After a long cold winter I took the GTS out for a short drive yesterday 4c / 40f cold but the roads were dry. Over the winter months I did several little projects ( Woodhouse mounts, braided SS brake lines, lowered the drivers seat, lower spring caps and cleaned and lubed just about everything.
One mod I did is the one I want to share with GTS owners. My car is equipped with Corsa exhaust and 3:07 gears. The car sounds awesome but always had a bit of a drone. I had also decided to do the mounts as well this winter since the general feel of the motor and shifting quality was not as firm as my Woodhouse mount equipped RT. I was thinking this may make it worse. The mounts were both split so changing them was necessary.
I was thinking that since the car is fiberglass the whole structure acts like a drum. So I removed the interior carpet and lined the entire floor and wheel wells with DynaMat.
Car now feels solid. No drone. Less road noise. Exhaust sound is clear and since I also did the speaker boxes in the back the Stereo sounds better.
Ok it probably added 10lbs to the weight of the car but it was worth it.
Now to bring it to Raceway to install the 3:55's.
