Mach 1 clutch/idle issues? HELP!

Hey I was just wondering if anyone has had to change the clutch on their 03 or 04 Mach's yet...are these clutches very strong and up to par for a little racing? I just got mine and it only has 10,000 miles on it. 04. I was pretty much giving the car a good test run today for about an hour worth of ripping into second and even fishtailing 3rd gear. (the ground was slightly damp). Other than that I dont drive her hard and I never use the clutch unless Im shifting. I didn't WOT and I never wait on the clutch at lights or stop signs. Just a little hard gear chirping fun. Do I have anything to worry about?

Does anyone else notice that their Mach idle comes down very slowly. For example I'm in 2nd gear at 3 RPM and I put it back into neutral. The needle slowly drops from 3 back down to 1 and then below 1. I feel it should it should be dropping more quickly though. Is this normal because of clutch and flywheel weight, or is something wrong with my car? I just got it 4 days ago. Also today after my gear chirping episode at one point for about 3 minutes when I was in neutral and then came to a stop, the idle stayed at about 1,300 RPMs, when normally it drops to about 700. Do all machs do this??

Thanks man, yeah I'm loving it a lot lol. When I was at the dealership getting the car I was on the phone with CJ Pony parts already making an appointment to have a BBK O/R X-pipe and flowmaster american thunder catbacks installed. I got that done today which is why I was ripping it so badly lol, having too much fun; My main concern was when the idle stayed at about 1,400 RPM but it only did it for about 2 minutes I noticed it at 2 red lights, it just stayed at 1,400. but after that it started going back down to about 700 like normal now....

I had an 89 5.0 fox...now that was another story that thing used to get stuck at 2,500 RPMS sometimes and never come down unless i turned the car off... lol i hope she doesnt start that crap....!

I dont have the squeaky noise but I do hear the tranny clunk when I hit the gas at very low RPMs for example if im in 2nd only at 10 mph and i hit the gas i hear it clank n clunk for a second and then it starts picking up normally....i think this is just normal of mustangs tho...my 95 gt and 89 5.0 gt both made the same exact sound...even when at 1 mph in first gear when u first start to accelerate.

Im probably going to keep it mostly stock...nothing irreversable...a few more bolt ons and some radials maybe to put it in the 12s...a short throw shifter probably steeda tri-ax .... louvers and i have the mach honeycomb panel grill between the tail lights...thats about it...i gotta take some pics
