Lots of questions... - F-Body Road Racing and Autocross Forums

First off thanks for all the help so far, first HPDE went great. Was bumped to intermediate on day two and was allowed to solo, with the brakes smoked lol!

The car will get the following mods before the next HPDE. Car is a 99 six speed z28.

C6 front brakes
Cooling ducts
Pcs power steering pump and cooler
Rear swaybar (maybe)
Bar and belts (maybe)

I will add more questions as I think of them, to start.....

On the brake conversion I will use Kore3 stuff, I already have track brackets... do I use c5 or c6 rotors?
Where is the cheapest source for rotors and Hawk pads? Do I need special rotors such as dba?

What pad do I use on the front? I used dtc30 on front and HP+ on rear with stock calipers Use the same stuff with the conversion?

Cooling ducts....

Cheapest parts source. Do I use the black or Orange hose? Can I use the foglight holes for air intake? If so what do you use to go behind it? If not what duct to go into the air deflector under the car? I will use Blaine Fab ducts on the rotors.

Crotch belt, stock belts and 5 point harnesses with WS6 seats...

Put a hole in the seat bottom for the crotch belt? Trim shop do this? Pics?

To use both sets of belts, anyone seen an eyebolt the same thread as the factory bolt? That way I can clip the lap belts in and out in the factory location. Will that work? Will it clear the seat bottom?

The car does have some push,oversteer. Has a 1le bar on the front and a stock rear bar.what rear bar would compliment the front one? Has all UMI roto joints on the rear.

EDIT....

What underdrive pulley? I was told to stay away from ASP. This should help the PS.

Thanks guys.

It is better, and more importantly, consumables are cheaper (C5 rotors specifically...they used to be about $25 each). I won't tell you not to upgrade the brakes, I think it will save you money on parts and wear items. I am simply saying that I think you should have had more brakes than you did and I suspect you're "beating" on the brakes...which is common at first. You should have had sufficient brakes for a street tire track day and Nape is right, you do have a whole lot of car under you.
