I think what maybe you're missing is that swapping parts doesn't always = a better chance. Differentials effect handling. A tight clutched diff will make the car tighter than with a Torsen style unit. A car with power that might not be a big deal as you can steer with throttle.. this car doesn't have much power, and already have a big bias ratio Torsen to apply what it does have.

If you are worried about picking up a wheel, and based on some photos I've see of your car I think you might have that issue here and there on high grip surfaces... well that's where more front roll stiffness helps. Keep the tire on the ground and what's the issue?

I really need to learn to just keep my mouth shut. It seems the more and more "experts" that are around, the more and more I end up arguing over what I think are pretty simple things.

thanks.. and understand....Went thru the whole thing, And Tom helped me understand what you were saying. I will proceed with a front bar, hence keeping the Rear end down... more front bar, the greater the pressure to keep the rear end down. .. You know, as well as anybody, that there's always different philosophies to get to the same goal. Both may be right... just takes a different road to get there..
And I know you weren't bustin my balls.. I was just trying to understand your way....vs. my way...thats all..

Its all Good

I have seen nothing that even has me considering a change for any of my other customers (certainly not myself). I keep wondering if I should just build my car all the way, but it's hard to justify since I prefer to run Super Stock and have a pretty good car for it too with 436 hp.

Working on a full build the way I think it should be done with a fellow National Champion as I type this.

EDIT: The Miata Scott Fraser has now won 2 Championships in, in CSP (and top PAX this year) has a regular old Torsen in it. And it's not nearly as much bias ratio either. Just sayin'.

In lurker mode but wanted to make sure accurate information is referenced...

Torsen states a max bias ratio of 3:1 for their T2 (http://www.torsen.com/products/T-2.htm). The NB Miata TBR being 2.5:1. Possibly outdated info though and was re-engineered?

Sam may be surprised but I agree the differential isn't the weak link as money is better spent elsewhere. While in a different car, it does have similar thrust ratios and I'm on a 2:1 TBR factory diff with somewhat good success. A tunable one with the time and resources would be valuable but could easily slow me down as well. If I had the above Torsen though I definitely wouldn't change it, especially for Solo II use.

Not only that. I've never once in an autox situation with this car, the way I have mine setup which isn't the same exactly as yours, had any inside rear wheel spin.

I've done approximately 20 autocross (sort of autocross) events with this car and I actually did experience inside wheel spin once, but this was kind of a Hillclimb in a hairpin turn steeply up hill. (Stock suspension and Koni shocks). (This may have cost me 0.1 to 0.2 seconds).

January of 2013. Really?

What's your question regarding January 2013?
I drove the entire last season and this season with this car.
At the first hairpin at 0:20 of this video you can hear the inside wheel spinning for a split second. At the next hairpin at 0:30 the inside wheel is not spinning and the the rear is breaking out a little:

(Unfortunately the video quality is bad. It was much more noticeable experiencing it first hand. And the road is actually much steeper than it appears on video.)

The question is in regards to you replying to a post that was written almost a year and a half ago.

So people get bitched at for not searching but cant bump an old thread that I am sure they found that way? There is not much discussion on diffs outside of @Scooby South build thread so why jump down a guys throat for giving more info backed by first hand experiance. I respect all the experiance in this thread but more info is never a bad thing.

Jumping down a guys throat? I was merely explaining to him what the reply was in reference too.

I was more referring to the other post. Quoted you just because it was referrencing in case people missed the point.

Because saying that one time you had inside wheel spin in an unconventional situation is worth bumping a 1.5 year old thread for. It's not like he was asking Scooby South for more information on the LSD or something.

[Scooby South]

So what ...the thread is a year and half old. doesn't mean there isn't good information in it.

Update: I have the Guard Transmission Rear diff in my car. It works beautifully. The high quality of the diff and Gaurds setup in the car has definitely enhanced how the car feels and reacts. I am able to stay on the gas longer and get to the gas quicker when I am in a transition, Corner or sweeper. It inspires confidence. It makes me 'want' to push the car even more, which has resulted in some good overall results both locally and nationally.

My 2cents: As a Moderator on the Biggest Subaru Forum (Nasioc) for the last 14 years. I can say that I 'STILL' Reference old threads there. There is still some valuable information in some of those 'OLD' threads..

Well, that was actually the point I was trying to make.
I just wanted to confirm that inside wheel spin happens very rarely (but it can happen albeit in an unconventional situation).

I've been finding lots of valuable information in 10 year old Nasioc threads.
