should the back end of my car sway?

[cb18201]

my friend has 4.30s in his cobra with an eaton posi unit, when he nails it in first or second the back end of his car starts swaying back and fourth till it hooks up, when i do this my car stays pretty much straight, i have a rebuilt T-lok in my rear end. if my car doesnt sway like his does this mean that im not hitting posi?

Has he taken off the rear sway bar on his car? A tire with a high side wall might also give this game effect.

check and see if your car leaves one or two tire marks when u burnout

idk why his car does that, im prett ysure he has the sway bar on. ill look though tomorrow. he has the stock size tires for his cobra, 245/45 same as mine. i figured it might be because his is hitting posi like it should and mine is not.

could be a traction/power difference too.

yea my tires are alot better then his, his engine is also a little more powerful since its a cobra

Well there you go, its torque difference.
