What part should I get to improve the handling?

[JWC]

but so far I only see Quaife LSD for my DCT. There is no any option out there...

What's wrong with Quaife?

Any thoughts on the Dinan LSD ($1600+install) compared to other options, such as a custom LSD from DiffsOnline or Performance Gearing?

Best way to go faster is to spend your $$$ on quality driving instruction.

Nothing !
It's the best mod you can get.
Tires + LSD are the must-have IMO.
The car gets so much better in any curve, you get an increased traction on all slippery surfaces.
Moreover, I haven't seen one single person disapointed with the Quaife LSD.

I have a Wavetrac and I love it. No doubt I would love Quaife too.

But if you want to see people who are disappointed with Quaife, just look in a Porsche forum. They're used to OS Giken LSDs, so when they try Quaife or anything else less aggressive than OS Giken, they are very disappointed.

Camber plates make for the biggest handling increase. Rear subframe bushings make the car feel much better, but not necessarily go any faster around a bend...

We had a recent discussion here on the E93 front sway bar. It may be a bit stiff and introduce some unwanted understeer. Some like it, others don't. Maybe compromise and get the E92 M3 front bar instead? Or hold off alltogether and wait until you've driven your car with camber plates to see if you still need the sway bar.

Any camber plate/lower springs combo you can recommend? Sounds like cheap enough for my sort of budget level...
