Hey guys,

I've had a chance to prototype a few new 1G products lately, and I wanted to chime in to share and also to gather some opinions. I still need to test this stuff on a few cars before it's available. But once available, I will have ads in the Freelancer section.

I'm working on a 1G rear upper control arm. These will offer a greater adjustment range and also save around 1.5 lbs weight on the car. These are similar to the Afco DIY kits that some people have been using. The differences are that my arms will have a stronger tube, a much better heim joint, and properly fitting standoffs that won't require modification. The inboard end will feature a chromoly, teflon-lined heim. The outboard end will be a very nice Moog tie rod end (booted and zirked). The tube itself is a large OD extruded aluminum tube. Very strong due to it's hex shape, and reasonably lightweight as well. Pricing will probably be around $200 shipped for the set.

I'll also be offering a 1G active toe eliminator kit. These will feature a chromoly, teflon-lined heim. I'll also be including 4 small round caps to use to weld over the factory bolt holes. I'm hoping to be around $150 shipped for the kit, so reasonably competitive.

And last but not least, I'll be jigging up a 1G rear subframe in the coming weeks. I'll be designing and building a prototype tubular rear subframe very soon. And there will be options for a 1G rearend or 3000GT rearend. I'm very much looking forward to this project. I hope some of you guys still want something like this.

Anyway, that's all I have for now. Feel free to post any suggestions or opinions you may have. I welcome any constructive criticism. And if there's another 1G rearend product you want, let me know.

Thanks!
 
Retaining the rear sway bar will definitely be an option.
I'd be curious to see how you do it. I've been kicking the idea around for a bit but I always gave up at the lower control arm swaybar mounting situation. Thanks for even putting any effort into the 1g stuff. Even though many moved on to Evo's and GTR's and such, there's still a few bitter 1g graybushes like me that refuse to conform. "Get off my lawn you kids!"
 
Ill deff take a tubular subframe. By any chance will you ever consider building a front subframe also? Also rear lower control arms with sway bar attachment would be nice :sneaky:
 
Any chance for a bent upper control arm option like the Ingalls arms? Cioc has experienced problems with the straight tube arms before. His experience can be seen in post #104 here: http://www.dsmtuners.com/threads/rear-lower-control-arms-how-to.365660/page-5
Thanks for the link. Is everyone else having the same problem with a straight upper arm?

I could definitely offer a bent version. I'd use 4130 tubing, bend it in my bender, and weld in threaded ends. It would have to have a double adjuster for adjustment, and I'd also have it powdercoated. Definitely doable, but it would add around $70 to the final cost.

As far as options and quality goes, I can offer just about anything - I'm just afraid of going overboard and putting out an overpriced or overly expensive product. I try hard to run that fine line between quality and affordability, but I err on the side of quality in most cases.
 
I need everything, can you do the Toe in pieces for me? I can weld but you certainly do the work I am willing to pay for. Would you be interested in doing this for me?

Thanks

I am not 100 percent sure but I think some problems stem from a crappy heim in combination with a full suspension cycle? I have the straight ones currently with no problem, however I haven't gone to Watkins Glen yet so I don't know how they will like track-use. I don't really understand why heim joints are used in the first place other than you can buy them off the shelf with the correct threads for the swag tube used. I rather have an oem style bushing end.
I'd also have it powdercoated. Definitely doable, but it would add around $70 to the final cost.
What if you nix any finishes/powdercoating? Negligible cost difference?

I don't mind offering a welding service for them. But I don't think most people would be interested due to the hassle and costs of shipping the knuckles back and forth.

I assume it has a lot to do with his specific ride height and available suspension travel.

Heims are great for suspension components. 3-axis movement without bushing deflection. And the threaded connections allow for quick, easy, and infinite incremental arm length adjustment. But you definitely want to avoid the carbon steel, economy heims.

Nixing powdercoat won't make much difference. It's all in the materials. I spend more money on two tubing ends than I do a threaded suspension tube. Plus the price of 4130 tubing and a 4130 double adjuster. And then a labor cost...

How about rear trailing arms like racefab does for the Evo 1-3 ?
 
I don't mind shipping back and forth, there is no substitute for competent welding, sent you a PM as well.

I haven't seen it. Got a link?


On a 1G, the "trailing arm" is built onto the knuckle. For my subframe kits, I planned to cut it off, plate it up, and go tube forward. The downside is that it would require everyone to send me their knuckles for modification.
 
How about the lower rear control arms but with sway bar attachment?
I working on that now. I'll definitely have something for that by the time I have a finished subframe kit. But I'd like to be able to offer those arms prior to getting the subframe done.

I have materials purchased and I have a 1G in my driveway now. Hopefully I have something to show you guys in the coming weeks.
 
Be careful of using adjustable lower control arms if you dyno your car. Most places will place the ratchet straps on the lower arms and I've heard of a few occasions where the the arms snapping in half.

Also having an option of a bushing would be nice. Heim joints are horrible for street driven/daily drivers. They wear out and get sloppy incredibility fast.
 
I have rear tubular control arms top and bottom. I also have the heim joint trailing arms. I did it myself years ago. I mounted the sway bar to the trailing arm with out any problems. If you check out my profile and photos you will see my modds.
