April 12, 2013 - I've been working on the car a fair bit.
First, I refreshed the shocks by changing the fluid and putting in new seals. They didn't need it, but it's good preventative maintenance. I also fine-tuned the corner weights, did a nut and bolt under the car, changed the oil (7 quarts!) and reset the alignment after the disassembly for the axle change. There's also an obvious change - a new mount for the wing. It's about 5" taller. This location should give more downforce without an increase in drag (or less drag for a given amount of downforce). We'll see how it works out on the local track next weekend. No high speed work, but 75 mph in a sweeper does tell some tales.
I've realized that, with the big change in performance thanks to the engine, tires and aero, the car is becoming needier. I can't just beat on it the way I could when it had the old four cylinder, everything's under much higher stresses and needs more maintenance and more frequent checks. That's why I spent the whole day under the car checking over everything. It's also burning up consumables faster. Nothing like a Corvette, but my tires and brakes don't last the way they used to - never mind the fuel!
It's got two days of hard use at Laguna Seca coming up in a few weeks, and I have to make sure it can run hard the entire time. It failed last year through no fault of my own, but I don't want to give it any excuses!
