Ecotec 510
Re: Ecotec 510
Bad ass rear control arm!! Do you at all worry about the heim joints breaking? Since they are designed to be in tension or compression and you are side loading them when cornering force is applied? Also what does one of them weigh?

Just a simple clevis mount with room to offset the shock outboard of the oem hole. This gives me clearance on the inner wheelwell, and packages the shock high enough that I can use all the travel.Steinny wrote:Just read through this build. Amazing job man. One quick question, do you have any pictures of what you did to the rear upper shock mount? Looks like your coilover has a spherical bearing on the top hat as well and was curious. Keep up the great work!
The rear arm heims are monsters! Alloy 4340 3/4 shank/ 5/8 bore something like 25k lbs rating. Overkill so I don't have to worry about wearing them out or breaking one. They're not really being side loaded, it's more of a moment force. The outboard is mounted horizontally, it is adjustable up and down to tweak roll center height.icehouse wrote:Bad ass rear control arm!! Do you at all worry about the heim joints breaking?

Re: Ecotec 510
Redesigned my front uprights. Minor improvements from my previous version, mainly these are much lighter (4lbs/side) and cnc machined from one piece. Using the same 370Z hubs, howe racing ball joints and Bilstein universal motorsport 46mm struts. Managed to reduce the scrub radius even more, allowing clearance for wider wheels without rubbing. Working on extending the a-arms and steering links to make up for moving the ball joints outward.

Very nice!
Re: Ecotec 510
Fantastic ! Think every everyone would like to have the knowledge and skills to do something amazing !
Oh by the way the coilover doesn't have to be in a straight line to the lower knuckle at all ?

Re: Ecotec 510
I wonder how well your items would hold up to some off-road use? I am considering redesigning a front spindle setup for my 1200 Coupe and was considering aluminium for the job.
Have you done an FEA on your items?

Re: Ecotec 510
I did some crude FEA on them, didn't model the wheel bearings, which stiffen the knuckles up. I didn't go crazy on trying to make the lightest part possible, to do that I'd definitely need to use FEA. I think the best bet is to use 7075/7050 aluminum to engineer in some overkill. I'm not sure if off-road loads would be any worse than grippy tire lateral loads from autox/track.Mattndew76 wrote:I wonder how well your items would hold up to some off-road use?

Re: Ecotec 510
I think 7075 would be overkill with how much material mass is there. 6061 would hold up as long as the object wasn't thin wall.
