Well I didnt order the TA just a new bushing for now. If that doesnt get me where I need to be Ill order a TA or hope Speedinc has one in stock I can grab fri morn and put it on b4 I head out to RSD.

Also if Im reading the finder right Im at -6.5* right now correct???

The way I see it your pinion angle is positive 3*.

So your subtracting instead of adding them? Which way is positive and which is negative on the finder?? In the BMR vid it says add the rear end number to the DS number to get your PA? Then he says both were negative while talking but the angle finder on the rear had the needle pointing to the back of the car and the on the DS pointing to the front of the car.? **** Im confused now.

Throw the angle finder in the trash.

Go to sears and buy this - http://www.sears.com/shc/s/p_10153_1...u=00948295000P

It's got a magnetic base and makes it easy. Shows if it's going up hill or down hill.

No more guessing.

Do you have an Iphone 3GS or Iphone4? You can download a free level app. I used it for setting my driveline angle.

I have a Thunderbolt 4g.
People have been using these things forever. I just need to make sure Im doing it right. Both the rear and DS seem neg to me since they angle up towards the front of the car. Then BMR says to add the two numbers. Thats how I came up with -6.5. Both readings were looking from the pass side. Is this not right?

You drive line is pointing down towards your rear end at -2*. Your pinion is angle up towards your drive line + 5 degrees. -2 + 5 = +3* angle. Set your TA bracket to 0 and you will be at -2* which is about where you need it.

Thanks! So you dont think I need a new TA since I can adjust the front? Ill give it a try when the new bushing get here.
Thanks Jon Ill give ya a call as soon as I have some free time at work today.

I don't even measure the driveshaft angle when measuring the pinion angle. For the most part unless you drastically lower or raise the suspension, it doesnt matter for our cars. First you should do is level the chassis of the car. Then you can take the measurements without having to factor in for the ground not being lever. Then put the angle finder on the rear torque arm bracket and set it to 2 degrees downward towards the front of the car. This will make a slight v between the driveshaft and rearend.

You need to have the TA bushing installed to set it right. You don't want to adjust the pinion angle by moving the front mount because that will change the instant center. This is why you really need the adjustable TA. That way you can adjust both.

Did you check the driveshaft yoke when you were under there?

Just thinking out loud but could the radials be picking up enough mph causing him to have to shift?

Mike you need an adjustable TA for sure to get the suspension in order. I measure mine just off the rearend pinion @ -3.

My A3 4.10 28x10.5 150 shot shift at 7k setup went 134 (maybe up to 137-138) and I still had room. Your clutch is slipping or something, you should be able to go well into the low 130's in 4th gear.

New bushing is in, and I ran out of time so I didnt pull the DS. I did notice when lifting the car onto ramps the yoke did slide a bit same when I pulled the trans mount to get the new bushing in. Ill pull it tomorrow since I have off work although it doesnt appear to be binding. Car is up on 4 ramps so its about as level as I can get it.

I dont think so.
Will order tomorrow. Wish you were still at Speed to put one aside for me. lol

If the clutch was slipping wouldnt it be worse on spray?? Car still went through in 4th on the bottle. Im thinking since the car was bogging so bad in 1st it was making first gear useless NA. On spray it would do the same but had enough power to almost pick up again in 1st. I dunno just my guess but the clutch seems fine in all other circumstances besides NA passes.

Anyways The new bushing is in and I moved the TA to the bottom holes in the bracket.
Angle finder read 4 with the needle showing to the left of the 0 on the rear
and 1 with the needle showing to the left of the 0 on the DS.

If your reading it from the passenger side, and it reads 3 to the left on the pinion Id say your pinion angle is -3*. Ive never taken the drive shaft into equation and I dont THINK madman does either.

Most driveshaft companies will tell you to measure it that way also. Otherwise you'll get vibrations. One thing you do need to take into account though, is how level the car is. Most garages have some slope to them so that water cant come in the door. If you have say 2 degrees of pitch on the floor and set the TA at -2 it isnt going to work right. I would put the car on the ramps, then use a floor jack(or two) to level the chassis. Then set the TA to -2.
Putting the front of the TA that low will probably hurt you because the instant center will be lower,shorter.

Going to pick up a short length TA with DS loop now. Anyone want to buy a full length non adj TA and lakewood DSL? lol.
25th Would it really matter if the floor was 100% level if you use the DS & PA measurments? Wouldnt really matter as long as the Rear to DS formula came out neg 2?

355z thats what I thought also. Are we wrong here?
