Getting a race seat and harnesses helped me a lot, it lets me feel the car more, especially in my shoulders, and not have to hold on so hard and brace with my legs. Also for me I needed a little extra headroom to keep my helmet from pushing on the ceiling.
GT3 front brake ducts are an inexpensive easy/fun mod
I learned the hard way this weekend not to make too drastic of a change all at once. I didn't crash so that's good
+1 for Clark and Linda at Apex, they are good people and I get a lot of my stuff through them. They are at a lot of events so things like brake fluid (I like ATE) I just get some at the track and save shipping.
Really good to meet you too.
