Got a track related question? I'll try to answer.

I'm planning on getting some Hawk HP+ front and rear pads for track days, and then swapping back to the stock pads for DD. I was wondering if it is ok on the rotor to swap pads like this. What do you think?

If you're swapping pads, I'd recommend you get something more aggressive. If you like Hawks, try the DTC60/70.

Otherwise, Project Mu Club Racers are excellent, as are Carbotech XP10.

Stick to the higher end, to prevent sidewall roll over.

Thanks man, I'll look into those.

Another question, is one bottle of ATE TYP 200 DOT 4 Brake Fluid (1 Liter) enough to swap out the stock brake fluid or should I get more?

I'd recommend a minimum of Motul RBF600. ATE Type 200/Superblue will not really stand up to these pads.

RBF600 < RBF660 < Project Mu G-four < Torque RT700.

We use Torque in our car, but Project Mu G-Four is popular, because it's green, and turns dark/brown as it ages, giving you a visual indicator of when it needs to be changed.

Thanks! Since RB600 and RBF660 come in 500ML bottles should I purchase two of those to completely swap out the stock fluid or is one enough?

Ran NT-01's for the first time (after my PSS' were corded) and was impressed by the grip, but could not beat my personal best on the PSS' at my home track; Sebring.

Looking at the data from Harry's in Excel, in a Speed vs. Time graph, I noticed for the most part cornering speeds were higher and I was getting onto the power sooner, however for the big straights, I was down a few MPH from my fastest lap time with the PSS (see below).

My 2:39.13 on PSS' was back in Jan when it was a cool 55*f, and my 2:39.15 on NT01's was in about 80*f weather in March. Only other change since Jan was modified snorkel and drop-in filter.

seems like a clear description of more grip in a car limited on power.

time for NOS!

You'll need 2 for the initial flush, and 1 or 2 for each subsequent bleed.

THat's precisely why we go with a smaller tire

less rolling resistance matters a lot for our cars.

25 degrees of ambient can easily account for 2-3 mph top end.

Mike, I went from a 215 PSS to a 215 NT01

@King Tut helped me do a flush of my brake system yesterday (thanks again) and he was able to bleed all of the lines twice and still have a bit left over of my 1 L bottle.
