radiator hose issue

I have the big Griffen radiator and am still running all the factory hoses with a worm clamp on the driver side connection. Its this lower driver side connection that is leaking. Its a slow leak, it only causes problems at WOT...if I do several consecutive runs on autoX or I do a WOT 1/4 type run it spikes and won't cool unless you park it for 30 min. This is as a result of a low coolant level. I check it after these occations and it is always low despite having recently topping it off. I guess it is leaking more than I originally thought. What type of hose/connection can I replace the factory setup with that would prevent leaking? Id like something plug and play that doesn't require fabrication if possible.
Any thoughts?

Removing cone marks from a white car

What is the best product or technique to remove cone marks from your car after autoXing for a weekend. I have several marks in various places (LOL) and I'd like to remove these without too much abrasion on my paint.

Another driving critique post

Help me out with suggestions here in the autoX. NOTE: my front tires were pretty much done at this point (4th event on the NT05's in addition to street miles).

Home made brake cooling ducts

2002 Camaro SS. Does anyone have a good idea and source of parts with which to fabricate some brake cooling ducts? I am looking for stuff you could fabricate or pick up from places like Home depot or Lowes (if possible). Something that is functional and can be done cleanly and affordably. I planned on going thru the openings in the grill (drill out the foam) and run flex tubing from there to the wheel well (cut a hole in the liner) and shoot the air to the rotor. My 295's fill up the wheel well pretty well so positioning will be a little tricky.

Any thoughts?
