Well I was goofing around w/ my gf the other day (no not that kinda "goofing" around). She was driving her parent's es300 and I was in my 09 gts. Stopped at a light, she peeled out by accident, got scared and slowed down. So at the next lights, I decided to try again, but this time she didn't floor it but the G37S beside her decided to. This second run thou I managed to chirp going from 1st to 2nd. But anyway, the G37S kill me by like 3 car lengths, but all in all it was good. And yes, the car chirped.

Ok i've seen a few things here that bother me.
1. "Chirping" the tires is horrible for you trans
2. "Chirping" the tires is the proof of bad shifting (If your not grip your slip not faster grip and rip)
3. "Chirping" the tires Does not make you look cool

BTW someone, not me, should look into how many Ftlbs the stock clutch has. Sure i'd love a real tight grab but not for "chirping".

BTW2 Anyone have really bad tire hop? If its raining forget it, i loose traction and hear the tire bounceing off the road... shitty

chirp.

Yes, grip driving is better. No chirping/spinning isn't cool. But sometimes it can be fun :)

I've had tire hop a few times. Depends on the roads and where I'm revving when I let off the clutch.

Oh, I fully agree. It's terrible for your transmission as it takes the full brunt of the torque from the crank. It's always better to be on that ragged edge of the slip curve for the tires.. the point where they will almost start to lose grip, but just far enough where you get maximum grip and acceleration potential.

It's definitely wierd that they would choose to make the system act in such a manor where there is no full-on engagement of power when you shift quickly (subsequently dumping the clutch after a shift). The clutch may engage to the flywheel instantly, but the power slowly drops off, and then picks up again -- even with your foot firmly planted to the floor. I don't believe the clutch is slipping, since that would cause the engine to race into higher RPMs, rather than slowly decrease then pick up again. I am starting to believe they did this to save strain on the powertrain. Hence, it must be the ECU.

I'll get an instance of tire hop when I just break the grip potential of the tires, but just enough to cause them to break instantly and then grab again. Happens when I go off the clutch medium quick with 2-2.5k RPM in 1st gear , or in the rain as it slips and then the rubber catches tarmac again. Higher than 3k will cause more free rotation / squeeling.
