Change to clutch pack LSD or not
So I have a problem that I dont really know how to address but Im leaning towards a clutch pack LSD being the solution.
Basically, the car is kind of stiff (12k springs all around), has quite a bit of aero (estimating around 400-600lbs total or something in the ballpark of that), stock power, entry level R compounds levels of grip tire wise.
On to the problem itself, when the tracks are smooth, its mostly fine, but on some turns, or in really bumpy tracks, when the car hits a bump as I start to accelerate or if I hit the kerb too hard the car will struggle to accelerate smooth and just go up and down in rpm, which Im assuming is the inside wheel spinning freely, or close to anyways. When it does so, the car understeers on turn exit instead of getting the nice rotation I like so much when its just sliding both tires towards the exit. When this problem doesnt happen, I can take most turns with very little steering input and have to even add a bit of counter after I hit the gas, but when the stuttering happens its just understeers and I usually just have to back off or dab the brakes a bit to not run out of track.
The car doesnt lack power to spin both wheels on corner exit, provided im at the very edge of traction, I think with even half the power I would still slide the rear on corner exit, but it only happens on smooth tracks, on bumpy tracks corner exits are frustrating and filled with transitions between under and over as if the car is suddenly losing half its power. What I think the solution is going to be is a clutch pack diff, thinking of an OS-giken specifically. To have both wheels get all of the power all the time, regarding of one being 1 foot in the air or not.
What do other people who have been down this path already think? Am I on the right track? I havent really experienced this before so Im not sure if it is what I think it is. In the ruleset that we use, there is no difference between a torsen or clutchpack type diff, so I would incur no penalties for switching out, so if there's time to be found there, Im totally taking the dive. I know this problem can be driven around, but I'd rather solve and find time if at all possible.
