Is my car a dog, or do I have sticky tires?
My car is an A4 w/ 2.73s. I tried to do a burnout yesterday for the first time to check if my posi was working. I turned TCS off, stomped on it from a stop and I just launched forward, no spin. I tried again with the shifter in 1st, same thing. Finnaly, I held the brake up to 2000 RPM and simultanioulsy let off and gave full throttle. I left maybe 7-8 feet of rubber (POSI works by the way). I was suprised how hard it was to break the tires loose. I stomped on it in a slow rolling turn and lit them up no problem and they spun all the way to 2nd. I have toyo proxies (245s) on my stock 16 X 8 rims. So I am wondering, is this normal, is my car a dog, do I have sticky tires, or is it just the gears. Thanks.

I think your car is working fine, unless I am out of it. I have an A4 w/ 2.73 gears, (not after today) and I had some Nitto drag radials on there with some ZR1 rims and the car would not hook-up real well. When I would take it to the track I would on the 1st run, but then after it would just spin and screw up my 60 foot times. Today I am getting 3.73s and some Hoosiers that are guaranteed to hook up. You may just need some new gears.

i got the 3.23's and i still have trouble, tried to break em loose about 3-4 times on the way home one night, i think once i got it to spin for about 5 feet. but i'm sure something is wrong with my car, the gas milage has dropped 2-3 in the last month. not sure y though

same thing here - A4 and 3.23's, won't break loose unless I really try (I can do it from a stall though). Also won't break loose from a roll but I would SWEAR I heard some spin going into 3rd@~75mph the other day
I think its a combination of low stall, low (numerically) gears, high torque peak, its set up for MPG, not for performance.

Good news / bad news situation. if you don't spin off the line, then you can launch cleanly and fast. If you're spinning, you aint winning...
Bad news is maybe you could use more power down low. Get a 3000+ stall torque converter and you'll be faster and able to spin the tires.

The stock torque converter coupled to the 2.73 is the culprit, I am running a Y3000 coupled to 3.73's and do not experience what you are describing.

I have heard of others having this "problem" before and its just the gearing. I myself have 3:23s and could spin em decently out of the hole stock and have toyos as well. Once the converter went in I cannot give anything near half throttle in first or full in second and not spin. What seems weird to me is that I never leave dark marks ever. Its always faint ones and its almost dissapointing.

The best way to find out if it's really a dog is to head to the nearest 1/4mi track and get yourself some time slips! My car with 3.23's doesn't really just light up the tires as it sits with pretty bald stock F1's but on a cool day I was able to get 2 12sec time slips out of 4 runs, so the whole spinning my tires thing really doesn't bother me.

Looks like you're putting money into show & not go. Want to spin 'em till the rubber falls off & be extremely fast? Look at my sig. I bought mine stock. Still looks stock but faster than any other car that has lined up with me.

when my car had 273s in it i could spin for about 10' from a dead stop. one reason you may not be spinning when you try to powerbrake is because the brakes are holding the back tires. i experienced this when doing my first burnouts at the track with this car. i tried to spot them up and it just torqued, so i let off the brake a little and they immediately went up in smoke.

You floor the gas, not the brakes......only use JUST enough brake to keep you from creeping forward....
