You spin me right round, baby right round...
(no, I'm not talking about Erica, thought it's still fitting ;) )

Last month I followed Nugget and equiraptor's example and did a Driver's Edge event at Texas World Speedway. Had a blast, and made serious improvements to my driving. Good enough that my instructor didn't even join me for the last 3 sessions on Sunday, and I was recommended to move to blue for my next event.

So... I signed up for the next event that was available, which is happening right now at Eagle's Canyon. Holy cow, what a different track. This is setup to be a FIA/Formula 1 type track. Lots of straights, but more importantly, lots of *very* interesting corners, and lots of elevation change.

Most important, this course is *very* demanding! You have to be on top of your game here. Almost all the turns are off-camber (meaning that the track surface falls away) and/or have an elevation change. And the course is *very* hard on brakes. At TWS, I could get away with modulating my braking somewhat, which meant that I didn't have to be very accurate on when I started braking for a turn. Absolutely not the case here, and it's been causing me trouble all day. I spun three times today, from screwing up my braking and going into a corner too hot. That's something that an NSX won't forgive you on, especially on this track. To make things more interesting, there's several places where if you go off-track, you're almost guaranteed to hurt the car. I did manage to do just that, though luckily it's just a small paint scratch (I must have gotten a rock between the apex cone and the car...).

Also, the brakes on the NSX are just not cutting it. Apparently, this is a known problem on the "1st gen" NSXes; the front brakes are very prone to overheating. Not only am I boiling some fluid (and this is even DOT4 stuff), but I'm actually cooking some pad material onto the rotors. I'm told there's not really much that can be done for the stock setup, though perhaps I can get it on the lift and find a place for some ducting. Long-term, I'm probably going to have to upgrade, and that means new rims. And in reality, it probably means 2 sets of rims, because I don't want to take nice rims to the track. What sucks about that is if I do that, I want race tires mounted on the second set... but those aren't good for the street, and I have no good way to get them to the track, unless I start trailering the car. Ugh...

On the bright side, I definitely feel like I'm improving. My lines are decent, at least when I'm not dealing with traffic that's unpredictable (this track has a lot of people off-balance...). But I think they're better than when I was at TWS. I've definitely gotten threshold braking down; now I just need to allow myself a buffer-zone so that I won't be going into corners too hot. I also need to get better at adding throttle when the car starts to let loose. I probably could have saved at least one if not all three of the spins today had I done that.

Now I just need to convince Erica to do an autocross... :>

Oh, and Paradox and Leto need to get out here; no excuses about cars not meant for the track! There's plenty of Audi's here (including an S4), and several Lexi (including an SC400 driven on hand controls).

I recall reading a long time ago how somebody managed to fit four race wheels into the car. Obviously one of the rears goes in the trunk. I think the rest of them were something like: (a) move the passenger seat all the way forward, (b) put a front wheel behind the seat, (c) move the seat back, (d) put the other rear halfway into the passenger footwell, (e) put the other front in the passenger seat.

Ha, I found the link and remembered correctly: http://www.nsxprime.com/wiki/Four_Wheels_In_NSX

Sheesh, that's a bit nuts. I guess I'll keep than in mind if I manage to fall into a set of free OEM rims.

Yeah, I should probably write an entry about Erica... But I'd rather spend time with her than on the computer writing about her ;)

But she'll dig it. Blogging about a girl is the equivilant of shouting from the rooftops in love about her ;-)

ps-You, nugget and I need to get together for dinner or something sometime soon.

Do you really need different wheels for an upgraded brake system? Are the rotors already slotted/drilled? Can you not get a different pad material that would take more heat?

I'm sitting in the damp with misting, working the gate at the autocross. Yay for getting my work assignment out if the way.

Yeah, there are still upgrades I can do to the existing system. Pads is the most obvious one. I also want to get the car on the rack and see if there's any way I can get some air ducting in there.

I'm not keen on doing rotors though... I really need to get off the rinky-dink 15/16" rims onto something I can actually buy real tires for. And once I'm at 17" rims there's a lot more I can do with the brakes that makes a lot more sense than continuing to dink with the tiny stuff that's 1st-gen OEM (I actually compared my calipers to a Miata this weekend... mine aren't much bigger).

What's your current wheel size, including width? Different size wheels will change handling and acceleration characteristics of the car, and I'd rather try to find you some good rubber than see you switch wheel size for that. Then again, you can get R6 in your OEM tire size, so maybe upgraded wheels for the street, for better street rubber, and R6 on the OEM for the track. Assuming you don't need larger rotors to keep things cool.

205/50-15 and 225/50-16.

I'm kinda thinking that I am going to want better brakes. Even with better pads, the calipers I have are just tiny; not to mention single-piston. I'm actually a bit more worried about getting good street tires than race tires; I don't care (to a degree) how well race tires wear. But I want at least 10k miles out of street tires, *and* good performance, *and* good behavior in the rain. It's really hard to find that in my tire sizes; and it's also hard to keep it. Every time I go look at what's available for my car, it becomes harder and harder to find something.

Then again, sticking with the same rims will be a lot cheaper...

You do know that when you're at TWS you're about 10 miles from me don't you? Bring Nuclear Tacos. Or at least give me a ring and let's go drink a beer.

I'd need your number, but to be honest I can't make any promises. Track days are *very* tiring; this weekend I was asleep by like 8:30 Saturday.
