Probably 1000 street miles actually.

 

yikes. what fluid? was it break-in? is it making noises?

 

Is that a brand new diff? Was it changed at 500 miles?

 

Not a new diff, like 4 years old. Makes all the wrong noises for less than 5000 miles, and yes it was broken in properly, and then Mitsu rear diff fluid was used with slip lock. I think it was just the extra power that I was making, without upgrading the fluid to something a little thicker tbh. Around 650-ish. I'm thinking I'll just buy another one.

 

Gotcha. I'd definitely send it back to Jon. Curious as to what happened.

 

I've got a Wavetrac front diff with Shep 12 plate rear diff. On track the car handles awesome, granted I haven't been on anything tight like hairpins yet. Autox isn't much fun, but I think most of that is due to the suspension being way too stiff, lifts wheels in most tight corners and results in tons of plowing.

I've previously thought about moving to a 1 way diff in the future but I honestly don't think it'd make worlds of difference on a car like mine that's setup for the track. For autox I can definitely see it being beneficial but with most tracks being much less tight and with how well the rear locks on my car already I don't think the benefits outweigh the cost and rebuild interval for something like a Cusco.

 

I always thought AX cars had the stiffer suspension. I run soft (road course) rates and just can't keep up, in slaloms, with the AX guys at the events I go to.
And I think we all tripod our cars, regardless. That's just Evo

 

I've got 10k/12k springs. I suppose it's pretty common for evos. But yea, LIFT ALL THE WHEELS

 

there's a lot of great clubs in the chicago area -w hich event did u attend

 

For autox or track?

 

autox

 

All the autox I've done in the evo was either in MI or down in STL. I've run with a couple groups in the chicagoland area in my old 135i. Only group I can remember was Salt Creek, been a few years since I've done an autox in that area.

I've owned miatas for a few years now and just did my first autox in one last month lol. From here on out I'll probably use the miata for autox and the evo for the track.

 

which clubs in STL? I'm actively involved in SCCA down here.

Never heard of salt creek, but chicago scca & tsscc both put on some really good events. none of the tight **** you'd see at like windy city miata club

 

Can't remember what club. I was with a bunch of Mazda buddies, it was hosted at Gateway Motorsports back in August. Was a pretty fun course til I toasted a rod bearing

 

That's definitely more of an "all around" spring rate setup (I have the same on my Ohlin's). Most dedicated track guys you'll see running stiffer, like 12k/14k. Autocross guys have been known to go even stiffer..
