trying to keep my short bar! i run a double sided mount and have gotten the bar to 19 inches but i have alot of angle in it. it is 9 inches higher on the frame then on the pinion plate. checking with an angle finder it has 28 degrees of rake. what can i expect if i try to run it like this? will it work or cause other problems? thanks for any help or thoughts on this

When you stomp the gas you better have it pointed in the right direction!! Because it'll leave!

You might want to try extending your chassis mounting point or better yet moving it. Thats alot of rake and it will definatley affect the overall handling and might cause other problems. In my opinion, take the time to relocate the mount or run a J-bar to get more length.

Hope that helps.

Id agree. Try to move one end or the other or go to a j bar. I prob wouldnt run more than 5-6" at the most in that bar. If you cant get it to fit just go to a jbar. Might be easier than trying to stuff that 19" straight bar on the left side.

Yeah, I think anything over 20 deg is too much. Are you trying to keep it on the left of the pinion just for left bite?

well let explain this a little, change the car over last year from long bar on the back of the rear end housing to short bar on front.started out with 3 diiferant bars to chose from. had a 14,16, and 18 inch bar.tried the all during last season trying to find the one that suit the way i wanted the car to feel. started getting close at the end of the season with the 18 inch bar and about 7 or 8 inches of angle. so i am only running 1 inch longer and about 1 more inch of rake.will it be that much differant?

yes it will be different. How much??? I don't know and I doubt anyone could give you a truthful answer to that. If YOU think it will work, try it! Who knows you might find a combo that works great. Its all in the driving style! If it doesn't work, then you know what you've got to do.

Be CAREFUL!! I saw two cars thi year run the short bar at so much angle when the got on the gas the car overcentered the bar and locked up in the air. With it that high make sure it will not overcenter, If it will run a limiter chain to keep it from doing it.

be careful with short bars and lots of angle. i have sat a car on its right side before. stomp the gas and next thing you know you see nothing but dirt out the pass side.

if you think it will work then by all means try it. Everybody is different and tracks are different. I know guys that were runing 9"+ with a jbar so it wouldnt be that much different. From my experience though the shorter the bar the less angle you need and the more driveable it becomes. IF you are on a rough track short bars with a lot of angle are a handful to say the least. Remember that angle and split are different. 3" split between ends on a 10" bar will be more like 6" on a 19 and still have the same angle.

Also while putting angle in the bar may help with forward bite to a point, it may hurt you other places in the corner and actually slow down overall corner speed. By adjusting to make the car smoother and easier to drive through the corner then adjusting not only panhard anlge but trailing arm angle, LR bite etc for traction off the corner you might just be faster all around the track. More angle is not always the answer.

i am just trying to keep my left side mounted bar because i like the way the car get in the corner with it. i have never ran a j bar so i dont know what it will do. like i said i changed from a long rear mounted bar last year. the car was much better going in then with the rear mounted bar, not as loose getting in. my thinking was that even thou it satrts with alot of angle it won,t gain much during body roll because it is 19 inches long. or am i completely wrong with this theory.

thanks for the input

well as far as the gaining of angle goes..... the longer the bar the less it will gain at a certain amount of roll as compared to a shorter bar. The difference you will most likely see with changing to a J-bar is that the car will react a little smoother and most likely not roll over as much. I run a short straight bar but I have ran a J-bar. I like the straight bar because it fits my driving style better. So just try it and see how you like it.

i agree with flyNLoIMCA17. the panhard bar comes down to driver preference. I personally also feel lr bite, and rearend square or canted in the car is driver preference.
