods. It is difficult to do in a street car.
Oil additives begin to degrade at 270°F so really as long as you stay under 270, you are fine. That's not to say if you hit 290°F one weekend that your engine...
For track use, ditch the factory wheels and buy some 11" aftermarket wheels so you can run 305's.
If that's not an option for you, then I wouldn't go any larger than 255 on a 9" wheel.
These cars desperately need more tire in the front than what they come with so I would highly recommend...
