Hi, Hope im asking this in the correct place. I have a 1973 Datsun 140J im restoring and bringing into the 21st century. With the car getting closer to going on the road im looking into some upgraded suspension options. Get it handling a little better. And get rid of some of the factory positive camber these cars and a lot of others of this age came with. What im wanting to know is are these arms i am looking at fitting going to pass certification and what information will i need to get this happening smoothly. They are widely known as some of if not the strongest and top quality aftermarket arms available for these cars, Its the rose jointed parts that im unsure of. This is what im looking at any advice most appreciated. technotoytuning.com/nissan/510/ ... datsun-510 technotoytuning.com/nissan/510/ ... datsun-510 Thanks Brett |

Hi Brett,
Get the tech specs of the rose joints, and provide them to your certifier.
I did click the links provided, but that was just shiny catalog photos rather than any technical information on them.
Cheers
Leon

Coll thanks for that,
I'll endeavor to gather up some information and see where it leads from there,
Just making sure there wasn't a blanket band on them or something like that.
Brett

Thank you very much,
Going by what i know of the company and there reputation for only doing the "overkill" and top of the line work i feel they will be fine, but as i have time on my side i have requested the technical information they have on these arms and testing results etc. I'll provide this when it comes to cert time as i feel this will make it easier on the cert guy and make it an over all smoother process.

Ensure you get the tech specs before you pay the money  |

This was there reply. Has also stated that they have sold many units to NZ before and have not heard of any issues with certification. The rod ends we use on our products are all FK Bearing RSM10T and RSML10T (right and left hand threaded). The static radial load is over 16,000lb's. Spec sheet available here: www.fkrodends.com/RSMRSMT17.htmlIn all the years we've been in business, we have never seen a failure on these rod ends in anything short of the vehicle directly hitting a concrete barrier. Even in those circumstances, the rod end is very rarely the part that will give out. We have been in business for 15 years now, and have manufactured coilover conversions, lower control arms and other suspension components from the very beginning. On average we sell about 500 coilover conversion per year and over 1000 sets of various lower control arms. In all the thousands upon thousands of coilovers we've made, we have never had a single failure of the strut casing to forged strut spindle. We exclusively use original OEM spindles and strut casings in our conversions. My business partner (Richard Forbyn) has been welding for over 45 years now, and apprenticed in machining and welding at Mare Island Naval Shipyard in California (back when they used to do apprenticeships). He was lucky enough to spend time welding on nuclear submarines as he is left handed and in some confined spaces on submarines, a left handed qualified welder is required to reach some difficult spots. He is trained in all advanced welding processes such as welding titanium in a purged environment. Throughout his career he has been certified in all forms of welding, as many of the US Government jobs required the highest of certifications. His last certified job was with Aerojet Gencorp (manufacturer of the Titan series of rockets) here in northern California. They adhere to the strictest of regulations. Our suspension systems have been extensively used in road racing and offroad rally in every part of the world, including the East African Rally and Targa Tasmania. Nearly every pre-1987 Toyota running road race and rally in Barbados runs our products exclusively. Our long standing relationship with these rally drivers has allowed us to constantly improve the durability of our product. I am confident that our products will not fail under any sort of normal street or racing use, short of a situation that could be defined as a vehicular crash or impact with a solid object. If you would like contact info for the rally teams we provide parts to, we would be happy to comply. If you have any questions or concerns, please feel free to contact me at ggtyler@yahoo.com Thank you for your time and consideration. -- Gia & Gabriel Tyler www.technotoytuning.com |

Hi Brett,
Are they welding to a forged or cast part, or are they cutting the mild shock housing tube and welding to that mild?

From what i understand they are completely fabricated from new no second hand or exchange items are used,
The parts i'm interested in have nothing to do with the shock as the shock bolts to the ball joint which is an OEM item which is bolted into the new lower arm they build from scratch from mild steel then powder coat,
Ive just realized where i have gone wrong. When i copied and pasted the links i actually opened the items i wanted to buy but for some reason it has reverted back to the main page when you click on the links, What a stuff up.
If yo re open that page the items im looking at are, (read as you would with a book etc)
Box 6 (Front Lower Control Arms for Datsun 510)
Box 7 (Tension Control Rods for Datsun 510)
I may look at these items at a later date but i can see no issue with these for certification process,
Box 9 (Camber Plates for the Datsun 510)
Box 10 (Steering Outer Tie Rods Datsun 510)
Hope that is a little clearer,
On the note of the shocks. I have used R31 Skyline strut with the spring seats removed (were held on with 3 spot welds from factory) and then fitted the Datsun spring seats to these (same diameter) at the desired ride height of a 40mm drop with and engineer welding the spring seat all the way round the strut tube which is of mild steel construction). (R31 skyline uses a shorter insert so everything works out well in that area) This way i get a 40mm drop with larger vented brakes while retaining my factory springs at there factory length and preload. If i choose to lower car further i can fit off the shelf lowing springs and remain captive etc.
All this is 100% bolt in except for changing the spring seat which allows for a smaller diameter (factory Datsun spring) which is required to fit the chassis.
Hope that wasn't to much info to try get your head round.
From what i can tell from his reply and talking to a couple of Datsun club members who have fitted the above items they have had no issue with certification so should be ok. But it always pays to check with and expert.

Hi Brett,
Looks fairly promising so far. I am assuming the front lower control arms are a load bearing arm, so you will need to be working with a 1D category certifier to get those covered.
That does limit you a bit, but just means that you are likely to have to make your booking with a certifier a bit further in advance, as on average they are more likely to be booked out in advance.

Yea that doesn't sound to bad, The cars a 4 year build no time frame no budget thing just do what i can when i can so im pretty sure i can handle a little longer wait time on a certifier.
Thanks Leon
You have been a lot of help.
