any others?

Thinking about experimenting. Let me know your experiences good or bad.

Thanks

For what? Grip?

Yep, want more grip to drop my 60' times.

A good set of drag radials. As far as treatments go I don't have any experience with them.

A trick I always use is to drop the tire pressure to about 20-22psi. In effect, it make the tire buldge out enough were you get more contact surface until you get going.

Burnouts help a LOT. Even in an AWD car. Drive thru the waterbox, lightem up for a few seconds, leave a trail of rubber, then drive back onto it. Hotter tires grip better and they stick better to rubber than bare concrete.

Wedge something into your rear springs so they don't compress as much. Weight transfer to the rear wheels does you no good. At the same time, run your times with almost no gas in the tank. You easily drop 50-75lbs in that ALONE.

I'm giving away too many of my secrets now...

done it. don't want to drop to much or the tire will cup in the middle and decrease surface area.

done it. although I hear gains are minimal with street tires, but it does help clean them off.

Already in the works. Did the 1/8th tank thing too.

so what are your other secrets?

They have to do with Taco's...

A little cupping is ok remember when you launch weight transfers to the rear taking pressure off the front wheels. Less pressure on the tire will flatten out.
Also as the wheels accelerate (spin) the tires will expand.

Ahhh... <goes out to dump taco sauce on wheels>

^^^ Perfect! ^^^

Anyways... After 100's of FWD launches with my car, other than perfecting the launch itself, there really isn't alot you can do with street tires. Short of making sure they are clean and hot as was already said. Lowering the pressure til they slightly cup is also a help, but even that will only gain you maybe a couple hundreths on normal street tires. They are just too hard of a compound to really get sticky and flex like you need them.

Getting to 2.0x and quicker are going to either require a crapload of HP or Drag Radials.

Razor blade the gripes off to make a slick.

Take the tire off the wheel, set the tire in your back yard away from EVERYTHING, spray ether or starting fluid in the tire(lots), and toss a match at it while hiding behind something such as an overturned table. the resulting explosion typically blows the tire 10-25 feet in the air, and breaks the metal in the radials. this allows the tire to be much more flexible, and gives it more surface area to grab with.

After step 2, get a pan, get bleach, fill it about 1 Inch up with said bleach, and set up a small motor to slowly turn the wheel in bleach. (think rotisary chicken) leave the tire rotate in the pan for a night. re-mount the tire on the rim.

The bleach softens the rubber compound in the tire and makes it grab much much better than a standard off the shelf tire.


Doing the above will ruin your tires for daily driving. and shorten the life of your tires to about 3 or 4 track visits.

Have fun!
