coming from designing off road truck suspension, I never thought MiataTurbo would be talking about anit-squat.

Subframe is more or less done. I still need to make a bolt on crossmember in front of the front lower tabs. I'll make that when I start on the exhaust as it will probably interfear. I might also add a jacking point in the very back so I can lift the rear end cleanly in one shot.
The thing was a real pain in the ass to make. I was careful. I used a jig. I had almost no gaps and good fitup. It still walked after welding. Usually it wouldn't bother me but 0.1" is a big deal on suspension stuff. I had to spend an ungodly amount of time asjusting and rewelding. Big big pain in the ass but all the arm points are within .020" and it mounts to the the car square and level. It'll do. Overall I'm very happy with it. It's 43lb even compared to 42lb for the stock subframe. Considering that to run the getrag diff with the stock subframe you need to add the v8r kit (which has a listed shipping weight of 20lb) I finished well ahead in weight. https://cimg6.ibsrv.net/gimg/www.mia...3a77850810.jpg https://cimg3.ibsrv.net/gimg/www.mia...98772baf75.jpg https://cimg6.ibsrv.net/gimg/www.mia...a7f4731bad.jpg https://cimg2.ibsrv.net/gimg/www.mia...f2af1de3e9.jpg https://cimg4.ibsrv.net/gimg/www.mia...a1f02403b3.jpg https://cimg0.ibsrv.net/gimg/www.mia...416d0d43df.jpg |
That is incredible. What does it weigh (rear subframe)?

I gotta stop just looking at pretty pictures on the internet. Wait, that's all the internet is really for right?

Progress has been slow. Machining work, day job, and travels have been keeping me away from the miata. I have finally had time to get a move on the exhaust. The plan is pretty simple. The long tubes dump as dual 3". The idea is to join them into a single 4" which has a slightly smaller area but still plenty (600hp unrestricted flow) for my needs. This single 4 saves me a whole run of tube, a set of resonators and a muffler. Back of the napkin says ~20lb savings. Does 20lb matter on my build? No, but 4" exhaust makes me pretty happy. I started building it working from the hardest point (subframe) going out from there. I decided that to avoid things from clunking about, the exhaust would be attached via 4" grommets at the subframe. This should prevent it from wagging its tail but still be somewhat OK with NVH. Bellows flex couplings to be installed before and after that "hard" mount to provide some give. Bends needed to be fairly tight; ~3" clr; so pie cuts it was.

wow. That came out a lot nicer than mine. lol

Finished up the subframe back exhaust. Now that its donem I can add a jackpoint to the subframe and brake line mounts and the subframe is off to powdercoat. An aside, the last photo is why stainless on stainless hardware is a horrible idea. Minimal torque and the nut completely galled up.

My god, this is so tits!

Cats! SO many cats for you!

Wow. Absolutely beautiful. Please don't paint it. Clear coat the subframe and call it a day.

Killer job on the exhaust man. Keep up the great work.

The sex is too much. I give up.

Why no updates? I hope you were busy putting it together :D.
