I have a 07 GT 5-Speed. This is a street car. I am adding about 40-50 HP through mods. The car will not be lowered or raised. I would like to install a one piece Coastline Driveshaft. Do I have to adjust the pinion angle whenI install it or can it just be bolted on?

Any help would be appreciated.

i think its just a simple bolt in job, but do not take my word for it.

let us know your results, i've heard great things about adding an aluminum D/s!

I just bolted my right up on stock suspension a/t.

about some websites where you get these? and a story a course.

I just came back in from test driving my car with the Coastline DS. You can feel the launch is harder I could not get in it to much because to many houses around don't need the law called on me. I also installed Steeda's upper third link. I did not check my pinion angle I am going to a suspension shop to get a custom alignment for all the stuff recently installed along with the pinion angle checked. But I can tell you I had no vibrations.

Great to hear the news . It sounds like a winner in my opinion. what is a pinion angle? Also what was that steeda third link?

Steeda's version of pinion angles.






Measuring Pinion Angle

[align=left]Pinion angle is the difference between the centerline of the driveshaft and the centerline of the pinion shaft of the differential.To measure it you must be able to work under the car with the suspension fully loaded and the car level.A drive-on lift works best for this.
Method "A"-(recommended)





Method A (recommended) Use an angle measuring gauge (adjustable protractor) to measure the difference between the pinion flange and the drive shaft directly.These gauges are available for under $10 from a hardware store.Place the edge of the gauge vertically against the front of the pinion flange, beside the driveshaft.Extend the measuring arm forward parallel to the bottom of the driveshaft.Extend a straight edge under the driveshaft to the measuring arm of the angle gauge.Hold the straight edge flat against the bottom of the driveshaft and adjust the measuring arm to read the angle.Depending on the gauge you use, you may have to subtract 90° from your reading to get the correct number.Your final measurement should be between 0 and 5.Examine the diagram at the bottom to determine if the pinion angle is nose up or nose down.

Method "B"





Method B
1) Use a gravity angle gauge (Available at hardware stores) to measure the angle between the driveshaft and the ground.Hold the gauge on the bottom of the driveshaft.Align the gauge front-to-back under the car in line with the driveshaft and read the number from the gauge.Write down this number.
2) Next, hold the side of the gauge against the front of the pinion flange (beside the driveshaft).Measure the angle between the pinion shaft and the ground.Write down this number.
3) Subtract the first number from the second number.This is your pinion angle.Examine the diagram at the bottom to determine if the pinion angle is nose up or nose down.[/align]

This is a good article about pinion angle and suspension.

How do you like the new DS. Do you notice any difference?
