anyone ever barked tyres on a downshift?

[1fast03pony]

it happened to me i downshifted hard. what causes this? the sudden change in torque from gears?

 

[ZIPP0]

If i downshift at any RPM higher than 3 grand, my tires chirp.

This only happens accidently.

 

[Bone Racing]

yes very possible

 

[stangman]

many, many times

happens all the time Especially if i downshift to 2nd when im racing, gotta love the sound. Anyone know if thats bad for our cars or is it just the sudden change in RPM's?

Its not really good for the car (although a lot o f fun) but if its bad for anything, it puts additional stress on the whole drivetrain. it is just a sudden burst of torque to the tires that wasnt there before.

yes. Thats why some of my first mods were new flywheel, driveshaft, rearend, and clutch.

I've done that on the freeway. Freaks out your fellow motorists.

My tires bark on the 5-3 dowshift. And any other time i want them to.

Are you guys dropping the clutch??

I rev match and have no problem down shifting without making noise. Barking is tires is nice and all, but only when I want to

Yeah, you've got the idea. It's not like you're being easy on the car when you do it.

Yes i've done it a few times

I did it on a test drive when I THOUGHT I was in 3rd but I was in 5th and downshifted to 2nd. I thought it was about to blow up! I was doing 70MPH.

Rev matching takes more skill then just revving up and dumping the clutch to show off.

 

[1fast03pony]

yeah it sounded cool i think its gonna be the last time i do it though

...

I don't think it's actually barking the tires - I think the tires are actually sliding.

At least, that's what my mechanic told me after my first 5-3 downshift.

Any chance they could be sliding and not spinning?

Er, that's not my point, the original poster seemed confused about why it was happening... If you drop the clutch, course it's gonna happen.

usually do it in the rain :-/ but i guess its not really chirping, they just spin and spin and spin.......
