Well if you have a launch control that's about as good as you're ever going to get since it's taking the thought out of launching. And if you have to be in Sport/Track for that...not much choice there lol. I imagine that's more of a function of simply being in a "racing" mode than anything else.

Anyway, the short answer? Weight transfer! When the car launches forward, that initial weight transfer to the back tires is important - it's bonus traction, squishing the rear tires down as much as possible to maximize it. Going into Sport/Track (without launch control of course) is only going to stiffen up the suspension even more, making the car resist that front-to-rear weight transfer and thus, easier to light up the rears.

There's a fine line between too much and too little, but the Camaro is already a fairly stiff platform as it is. I'd want that rear as mushy as I could get.

Most of that Mush on my car with this suspension and these tires. I feel most of that at 30-40mph. Anything below that is a wash in terms of traction.

Which is why earlier I mentioned my goal is to get to 40mph as fast as possible without spinning the tires, after that I know I can absolutely put my foot through the floor and maintain traction.

Roll racing from that speed is fun, the car sits so far down on the rears when I hit the gas its surprising the car launches so hard from that speed without breaking traction.

For me from a dig, its a 0-40mph race, after that it is whatever the car CAN do with my fat ass behind the wheel.

MightyBoo is right about tour mode if you have MRC. I know I’m not wheels up in Tour mode but my car really squats more in Tour than when I’m in Sport/Track.

Plenty of us have tried launch control at the track with street tires, drag radials and you name it, you'll kill your 60ft times and the ECU is going to start pulling timing very quickly. Launch control is for the street. I've tried everything at the track with 400 rwhp to the tires to almost 900 rwhp. I don't know anyone that uses it at the track at all after they've tried it.

So you said you've run a lot of passes with launch control. Did you ever run faster in launch control, 60ft times, 1/8 mile or 1/4 mile. If you have you may be the only one I've ever heard that has.

You don't need to change anything on the car to go to the drag strip for the first time. In fact, you should change nothing. Go with the car that is familiar to you.

Don't worry about burnouts, which do little or nothing to improve traction on street tires.

Your first visit should be about learning how to:

* Avoid the water box so as to avoid pissing people off by getting water into the launch area.
* Pre-stage and stage the car in two separate steps, so you don't stage before the other guy pre-stages.
* Go on yellow so that your reaction time is not a clown show.

All of these experiences can be had in a minivan, let alone a bone stock Camaro.

It’s been back and forth. The first time I tried it I got the best 1/4 mile time I had ever gotten up to that time (12.1; 117 or 118 trap). Same session tried it again it came up way short. Bad 60 ft. I matched that 12.1 time in other runs on different days without using LC. A couple more times (different session) I couldn’t get it to take, so I was essentially in Performance Mode. I decided that for the amount of difference it makes, it’s not worth the stand on one foot, pat your head, rub your belly, cough twice process to engage it while lining up at the staging lights.

So laynlo, what do you suggest from a dig with 725 HP on street tires? I spin at 40mph on the highway doing roll races and used to love taking it to the 8th mile for some fun on the weekends.....I need to get the car out and see what works best from a dig but any help would be appreciated.

325's or 335's might help some for sure unless you value your corner panels

Not sure if you guys talking about having "no choice" with MRC mean that you can't get the suspension in Tour if you want to use LC. I haven't tried this, but it would seem to me that you can "lock" the MRC in Tour by going into the Infotainment settings screen and selecting Tour rather than the default commanded by the console switch. That would lock the MRC in Tour while the console switch can be used to put into Track (for ECU/TCU performance functions), then the double-tap to get into Competitive. Then LC is available, (but you don't have to use it), and the MRC should still be in Tour.

Edit: Non 1LE/MRC's can't do this which is what I have. :(

I'd have to manually launch in tour mode, but wondering if its worth the lesser throttle response

Unless gm took this out in 2019, you definitely can lock the suspension into any mode on MRC non-1LE cars. This is what I always did at the dragstrip and what I suggested (tour mode) on the first page o this thread.

Honestly you'll never hook 725 on street tires, so I'd look at getting a set of drag radials to run on the street. The Nitto 555 r2s actually get pretty good mileage. I followed a guy on Youtube that got over 11,000 miles out of his. Its tough on street tires with that hp, I did some logging with my old 16 SS Maggie 2650 and it was dangerous at 870 so I know where your coming from. I never logged on street tires again. Ran my drag radials and felt much safer at WOT but still sketchy on certain pavement.

Running drag radials will inadvertently add more stress to the rear axle with more grip, but it should be ok with the added stress no? I remember my old 10 bold on my WS6 trans am was a ticking time bomb.
