-- I also have the sport pkg LSD and I was curious whether or not I would really need to upgrade if I went with 4.08 gears.

The problem with the OEM VLSD is that it easily overheats & performance falls off fast & will eventually burnout leaving you with 1 tire fire syndrome. I like solutions like the gear driven units from Wavetrac & Quailfe over clutch pack solutions which require more maintenance & most of the time special friction additives. If you are a person who likes spirited driving thru the twistys, the Wavetrac & Quailfe are great options. For competition clutch packs are more positive in their engagement & if it's a drag car nothing beats a spool.
if you are looking for more drive out of the corners, an aftermarket diff will be an improvement over the VLSD
If it had been out when I did my Quailfe & gears, I would have opted for the Wavetrac as it has an advantage as it is able to be tuned.

YMMV
