Thank you!

You can PM me here

Ha! I apparently can read minds. I edited my post refreshed the page and you posted this.

Will do.

Sorry I can’t seem to find a pic or link to this wall? Went on the Slon website, no dice. What does it look like, or did I miss out in a pic above?

Here is a question… does this panel stiffens the back mostly? If so would not it change under/oversteering characteristics of the car? Like a staffer rear sway bar? Should it be accounted by adjusting the front suspension? May be totally wrong just some partial knowledge from reading FCM thread on the old form.

Beautiful.

nope mate , so why we measure angles delta between both axles, one sensor on the front and second on the rear.
when we speak about chassis torsional rigidity, you need to know overall figure and improve it. so we've started from one of the most effective solution.

That is not stiffening suspension.

Advantages of Increased Torsional Rigidity

In the simplest terms, vehicles that have high torsional rigidity deliver a superior ride, superior handling and better response to driver input. Improving the torsional rigidity of a vehicle allows the suspension to work more efficiently and predictably. Vehicles with high torsional rigidity will see more travel in the suspension, as the chassis isn’t moving. Considering the suspension uses dampers and the chassis doesn’t, it makes sense why you want the suspension to move and not the chassis.

The chassis and suspension of a vehicle can be thought of as five independent sets of springs. There are the two front springs, the two rear springs and the chassis that acts as a fifth spring. If we cut a car down the middle and only look at what happens to a single spring in the front and rear along with the chassis, we are able to consider a three-spring model. When three springs are put in series, the force or load across the springs is equal. The weakest spring in the series will still deflect the most for a given load even if the other two springs are upgraded to a higher rate (stiffness). This is why some vehicles do not respond favorably to high-rate springs unless the chassis rigidity is improved first. Finally, increased torsional rigidity decreases rattles, squeaks and vibrations.

Wow that is a massive improvement in torsional rigidity. I guess I'm ordering a panel!

Soooo, nobody that has received one has actually installed it yet to comment on real world feel/improvement?

This isn't stiffening the suspension. It's stiffening the body that the suspension is attached to.

Suspension stiffness has upsides and downsides. Body stiffness is all upside.

Need to install the driver mod before the torsional rigidity mod lol

Don't think it makes sense to install this until I have more track experience, so that I can actually tell if there's any difference.

With almost any other go-fast part, I'd commend you for this line of thinking. That and putting any safety gear/equipment ahead of those same go-fast parts. But in the case of chassis stiffness, you're helping the car out too. You already have the part, I see no downsides to installing it.

Besides, we all really just want to see the pics

You are not cool enough for our carbon wall?

need to save this

[Obioban]

The wagon vs coupe difference is detectable just pulling out of the driveway, and this is a bigger difference than that. Should be readily apparent.

[IamFODI]

Yeah, should be beneficial everywhere, on or off the track.

Ha!!!

[Sharocks]

Even though I can't get into my backseats, I like having them. Keeps the Diffsonline diff whine away from me.

The CF on the panel is super legit though, I have to say.
