Default Tires squealing down track

What adjustments would plant the tires more going down the track. I'm running [email protected], but it's spinning down track just ever so slightly. You can hear tires screaching down the track. I am running 4 link suspension.
I'll post a vid from last year running 8.59. I have more horsepower this year and it not planting it down track very well.

hey fallguy, very very nice, don't know if i can help, sure you know
quiet a bit with a car like that, but sometimes it might be just one
small thing overlooked but im sure the chassis is tight, your run is
straight. on horsepower their supernova did some test and it would
pull to the right rear like yours, they adjusted the front right and
rear right to stiffen up the shocks and then pushed the rear tire back
with the 4link on the right side, i don't know if the squealing tire
is the right rear but by the looks of your nice launch, it could be
torqing more on that rear tire, they also moved the battery to the
left side, but i know you see the pull on the car as it leaves, you might
analyz how much weight is mounted on the rightside, and im sure
if you have body mounts that are solid not to flex, might not help
but thats my 2 cts, good luck and go get em :wink:

also, i heard that front and rear motor plates can help with flex,
which distributes the weight, helps keep the body stiff, also
quick motor changes :wink: 8)

You might be at a point in time where you need a bigger wing on the rear for added down force. The stock one on the trunk lid is probably not long enough or is causing turbulence across the rear.

Nice run.


Just my .02,

thats right, a bigger wing would give you more down force, at that
speed there is down force, i think that would realy help :wink:

I'll have to check on the four link bar..but my 60ft times are 1.20's.

I've thought about adding a bigger wing...but was thinking maybe some suspension tuning might help.
