Quick question: Does the program use shortneck ball studs back and front by default on the outer links? Just trying to figure out to be accurate for shimming.

Thanks.

JoelV, just got back from holidays so sorry for the late reply.

Pretty sure it was a short neck ball stud. Just borrowed a car from one of the guys at our track and measured it quickly.

Just wanted to check in with the 240 or so who have downloaded the program. I haven't heard anything for quite a while so I assume the program is working OK.

I am curious though to see how useful the program is. Any feedback welcome.

I am still trying to figure out how to best use the program to my advantage.
i.e: What is the best procedure to follow to take full advantage of the program and how to really use it to it's full potential.

Bob,

The program for me has been very good and have used the settings in the program on the track. I was suprised with the results on carpet as the car finally performed the way I wanted it to, with the help/advice from a friend who studied vehicle dynamics. I now get even tire wear also.

One thing that I wouldn't mind is the option to calculate static roll centre with dive / anti dive settings. This may be asking too much, but I think it would be worth looking at.

Excellent work on this app. I am going to measure up my TC5 soon hopefully, if I do I shall post here.

A good question was posted above, what is the optimum roll centre and camber gain?

I would guess roll centre exactly on the track surface and camber gain such that you achieve 2 degrees (more?) at maximum camber gain.

Feel free to add your thoughts on optimum settings.

Regards

Neal

Thanks for the fedback guys. I was beginning to wonder if anyone was using the program.

Fatbear, I use the program as a setup sheet. Just add your spring rates, caster camber, shock oil and so on to the Setup Notes along with any handling comments and save the setup file with a unique name. I find it better than the paper sheets which I always seem to lose. Just change one thing at a time and note what it impact it has on the handling.

Redwood, Please do post your TC5 model. I have been hoping to see some sharing of models. I will update the Model data base to include any models posted so all can benefit. As far as an optimum roll centre and camber gain is concerned that is a function of each cars suspension geometry, track surface and tire package. The goal is to maximize tire contact patch (which maximizes grip) with the racing surface through as much of the track as possible. The best way to do that is to work on every aspect of you setup. This program provides help to illustrate what happens when you move the links around. Shocks, springs, caster, camber all have an equally important effect.

I would love to develop a virtual setup simulation that would look at all aspects but that is a huge task. Maybe someday.

Here is my attempt to get the program setup for the TC5.

I used a digital caliper but some measurements may still be off, hard to measure with the parts still attached.

Some notes:

The 2 outer front camber links represent using a small (black) or long (silver) ballstud.

The 6 outer rear camber links represent 0 shims, 1mm, and 2mm shims in the inner and outer position.

The 3 lower suspension 'shims' represent the 3 different hinge pin holders, the ones marked with 1,2 or 3 dots.

If you want to represent the effect of moving this hinge pin holder to the upper hole, copy the setup and add 2.1mm to the 'Y1' parameter.
This is due to an imposed 3 shim maximum.

I am running 3 degrees rear toe, this will influence the position of X1 greatly, so bear that in mind.

Finally, I am running the new aftermarket rear bulkheads, they should be identical to the stock ones as far as this program is concerned but I did not measure to check.

The file with the pictures on it seems rather small to me, so let me know if it doesnt work, I can type the values.

Thanks for the great program! Must have taken a while.

Regards

Neal

Bob,

I've definitely used the program to help make setup changes.

The version I'm using is 1.62, is this the latest?

Thanks Redwood. I'll add this model to the database. It is a hard to take some of the measurements without measuring the parts individually. Best to break everything down to get really accurate readings.

bkspeedo, You have the latest version.

Anyone else want to share a model?

Bob, would it be possible to make a web browser version of this program? That way I could run it on my mac or smartphone..

I've been using it to help visualized suspension changes, so thanks for making it! If you're bored this winter, connect the two halves of the car together for one big animation. That would be extra cool.

MaxRain, That would be sweet. I am actually working a website for my business right now. Once I get that up and running I might trying converting it to run online.

Greg, Connecting the two haves is the next logical step. To make it 100% true though need to connect both sides, and connect the front and rear, and add the springs. That was my original idea but became too complex for a first project. We'll see how deep the snow gets this winter.
