Looks good Mark those new insert will do a lot better. It seems like your downgrading by going to smaller turbo.:spin:

Nice work.

Love it. You beat me in eliminations at map's event. You're on to something with a smiller turbo, I thought I would give a try....

Finished up the stronger rear 3rd member mount. Just need an alignment now.

My tube notching skills are improving. I started using a digital angle finder, the results are below:

I added a center support to the mounting locations, to make sure there were no issues with the design, in regard to the bolted joint preload. The rear end was used as the fabrication jig for these:

And finish cut:

Are your outer CVs 930s?

I remember Marco going with a tubular subframe after he bounced his pumpkin down the track ten years ago. Yours looks like it can handle the abuse.

Also, the carbon fiber must take up some of the shaft harmonics as I remember Brent was having issues with his one-piece aluminum driveshaft years ago and then he sold it to me.

Thanks for the kudos guys.

I'm not sure, they are dss pro axles made to work with the 3kgt rear. This is the dss description on their site:

"These axles feature much larger aerospace grade 36 spline bars (factory are 30 spline), billet ball & cage inner CV, and a Porsche-style 108mm outer CV"

Carbon fiber has about a 50% better critical speed than aluminim. An aluminum driveshaft that long will violate critical speed guidlines, significantly, causing severe vibration/harmonics. There are dsm'ers that have successfully used 1 piece cf driveshafts to over 180mph, it's proven to work. It's a good rotational weight savings too. I didn't weigh the exact difference, but it's noticeable.

The mostly likely are the Porsche 930 CVs then.

Some people on Hybridz seemed concerned about their strength in the setup that went in my car, despite the fact they get used in a lot of stuff.

Which I thought was kind of silly.
