Just an update as far as 60' goes. These were the results I found with switching from cognito braces to an all seasons centerlink brace.
All season I have been running with cognito braces, and the lowest 60' I've gotten was 1.84. Well I replaced my cognito braces with an all seasons brace, and it dropped my 60' to 1.76. The track was like ice and even people with slicks were having trouble hooking up, one motorcycler ran over the median into another lane... Mustangs with slicks would peel out when they hit second gear, ect. Ambient air temp was 45* and the track that I go to doesn't do much to prep the track, it really sucks. I was thinking I would have worse 60' times but better trap speeds because it was so cold, but I was wrong and got the best 60' I've had all season.
I would recommend the all seasons centerlink brace to anyone, especially if you can't get a good 60'. I did notice if I left the line soft, I wouldn't spin but would only get a 1.8 60' and if I left harder, I would spin at first then hook up and get a 1.7, so spinning a little at first seemed to be the trick for that night.
Ended up doing a 1.76 60' 12.78 @ 103.21 which was an improvement over the previous pass with a 1.822 60' 12.861 @ 103.90, so it looks like the better .4xx of my 60' improved my 1/4 mile time by .11.
Here is a video of my 1.7 60', I'm racing Zach @ Starlite Diesel.
