CT9A Chassis Weakpoints
ah gotcha.. pretty much not worth doing if not at the price?
bump.. for SOME kind of easy remove harness bar -
i think dave's right about the fender bracing, in terms of what's already out there. would have been nice for one that doesnt require drilling but the market is just too small..
anyway just to reiterate, seems like the rest of the chassis is 100% fine, no need for rear subframe, blahblah, and definitely not all that cusco bracing crap. maybe some sort of triangulated trunk brace also

You really won't find another "easy remove" harness bar besides what Buschur offered for that short period of time. If you want one that bad, start a thread & get 5 people together to buy them at $475/ea.
In regards to the fender braces & drilling holes. Its 2 holes man, its really not that big of a deal. Not sure why you don't want to drill the holes, its not like it will weaken the chassis in that area. The 2 holes that need to be drilled are very simple & straight forward. It's part of how the brace stiffens up the front end. I've had the fender braces on my car for over 2 yrs & have no regrets about installing them or drilling the holes.

I completely understand the market volume just isn't there to compete with what ever is already on the market.
I also don't understand why ppl are so worried about drilling holes, I do agree the when installing parts which 'bolt' on less modification is better, but drilling really isn't going to do anything.... I'm also surprised no body suggested adding welds to the panels which are already there, its another way even OE's stiffen the body when they carry over certain crash structures....
you guys are right, as i said, i just thought it would be nice.
in regards to the harness bar, I'm starting to doubt whether we can get it going again but I'll try at least making a thread.

bump -
we now have a group buy going for the BR Quick Release Harness Bar -
For those of you interested, PLEASE post in this thread:

Not sure exactly how much it will be at this point, but as long as we get 10+, it will be less than 475.

...And reducing weight from the rear isnt as critical. On a stock to mild weight reduced setup evo I would rather keep the heavier oem subframe for better bias imo. Thats one reason I relocated my battery to the trunk--remove the weight from the front and transfer it to the rear.
When moving the battery back to the trunk, you're typically adding what, 5lbs of copper to bring the positive lead back to the engine compartment? I'm assuming it's getting grounded thru the chassis somewhere?
I was just reading in another popular thread about spot welding the chassis of the EVO. Personally I got a kick out of it.
Here is a quote from Mitsubishi concerning the EVO7-8 comparing it to the EVO6 which was already substantially stiffer than the standard Lancer:
"The Evolution strengthened it further by adding some 200 spot welds to suspension attachment, sills, pillars, floorpan etc. - the result is 50% higher torsional stiffness than the outgoing Evo VI !"
My suggestion if you are at the point that you want to substantially stiffen the chassis and the car is being pushed hard enough that it's going to actually help you....weld in a proper cage.*

And here they talk about the chassis of the X:

I wonder because I've seen the "extra spot weld" thing stated often but not documented. If we could know where Mitsu felt improvements were needed that would help us understand where we might want to carry things further.
There's lots of good information about the Integra Type-R published by Honda that's worth a look:

The Type-R is an incredible benchmark for factory performance, not unlike the Evo. What really stands out to the casual observer is how much energy (time*money) goes into developing these special editions, and how the OEM really works at the system level to reach their performance targets for the program. If it were as easy as "let's just throw on some Showa coil-overs and call it good", they (Honda) would have. But they didn't and there's a reason. Each and every new PN pulled costs an organization huge money, so they do it for a reason, and therefore the stupid looking bar in the back of the trunk in the Type-R as well as the Evo must have hundreds of engineering hours and a couple reports to back-up reasoning for it's existence.
I guess that's why I'm interested in this thread, 'cuz I "feel" that braces work, but like seeing some sort of testing to back up.
