LR setup

[lindsey97]

I ran a 90"s shaw car last couple of years with a 602 in it and fought the same problem. We dropped our bite down to the 0 to 20lb range without driver, with basically the same setup. Car started working well then, but I think you will find it burying the right front frame rail in the ground. I think you will need to go to the 400 or maybe a 425 rf spring. Even though you take the static bite out, the dynamic bite will be there with the heavier rf spring.

Mess your ride heights up? When you take the turns back off, your ride heights will be exactly back where they were(if not something is bound up). Rocking up the left side is one of the quickest ways to wake up a flat car.
A lot is going on (to help your problem) with this seemingly crude/simple adjustment.

im just going to try leaving the shock and spring we have on it. maybe dial up a little more wedge and call it good for our next race which is June 4th.

alright guys. ran this weekend and car seemed to be the best it had been. we ended up running a straight 4c&r on the L and R with a 250 on the LR and and 200 on the RR. Ran a straight 5c/r 500 LF and 4c/6r w/ 375 RF. ran about 115lbs of wedge.

this being my 3rd race in a LM i did pretty well. ran 5th in my heat and then 14th in the feature. still need to work on my consistency. seem to have 2 or 3 good laps then a bad one then 2 or 3 good ones and so on. from heat to race this week all we did was scrape the mud off the car and go for the heat.

what effect would there be on the car if we just hooked up a 6c0r traction shock on the front with 125psi and changed nothing else?

Possibly loosen entry if driver is letting car slam all the way down. Car should be easier to drive tho.
AND Tighten on throttle.

quick question i know on 05 shaw there are 5 adjustment holes for the 4bar is it the same on your 04 then check and see if your jbar runs straight or forward from frame to rearend (causes a roll issue) does it have the twm shaw cages on it?

[rubbinsracin]

yes we have the twm cages on it. and the jbar does go very very slightly forward when at static if i remember correctly. what kind of roll issue does this cause?

[racin29]

seems to bind when the car is flat have to "jerk" the car to get it to roll over couple options are to cut the frame bar out and move it ahead 2 inches or find a clevis style jbar bracket, this is what i chose to do, mounts the bar to the side of the frame mount this will free up the car a bit after we put the other mount on the car started its roll the way it is supposed to like i said before doing was having to set the car hard to get it to go, if your having problems finding the bracket ub machine makes one thats what i used

[rubbinsracin]

ic. well we were just under the car cleaning it the other day and i will climb back up under there and see if we have any rubbing or anything that looks like it will cause any bind. when you put the jack under the middle on the left side and jack the thing all the way up. there is no rubbing or binding that takes place as we checked that last week when we were worried about beind stuff. but i will double check for binding/rubbing that could be caused at speed by additional roll steer caused by turning....but i doubt we will see anything as the RR should move backwards...be it however little when the car rolls moving the bar away from any possible bind/rub

[racin29]

im not going to say there is a physical bind on the jbar, if i remember correctly there wasn't on my car, but there was a momentum bind, if that makes since if you get a chance to snoop this weekend look at some other cars a see how the bar is on theirs, i just know shaw has things very tight back there on these cars and the other mount is cheap $20-25 thing to try to get the car to get up on the bars easier, also are you using a chain stop or letting the axle ride on the frame on the lr

[racin29]

what size tires and offsets are you running

[racin29]

for 29racin, nice name, your loose middle problem is probably because of your tight entry, first things first, loosen up your entry raise rl bar, depending on where it is, put a 400 on the fr, probably what i would do, put heavier lf spring in, will only change entry

[rubbinsracin]

i will take it into consideration. we have a good jbar under it with good free heims in it. its goes up and down pretty well so i think were going to keep the car very close to where it is at now and continue to make small changes to make it better.

i do have the throttle extened out all the way it can. i have a ton of throttle travel. i just talked with my dad. who stores the car during the week say that the rear breaks looked like they were in need of being bleed as the gauge was needing to be pumped before the rears showed anything much for pressure. that could be part of why the car felt tight going in? we will get them bled and go from there.

also, would it be better to run a straight 4c/r with a traction shock or run a 7c3r with the traction shock?

[racin29]

that is driver feel most guys run a 6/2 behind, i would look at other areas first tho, shocks can win races yes but they are only going to do that to a second or third place car keeping it simple learn the car with basic shocks to begin with befor you get to crazy because they can also loose you races and set you back weeks of tuning

[rubbinsracin]

i think that is what we are going to do. little things. we have seen in other classes we raced, big swings are just that. one time you hit a homerun but you strike out the other 99 times.

to answer your earlier question, that i just saw, we run all 14" wheels with 5" offset

92s on all but the LR which is an 88. we usually set up for around 4.5" or 5" of stagger. we are required to run the WRS2 D55s with NOTHING done to them at all EXCEPT running some sand paper on them to put a scuff on em.
