Drift Prelude stickers conorsev.bigca... Quick video showing you how to extend your own lower control arms. Using some arms for a nissan silvia as an example
I would have drilled a hole in the jig and tacked a nut over the hole and then used a bolt through one of the radius rod holds to hold the LCA rather than tack and then grind. But really if your only doing one every now and then it's probably not worth the extra time to modify the jig. Oh, and i would have just bought some 3x30mm flat bar rather than cut it from sheet.
That's a good idea. Problem I could possibly see is the Nissan lcas come in afew different lengths depending on the car it came from. The welding also avoids any destorsion from squashing the lca because they are open on the bottom.
+Guillermo Gutierrez it's a cigweld 125. Not sure the amps as it has an arbitrary scale. It was setting 2 and was just penatrateing. Because you weld both sides it's not that important to penatrate all the way
Never had any warping issues. I'm sure there would be some weakening but I have had a car with my lcas crash before and the lcas folded up like stock ones do with no signs of the welds failing.
@@Conorsev ty for the reply! I do my own fab @a shop but is farm use. nice to c someone doin work wo all the glitz of a big business. any similar channel recommendations?
depends on the design of the supra LCA. im not sure how they are made. if its pressed sheet metal like this then you should be able to do something simmilar
Ya, the cut doesn't need to be in the exact same place. The LCA's just need to be strait and the same length. Well I guess if you cut one in the correct place and the other on the wrong side of the LCA that would not work. They look good though.
No offence mate, but you should have purchased another set of Lower control arms (lca's) and cut 1 set 30 to 40 mm longer. That way alot less fab and you are welding the same material. Also you should always gusset the join. No matter how good of a welder you are ie, join week point. I know you said don't gusset your Lower control arms in case you crash. Don't crash. I would rather bend the K frame then have a Lower control arm let go because of shit welds and the highest stressed part of the arm. You would be surprised that once the arm is in place and you wind the castor on the stress in that part of the arm.
a 2nd set of LCA's is not in the budged. no sense cuttin up an extra pair when you can just use 2 and make the middle part. As far as reinforcing them. We have run un reinforced ones for years in out cars here and in japan and so have thousands of other people. Meanwhile you can change your k frame and we will be out driving. Sometimes crashes are unavoidable.
Conorsev . Like I said no offence mate. You did do a great job with the modification. Do you have room in the K frame to redrll the inner bolt location. What gains in negative camber did the extra length give you?.
the problem with changeing the mount locatoin is it changes eveything attached to the lca. extending the lca where i do means you can still use stock castor rods, sway bars and the geometry will be pretty much the same. if you move the entire lca out then all the mounting points on it will be futher out as well so you will need to re do heaps of stuff. also i think this was a 25mm extension. to extend the hole out 25mm is going to take alot more work then just making the lca longer
Awesome video thank you! You got a sub
M&R Tuning cheers mate!
finally someone on youtube that’s knowledge and leaves guesswork our of their videos. awesome work and quality
Damn 10 min video with so much information 👍🏽 great video!
Great video. Tacking the existing arm to the steel was clever. Would never have thought of doing that.
best way to keep the cuts consistent and keep things accurate
This guy knows what he's doing ! Hell yeah
super informational - thank you!
no wories!
Super informal and great camera work, man!
This is awesome! I love your approach to fabrication.
Brilliant video, thank you for explaining the process! I learnt a lot from this video.
You made me laugh. You get a like.
Now I’ll go dig through your catalog.
Gotta say mate, theyre some very decent welds for a gasless mig!

wow, such a good video! you're really good at explaining!
Very good video!
thank you!
Great video. spot on!!!
Really good video man, subscribed :)
thanks!
Good onya mate
Great video dude well made. What does extended LCAs do for the car? Is that to run extra camber?
afew different reasons. more camber. wider front track. more inner clearance.
Awesome how to man. Question what kind of welder are you using or how many amps you think is best to get for this type of job
+Guillermo Gutierrez it's a cigweld 125. Not sure the amps as it has an arbitrary scale. It was setting 2 and was just penatrateing. Because you weld both sides it's not that important to penatrate all the way
did you have any prob with warping? figured full weld an slow cool 'while in jig". Did the heat weaken the OEM material on either side of welds?
Never had any warping issues. I'm sure there would be some weakening but I have had a car with my lcas crash before and the lcas folded up like stock ones do with no signs of the welds failing.

I really like grind hard plumbing co and this old tony.
this vid made me sub...
What does extending the LCA do to the cars stance or handling? Im noob
it pushes the bottom of the wheels out. this gives more camber. more inner clearance for more lock and makes the front track wider
Where did you get the fluorescent yellow spray paint?
just the local hardware store
Hey man, nice vid, just wanted to know whats your welding tool ?
It's a cigweld 125
What wielder did you use to wield these control arms? Thanks!
+cspeed868 it's a cigweld gasless 125.
Would the same method work on a mk3 supra?
depends on the design of the supra LCA. im not sure how they are made. if its pressed sheet metal like this then you should be able to do something simmilar
Are you using flux core for welding?
Yes
How strong is flux core welding?
@@red666A just as good as gass. flux core is more like a stick weld then a mig weld i guess
You welding with flux core wire ?
Yep
Holding?
Was this gasless mig?
Yep
@@Conorsev How did they hold up?
Car that had these particular ones has been crashed. Bent the arms. Welds held mint. Done heaps of sets since then and they old up mint
@@Conorsev Thank you for the replies man really appreciate it and your work is awesome
Any chance you can pm me I’ll pay you to do me some I need them ASAP!!!
Are you in Canberra?
Nah mate damn qld
Way over complicated cut placements... just measure and cut lmao
Ya, the cut doesn't need to be in the exact same place. The LCA's just need to be strait and the same length. Well I guess if you cut one in the correct place and the other on the wrong side of the LCA that would not work. They look good though.

Well that just seams like overkill. I have never had a modded LCA like this fail. This is just how pro built extended LCA are made.
