Made my own torsion beam brace to see what all the hubbub was about haha
I know it will work when it is first installed with everything new and tight.
My question is with only one mount point at the top, how after six months of use will it maintain it's rigidity?
With the twist beam twisting and the bar trying to counteract that, one would think that the single connection point would eventually fugue.

So far the rear feels a little stiffer, but I need more time for testing. I've had my wife in the car with me so I haven't been driving like my usual self (maniac) haha.

Cool DIY beam brace:)
Thank you sir. Whipped it up during my 10 minute break at work haha.

Not sure what you mean. The bar is mounted in 2 locations not one.

The way it is done will cause a lot of stress in one plane at at one location will can lead to premature failure but in the mean time it gives you the ability to see if you want to either buy a bar or build a different one.

By two points that would be 4 total if looking at both ends with a top and bottom location being several times more resistant to the load forces leading to failure.

Great idea for a test section but not likely a long term solution.

You could start with a new pipe and then cut two vertical sections to weld the the end and cap them to bolt through which would make a big difference. Of course it needs to be welded very well and depending on material heat treatment could be needed.

It is mounted in ONE location on each end
Absolutely only one location wouldn't work at all.

Oh ok, sorry for the misunderstanding Dave. Yes, you guys are correct, this is something I do not plan on using long term, just testing the concept. IMO, ultimately the best design for a rear brace is what Eibach has made. The shop I work for is a vendor, so I may also test theirs later down the road.

Not sure mentioned in this thread but I modified a 5-way BMW Ground Control rear bar and made mounts for it, a butt load of work, far more than I thought it would take, just for testing. I forgot to take it to the track last fall and have not been back due to the EFR build but honestly I do not think I will be running it.

My car is not the same as stock so handling is very different from other cars, -1.9 camber and 0.0 toe, which I like far better for a high speed cornering car.

I have stock front bar with stiffer bushings and Steeda adjustable links to take out any preload but I will be testing a bit more front bar soon.

Normally I have ran little or no front bar and a far stiffer rear based on championship winning race car builds I have studied or spoken with the builder about with great success but have read some very interesting ideas on FWD setup that is making me think outside of that box now.

I have driven the Octane cars at speed on track and my car, there is a significant difference in how they react, I like mine better, more stable on high speed turns and still very good on mid and slower speed ones.

High speed ones can hurt you more so I really work to have just a bit of understeer there, neutral on mid speed and if possible a bit of oversteer on slow speed ones but getting those all to work just right, not always possible but always the goal.

--------------

I cannot comment on the need of a stiffer rear "bar" on a stock setup as I had only driven my car about 5 miles before I tore it apart to make all these mods I have done.

I just went out this morning and this was on the car.



Now I have an excuse to go for a drive and test FM radio reception.
As if I really needed an excuse. LOL

Looking great:)

I might end up getting one but for me it would be more for style since I never use the radio so will spend the money on go fast first but just might have to get one eventually:)

One thing I never looked into, is the NAV antenna there as well?

It seems maybe that it why the cost is seemingly high in this part, if so then I can justify getting one so let me know please:)

------------

Wing turned out great looking, I would love to know how functional it is, considering doing a yarn test video on it?

That would not tell everything but it can help get a good idea of all around air flow, strings go up or down off the back side for one.

-----------

You are doing things a bit over the top compared to the way I mod my cars on the outside but always in good taste, I rather like it:):)

Thanks, have a great day!
Rick

The NAV antenna is mounted inside the car next to the rear view mirror.

The Shark Fin does have a better aerodynamic profile then the OE base so in fact it will make your car faster.

I know we all want more power but that always comes at a very high price.
I am at Stage three so it does very well for my needs.
Since this is my daily driver I do spend part of every day in it.
I have been going after the look I want, as well as creature comforts and handling characteristics.

You are correct about the aero effect, I have been considering just removing the antenna completely for that reason, drop a bit of weight off the top as well.

Now that I know it is only a radio antenna I will likely do so and fill it with some silicone then cover with some vinyl wrap.

I do not want to drop the headliner when I run a cable for a rear view camera, which I must have for safety reasons, I might be able to tie into the antenna cable, have to see what it is, then less work and weight instead of running a complete new cable.

I really do get where you are on the power mods, it was where I was going to stay when I bought the car but I am such a long term modaholic I did not stick to that very well but it would of been a smart move for sure.

Attention to detail, taking weight off, cleaning up the airflow, they do add up and often times do not cost much, something I have done for decades, even more when it was all I could afford to do.

Thanks, very much appreciated:)

Where did you get that spoiler? That really makes a big difference.
