why do my Z always lose grip?

johnsonhuang · 11-02-2009, 03:30 PM

When I race from a dead stop with traction control on or off it always slips. I have a automatic. i always lose a lot of speed when its on. but when i turn it off my car slides around like a snake. how do you automatic Z drivers stop the sliding and launch off correctly?

Upgrade to a Better Diff. Prevent the car from Peg legging

Moved to Drag forum where there's lot of threads on launching the Z

What model Z do you have? Does it even have a LSD?

Consider wider, stickier rear tires.

i got volks sf challenge 19's 9.5 in front and 10.5 in back. its a touring so it must have everything. when i turn off the vcd it slides like a snake. when it leave it on , the tires lose traction and cuts off gas and lose tons of speed. how do other Z drivers go off perfectly?

don't use the pedal like an on/off switch?

I have not driven the auto Z but it sounds like you need to be more gentle on the gas pedal.

Duh...dont you know...it will ALWAYS slip around because.....

Either:

A. You're mashing the pedal to hard and losing traction, or
B. Your tires are bald and can't get grip

How long have you had the tires?

What kind of tires? What size?

I have 10½" rears with 285 Michelin PS2 tires and find it difficult to get them to break loose. As others have noted - bald tires, hard rubber, too much throttle to quick, all of those work against you.

johnsonhuang · 11-02-2009, 05:05 PM

it has 50 percent left. i floor it when im about to start. ive driven a m3 smg and when i floor it i still get traction. maybe im smashing on the gas pedal too fast when i start. any tips?

imsonastie · 11-02-2009, 05:06 PM

its because our cars have no weight back there, i recently bought some toyo proxie r1r's and i love them. i used to spin 1st and 2nd, it holds up now and just chirps the gears, 3rd chirps too. they arnt very expensive.

johnsonhuang · 11-02-2009, 05:06 PM

i got nitto gen tires.275/35/19 245/35/19

03threefiftyz · 11-02-2009, 05:14 PM

Sounds like a case of bad tires and poor track prep.....What is your best ET and 60'?
