I run a 3link 15" c to c bars lr. in frt. rr. on top and was wondering if any guys are out there pourin the bar angle to the lt. rr. like say 18 degrees and rt.rr. 10 degree and puttin a stiffer rt. rr. spring(225) in than lt.rr.(175) to help the car get in like a bandit .......the big bar angle in the lt.rr. drivin the car off with decent rt. rr. angle for its bite too . I would also have to drop my lt.rr. bite because of the increase in bar angle (200lbs. bite) but I was just thinkin about runnin pretty good bar angles in both sides but still havin a decent more angle in lt. than rt. .... that both sides would get increased bite and maybe be better on slick and heavy ? I worry wether the rt. rr. would get much body roll and if not ...pour the panhard bar to it and if the big bar angle would give out too fast on the straights ? Does this idea even sound feasable , guys runnin this deal , or what do you guys think ? Thanks

I had the same thought a couple weeks ago, but I also thought about running reverse stagger on the rear to help tighten it up when you get back on the gas. The stiffer RR spring should help keep the body from rolling too much. I'd really like to know if this works, but it's starting to look like I'm not going to get my car out of the garrage at all this year to find out. (just got laid off again! 3rd time in a year & a half) The Cup boys are drivin' off the RR more than ever and I thought it might be possible to start doing that on the dirt. If you try it please let me know how it works. It may take some 'sparementin to get it dialed in. Good luck!

If you're going to put the car up on the bars that hard I hope you are running a glass smooth track or you'll shake your teeth out. It will be like having no springs at all. I know you're not talking about running real heavy RR weights, but I do know of one guy that does(in the range of 150lbs or more RR heavy). He's real fast on heavy and **** on dry slick. He also blows out a lot of RR tires.

What if you put the rt. rr. link down to about 5 degrees , lt. rr. at 18 degrees , 225 rt. rr. spring 175 lt.rr. spring , and lt. rr. bite at maybe 75 lbs . I know this would be a driver preference deal but I jus started thinkin if you could get in like a bandit with the rt. rr. spring and then had the big bar angle on the lt. to drive you off that this might be a good deal ? I think the lt. rr. bite is what I would have to adjust accordingly for my feel . I'm use to runnin 200 lbs. lt. rr. bite full of fuel with me in it 54 % lt. , 54 % cross , 60% rear , and frt. wheels even . I have been playin with the rear springs like 200 lt. and 225 rt. .......175 lt. 200 rt. ......with those figures above though and 10 dergree rt. and 12 degree lt . generally lacking gettin off a tad when these springs are like this on the slick . Any ideas on this or s**** it .......car gets in like a mother on the slick .....that's why I was wonderin about pourin the bar angle to it in the lt. side to compensate for the heavier rt. rr. spring that helps me gettin in ? Might even have to pour more bar angle to it on the lt. than 18 degrees ......car doesn't get on the bars very much now . Thanks

if your getting in hard on dryslick now that is probally your problem. enter slower, and roll onto the gas faster. would probally help you alot.
if your just using the heavy RIGHT REAR spring to get intothe corner, then you have to deal with it getting you loose off the corner. so maybe you should raise the left front spring, that will tighten you up on the entry. then go with like a 200 rr and 225 lr.
as far as angle, i would start out with 15 deg left and 5-10 right to begin.
as far as left rear bite, you seem to want a tight car on entry, so dont put very much in it i mean like put 60 or so.
you seem to have the car kinda off on set up and just trying to make it work. i would recomend starting over with a neutral set up like 225 lr spring 200 rr, bar angles like above, and 60 pounds lr bite. and on slick dont get into the corner like a bandit. you want to get in smooth and get on the gas as early as possible.
good luck

Uhh , when I say gettin in like a bandit ....I guess that's just too extreme , it just gets in real nice and lil tight like ....feels good . I don't slam er in there ...I like to drive real straight all the time if possible . THIS sounds a lil nasty .... aaaaaaayy ! He he Back to racin ....I generally always ran the stiffer lt. rear spring as you advised ZERO ....just thinkin bout stuff . I don't know if it's the wrong direction or not but ....you see what i'm aimin for ? Gettin in killer and gettin off killer . Thanks

Ohhh , almost forgot ....do you think the car will never get off as good as long as it has the stiffer rt. rr. spring in even with the big lt. rr. bar angle ? Thanks

We race on a semi banked 3/8 mile track that starts out fairly tacky, then turns dry. Lately, I've talked to several guys that have gone to running stiffer on the RR spring than the LR. They said that their cars are good on the tacky, then when it dries out, they throw some lead on the RR. The explanation they gave, was that the extra lead on the RR helped the car rollover entering, & the heavier RR spring helped bring it back to the left exiting. The guys doing this are always running up front. Might be something to it.

if you put the left rear spring in front and right rear behind then it will tighten the car up over all and alot of people like that on dryslick. then if you run a heavy rt rear spring then it will not be as noticable when your on the gas because your unloading it then, so it will act softer on the gas and act stiffer off the gas.

Will a softer lt. rr. spring in frt. on my 3-link help it get on the bar faster like the late model guys say it does on a 4 bar behind ? They say it does because the softer spring will collapse faster thus allowing it to get on the bars quicker but I know that's 4 bar stuff .......just not sure if it's the same principle or needs that stiffer lt. spring on the throttle to get on the bar easier with 3-link also ? Thanks

155fan How much does the car weigh with driver in seat & what wheel weights? What are the front springs & where is the weight bolted on at? Does the wheels line up front to rear & if not tell how the rear sets from the front. cd2

Metric clip and lowers 1050 rt.frt. 900 lt. frt . and i'm not in the garage but I think the fronts are about 510lbs. each and lt. rr. is 860 rt. rr. 660 . These weights are real close and 50 lbs. of lead about mid way up on top of the rt. side lower frame rail . The left side wheels lineup about even but the rt. rr. is sucked in quite a bit from the rt. frt. and this is full of 32 gal and me in it . Thanks
