sup.
I have a short question. (I'm still not familiar with my s2k yet)

Could the sudden LSD activation upset the balance of s2k during the turn?
The reason I ask is that..

 

our car tends to get a bit tail happy at times.

 

I think that would be more of a problem with a clutch-packk style LSD than the torsen one in the S2000. The brief stepping out could be a function of your (presumably) quick throttle input rather than the differential's action. Try easing into the throttle more to cut down on the stepping out.

 

From my personal experiences while auto-x'n....

Lets say it is a realitively tight corner, a righ hander, even radius (does not 'pinch' or 'expand' in the exit) 180/hairpin. For arguements sake, with S02's say we can maintain a steady 20mph through the turn. Some people in my region give me a hard time for downshifting into 1st for any corner that drops 2nd gear from vtec. I find that the back end feels more 'planted' if I use 1st to power out/through the corner then 2nd (at aproitiate speeds of course). If I use 2nd, the rear seems to steep out and feels more 'loose' while out there, in 1st I can add more weight to the back of the car by giving it more gas, and generally exit the corner much faster and under harder acceleration.

Also if you do not have/know what youre cars alignment is, that can make a HUGE difference in at the limit adheasion. I have found neg rear camber is youre friend, but not youre tires

OT - but related question - I ran on Hoosiers for the first time last year. In said corner above, it felt like I was getting TONS of inside wheel spin coming out of the corner. Is this a combination of taking ~75lbs out of the back of my car (5.5 lbs exhaust vs. 60 stock and no tools/tire in the turnk) and the gripier tires ? I need to get something to 'tighten' the front of my car to help keep the back planted better? i.e. x-brace or a grendon bar (or whatever some of the track junkies are runing as a lower front sway bar?) Any info on this would be nice so I could gear up for this years upcoming season

 

Go to the Racing & Competion forum. Short answer, yeah with the amount of grip Hoosiers give, you'll lift the inside rear wheel. You'll need to either stiffen the front, bigger sway bar, or soften the rear. You could simply disconnect the rear sway bar but it may not be legal in your auto-x class. An x-brace would do absolutely nothing for this situation.

 

The torsen diff will not let one wheel spin (or maybe just a tiny little bit)

Do what brent said : ease on the throttle.
Youre unleashing a lot of horses @ once

 

The torsen diff DOES let one wheel spin when that wheel is lifted up in the air. That's the downside of our LSD.

 

Quote for truth. That's the nature of the beast.

 

Quote from www.torsen.com

What happens when I have a wheel in the air?

As mentioned above, the Torsen differential is a torque multiplier. The Torsen requires some type of resistance or friction in the system to function properly. A wheel in the air provides zero torque or friction on the system and as the Torsen multiplies the available torque, zero, by its TBR, the end result is still zero. In response to this, we developed the Torsen T-2R with pre-load to combat those wheel in the air situations.

End quote.

Isnt there a difference between spinning in the air (after bouncing off a curb) and inside wheel spin (because of to much torque applied) on tarmac?
In the air there's no friction at all, spinning on tarmac does provide some friction i guess.

Either way.. I stand corrected.
