No drama from the car at all.

Ive never has this problem until my last event. The only difference was stiffer diff mounts and 7 degrees of caster instead of 6. An car has not been balanced in forever lol
Ive ran stiffer front bars, Ive ran no rear bar and I do not care for how the car handles.No rear bar is the worst lol. I run 16k springs (SRCs) now with stock 2002 sways front and rear.
To me the car is perfectly balanced. Ill make sure to check a few things before I pull the trigger on a diff. Lots of helpful info!

Have you dumped the diff fluid yet? Cheap, and worth a look.

Extra caster can definitely cause caster jacking that can make the inside rear lighter and allow it to spin.
A stiffer front bar will help. A softer rear bar will allow more wheel independence. Short dampers or high spring rates that don't allow sufficient droop can cause lift too.

But yeah I will add that an upgraded diff is definitely the business. The response from the rear end when on and off throttle is incredible.

I've often wondered why folks don't do this more often. According to my spreadsheets its totally possible to re balance the car using springs as far as under/oversteer & ultimate grip level are concerned. I am not sure what cons this would bring to the table.

Well for a couple reasons, one of which is not a lot of reasonably priced of the shelf dampers for this car that will control 18- 24kg spring rates. 12-14kg seems to be about it, and thats not enough alone without sway bar for R compound grip levels. You put a 20kg spring on your standard KW v3 and it will feel like a pogo stick, if you can even get it to hold its seals long enough to not blow oil all over your tires and brakes by the end of your session. You can get anything you want if you have enough money, which is what it will take for something like a beefy custom valved Penske to handle those level of spring rates. I dont have 5 grand for coilovers though to control minor inside wheel slippage which I rarely encounter with the stock diff myself, at least at my track, but ive got my spring rates/sways/alingment dialed in for the tires I run. I actually get more of it on the street maneuvering around in off camber road situations. Its not that big of an issue typically for folks on this platform i dont think, which is probably the other reason its not as popular, even though it would yield some broad improvements. The other is that you can do quick tuning changes for free once you invest in adjustable sway bars, and your stuck with what you got and hope its right once you rely solely on springs to do the job. There is no swapping those out in any reasonable way for tuning at the track. So I guess it just comes don to practicality, the benefit versus the compromises.
