I don’t have any computer software as of yet iv always mapped roll centers out life size on paper. I have no way of knowing migration . Based on recommended starting points for roll centers is what I’ve done. I do not know if there is a function for that type of geometry u would know better as...

So there two types of roll center geometry that I know of. Most common is kinetic roll center does work. But over the last year I’ve been working with jacking force geometry on and off and found it works better than a kinetic based roll center geometry. Does anyone on here know of racers using...

Looking for decent base line set up for a straight rail asphalt late model racing on a 1/3 mile flat track 8/12 degrees of banking , 2800 lbs 57% left side 101.5 wheel base on 8 inch slicks with coilovers per rules . This car has jacking force front end geometry I would like try it this way ...

Hahaha you got it RM . We’re heading to the track early. I enjoy the education and have a never give up attitude. We will be successful …. I’ll report back with cardboard or without LOL. Have good day.

RM!! I gotta tell ya we went to practice this afternoon and made few small adjustments to the roll center moving it more to right and wow what a difference 5 to 6 degrees can make on handling. I have studied a lot and want to thank you for teaching me and others on this forum . Wish you could...

Morning RM yes I’ve read your literature on this and our track width is 64 inches and our left side weight is 57% so we do 64×.57 which equals 35.91. I had to do some specific modifications to the third link area on the CHASSIS which I’ve done and it’s exactly right where the third link needs to...

That helps RM . I’m taking a short course trig for dummies . Another question I have .,How much travel should we be getting? And if we travel the car to far how badly does interrup the roll center and its ability to plant the Right front tire.How far off the ground should the cross member be...

There some additional line here just figure out different a frame lengths and height I have lower frame set a correct heights . The thing I most curious about is how much migration I will get . I’m assuming I don’t want much .

I have to admit RM most of the calculations are you putting forward to me are beyond my pay grade let’s say I’m not too familiar with trigonometry, but I’ve watched a few videos on what sin is and the calculations of it but not 100% confident on understanding of it. i’ve mapped out the role...

Hahahaha Great point RM . I’m going go with your recommendation. Full fab perimeter chassis . Yes 8” tire durometer is around 70 . I’m going say we are bbss but not 100 %. And yes we can agree the tire needs more down force to stick . I’m going re map roll centers and get back to you . Also I...

Well RM I am conflicted right now because I’ve measured out my role centers and currently I’m sitting at 2 5/8 left of the centerline and 3 5/8 above ground and I know that you recommend 2 inches to the right of the centerline and 2 inches above ground, but I’ve heard some conflicting arguments...

With a traditional style roll center they are usually located to the right of the center line with jacking force they are located left of the center line. Maybe Ranger Mike could shed some light on this .

I’m looking at roll center geometry there two different styles. A traditional or conventional roll center and jacking force which one is more consistent or better on tires and why ?

I m looking to purchase performance trends geometry software what would be recommended as they make a few different versions?

What is the correct length a panhard should be . How far in front of the right rear axel tube center line should it be ? Asphalt late model on 8 inch tires perimeter chassis.
