Two Odd Sounds, what are they ?
1. First sound iv heard since i got the car a while ago. When engaging in a gear or pressing the clutch, there is a *clunk* or shaft play sound. could that be u joints?
2. I changed my shocks out about two weeks ago and everything is good, but is as if something is moving around behind the plastic when i hit a bump,but there is nothing loose back there and the shocks are good. Could that be maybe a wheel bearing ? this just started today...
I checked my speaker and put new screws and still i hear the sound coming from the back left...
getting tired of spending money ha...

Yep, mine clunked when I first got it, and it was the differential mount. As for problem #2, check your shock mounts at both ends. There's a rubber mount at the top of them that can make some noise if it's worn or cracked. If they're aftermarket shocks, some have a sleeve at the bottom that must be used. If that was not used, then they might be rattling around. The dude that replaced mine had to use some extra washers to shim them up a bit, or they would've made some noise. The directions that come with aftermarket shocks are not specific to our cars, so you have to improvise a little.

try some tests. lift the back of the car so the tires can spin freely.
with the engine running and the tranny in neutral do you hear the sound?
does the sound change based on the clutch being engaged or not?
put the tranny in gear and slowly let the clutch out. how does that affect the sound?
shift to second and slowly let the clutch out.. does the frequency of the sound increase?
If the sound isn't there when the wheels aren't turning then it likely has absolutely nothing to do with the driveshaft. if you think it's the driveshaft, get under the car, spin the rear wheels, and try to listen for the sound

I'm still using the factory clutch at 106K. It still feels perfect. No sign of slip or weakening or anything yet. Knock on wood! I took it up to 135MPH today, just for kicks. 
I think it's time to clip the limiter wire. I might want to see what the top end is one of these days. It was still accelerating when I ran out of room. I definitely need to do my brakes! They faded pretty badly braking hard from 135MPH.

It's the purple one that goes to the ECU - #29. This isn't actually an accurate description. This guy isn't all that knowledgeable, apparently. It's not the rev limiter it disables, but it does disable the speed limiter.

Oh yeah, BTW, this is only for turbo's, I think. IIRC, the NA doesn't have a speed limiter. I guess they figured the turbo drivers are more likely to abuse them?
