The gearing on the GT is exactly what the car was intended for ... being a GT. Personally I love it... tall R&P means the car pulls hard for a long time in each gear taking advantage of the wide TQ curve. If you buy a GT... understand it's a GT (Grand Touring). Reminds me of my previous...
mark the coolant overflow tank with a pencil or something you can remove. Keep driving and observe. Look at oil on dip stick and make sure no oil/coolant mixing (looks like chocolate milk when that starts to happen). The bottom engine tray might be hiding coolant from hitting the ground.
So...
Start by putting it on a major diet... Major Diet. 4000lbs never be competitive in GT1, 2 and 3 (The serious race classes) The competitive cars (not just mustang) are <3000lbs w driver wet. Even that's on the heavy side.
Low horsepower light cars always beat high horsepower heavy cars...
You don't need to use them to understand the differences between a car that has a bigger circumference tires and the way it deals with heat and the one with the smaller circumference and the way they deal with heat.
What you saying is silly as if somebody needs test every single tire, back to...
Listen you asked the reason why and I answered. This is not opinion it's fact.
I haven't done any track time testing side by side to answer the question, but it's very clear why manufacturers do this.
If you read the LLM , the drivel spamming the forum I posted, then you know what the...
Because the Michelin blue slicks come in 18" primarily.. which is what they are running on the track.
The the rear tires (710) are so much taller than the fronts... it's like running a 2" bigger wheel diameter.
The GTD is a street car not legal to run in any professional class of racing. It's...
Lol... yep. BMW M's are amazing performance cars..... There's a reason why. So much is learned from the race track that trickles down into production street cars. The larger rears are just one of many...
Who is "we"? You? Are you the elected representative on this forum? Oh... you know what everybody here knows and doesn't know? Really?
You might learn something if you weren't so arrogant.
You asked "what's the advantage".
I answered by quoting LLM (because it was faster).
You accused me of using LLM to spew drivel and spam the forum.
So I articulated the advantages in my words, and used photos to show you how it's done in real racing and why... and showed you that the OEM's do...
The point.. which is all in response to your reply implying that I was some hidden LLM keyboard jockey spamming the forum with "drivel". So I had to spell it out to you and show you real-life pictures to back up what I'm saying.
Again...
There is a big advantage of having larger diameter...
It's clear you don't road race (actual racing) because if you did, you would understand.
I've been doing this for a very very long time and am speaking for direct experience.
Here's a pic from one of my former race cars. Look at the tires diameter differences. There's a reason why...
I don't know about drag racing... but road racing rim choice is very much determined by the tire availability (and rules). The best slicks are Michelins and they aren't making those in 20" sizes. They make them primarily in 18".
Nobody is talking about drag racing. And the diameter of the wheel isn't the issue... it's the differences in the diameters between front and rear and the effect it has on the handling of the car as well as helping to keep the driving tires from over heating. It doesn't matter if it's a...
Because I quoted it doesn't mean it's wrong or "drivel". Just a time-saver. And it's very much correct.
So here goes... larger rear wheels have more surface area (circumference) which means they get take longer to over heat (extremely important with slicks... and ultra high performance...
