Nothing is going to improve the chassis stiffness better than a properly built cage. Yes it will be 80+ pounds. I think my thought train though is looking at the fact 99% of the people out there are never going to tell that they put a fender brace on in the first place and if you are good enough to know you did then you are pushing the car hard enough a cage is a good idea anyway (say 140 mph speeds at Mid Ohio). A cage will save your noodle with that extra weight, make the car stiffer and yes, require you wear a helmet.

 

Here is what i was emailed about the UR fender bar fitment:

Hi,Sir.

Sorry for late reply.
We had consult to Ultra Racing Distributor,the fender bar can fit for EVO 7/8/9.Should be no problem to fit EVO 8/9.

The packages comes with both side,left hand and right hand.Please note that this only includes the Fender bar without the bracket.

 

I agree with David about cage safety. But I think that a cage represents a commitment. A cage on a 99% daily driven car is just to hard to work with. I attend 1-2 PDX's (135mph at mid-Ohio) and 4-5 Autox per year, but I do drive it year round. Finding a non-intrusive low cost way to improve chassis performance appeals to me. I would like to see David's team enter into this particular piece. It would bring a trusted name into what appears to be pretty simple to fab part.

 

Exactly, I don't think anyone's questioning that a cage will be the best option for absolute chassis stiffness, I think people are just looking for solutions that still allow them to take a Sunday afternoon drive without a helmet on.


Thanks, yeah I did hear back from them too and they said it comes with both. Didn't mention not having a bracket though - what bracket?

 

I'm with David as others have said, cage or stay home.

However - on the topic of stiffening the chassis, the single best improvement I felt when it was still a street car, was installing a harness bar. This bridged the biggest gap in the Evo which is the space between the B pillars. Made a very noticeable difference going around corners slightly faster then normal. I would not recomm anyone use a harness bar on a street or race car though for reasons you can find....everywhere. But that space, is by far the weakest point.

 

Cage is simply not a viable solution for everyone. We're talking about street cars here. Of course I'll say that with a race car a cage is a MUST, no one is questioning that. And if anyone is really seriously competing, they shouldn't be looking for ways to get around it.

Again we're not even necessarily looking for weak points - we're looking for RELATIVELY weak points - ie what's the weakest part of the chassis - I think everyone knows the chassis is already very good

While there is a point that if its just a street car and not a gutted race car, it doesnt need any chassis stiffening, we can still do what we want with our cars. If I'm not comfortable with a spot in the chassis, like fender or trunk, I'm going to get a brace for it.

 

So, does the autopower rollbar work as chassis stiffening? Its not a full fledged cage.

Balrok - Your comment about harness bar made me wonder:

Does the beatrush floor bar help at all? Its not at the b-pillars and much lower, but I wonder what the thought process behind the design of this bar is?

On a side note - I wish they made a harness bar with quick disconnects for the bar section, so passengers don't lose their teeth or have busted noses. I think it would work great if you could remove the section easily.

 

The search button must not like me. I don't seem to understand the contradiction. The single best improvement is not the one you would recommend ? can you give me another key word because harness bar brings up to many links.

Thanks

 

So, is the factory brace pictured above removed for the nagisa or UR piece? Thanks!

 

^
the factory brace stays in place and you add an additional brace

 

What about getting the harness bar, and not actually using it for anything other than just stiffening up the chassis...i.e. don't even strap a harness to it?!

 

I'm only using mine as a camera mount / chassis re-reinforcement

it still can get in the way of the stock seat collapsing in a roll over though

 

What's everyone's opinion on something like a 6 point with low door bars and no halo. granted the seat breaks or something and you could find yourself bouncing off the arch real quick. I'd imagine with a good seat and harness a roof collapse / entrapment would probably be the greatest danger in this set up though.

 

Haha, some of you don't know me very well! I will NEVER put a cage in the Bad Bish if I am going to EVER drive it on the street! The car has gone 9.04 at 159.64 with NO cage. Cages are not for street cars. I think my points have been missed.

I have some great ideas. I am going to look into a quick release harness bar and these fender braces. I love the idea of the harness bar being easily removable! We WILL build this! I will also build fender braces that do not require drilling.

Hope to start both projects next week!

Thanks for the ideas.

 

Please do it!!! Thank you!
