Final update before our pre-sale!

Flex-Free Cornering. Fiesta ST Trunk Brace R&D, Part 4: Testing Data

The testing of our Fiesta ST rear strut brace involved three different driving conditions.

Cornering: 30–40 mph, slalom

Braking: 50–0 mph, stop with ABS engaged

Acceleration: 0–60 mph, full-throttle run

Each setup (with and without brace) was tested on the same day on an identical surface and with the same driver. The tests are repeatable and will provide an accurate comparison of rigidity in the rear body portion of our Fiesta.

Results

Check out the plot below to see our testing results.

Fiesta ST performance results

These data points confirm our theory that the addition of bracing in this area of the ST does indeed have an impact on flex. Although flex in these conditions was not excessive, we did see a bit of movement.

Once the trunk brace was bolted into place, the results were very impressive; the brace reduced overall movement substantially. The acceleration and braking test saw less overall movement compared to our handling test. Movement during the acceleration and braking conditions noted above was limited to just 0.01mm with our trunk brace in place. For cornering, the stock vehicle saw nearly 0.25 mm of movement when in the slalom. We reduced this to 0.05mm with our brace in place.

Great results from a great looking product!

Coming Up – Discounted Pre-Sale

Now that we have a finalized product and positive testing results, we are prepared to begin constructing our first batch. We will be launching a discounted pre-sale for folks interested in picking up one of our first units.

Feel free to follow up with any questions regarding our Fiesta ST rear strut brace or any of our other Fiesta ST performance parts.

Thanks for reading!

Looking good. Did the car you tested with have any other suspension mods, or are your results an indication of stock performance vs just adding your brace?

Thanks for taking a look! Yes, our Fiesta is bone-stock in the suspension department.

You sir, are an incredible tease.

<.010" of movement in the stock setup seems incredibly low to begin with.

Thanks for posting the data! But yeah, I don't think it's possible for anyone to actually feel .23mm of movement in the stock setup (I don't care how good you think you are. Haha). ...maybe it's more noticeable with a super stiff suspension setup.

But for those of us with stock suspension, or with basic suspension upgrades, can you tell us how the bar translates into real world handling improvement? Are there any tests you can do for that?

Thanks for the input guys. Very true, the amount of movement is not substantial in these particular situations. I would compare this type of driving to an autocross event. It is very possible actual track driving will produce greater flex numbers. Unfortunately we do not currently have access or resources to acquire this data, perhaps something for the future.

It's past the end of the week...

Sorry about that. Our discounted pre-sale rate will be $159.95.

1. At this time we will only be offering the brace in black, but we will keep color options in mind for the future.
2. These are two tabs that mount to the brace to support the false floor. Here are some photos from Part 2 of the development thread:

3. The pre-sale is estimated to end 5/20, but we will keep you posted if this date changes at all.
