Cool project.

These should work well. I believe 949 was using these on one of their cars door bars to allow customers easier in and out for ride along. Pretty cool units.

<p>Collecting suspoension parts. Picked up a set of these yesterday. MSM Bilsteins in for the DIY coilover set up.</p><p><img src="http://cimg6.ibsrv.net/gimg/www.miataturbo.net-vbulletin/1480x2000/80-cdnn0xa_15b4fbafdb33e7e63e936748bb816d430322afca.j pg" title="" />And a tentative cart of things to go with it.</p><p><img src="https://cimg5.ibsrv.net/gimg/www.miataturbo.net-vbulletin/673x586/80-cart_9b3b13437007402fa3106f9dff40e224923ddc6e.png" title="" />&nbsp;</p><p>Any one have input on Summit Racing springs? They're inexpensive, and that's part of the the purpose of this build. Look like a worthwhile option.</p>

<p>ive never bought srpings from them, but i found thier house brand stuiff is always pretty high quality for the price. of course they are just rebrading, but ive noticed they are usually name brands. example: i bough an FPR from them for half the price of the holley. i recieved a holley in a summt box. i wouldnt doubt the springs are made by moog, or afco. if you call and ask, they usually divulge the details.&nbsp;</p><p>&nbsp;</p><p>car looks great so far! but&nbsp;i hope you dont include that raised bar that went in the middle in the roll structure in V3 rendering. it looks goofy and doesnt look strong.</p>

Hi Sean, lol. <br /><br />That's good to hear, and inline with everything else I've heard about Summits branded products. <br /><br />That third bar was never my plan, lol. its been replaced by a corner to corner diagonal. <br /><br />Thanks for the input!

<p></p><p>&nbsp;</p><p>hi mike, that should be much better, both in form and function. maybe even an X with slightly smaller tubing?</p>

<p></p><p>&nbsp;</p><p>I think one diagonal should be plenty. Try to keep weight away from up top.</p>

This project is still alive! ..though slowed some. That happens when a hobbyist chassis builder gets busy with work.. But there's an update on some progress. <br /><br />Rear suspension is coming, upper arm has been relocated to a rearward mount with a modified (butchered) stock upper arm. What would have been the rear arm mount is now the front, with the front section cut off and moved the rear. A plate boxing will connect the two. <br /><br />http://imgur.com/a/wCRcf

Hello, back again. <br /><br />Major update. The chassis for the most part is done. It sits on its own wheels. And it sits with TONS of ground clearance. <br /><br />The shock tower location were matched to OEM location, and the car currently sits on OEM spring and shock. The front shocks are at full extension, and the rears are only compressed ~3/4" or so. I haven't scaled the car yet, but its very light. <br /><br />Attachment 234292<br /><br />Attachment 234293<br /><br />Attachment 234294<br /><br />Attachment 234295<br /><br />Attachment 234296<br /><br />Attachment 234297<br /><br />It will be home soon, where the real car work begins.. Hopefully more frequent updates moving forward!

Scaled the frame and engine this morning. It weighs in at 1200# as you see it in the previous posts. Heavier than I had hoped for, but we'll make it work. <br /><br />Started doing some planning. Still need to pull the pedal asset and steering column from the 2001. Test fitted the stock rad from the 626 (large, heavy) and stock rad from a 1999 Miata. I think I'll be using the smaller light Miata rad. <br /><br />Attachment 234291<br /><br />Over the next week or so I plan to gather the pedal and column, mount the seat in an approximate location to begin pedal and steering wheel mounts.

Meh, I would put radiator further back and set up so the rad is mostly even with or behind you and the hot air goes away from you. But that's just my idea.

I hear you. That was my original plan as well. But moving it up will help in offsetting the weight of the motor over the rear axle, in an effort to balance the car more. <br /><br />I'll do some ducting to dump the hot air towards the rear control arm and axle area.

Subbed!

Any updates? I know this thread is OLD - but any progress?
