gauging interest: sway bar bracket blocks

Postby Twibs415 » Mon Sep 19, 2011 2:18 pm

iv been looking into making small runs of parts to sell and i think the first thing i want to make are sway bar bracket blocks similar to the ones racing beat makes. i can make them for power steering cars or cars without power steering.

As far as price im thinking $20 for non ps and $25 for ps + shipping which i would be $3.50 or free pickup.

if anyone's interested maybe we can get a list going.

I'm sorta interested, but you'd need to be clearer about what it is you're building to get me to bite.

Is this it?

it would be just like that but id charge less than RB for them. the blocks will be 6061 and depending on cost im thinking i want to use stainless nuts and bolts but if not zinc plated.


one thing i noticed about the racing beat design is that the bolts that you use to preload dig into the blocks and kind of wear them a bit. but they do this so the bolts don't back off. i think a washer with a split washer might be a better solution that way the blocks stay nice and the bolts don't back off.

a little side note i may make an extra coolant reroute or 2 depending on how well mine works first. ill report back with my conclusion.

its not a zinc coating. the bolts that RB gives you are grade 8 bolts, which i believe have more shear strength then standard SS. thats important in this type of application where there is an enormous amount of shear force being introduced into the bracket area. thats the reason why miatas often break the sway bar mount arms. if anything, offer a cheaper alternative to the boxed in arms and ill be in for a set. i know mine is just waiting to snap like it did in the NA.

ps: CNC + SS hardware = you will be hard press to beat their price of $28 and make a profit. you'll need to sell a lot to make up for the prototyping cost.

edit: Stainless Steel Bolts

Stainless steel is comprised of steel alloy with 17 to 19 percent chromium and 8 to 13 percent nickel. Stainless steel bolts have high non-corrosive properties. Stainless steel cannot be hardened due to low carbon content. Despite many misconceptions, stainless steel is not harder than regular steel.
Grade 8 Bolts

Grade 8 bolts are comprised of medium carbon alloy steel. Grade eight bolts have been hardened more than any other bolt grade. This bolt is used in high demand applications such as automotive suspensions. Grade 8 is the highest rating on the bolt-rating chart.
Strength

Stainless steel bolts do not have an indicated proof load. Grade 8 bolts have a proof load of 120,000 pounds per square inch. The minimum strength of stainless steel bolts is 40,000 to 90,000 psi. The minimum strength of grade 8 bolts is 130,000 psi. Grade 8 bolts are much stronger than stainless steel.

It's not worth it. I looked into it a while back.

i dont see the point to be honest. youre better off making a nicely machined coolant reroute kit for under $100. id be in for a set.
