I also replaced my brake lines with teflon/ss and used DOT 5.1 AP fluid, so from a braking perspective I think I am ok. I ordered my helmet last nght (AS 2005 open face). It's going to tough waiting till March.

If you're at the track, saving brake should be last thing on your mind. You should try to find the perfect combination of downshifting and braking during turns. For example, some track will have 5-4-3-2-1 markers by the turn. These numbers are GREAT for finding your perfect time to brake/downshift. For example, after a long straightway, you can mark no. 5 at your braking start point and 3 your downshift point and see how you like it. Then if you think it was too soon, you can change no. 4 to braking start and 2 to downshift etc.
Nice brake lines! I think DOT 4 is better for your ABS. Here's a post from this thread:

If you're careful, you should be able to drain, flush and bleed with new DOT4 and use 2 quarts. Don't use DOT5...that is silicone based and is not compatible with ABS brakes. DOT4 is fine with ABS. DOT4 has a higher boiling point than DOT3, and therefore is more performance oriented. Likely overkill for most, especially if your car remains on the street 100% of the time, but if you want to splurge a little it doesn't hurt. Keep in mind, some luxury brands put DOT4 in their vehicles from the factory, eg. BMW, Mercedes-Benz.
In my opinion, if you can afford a good quality DOT4 go for it. If not, a "house brand" DOT4 is likely better than a DOT3 fluid.
