Off the showroom floor they are essentially the same, 11.5. I do not know of a comparison of two cars with the same build racing each other. In fact, they probably don't exist.

As I said above, I doubt I will lose a heads-up race to a Gen 6 ZL1 up here this season. Does that mean the 1LE is a better drag car? No, it simply means I have more power.

Although I can't support it, I would concede that in a 1/2 mile race between bone stock cars, the ZL1 should be a bit quicker, but no one races 1/2 mile.

I look forward to seeing your 60' times and that will answer the question. I did 1.24 at your power level. ;-)

What the Hell does ZL1Atlanta know anyway, he's only got the quickest 6th Gen ZL1 in the country. Maybe you should race him in his standard ZL1. I'm literally baffled by the fact that you think all those aero pieces and a road racing suspension has no impact on drag racing. By the same logic, does that mean that the standard ZL1 performs just as well on a road course as a 1LE? Should be the same if there's no difference.

We're not communicating well here. You didn't run a 124 in Denver at 8000 ft with a Toyo drag radial tire did you?

Why does my 1LE 60 ft. so much better than a stock ZL1?

Again, to repeat what I said above, the cars would have to be set up the same to compare how much better a ZL1 60 fts under the same conditions that a 1LE 60 fts, and that's not going to happen.

I didn't really build this car to be a dedicated drag race car. I built it to drive to the store, to drive on the road, to drive at the track and at the strip.

Agreed on variables needing to be the same, but my comments on the suspension being a limited factor comes from seeing this play out several times. Guys with drag packs, at better elevations, 15" conversions, and with similar power and weight, really struggling. This is my 5th year of drag racing a 6th gen ZL1 and a lot have come and gone during that time.

BTW - why not get a drag pack if you know you are going drag racing? You don't have to run it all the time of course, but you intentionally built a 1k RWHP car and plan on drag racing it. Obviously traction with tires will be your first limiting factor.

What drag pack are you thinking of?

17x10 with 305/45/17 MT ET Street R's. If you want to save on some weight up front, get 18x6 Welds with MT Sportsman SR's. Some require spacers and some don't (not sure what models are available these days).

I've got 17x10 beadlocks in the garage and I tried the 305/45/17 MT ET Street R's in both 2021 and 2022, but they wobbled down track. I have not tried them since I had the wheels aligned more neutrally last summer with less camber, toe, steer ahead, thrust angle, etc. I've never had a tire do that.

You will never run any decent times with a Toyo R888R. I would go back to the MT ET Street R's, its the most proven tire for drag racing and it always performs.

The only time I've felt MT ET Street Rs wobble is if they sat up for a long time and developed some flat spots, that will usually work itself out after driving on them for a little bit.

If they balance out good, it is likely the alignment. I have definitely gotten some that were out of round straight from MT and they replaced them.

Well, can I run a Nitto555Rii P305/45R17 drag radial on my 17x10 wheels? Don't see why not, but...

In a chat with Nitto just now, they said that I can.

I have also read that you shouldn't need to balance drag radials but I have always had mine balanced. Maybe I've been fortunate enough not to get a bad set that were out of round and couldn't be balanced.

Problem is that the 555R2 is a good drag radial that you can drive on the street and the strip but it doesn't come close to comparing to the MT ET Street R on the drag strip and with 1000+hp, you need all the traction you can get.

I'm sure they are good tires, but the ET Street R is a proven tire on this car and uses the same rubber compound as the Radial Pro's.

I have ran them unbalanced with no problems and other times it felt like the car was driving on rocks. I actually think unbalanced drag tires contributed to cracking the housing on one of my 10L90 builds as it was vibrating very hard and all of the bushings except the transmission were solid.

Good info, I will stay the course and continue to get them balanced.
