Default traction issues

i just purchased my first car, which was an 85 corvette greenwood, with some medium engine modifications(cam, chip, intake exaust, etc.) and so far, the only real problem i have with it is that i cant hook to save my life. at anything over 1/3 throttle, about 1800 rpm, i just sit and spin the tires. are there any things i can do that will help me out with traction, or is it just a byproduct of the model? almost forgot, it has the 4spd auto in it.
thanks

a small amount of spin will keep your rear from breaking parts, But if you want the car to hook, just get a set of M/T or BF Goodrich Drag Radials and problem solved.

Default traction

In my days of stockcar racing we would use something called tire softener, some would spray it on the outside of their tires,some would soak their tires in pan of this,rotating them for days. The way I would use it was add some of this on the inside(14oz.) and rotate the tires for an hour,we had a tire durameter that would measure the softness of a tire(softer means better grip). I would recommend spraying it on the outside as it would expand on the inside of the tire causing air pressure to grow.A good parts cleaner in a spray can with Tyulene works good,just spray some on the tire and it kind of melt. A word of advise use caution!!!!

I'd start with some new tires. How old are the ones that are on there now?

Default Cold Weather May Be Issue

When it is cold outside, my tires will spin on the pavement and not even screech. No traction at all till spring time.....

when u talk about hook...do u mean at the strip or just on the street?

tire age could be an issue...maybe they are over inflated?

cold weather could be it too...

my 85 4+3 will do the same thing...you can't really just stand on it, but you'll go nowhere fast...try a gentle roll into the throttle until the car gets moving...then mash it...enjoy...rinse and repeat

ok...and you probably have the standard 9.5x11 in the front if they are the ZR1 style wheels...there aren't that many tires that are the same tread pattern in both sizes...sumitomo HTR-Z are nice tires...check out tirerack.com....best tire for the $$ as far as i am concerned
