Strenghen Originally Factory Suspension Arms Cheap

[Proximity Motorsport]

Hey,

If you have access to a welder then your in luck. Can be done with stick but mig is alot better for thin material. Well here i go to explain how to strenghen them

• First off... you will notice nissan arms are three sided. If you box them in, they will obviously be alot stronger.
  
• First you need to get cardboard (cereal box) and cut it up to the shape of the arm so that it fits.
  
• Then cut out 3mm thick mild steel plate to the shape. I used oxy and then a bench grinder to shape. But if you dont have access to a oxy then a jigsaw may cut it.. and then angle grinder while holding it in vice you should be able to shape it.
  
• setup welder and tack it all in place and make sure its sitting right. If not break the tack welds and re-try. Also reason to do a tack on each corner is so that the weld does not pull the metal out of place.
  
• Once welded it burnt through the bushes but that was ok as they were replaced with superpro bushes.
  

Its pretty simple really. Can be done to any type of arm just gotta remember with control arms you need to leave room of a socket to get in for castor rod bolts and sway bar links.

Awesome idea! Very simple to do too! Will definitely do this when i chuck some 33 lcas in my 32.

One thing that comes to mind though, is that the LCA is often bent when theres a collision with a gutter or the like, so wouldnt this mean that the next weakest component will give way instead?

whats the go with the welds? they look like TIG, did you just spot it with the mig for the entire run?

hmmm, $4,000 for new wheels to lighten load on suspension then add wieght back on with 50 cents of metal. You would need semi slicks and well sorted suspension to put enough load on the arms causing any sort of bending. Not a mod for street cars or weekend track cars. Actually, this would be ok for rally.

its a great idea yet ure proberly better off just drilling holes for the bolts u need to get to,

as doing it like u have would put alot more stress on the un reenforced part and might acuatly make the arm itself weaker under heavy loads as any flex or movment instead of being over the whole arm will be on the spot that isnt re inforced, also the spot that already has extra load as the castor arms bolt there
