First HPDE in my 986 - next mod?

[Barchetta]

I ran my first HPDE in my new 01 986 S this weekend, and she felt fantastic. I'm very impressed with the cars overall balance and dynamics. I spent the whole weekend just getting acquainted with how she felt around RRR. I was lucky enough to meet another forum member, Steved0x, and got to talk with him. Thanks for all the info Steve!

So my question is what's a good first mod to help carry more speed for my next DE?

I'm basically bone stock with the exception of Motul 600 brake fluid, and Hankook R-S3's. I've ordered some EBC yellow pads, which will go on before my next track day. I'd like to stick to just one mod at a time between DE's to get it dialed in...so adjustable sways? springs? Techno Brace? or ????

Thanks in advance.
