thanks for the help go 24

i have other questions to. if anyone is willing to help. this will be my first year, and the car is being sponsered to me. what should i shot for on a tacky 1/4 mile track with good banking. looking for spring rates/ride heights and bar angles. like i said i know the car is out of date. i just dont want to look like a nut on the track.

im building a 412 with all eagle assymbly stought roller cam. not sure on heads or carb yet. how much of a disadvantage will this old car put me at? thank you.

I'll try to help ya as much as I can. If it doesn't have it already you need to add the lr behind shock mount & birdcage. I would also contact the previous owner if possible...they'd know more than anyone what the car needs. In the mean time I can give you a baseline which is typically the same for most 4 link cars and then you have to adjust from there....I also recommend buying the NEW GRT/Steve Smith book on late models.

springs
lf 500 rf 400
lr 225 rr 250
shocks (short banked track)
lf 7400 rf 7500
lr 9400 rr 9400
lift arm
7300 shock 300 spring 32in out (short track)
*use a 6th coil w/a 400lb spring
*don't use a 90/10
J bar
8in rake, middle of pinion
Percentage
53% left 55% rear 52-54% cross 150lbs wedge
front end
RF 3.5 + caster
RF 4.0 - camber
LF 1.5 + caster
LF 1.5 + camber
1/4in toe
Rear 4 link bars
Right/left top bars 3 holes down from top
Right/left bottom bars start in the center
*ballast should be in the tunnel of the car-near x frame.
Raise the motor 1in (spacer) if your using steel heads/block

I think that about covers everything, remember that's just baseline and it likely will need to be adjusted.

Granted it's an old chassis but if it hasn't been abused or wrecked hard it can still be competitive, you'll need the seat time as much as anything and your better off running around in the back trying to put together consistent laps more than anything. Generally a chassis that was used as more of a limited late model will last longer compared to a super late model because of the flex their put through with the high horsepower.

I got to looking at my notes last night sc1racing and I told ya wrong on the front shocks, for a high banked short track I'd use a 7500lf 7600rf.

i raced an older shaw for a couple years. it was 4bar both sides. this car was very smooth handling, showed me alot of great nites. i was underpowered. so bite was always great. id love to have another shaw late model.
