I can't emphasize this enough.

Ooops, well yours would probably be heavy right side, I forget about other countries and my background is circle track (cars are built to be left heavy).

Hypothetically every car would be different, where the gas tank is located, steering rack, ecu, battery, air conditioning, they're all placed in order to package everything well with enough space and to balance the car. Generally as it's a road going vehicle, designers assume 2x, 4x, 6x passengers, but when you're setting up for racecar, unless you've got a navigator in the passenger seat, you'll be designing for driver only (and designing around no driver is foolish unless you've got an autopilot), an extra 100-250 lbs on the left (or right) is inevitable in production cars.

Most world cars are built the same though, your car probably comes out pretty close to the Vorshlag corner balance on page 1, steering wheel, rack, pedal box, brake booster, (battery on this car), a few things flip over, but all the major stuff remains the same, it's rarely a perfect mirror image.

I put foot in mouth in this thread.

However, most high end dampers all behave similarly, and that is, they keep the car planted. Lets see if I can convince CSG to pony up for a set of MCA dampers...

Haha, I meant to see if you could come to some sort of trial business arrangement!

I'm going to guess it's just as important to have ongoing support; just getting product here to sell is a tiny part of the issue if it's not a "dispose when done" product.

The dampers I am thinking of are made to measure. I could, if I the experience, know how and money specify the damping curve I wanted.Their through shaft dampers start at $12k AUD a set. And no, through shaft dampers are not on the shopping list. As it is my proposed budget only allows for low speed compression damping adjustment which is why the more information I can supply the more accurately the dampers can be tailored for me/my car. I would be relying their expertise to fill in the blanks.

What dimensions/properties are customized?

You tell them as much (or as little) as you can. Each damper set is made to order. So spring rates and damper curves are customised to the customer's requirements. For a person such as myself I would be relying on their expertise to give me a damper. I will discuss regressive damper curves with them just for a better understanding of damper design. I am in no position to request a particular curve.

What I thought was a little controversial was being told they do not offer 4-way dampers. Even their dampers for the V8 Supercar series are only 2-way adjustable. (There are only 3 sanctioned damper manufactures for the series: Sachs, Ohlins And Supashock.) They also don't use remote canisters.

If you aren't sure what to ask for, how is this crazy custom setup going to help vs one of the proven OTS options?

I guess I'm still unclear as to exactly how they would use your corner weights.

I think the value here is in learning what to consider given the options.

I'm curious.

When I ordered the AST 5200 all I specified was spring rates and double digressive valving. The rest was left up to AST.

Just because I can't tune BRZEdit doesn't mean I don't appreciate the small increase in power.

I don't have to understand the workings to see a benefit. Having said that there is no guarantee at my level I would see a benefit. That remains to be seen.

My point was more, if you don't know how to communicate what you're looking for, or know what you're looking for, I don't see the benefit.

This isn't meant as an attack, but if you can't figure out to put on the stock suspension or access other data to find stock Weight Distribution, can you really talk about hysteresis, where the "knee" is in the valving, etc.

In reality, amateurs like us that may be quicker than most guys at a track day, typically still don't have the skills/feel, testing, etc, to spec dampers. It becomes kind of a "street cred" thing on what you spent.

They can make regressive dampers ala penskes?!???!???!?!?!?!?

This was only mentioned in passing but they said yes, they can do that. I intend to quiz them some more about that when I chat to them next.
