I made a few changes, some from personal preference, some from necessity. I kept the ride height even at 100 mm front and rear (I don't like uneven ride height), used my own transmission settings (I forgot to write yours down), and tested the setup on N2 tires to get a better feel for its handling. I also picked up the rigidity refresher, since you didn't specify whether you did or not.
Very nice setup. You've struck an excellent balance between quick response and stability over bumps (what few there are on Suzuka). However, it's a little understeerish for my tastes, especially under braking (a common TVR trait), but also during tight cornering and a little bit under acceleration. I would suggest the following:
1- Ditch the limited slip. The Cerbera has excellent traction on its own, and your current settings can't get much lower. This is the one change I'd suggest you try even if you disagree with the rest of what I say.
2- Adjust the brake balance more to the rear. I set it to 6F/9R to test, and that helped quite a lot. The slightly lower overall power level helps counteract wheel lock on new and worn tires, too.
3- Make some minor adjustments to the spring rates and stabilizers. I went with 10.1F/9.8R for the SR and 3F/4R for the stabilizers. I also tweaked the bound and rebound to suit my driving style.
After I ran a few laps on Suzuka (two practice laps and 2 Family Cup races), I headed off to the Nurburgring to really give the suspension a beating. For as low as your ride height is, your setup handled the 'Ring admirably. There were some hairy spots when the car wanted to jump-n-bounce, but a little forethought and light braking kept it calm. The hint of understeer caused some problems here and there, too, but nothing bad enough to make the car unenjoyable.
I ran a 7'55.8 on N2 tires- a very respectable time for a lightly tuned production car. For comparison, I ran a lap in a stock BMW M5 (arguably the best 'Ring car in the game) in 7'56 and a stock TVR Tuscan in 7'57, both on N2 tires.
Have fun.
I used a DFP during testing, just in case it matters.
