No DMacks are not more durable compare to by Michelins.
With the S52 240 dynoed rwd were going to any tires pretty quick.

You also need to consider with the reigers serious beefing up the chassis, especially at the rear. I'm using more FB than the forum, if u have questions

Yeah, no doubt. I expect the tread to take quite a beating. I'll have to find some lighter tires after I wear through the DMacks.

That's the plan. The cage builder will reinforce the top mounts and tie them into the cage. I'm running E36 Reigers, so need to adapt the body to fit the suspension any way.

Okay, sorry for the long delay in getting updates out, but the project was put on the back-burner for a bit and we were still working on the chassis repair. I just dropped the car off at TC Design Motorsports in Campbell, CA for the next phase of work, so it's a good time to catch up on the chassis and suspension work.


After the last photos were published, we decided that the floor was too badly compromised. So, we took the extreme measure of cutting the floor out of a donor car and grafting it into the E30 M3. It ain't pretty, as we went with a part that wasn't blasted like the rest of the chassis was, but here's the final result:




The cowl on the car was also badly damaged, so we grafted in the donor chassis cowl and a-pillars:






Here's the roller right before it was dropped off for the cage (with mis-matched doors back on the car). :-)






Next post will show the suspension reinforcement work we did.

While the chassis was being prepared, Nate Walton @ Bay Street European in San Rafael went to town reinforcing the suspension and subframes. We used the usual reinforcement parts and suspension adjusters from AKG Motorsports.

Here's all of the work:

I love seeing these cars completely stripped down and welded up. Thanks for documenting!

Wow, great build! I couldn't imagine rallying an e30 M3. Definitely would be a blast.

Beautiful to see this car being brought back from the dead.

Anything new?
