Alright guys,

I just got thiscompletely stock '90 GTU with less than 90k miles. I have some questions about the car which I'm not sure if its just normal operations.

When I turn, theres a squeeking sound that I can hear from inside the car. I'm thinking its the CV joints but would like to hear other opinions.

When I brake, theres a squeeking sound too. I'm intending to swap out the GTU's front and rear calipers to the turbo version. I know the turbo's front calipers are differnet than the NA ones, but how about the rear? Are they worth the money? If I do this, will I be using the same rotors?

The car's rpm fluctuates about +- 100 rpm during idle, this becomes alittle more noticable when I turn on the AC.

The shifter feels kinda soft. Will putting in a short shifter fix this?

When sitting in my car, and I bounce in the seat to shake the car alittle, I can hear a soft squeek.

When moving off from a stop, the engine vibrates alittle more than I'm comfortable with. Will changing the motor mounts help?

My radio antenna is loose, I can move it up and down with my hands, but in the car when I turn off the engine, I can hear the motor working. Is there a pictoria instruction on how to fix this?

When I start the engine, the oil pressure gauge is in the middle (horizontal) and the temp guage is also in the middle. Is this normal?

And lastly, for now, there's this white/clear light? right under the flip-up headlights. Are they suppose to work? I can't seem to find the switch to turn them on.

Please advice on some or all of them.

Thank you!
