But if the diff moved first it could explain the axle, like you said. I'm not sure if your posi would lock or open when one side is essentially gone. Someone that understands them better can correct me.

Those diff mounts took a beating too, wonder how much if any they were allowing things to move under load. Guessing it's more likely the strain did a number on them after the breakage occurred.

It'd become instantly open.

Unlike my jeep locker which is a locker a LSD won't lock unless both axles have pressure being applied. It takes something like a detroit locker or physical engagement to change that.

Are you 100% happy with the 275/40/17 NT01's on the rear? I was thinking about either going with those or trying to source a pair of the 949's (17x10 rear) and running a 315/35/17 in the NT01. We have a local guy here running the 315's on his and all that was required was rolling the fenders. I really hate to change my wheels out... but I would like as much contact patch as possible. What power have you been able to keep traction with the 275's?

Thanks for the feedback and nice set-up

I was explained the absolute limit in the rear was 295s giving just 1mm inside and outside for clearance. Can you perhaps point me in the direction of someone fitting 315s without over fenders? I'm look at at custom RPF1s to accomplish even 295s right now but the NT01 is a 315 and I'd love to have that option. Thanks much if you can point me to him or a thread on that.

You won't be able to fit a 315 on the RPF1's. Enkei only offers an offset of 38mm for the 17x10 and you'll need flares for this application. If you want to run 315's with only having to roll the fender you will need something along the lines of a 72 offset in the rear on a 17x10 rear. The problem is that 949 no longer has the wheels in matching sets available. Anything else is going to be on the custom side or be a Volk/Work wheel that will set you back at least $3,500. I already have Volk 17x9's on my application which is why I hate to get rid of such an expensive wheel... but I'm a believer in function over fashion as well. However, at some point, a street tire is only going to be able to do so much.

If you're happy with the 275's on these settings then I may ditch the idea of going with the 315's. As I said before, there's only so much a street tire can do.

Yes, this is why you grab the 9.5" and have it widened custom to 11.5" adding both inches to the INSIDE so the offset becomes more like +70 or something like that. Though the guy who did this already found just 1mm on the inside and outside of the rubber in terms of clearance so I can't imagine how a 315 would fit. He used a 11.5" made from the original 9.5 + 38 to accomplish this.

The custom widen ran him 200 per rear wheel to accomplish this, much cheaper than volks of course.

Do you know who the person was fitting 315s?

Can't wait to see vids of this beast making some passes down the track. Very nice build Matt.


...


By the way, if anyone is looking for 17x10 rears to fit under the stock fenders, I'm selling a nice set of custom iForged for a very reasonable price: https://www.s2ki.com/s2000/topic/904...ed-fs6-wheels/
