Best run was a 12.444 @115.74 it spun a bit and I have 10 speed auto I used the launch control. That was my first run it was about 62 out after that the temp dropped to 52 and I was fighting the 245’s and did not got any faster. But the good news is I picked up the 9.5 inch ss rims the other week that match my factory ones. Just have to find some rubber for them

Coming for my bolt on 5th auto as well I am very happy with my 6th gen. Bone stock very impressive and there is more there once I have some grip.

I have the 555R2's in the stock SS rear size 275/35R20. I like that they have them available in the exact stock size. If I reset my trip meter correctly when I got them a while ago I believe I have around 11k miles on them and they have just hit the wear bars, so the life is about what I was expecting about half the life compared to the usual UHP tire.

That being said I wish they had a little more traction (I guess we all wish tires would have as much or unlimited traction, I guess unless you want to do burnouts). Trying to launch with them I think only a few times I have been able to get almost no spin during launch. I haven't been able to test them on a track, but when I go to launch and stall up to about 1700 I get just a little chirp. However them being drag radials they have obviously had way more traction than any other street tire I have had.

I haven't been able to 100% conclusively conclude that a little spin/turnover/light burnout helps before launch but it seems it does. That being said its weird how random and inconsistent launching can be. It usually feels like when you think you see really good clean and flat pavement and you are feeling a really good sticky launch and the sun has heated the pavement, that's when you get the worst launches. And then it seems when you are least expecting any decent launch it just randomly hooks out of nowhere.

I want to try the NT05 drag radials since I guess they are supposed a 0 treadwear instead of 100 treadwear like the NT555R2's. It would be so nice to be able to put all the power you are making to the ground instead of wasting it spinning, but thats what we get for having rear wheel drive.

The tried and true to do that would be the ET street R on a 17. But then you’re not on stock wheels in the back

There is no tire that will dead hook with no heat in the tire....especially R compound tires. They need some heat to activate the compound per say. There is just no way around it. Even a Mickey Street R on a 17 isn't going to hook cold.

I agree, I have 2 sets of 555R2s. One set for Drag Racing and one set for the street. They need heat in them for sure and you don't have to kill them trying to get them hot, short smoky burnout in the water box and good to go. Mine hooked good enough to break an axle on a Vette that makes under 480 rwhp. I run a taller 305-35-19 for the street and 285-40-18 for the track.

I took my 21 LT1 to the track this weekend and was able to get a 12.1 @ 116 out of the car on the stock 245 run flats. I did a 1.85 60ft. Only thing I did to the car was let the air pressure down to 20psi.

Thats a great 60 ft time. Did you leave off idle and just mash it? and you really dropped pressure to 20 psi in the rear...

What size ET street R on a 17? 305 45 17? Yours dead hook on how much RWHP? with a 125-6 trap you got to be close to 500 rwhp.

[6spdhyperblue]

It’s the 275 and dead hooks with heat in them. I might be changing to the 305 for height for the a10. I want to see how the shorter 275 works first. If I had to start I would go with the 305 for the a10.

The car was never dynod, tuned at the track.

That is great info , thanks. You would think if the 275 hooks that good with a manual, they should hook the A10 car as good or better. The 305 45 17 is 28 inches tall, how short is the 275 tire? and are they 275 45 17?

[6spdhyperblue]

Thats right and 275 is 26 and change. My 16 car runs the short tire in the back but many others had the abs go nuts doing the same, therefore that mismatch in sizing isn’t recommended and run a 26 in the front. Thinking the 22 will not like it. Having the right height tire certainly has its perks.

I played with a 27 inch tall tall on my 2021 LT1 A10 and would get a an occasional very quick ESC light during the first 1/2 mile drive almost every morning? didnt make sense , but I would see the quick flash and than it was gone. I am going to try a tire/wheel off my 2021 corvette rear which is a 305 30 20 with the great michelin a/s tire . The stock 245 40 20 A/S on the my LT1 are pretty good for what they are, but never can get anything close to a dead hook. I am trying to just get a 1.8s 60 foot. I have managed 2.0 60ft with a 12.0 et, I know a 1.8s 60 ft should reward me a 11.8s pass
