getting rr to stick

[sneaky56]

08 shaw basic setup with 200lb springs in rear wondering how i can get the rr to stick on slick......j bar is usually 1 inch above pinion to center on pinion

[sneaky56]

running 700-2000 pullbar spring and this is a quick change rear

How much rake in jbar and are you trailing the rr any? Bar angles in degrees and scale numbers would let people help better. Here is list of things to try. Good luck.

1 inch above pinion is 5 inches of rake...260lb driver....55lb left side bite with 50lbs in the seat. lrb bar 2nd hole up lrt bar 5th hole up rrb bar 2nd hole up rrt bar 4th hole up

as far as trailing goes....the bar lengths are supposed to be top 16-1/8 and bottom 14-1/8 well with those lengths the bc is 1/4 in indexed forward (ie out of the spring) so i adjusted the bars a little bit to get the bc straight up and down and rear end square....not sure if this is the thing to do

[powerslide]

is the car rolling onto the RR just not sticking or just not rolling on RR at all?

[sneaky56]

car gets on rf and rr fine just doesn't stick, brand new springs as well

[washeduptoo]

What are your wheel offsets on the rear and how much stagger? Have you tried lowering the rrl bar? Is your rear end centered side to side where Shaw wants it?

[powerslide]

try stiffer RR spring or lowering RRL bar.

Is this stop and go or momentum track? Entering on or off throttle?

[gun91]

Is it topping out the left front? If so I could be rolling over on the rr but then taking weight off the rr when lf tops out

I am looking at my Shaw setup sheet for your 08 car and your RRU bar should be 16.375 and RRL should be 14.250.... your looking at the LR bar #'s....you need you get off those LR bite numbers and get on the Shaw bite numbers.....
We have a 09 Shaw and we are tight on entry and have to loosen entry at almost every track we go to.......With your driver weighing 260# , what good is it to throw 50#'s in the seat?..... you need to scale out to probably 0 LR bite or 10-15#'s RR to get close to the setup sheet..... This is right out of the Shaw book.
Ls % 52.5 to 53
Rear % 55 to 56
Wedge or LR bite 15 to 20 #
all % are based on 180 to 200 # driver
If driver is over 200 #, decrease LS %
If driver is under 180#, increase LS %

Setup sheet is telling you what to do: no weight in seat, no driver in car during scaling.....base your setup on the above....
And when in doubt, Call Shaw

Just lower the rear roll center.

You need to scale the car with Driver in car, at 260 the bar angles will change a lot. Call Kevin and he will get you taken car of.
