    Hi everyone and welcome to this post about my tubular front subframe for the 2G chassis.

    EDIT*** if you can please help here https://www.dsmtuners.com/threads/f...ta-enquirey-i-need-you.531103/#post-153779373

    This thread is now going to be its own specific thread relating to this frame i have designed (many times i might add) and its where i can more openly talk about it and although i dont have any costs as of yet its where i will be able to discuss this.


    So a small back story of this and why its taken me soooo long to get this far.

    back in 2018 i got done making my rear frame and bought an oem front frame which then sat for a while being looked at as i walked by it then come mid 2019 i decided to figure out the jig as this was going to be tricky with the way i wanted to make the frame front the start which was modular* (will touch on this later on below)

    i ended up deciding on a full cage jig for strength and to retain structure its a bit OTT but thats ok, just more weight for me to move about.

    with the jig in its early stage i got to designing my first frame which i really liked but before long i discovered an issue once i made it after looking at the design for some time and that was diff case clearance. so i went and had to redesign but this meant from scratch again which was tricky at first but i got there in the end and a trial fit was needed, found some clearance issues and tried to work around them a few times etc etc and after a few revisions i had to redesign yet again!

    after all this i believe i am on design 4 and something like revision 9 and now the stage is complete and fine tuning was required and thats where i cam currently at right now!

    I am due to finish taking my data points from the frame and making jigs to mount to the jig to make sure i clearance everything the same each and every time! this is critical to be as near as equal for each one produced.

    -------------------------------------------------------------------------------------------------------------------------------------
    I have started off with the turbo subframe and later on i will be looking into the 420a frames if people from that engine platform are interested!

    I will be making 2 of these and im going to be working with someone so we can both get testing done but this wont be till i have done the initial testing to make sure im happy! only then will I make the second frame and have it tested by another.



    SO.... modular you say huh! whats that about?

    Well when i first started this project i wanted it to be unique and an advanced frame like no other for any car really and thats where alot of time was spent of thinking how to but not doing etc. was a tricky puzzle to solve

    * my original plan was to have 2 steering rack options but it turned out i was not able to make the other rack work due to the length and design of it which really sucked. it would of thrown off the steering and caused some errors i could not even for see no doubt.

    * The other part i have still kept and thats replaceable outer mountings for the compression arm. this means you can use the oem compression arm with no adjustment heights. then the replacement outer part will have a similer design to the lower arm bracket meaning you can adjust your whole front end to match the lower arm and thus minimizing any effects from lowering or caster loss just to name a few effects you can do with this! along with this mount will also come a compression arm which is also modular meaning 1 arm will work with both the oem frame and my frames and also adaptable from oem mounting to my mounting so no major cost loss to the end user which is a small upgrade piece. after all I am here to help save you all money!!!

    I will have a few options on these and i will confirm all this later on.

    those options are as follows...

    normal subframe. (included modular outer, and 2 point under brace to use with oem or aftermarket crossmember) mounts on the back location hole only! so aftermarkets will need to be reinforced on the 3mm plate.

    full race Subframe which will include a custom 4 point brace for added strength and support for below the frame for those corners, this will also come with a custom cross member designed for the 4 point brace only!

    The 4 point brace can be added at a later date with the cross member if desired as an upgrade, same with the outer mountings for the custom arms.

    the frames will come with either one of 3 options for frame mounting pads and these are.
    NOTE (outer mount will be direct mount to frame still.

    * Rubber for better NVH (better for street and more daily use)
    * Nylon for improved stiffness and some noise reduction (for those looking for added stiffness and those who do not mind a bit more noise/vibrations)
    * Alloy for full stiffness and no flex/movement on the chassis (full on race spec zero damping of noise)

    steering rack is now fully hard mounted so no rubbers required for this from your old rack! this means no slipping, no wearing of rubber.



    I think I have covered the most of it in bulk! sorry for the long read but I feel its a must for you all to know the process and all about the frame etc

    please feel free to ask any questions or just to show your interest.

    Thanks all

    pictures show from design 1 to what I have to date and what is finally ready to weld up once i got my data points

    I never mentioned one as im currently not sure myself but if plans go well and testing also then im looking at Q2/Q3 would be the area but i need to have all the braces and swapable parts made to test also as well as the arms so its a bit task but its all in progress

    Its going to accept all oem arms but the anti roll brackets will be custom but included with the frame. As always i will make sure its a complete kit and it will even include all new hardware through out the frame!

    These will fit both FWD and AWD 2G DSM's Correct? It's not explicitly stated if the Transfer case will fit or not.

    Its being made for the turbo subframe which is both fwd and awd, so what clears the factory subframe will clear with mine also since i have jigged up from that subframe. This is far more open and spacious then the oem frame is so nothing will foul from my view under the car even if i had a transfer case. The steering rack was the lowest part on the oem frame and it still is on mine.

    Im working with an AWD chassis also so it will be 100% confirmed for peace of mind later on anyway.

    Even knowing it still a bit of time for you to send it to production, we would still pay up front to ensure we get the part and not miss it when it comes the time and miss it by not be able to come and check in to see how the build is doing.

    So I’m with MOUNTAIN MAN, any time I’m ready for the deposit or full payment.:hellyeah:

    Already got a locstion for a rod or shaft/strip of metal for supports etc. It is tight on the passenger side for the trans and this but its possible to get it in. Worst case is mount the clevis or what ever first then add the bottom later once the frame is bolted down

    I dont know prices or anything to do this so i think its best to wait till im 100% ready on both ends. I also need to confirm they work as designed as thats a big thing and dont want to have to hold onto peoples money as if i forget exactly or the exhange changes it can cause all kind of issues.

    You mentioned in your other thread about having two pricing options. One for tig welding and one for mig? With everything going on in the world money is fairly tight. I know you wont know a price yet. But would be nice to know a eta on when a for sale ad can be posted. Like a few months or a year. And for pricing are we talking like 500 or 3k. Just would like to know some ballpark even if its just a estimate. I know there is a lot of time, effort, and support from everyone here. I been following this for a while now and look forward to picking one up if I can afford at the time.

    I might have missed in the previous posts but would this allow the use of my current rear motor mount and my current subframe has volk solid bushings and the control arms. Would this work with all that?

    Off subject but have you thought into making a 2g radiator support bracket like from bullfab? Also would be interested in a 2g solid front bumper support rather than that fiberglass junk.

    Right i shall list each one of these replys out seperate so its easier to relate to.

    You mentioned in your other thread about having two pricing options. One for tig welding and one for mig? With everything going on in the world money is fairly tight. I know you wont know a price yet. But would be nice to know a eta on when a for sale ad can be posted. Like a few months or a year. And for pricing are we talking like 500 or 3k. Just would like to know some ballpark even if its just a estimate. I know there is a lot of time, effort, and support from everyone here. I been following this for a while now and look forward to picking one up if I can afford at the time. I think the mig option is wise to keep costs down for all so it may just be 1 option. Tig is nice but its most costly from time point of view and mig is just as strong and is a least time consuming process so this will help lower costs some.

    Time frame i would like to ideally have testing done by summer on both cars (mine is still being built but i think after christmas it should be done) so if i have to put a date on it i would say around summer would be a time i would look into listing unless their is issues st which i would look into it and then delay it all until im satisfied.

    Price is really hard to say. Of course im trying to make a great item thats widely adjustable and upgradeable and shipping alone is going to be tricky as a quick quote recently said about 350 pounds shipping for it and thats for its box size not weight! Then there is what box! How to ship i have not looked into yet. I dont have any costs myself either LOL, CNC parts and laser cut parts will be done once i have finally completed mine and no more modifications are needed right now.


    I might have missed in the previous posts but would this allow the use of my current rear motor mount and my current subframe has volk solid bushings and the control arms. Would this work with all that? This will not work with any motor mount or subframe bushes as this is a completely new design to my frame. I will offer different pads for comfort to bolt to the chassis. The only thing that will work from oem is the arms as im not going to make people buy my arms just because! So those can stay oem if they want to and can upgrade later on to mine once released.

    Off subject but have you thought into making a 2g radiator support bracket like from bullfab? Also would be interested in a 2g solid front bumper support rather than that fiberglass junk. You talking about the cross member?? I dont see now radiator support bracket on their site. If its the cross member then yes its listed above in race version. It has its own 4 point brace and comes with a custom crossmember for that brace only. The 2 point brace will not come with one and will use the oem frame of someone elses but the rear needs to be reinforced as they make it with a 3mm plate only and its not strong enough to support.

    Dont raven make the bumper support? Im currently working on my front end so im redoing my supoorts so if i decide to make it an item i will look into it but i never intended to produce this item as its just a 1 off for me and the new rad design im doing for racing

    I dont know raven. Is there a website? Do you have your own website? And yes crossmember/ rad support. The bar the goes from the front of the car to the subframe. But I want a metal front bumper support.

    Raven do and they are on FB also.

    I dont have a website i think i will need to look into one but im just not there quite yet.

    So as above the only cross member im doing is for the race brace.

    The reason i dont make a cross member now for factory is price! I cannot compete with any on offer as by the time i ship them they would be more costly then everyone elses so its not really a decent option ror an oem replacement from myself
