I Went to the Englishtown RaceWay Park tonight. like I have said in other threads I was shooting for a 12 second pass with my
manual 370z Base No Sport package so no VLSD 370z and got it.
I used 26x10.5 M/T ET Streets and I must say these are NOT the tires I will use again. I am not familiar with slicks or the "sway" they produce without skinnes. These tires are something to get used to. I did, to an extent, but with no doubt about it I was concentrating more on the "sway" than driving so I definatly did not drive as well as I could of. I ran the psi at 18 the first pass and Let off 3 different times and still pulled a 13.2 @ 101 ... Was easily my best launch too, which was weird because it was the first pass I ever did with the slicks. I let off a few times because I felt the " sway " ( strange side to side feeling the first run but got used to it when I realized its not all that intrusive, just noticable. Def something most have never felt going 70+ mph ) ...
I upped the psi to 21 and the sway was def tamed a good bit, and I was able to push the car pretty good. When I spoke to others they said the sway is a known thing and you get skinnies for that, etc. Most just advised me to get the M/T ET street radials a drag radial instead of the taller side walled ET Steet slick I have. A ET street radial a nice and light 17/18 x 10 would be perfect to keep the cars feel the most OEM while still getting traction.
But with that aside my first run was 13.2 @ 101 ... second 13.0x @ 106 ....
and third 12.954@106.80

The 60 foot is decent, and keep in mind this is on an open diff , and I did not pull the ABS fuse so I was not able to do stand stills. I simply went around the water with my M/T ET Streets and did a rolling burnout or 2. Def not ideal to heat the rubber, I need to look into getting the ABS disabled so I can at least light them up without abs or whatever it is that cuts the fuel and dis-allows a stand still burnout.
But even with being a bit nervous about the tire situation they certainly hooked way better than my stock rubber did. A few weeks back, my first 1/4 track visit I couldn't do better than a 13.5. With 60's of 2.2 + .
The ET Streets without heating them up got me a 1.945, But a 60 of 1.94 is nothing to be proud of with these tires. I could of done better. I'm hoping I can get a nice setup of Drag Radials for next time and sell these wheels off to someone who will use them properly, because I wouldnt advise to use them with stock rubber up front unless you are used to the experience. A turbo 350z was there with the same tires with stock rubber up front too and he knew what he was doing , so its not like its soooo scary, but a wierd feeling with the slicks causing the car feel as if its floating almost.
I will see better numbers with this car the way it is with just a new tire setup. I was always driving nervous and I think shifting too early and slower than desired because of this sway feeling. That is my guess why my trap is , almost, much lower than I expected.
But all together My 370z certainly did not disappoint tonight, it ran better times a bunch of srt 8's , I lined up and beat a Z4M that was Dinan'ed out. The guy was really cool, we bs'ed a little bit, he couldn't hook at all, but I have our race and slip I will post and you will see, his car never starts to catch up. But he needed new rubber. I drooled over this car, ill post the pics.
I raced and beat a New SS Camaro ( 13.9 - 12.9 ), BMW z4m very tastefully modded (13.7-13.2), a near stock 09 evo mr by less than one tenth ( 13.155 - 13.187 ! great race )
and got whooped by a c5 with bolt ons + 100 shot... that was my first run and at 1/8 of mile i was one tenth behind him but this is the run where I let off a few times because I felt the tires acting up. ( 12.135 - 13.206 )
