Have you called Donnie at lightning yet? You wont find a more helpful guy. He will definitely get you pointed in the right direction.

shock package.
What shocks are you running?

[racindirt8p]

Yes ive talked to donnie alot he's gott me alot better but car is still missing something. The shocks on car are all bilsteins 30-60 on both lf & rf . 20-80 lr & 40-40 rr

[JustAddDirt]

Are they an bilstein with a Schrader valve, or a standard old shock.
I would suggest you get with someone front Integra, Genesis, Fox, Afco.
The shocks you currently have are probably killing you in the slick

[racindirt8p]

Standard shocks 20-80 may not be heres some more info on car bars are set by degrees donnie told me car. #s are lf 600 rf 498 lr 713 rr 631 left is 53.7 rear 55 cross 49.5 bite 81 rake 5 in and springs lf 800 rf 750 lr 275 rr 225 thanks for helping!

I might add also car rolls over pretty hard.

[JustAddDirt]

under rail car or over rail?

[racindirt8p]

Over rail car

[racindirt8p]

Any suggestions? Spring changes bars or j-bar move? Thanks for any info

[JustAddDirt]

no adjustments will help a dead shock.
no adjustments will help if you have a standard gas shock with a lot of rod pressure, it acts like an additional spring.
my thoughts are shocks, because I have been there with what you are trying to do.

[racindirt8p]

Thanks justadddirt what shocks do i need? Thanks for input this is my first year in mods trying make car better and still learning.

I see a few problems, the main one being the shocks. Those 3060 shocks on the front are easy up shocks, which wont let the car steer thru the middle and make you have to break the car loose to turn killing the forward traction. The LR spring probably should be softened to a 225, and the 2080 LR shock needs a check valve put in it, if it is an off the shelf 2080 ( it doesn't have enough low speed in it to hold the car up )

Check your bird cages for binding. We had the same problem last year as the bird cage got warm the car would go away change the bearings in the bird cage and car was consistent again
