Default help with launching 1998 z28

Alright im a newb to all this. never been to the track yet but would like to master this before i go. I think i found out my cars stall is at 2200rpms. so when i get to it just punch it in over drive? ever time i try that i just spin all the way up to 6grand. i guess my rev limiter is protecting me but its still scary. so how do you guys do it? only way i can do it with only a little bit of spin is if i power brake it up to my stall point then hit it half way at first then go all out on the floor. if thats right. do i just keep my foot on the floor the whole time? or should i let off at any point? my uncle wants me to come to the track with him. i dont wanna look like a idiot spinning and running 14s in the ls1 lol.


also sorry if this has been posted. i kinda wanted to make my own with my own questions.

for one it sounds like you have the wrong tires, but you didnt say what you had so its hard to tell
street radials = in drive, brake torque to around 2800-3k, light turns green, dump brake
performance tires = in drive, brake torque to 2600-2800, green light dump brake
standard skinny tires = in drive, brake torque to 2200-2500, green light dump brake
its going to take some playing with to find the exact rpm you wanna be at, your first run try launching at like 2200 no matter what tires you have to get a feel for it, the track hooks way harder than a normal road, you should be fine, good luck

all seasons are crap for traction on pavement, thats your problem, launch low at first, and work you way up 200 rpm at a time until you find a sweet spot

I was worried about the samething before my first race. Nobody wants to look like a noob. First make sure you turn off your traction control if you have it. Then your going to have to find out what rpms work best with your car. Mine was right around 2000. When the light changes dont slam the pedal to the floor all your going to do is spin. The trick is nice even pressure. Thats what worked for me anyways. I took fifth out of 30. lost to a Z06 corvette by 1/2 a car but he did ended up winning the whole thing.

You should get some time to test and tune when you get to the track. Each track has different traction characteristics and they are usually alot different than the street. Also once you find that sweet spot you can shave seconds off your first run.

My first time down the track with my 66 Mustang GT was a really crappy 16.3 seconds. Before my next run I had an experienced racer come over to assist me. We played with my car in the parking lot and he gave me pointers on how to launch. I tried that my next run and hit 13.6. I didnt get another test run so I locked that in for my time. My next run I unfortunatly missed a shift and lost the race. Single elimination was the rules of the day.

Dont worry about not being the best driver out there, it takes time to learn how to drive the car. The driver that took home the money in my class was driving a Ford Tarus. She didnt have the fastest car but she was very consistant, down to the hundredth of a second consistant.

Also dont pay attention to both lights. In bracket racing you are racing your posted time. Your apponent may start before you but the lights are timed so that both cars should cross the line at the same time. You dont want to go faster than your time or you lose no matter who crosses first. You need to know what time you can cross the line each time so you dont break out.

Before we can help you with suggestions we need a few answers first.

What size rim do you have/ want.

What do you want your car to do? Cornering tires are going to be different than drag tires. What kinds of weather do you get in your area that you will be driving in. Things like that.

How much money do you have. If you got big $$$ then we suggest higher dollar tires... if you dont then we can find you an economical choice.

I just paid $875 for a set of rims and tires shipped to my door. The tires are an economy performance tire. They handle pretty good but not as well as say a set of Michelen's or Toyos would but for the money they are not bad at all.
