Loose in and on throttle until car gets straight

[Flyin Iowan]

LF 550 RF 600
LR 200 RR 175

QC jbar top on pinion with 5" rake

1/4 lead in LR

18lbs bite
52.3 left
57.5 tail
1 1/4 stagger

LUB 24 deg
LLB 4 deg
RUB 18 deg
RLB 0 deg


car doesnt feel like it transfers to RR unless there is some tacky patches in track for it to get ahold of

car also feels like it drops on LR and doesnt roll on RF if im in traffic and have to back off early. Would jacking up LR and lowering RF help this?

Would dropping jbar 2" on both sides, going to 550 RF and 200 RR be to much of a swing?

Also, running on American Racers and this is a slick little 1/4 mile track. medium banked.

Try the Jbar first, maybe not so much split 3-4 inches. If not enough, move the LR back that 1/4 inch and try it. If still not enough, move RR forward. Reducing stagger would also help, but you do not have alots now.

Air pressure ???

LF 11 RF 15
LR 10 RR 15 Boubin Tire told me 15 on RR

[powerslide]

i think i would try reducing trail or stagger. and moving the jbar down 1in on each end.

[washeduptoo]

Where is your jbar on the pinion again, I'm misunderstanding what you typed?

[Flyin Iowan]

about 1 1/4" about pinion on a QC


Also would leaning the RR spring inward help with weight transfer?

[washeduptoo]

Try running 1in above center of pinion. Have you checked the lf shock to see if if is rebounding properly, had that problem a few times. Good luck.

[Flyin Iowan]

shocks are all good. with the plate i have on the QC i would have to move it 1" so ill only be slightly above pinion

[washeduptoo]

Your talking above center of pinion correct? We've run ours at center and below on a qc with 6in of rake but that was too much rake, running a short panhard bar now and its working well for us. Good luck.

What shocks are you running?

It seems obvious but you can do an 8-2 or 9-1 on the LR. Tie down shocks on the right side of the car...???

[not clamped up]

Do you have a brake floater on the LR ? It would help in traffic, Schrader has 1 on his car along with most everybody else thats fast,and when all else fails Z-link the Right side it won't be loose anymore,justa a couple other things you might think about.

Are you leaving the spring in front on bc or putting it back on top?

[not clamped up]

In front on the BC.

[powerslide]

is schrader in a skyrocket or a impressive? if skyrocket is he on the liftarm?

[not clamped up]

Impressive with a pullbar in the pics I could get a good look at.It is a overrail and his old car which is for sale on stlracing.com with pics is an underrail,Kenny Wallace's new car won at Eastbay with a 5th coil.

noticed on this car they did not paint the chassis kinda different. the two kenny's have found something they're both fast in ther impressive cars/pro shocks.
