4 bar toe

[circle dirt]

Anyone ever mess with toe in or toe out on a 4 bar setup?

111 views and no responce to the question. I was just wondering if you run the bars toe out at the front ,would the RR trail ahead when the rear end shifts to the left. I know it wouldn't be much ,but when looking at the model setup I have ,I noticed this

I have my bars set at 2-3 degrees toe'd in at the front but some run them straight.on my swingarm car they are straight zero toe.

1/2in. Toed in on rr and straight on lr. Or 1/2in. toed in on both sides. I run are's 1/2in. Toed in on both sides.

If you axle housing is straight, how do you get toed in on both sides?

U want the links to run at an inward angle from the birdcage to the chassis at ride height. To achieve this u need to slid your birdcages over towards the hub till u get the inward angle ( toed in ) that u want.

ok, sorry I thought you was talking about the axle. You was talking about the bars.

Can you tell us why?

I wouldn't get real crazy with moving the birdcages a bunch.. you can end up getting your spring angles way out of whack and can cause an ill handling car.. also toe in on the bars seems to make it more stable down the straights and not as darty

Thanks for all the input. Was just wondering. When I run the model through the motion it looks like ( when running the RR out ) it seems to let the RR move ahead a bit when the LR runs up on the bars so instantly the bulb came on.

Ok let's see if I can explain this in words rather then showing you. On corner entry sidebite is applied causing the rearend to slid to the left, if your links are straight the rr is moving forward just like the lr, if your rr links are toe'd in the rr will move back causing rear steer, if the lr links are straight the lr will get shorter, so if the lr links are toe'd in it will get even shorter causing more rear steer. So by doing this your car will turn sooner on corner entry allowing you to pick the throttle up sooner.

Moving the birdcages 1/2in ain't going to mess with angle that much. More angle in rr spring means more sidebite anyways. If your scared to move the cages over a 1/2in then move them a 1/4in and buy a bigger spacer for the heim on the cage. Its not as darty down the straights cause the rr links are driving striaght instead of outwards.

By this are you saying that all 4 links are pointed towards the driveshaft(center of car)?

Yes they are.

I have never heard of toe in or out on the R/R I would call it R/R trailing or R/R leading. We always run R/R back 1/4 inch on heavy and forward 1/4 inch when it dries out. That is with bird cage on 0 degree R/R 1 degree indexed on L/R
