I'm getting wicked diff chatter under hard corners on the autox corse. May be a dum question but I don't think it should be this loud. I understand it's a lsd do I need any additive?

 

Stock torsen or?

 

Sway bar? If so small fortune racing 1.25 solid front and 1 hollow rear, or the rear diff which is stock 07 rear end

 

Something may be wrong with your diff then, if its stock.

 

i changed the fluid 2 weeks ago and didnt notice anything strange out of it and it was doing it last year too but wasnt sure if it was normal

 

any input?

 

If its the stock torsen diff then something may be wrong here as they shouldn't really be making noise. If something is wrong and you decide you want to rebuild with an upgraded unit we just went live with a group buy for the OS Giken super lock LSD today- https://www.s2ki.com/s2000/topic/112...ken-group-buy/.

I have now trashed two of the stock torsens on my AP2 after countless track days over the past 3 years. I was always interested in the OS Giken unit because it is arguably the best LSD available for our cars- it isn't that much more expensive than the stock LSD but it should provide some noticeable gains and more importantly for the average Joe, be a much more reliable unit.
