Traction Bars
So, looking forward to a built motor project, I see wheel hop as a major issue. It was an issue n/a, it was a big issue when I ran a 13.1@110 and it will most likely be a major issue once I am finding the limits of my disco potato. I saw a while back where TravisR was talking about fabrication traction bars but I couldnt find much else on the subject. I have never been able to break my 60ft times out of the 2 second range due to wheel hop and it is killing my ET's.
My question is, how hard are they (traction bars) to fabricate and can these really be universal?

seriously though, I think the traction/slapper bar is a solution for a problem a miata will never have. since the diff is rigidly attached to the PPF and tranny, the diff cant "wind up" like a muscle car.

Those in your link are for cars with leaf springs. Won't work on a wishbone setup.
FWIW, I had terrible wheel hop. Always have. When I pulled the engine to turbo, I found my drivers side motor mount was broken in half. Switched it to the passengers side as that one was only slightly torn. So now I have a torn drivers side and broken passengers side. Made a big difference in wheel hop. I will 100% be buying some stiff *** motor mounts soon, and diff mounts too.
As for traction bars, I think Travis is working on some. If you want to build your own, get on m.net and search through the V8 section. There's a few guys there that have built some and reported good results with V8 power.

I'm hoping to get my car out of storage and into the shop to build some traction bar jigs. It is one of the main business lines for ETD (Welcome to ETDRacing.com 2.0) and therefore we would love to make some for the Miata also.

Well, as I've found out more about this, I read a couple of SAE research articles on it, read a book about it (carols), and I really don't think traction bars are the answer for an IRS. What you have to do is put a comprehensive kit together that works on alot of little things in the rear to kill the big problem. Traction bars will always degrade turning performance on an IRS suspension, and they have to be very carefully placed if you do use them on any car or you'll completely bind your suspension. So while you can bolt up a set of universal bars, they really arn't what you need, and you have to crunch alot of numbers to get any positive effect at all.

we just need something to hold the diff in place, it is winding up because its not hard mounted to anything. When I went from rubber to poly diff mounts it REALLY helped, I get very little wheel hop now where as I used to get it ALL THE TIME.
that and making sure your shocks are not blown lol.

Havent I seen a bar out there that bolts to the lower 2 bolts on the housing, and run to the rear subframe or something? I cant recall exactly how it looked ,but do recall seeing it. Dont remember the maker either. I also have a good bit of hop, but havent really gotten to try it out since new engine mounts. My old ones were fully ripped in half, so Im guessing it should be MUCH better now. Plus all new suspension bushings, so maybe that contributes to less suspension flex in the rear. Diff mounts will come when I get the 3.6 gear set.
Also, anybody ever used those PPF braces Ive seen out there for sale? I cant see how this would improve things much, but Trackdog claims a decent improvement.
