+1 Id be making something that looks stock, just like my 03/04 billet subframe...With integrated solid Titanium round bar
Id need a trashed subframe to chizzle apart to scan the square tube sections, so that I can get the geometry to cut those out of solid on the water jet....

That stay gets more attention than the rest of the bike does. I'm progressing in leaps and bounds on that bike. I just wish I could get more seat time on it with moving into the new house and all. And it still looks as good as new. Thanks.

Now are you guys going to care if I make a rear section to replace the cast part, that would require you to cut the trunk box off at the back? There isnt much room as it is, and if Im going to make a new rear section Im going to make it thicker and therfore the box will need to be moddified for that to fit...
If this works out how I think it should, I can have the plates cut out on the water jet, and the rear sections ready made too..So you guys can send in your busted subframes and I can re-enforce the sides. And cut off the rear cast section and replace it with my new solid rear section....

Ok I just had a look at the broken one I have here, and to me it seems that while the square tube does flex a little most of the problem is in the rear cast section...So I think the easiest way to tackle this problem is by adding some plate to the sides to strenghen the tube section... And cut the whole cast section off the back and replace it with something solid...Im going to try and design a new rear section to replace the cast part, that I can weld onto your OEM sub...And have it tie into the side plates also, so its all one solid unit front to back...

Let me get a prototype made out of the one I have here, then well go from there...And I can try to figure out how much there parts will cost to make...I could even sell them as a do it yourself kit, that you guys can have welded onto your subframes locally...That way you dont have to ship your subs out here just to be modded...Even though my TIG welder is sic with TIGing **** like this...
The shitty thing is if SI just made their round bars mount to the tube section of the subs, closer to the front instead of just the cast part at the back...This problem would be %90 solved just adding one of thier bars....I was very dissapointed when I recieved their round bar for the 05/06 because it was instantly obvious that the cast section it bolts to was going to blow up eventually...

i run sick inovtions 12 bar. it mounts to stock subframe. 3 bolts on each side. 1 through exhaust and 2 into frame. most mine have been cracking up in the area where the exhaust servo is. just past were the frame is reinforced from the factory. i did have one that cracked back on the cast part as well.

Here is where my friends is cracking at the cast section, right where its welded to the tubes.
First it starts to bend right where it cracks...And you can tell because the bar starts to rip through his tail and point really high in the air...
Then it cracks...This sub is brand new and already fucked, when I went to take these pics the passenger seat wouldnt even come off its already bent up so badly.... And you can see the paint is peeling where its bending, so probably his next scrape its going to crack...
I still cant believe someone would make a bar that only bolts to that cast part Its so ******* weak how can you think thats going to hold....Man if this was my bike Id be going through 1 sub every session! My buddy takes it easy and still fucked 2 of these subs with the SI bar...

Well plating up the sides of the tube section should prevent it from flexing and cracking there...And replacing the rear cast section will prevent that from breaking...And tieing all of that toghther with the side plates should make it all one very solid unit front to back...Flex is what get these cracks to start forming....

thats not where the problem is. it bends and breaks where coming from the main frame its two pieces of square stock that goes to one as its heading towards the rear of the bike. that IS the weak spot! where you are looking is weak to but not as bad as where im talking about lol

I'd like to have a solid subframe like what's been talked about here, but nobody is making them yet, so i didn't want to keep buying subrframes. It might look retarded, but it works. I would love to buy a couple of Johhny's if he makes them or if someone else makes something

So its not a complete billet sub but its made of billet parts welded together...And BTW nothing is bent those rails were cut out of solid blocks...

i just use the stock exhuast as a scrape bar. holds up real well and doesnt break the subframe. unless u do foot in bar **** then theres really no point in having a 12 bar and no need to reinforce the sub. u can get stock exhaust for free all day long and one will usually last me 6 to 8 months.

Some people are going to want to run aftermarket pipes....
