Better description: "more body roll, less body pitch compared to other generally fast Longhorn cars."

This helps you look past the narrowly focused discussion about RR components and move on to...

I reject this. Change the stiffness matrix of the existing car (which is an assembly of many parts). There are many parts on a racecar that changed after they leave the factory; Tires, shocks,...

It is hard to "like" a comment here. The forum needs to adapt to 2022 and mimic some disruptive social media trends.

You guys are really getting into the weeds of component details. Tubing...

I am impressed that Billet cut that whole car up! Must have been one destine for the shelf.

We are setting up for some tests this season. We have measured on-track deflection and are quantifying...

6. This car did not have a sway bar.
7. This car had data? or just subjective driver feedback?

I will guess the car got looser overall, but possibly had better corner entry mid way through the...

Load cells are to include damper and part inertia loads in the data logging unless some of you have torsion bars. Just another way to gain insight into what is the most sensitive tuning knobs in...

Chassis flex: Does it matter?

I am poking the board. Motivated by some brand promotion for simulation software. (if your company is doing simulation of mechanical systems, consider Siemens...

- First you need to be able to measure what you are trying to optimize. So reflect on your measurement system or limitations before getting too creative.

- F1 was most concerned about aero ride...

Center-pull Sweet racks lower the rack pivot of the tie rod, requiring a lower steering arm location on the spindle. It is a screw-on part that MB sells. That will give you more tie rod to frame...

The further left the engine, the more angle introduced in the driveshaft alignment at full droop. Getting idealistic in here!

The CG moves about 0.500” left for each 1” of engine movement. You...

Take the leap and upgrade to the 2016 and newer. ....Or build your own. It was a steering arm height and small ball joint height change. Center pull rack on RF motivated the modification.

It can be argued that is the intent of cars with the oil cooler scoop facing the rear spoiler. I did not test to see if that works, or just creates low flow across the heat exchanger.

I put my...

<- there is a constant Keyser ad for wireless data acquisition using a string potentiometer for length measurement. These are great for slow speed test-rigs (like pulldown types). They are not as...

Remember the ground is "moving" at nearly the same speed under the car as the air moving above (hence rolling floor wind tunnels are much more accurate that static floor designs).

A cross section...

The driver mass is the largest mass variable in super latemodel racing from car to car. Most of our other components are similar in size/shape/weight. Your setup numbers will need to be different...

If you want insight into the pressures above or below the deck.... Nearly any hole in the deck causes air to go from outside to inside, reducing the downforce of the body. Oil coolers on the deck...

Billet - is this the '90s?

Figured it out. There is a size limit. Under 60kb seems to work. Above 100kb is out.

Assuming 5-7deg body roll.......wait.....Want to make this easier? Not Hoosier or anyone else is going to give you much data other than the starting number from the chassis builder (when the car is...

If your shock builder is your overall setup guru, then you should listen to them as their advice only works in a package. Just don’t use the rubber travel indicator on the shock as a guide for load...

Billet - it has been a long time since I have cruised the site!

@bcarrot28 - I would start by calling Audie Swartz. He as the most data on his cars across many customers.

If you want tune and...

bcarrot28 - you have a good question. No one is racing at 2" RR compression, maybe they hit a hole for second to get that travel.

Given many cars run similar motion ratios on 3 corners...if you...

Billet, that must be a crate car on a slow track. 0-20deg steering angle range? We should call that person something like Iceman.....

FYI - Ride Rate is the spring rate of the suspension measured from the tire contact patch. Basically the Wheel Rate plus geometrical effect of the wheel transformation from wheel center to contact...

Whoa. We also all start from the same place - zero knowledge. The state of the art is continuously growing and expanding. A growing knowledge gap every year that new racers will need to overcome. ...

Siemens PLM Software's Simcenter 3D Motion. It is based on an NX CAD platform. I drew out some cars to get practice after being based in Dassault Catia V5 for a long time. Lots of holiday time...
