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 from 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 4G63/4 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 when its on sale will also come a for sale 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. as pictured here https://www.dsmtuners.com/attachments/img_20201018_111413-jpg.613691/
https://www.dsmtuners.com/attachments/img_20201101_140942-jpg.614844/
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! as shown here https://www.dsmtuners.com/threads/f...r-front-subframe.531218/page-4#post-153788980
My subframe weight is 8.05kg / 17.75lbs
Oem subframe is around 20kg / 44lbs *****
Oem crossmember is 4kg / near 9lbs
True street crossmember 2.7kg / near 6lbs
My cross member is 1.9kg / 4.1lbs
My 4 point brace is 1.85kg / 4lbs
My 2 point brace is 0.81kg / 1.78lbs
My compression arm outers 0.8kg / 1.76lbs
***** does not include weight for the stock engine mounts F/R *****
So a normal subframe you can be saving around 10kg of weight / 22lbs!! Thats alot of weight loss! Considering how much stronger it is vs oem
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. (outer are yet to be finished as compression arms will be made at the same time)
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.
This frame also comes with the billet ARB brackets for this design and will work with normal bushings as before.
********************************************************************************************************************************************************************************************************************************
UPDATE The price of these i have worked out is pretty close to correct and i have checked this and will recheck again. as i hope i got my currency conversions correct .
note that this will be a long period item so i will be listing these in pounds and you can convert it to Dollars at the time, it makes it much easier my end as the exchange rate may alter, shipping will be priced per person as and when to get the correct price but for now i will give a current base idea on prices, by the time this gets released i will hopefully be able to make a drop down list order form and it will be a bit more refined setup.
price will always be UK Pounds so always base the cost in dollars around that price please
price for the normal subframe (2 point under brace - normal outers is
UK POUNDS
£1725 UK Pounds which includes shipping and insurance
US Dollars
$2465 included shipping
Based on current paypal exchange rates at the time
*** If you wish to add the 4 point brace at the time of subframe order then that will be £350 plus + £30 for extra shipping charges and insurance.
*** If you wish to add the 4 point system later it will be more because of powder coating and shipping costs (price to be confirmed on this later)
*** If you wish to have it NOT powder coated then deduct £80 from the costs
I will be able to offer a wide range of colors they have in stock at the given time and some metallic colors which would cost a fraction more due to the increase in cost of the powder. at the given time of ordering i can supply you with a color list they have in RAL chart or other they have and go from that list
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
