How can you prevent spinning the tires through first?

[AudiSportB5S4]

As stated in the title. Just wondering if there are any tips. I was just rolling out tonight on a CLK55 AMG and spun the tires through almost all of first then chirped 2nd gear as well. LOL.

I have a 2000, so no ESP

I also have new (5K Miles) Goodyear Eagle F1 A/S...

Any tips on throttle control or just DEAL with it !

[Jung]

285 tires all around :)
esp

[highPSI-S4]

I wish i could tell you but since i'm only stg2+ i have to make a sharp turn and go full throttle with the ESP off in first gear

I somewhat envy you stage 3 guys

I heard about your encounter Mike. Sounded like fun. Maybe wider tires?

[Dr. Jekyll]

Wider tires will make the contact patch longer but narrower. So you may actually spin more with wider tires (all else being equal). What the OP needs are better tires. Ditch those Allseasons and get some sticky summers, and you should be all set.

[team_soy]

I have spun first and chirped second at the track with my all seasons.

Just launch it a lil lower with your current tires or just get some summer tires

[BastardS4]

Wider tires will make the contact patch longer but narrower.

WHAT?

Ugh. brain hurts now.


anyhoo. Get some stickier rubber, do the center diff mod upgrade to help with putting power to where the weight transfer demands it (the BACK).

And get some stickier rubber.




Finally, it wouldnt hurt to get some stickier rubber.

by not using shitty goodyear tires.

[MacDaddy]

I know you spent good money on your tires, but all goodyear tires are shit.

[BlackS4TT(Josh)]

Must be the compound of your shitty A/S tires... my car does mid 11's at 120+ in the 1/4, and even in the rain i don't completely break loose in a 1st gear roll.

the 1-2 shift does spin though ;)

[soccerplayer01]

how about lowering the tire pressure?

[gointoscott]

wow,

yeah I dont think i can barely get a chirp in 1st gear.

maybe dont rev it as high and it wont spin the wheels as easy? but i'm sure thats a given already.

that is some crazy power to spin an all wheel drive car that easy. I am jelous.

I probably wouldnt be driving that hard as much just for fear of tranny or clutch problems. have you had to replace either at all?

was that a serious statement?

better, wider tires, play with the clutch when launching till you get it down..if your coming off a first gear roll thats all tires u gotta rely on..i dont know if they have them for audis but i used to run traction bars on my fwd turbo si..they worked awesome

[exorcet]

single answer: stickier tires. don't need wider, don't need to get fancy with your launch...just get some 'summer wheels' with soft, performance rubber. You can do burnouts in 100hp civics with all season rubber.

[RolledMySTi]

I wish I had your problem and buy some real tires. You need a full summer max performance tire. Michelin PS2's kick butt.

The force of friction that the tires experience is
independent of the tire size, certainly. However, what a dragster does
not want is for the tires to slip - so the tires are spinning and the car
is going nowhere. What determines when the tires will start to slip is the
point at which static friction gives way to sliding friction. That force
must of course increase with the area of the tires, and so the bigger the
tires, the bigger the force you can use before you start slipping, and so
the faster your dragster can accelerate.

cheers

ok...

did you read the links? If the weight is staying the same and the psi is staying the same the contact patch will go from square to rectangle if you increase the tire's width. The total contact patch area will stay the same (since psi and weight are the same) BUT the contact patch will be narrower. Which is bad if you are talking in terms of straight line traction only.

[HighDesertAudi]

Dr. Jekyll is right.



P.S. Take a high school physics class and you'd understand.

Wow. Intelligent response. Very persuasive...

[Das General]

lol

wider isn't always better. it is all about contact patches and load (weight)

[BLACKa4QUAT]

Wider tires will make the contact patch longer but narrower..

this is true, i've been to racing school, and learned about the limits of adhesion, as long as the psi is the same, the contact patch will always be the same size. so as suggested, i'd go for better tires, maybe let some air out, it will let more tire contact the road. if people arent braking traction with stg 3, then something is up with your tires. since it seems your tires arent gripping in 1st, try using less gas in first, just a little less, until you can find the point where it starts slipping, then use a little than that. might take some time.

[Moe]

ok...

increase the tire's width. The total contact patch area will stay the same (since psi and weight are the same) BUT the contact patch will be narrower. Which is bad if you are talking in terms of straight line traction only.

The wrong use of terms has messed some people up. The term width always moves in a direction of side to side. Length goes from front to rear or the reverse.
I think a better and more correct way to state this is, " The wider the tire, the wider the contact patch. However because the square inches of contact does not change, the patch also becomes shorter".

How about learning how to launch? You will have years of fun fixing your car constantly if you don't. BTW that really shitty smell is your clutch not your tires.

[AudiSportB5S4]

holy shizit. i just go to sleep and get up for physical therapy and i get LOTS of replies....hahaha

ok one, i did not launch. as i stated it was a roll out, i can only imagine what the tires would do with a launch. maybe its just that 405WTQ

2. thats a good idea to lower pressure, my tires are kept around 37pounds.... what do you guys recommend ?

3. for people that track, what do you drop the pressure to when you track your car?

4. next time i buy tires i will consult those who tell me goodyear are shit

[AudiSportB5S4]

lol, again, it wasnt a launch, and you could actually hear the tires spinning then chirping 2nd.

the reason i ask is because, i want to go to the track to get a MPH in the fall without murdering my clutch setup. its only 10k old, and i dont launch it at all so im not going to start until i get a beefy clutch next summer. so i was just asking for tips like lowering pressure etc etc.

[AudiSportB5S4]

I probably wouldnt be driving that hard as much just for fear of tranny or clutch problems. have you had to replace either at all?

lol, believe me its like the fourth time doing a 1/2 shift. when i do it i say, how the hell didnt my engine just come out of the bottom of my car ? lol. I have upgraded however, (for whatever its worth) 034 Track density motor and tranny mounts along with Redline synthetic tranny fluid.

I've never had any tranny or clutch problems since the clutch job was done with stage 3 only 10k ago... and now if i have any problems im going to blame you since you mentioned it . no but im really suprised. all stock shifting components and i have a really smooth shifting car, i really baby the ever living hell out of the car so once in a month i like to remember why i spent all that cassssssh!

[RogueStatus]

isn't your car a TIP? better tires...maybe some drag radials for track use

[Allaidback]

what clutch are you running?

[YZracer]

Mike, I am running Bridgstone Potenza 960RE All season ultra high performance tires. I get almost no wheel spin in all conditions. Only when I launch the car for a split second is there spinning. If you want all-seasons, get the Potenza's. Hope school goes well for ya man, I'm lovin bein back down here at Tech.

ah ok. nice man. what PSI do you run in your tires.... by the way sorry about not getting back to you that week to head over to your house. this winter break for SURE have to come over. we can do some winter maintenance on the cars haha. good to hear you're having fun I move in Monday, start school tuesday the 2nd.

[AudiSportB5S4]

RS4 clutch. 10K mayybe. Next summer plan on installing VAST stage 3 clutch for launching

josh thats cus your cars a beast haha now make yours bros s4 a beast to and tell him to go full stage 3 haha

oh this is daniel with the nogaro blue s4 in pieces right now in wellington

Don't worry about it man. Winter break for sure!

I'm running 37psi up front and 36 psi in the back. I always felt the stock PSI of 36 up front and 34 in the rear was a little conservative. So i bumped up the front and back 1 psi. Then I wanted the front to grip more on cornering so I added an extra PSI to the back. Corners awesome with this setup too. Along with my PSS9's and rear sway, I get just a bit of oversteer with hard braking, and just slight understeer on corner exit.

I know i know, I shouldn't be worrying about slight PSI differences, it's not like I'm running Nitrogen in my tires, but any little bit helps.

[RudyH]

Wow. Intelligent response. Very persuasive...

I haven't been on the forum long, but from the few posts I have read from SpoolPastYou...

SpoolPastYou, from your highly scientifical research, please take an ESL course and re-read what Bob Erck said in his post from the link you provided.

I will put it in simple terms for you. "The real world is more complicated. Especially for tires that
are made of rubber. You want to choose a width, height, and tire compound
that gives the best friction for the duration of the race."

Yes I agree you can jump to the last sentence of his statement, but then you didn't read his whole theory did you? You only looked at one aspect.

A wider tire won't do jack if your rubber sucks. Some girls say the same about sex and like the kinky rubbers.

Chill out potty mouth. They are correct.

My stock wheels have stock looking tires that have a 160 tread wear. They don't spin. My all-seasons did though.

I had an article from a Bell Helicopter engineer with a handful of fancy degrees. He had built a gorgeous red 1965(6) Mustang with twin turbos and the works. He also ran a stock sized tire on the dragstrip. He and his high performance engineering cronies had mounted accelerometers in several cars and launched them with several types of tires. Their conclusions were that the difference between an open and limited slip was only a couple percent and tire size was barely larger than that. What made a relatively massive improvement was changing the tire compound. Running a narrow drag tire was much better than a wide normal street tire. Not only did it hook better, it had less rolling resistance which helped trap speed. The same works on a road course. I bet I could turn faster laps on a 195 width Hoosier A than on the best 245 or 255 width non-r-comp street tire.


In addition, dragsters are cool and make loud noises and all but their rules don't apply here. They get the tires to hook by destroying the clutch. The engine jumps to peak power rpm, the tires keep adding speed, and the clutch goes through hell. They also use very tall sidewalls and entirely different tire construction than any street tire. They start wide and soft and then grow to tall and narrow as they speed up. I've never seen a street radial do this. Comparing wrinkle walls to all season street radials isn't apples and oranges it is apples and a microwave.
