Just about finished with torsion bars... quick question


Recommended Posts

Before I reinstall this giant assembly, I'd love to know if I have the plates near correct as I did have to make a huge ride height change. Initial rear ride height was 8.5" to the rocker... so I wanted to drop it 3". That combined with all the other measurements(23.5->30 mm bars), and Joe's spreadsheet spit out a total delta H on the bottom line of -4.875 inches. That seems like a ton as my original measurement was 8.375" from banana plate to the top of the funky flat thing on top of the trailing arm. Closest I could get was to about 3.5" so I should be close.

 

The result is that the banana plate just seems really close to the trailing arm. For anyone else having done this, does this seem correct? I really don't have the time to drop this thing out again... that just might fuck up my schedule BAD. Comp School is next friday. Ugh.

 

Also realized last night that torqueing the axle half shaft bolts without a parking brake is gonna suck too.

 

I'm off to the trailer store. Have a brand spanking new 17 foot trailer awaiting me. Wish me luck, I'm gonna need it this weekend. Burning the midnight oil trying to get the car ready for school.

Well, got the car down on the ground and it looks like I'm a bit short. 4" at the rocker.... and I need 5" minimum. Looks like I get to go two notches up. Crap.

 

Thought it looked a bit short.

Most of us in 944 spec run about 4" to the rocker. Sorry.

No worries Joe... stayed in the garage until 1130 last night and got it a bit better. Now it is a touch higher than I wanted... ~6" as opposed to 5.5", but I am not doing that job again. I might try to adjust the eccentric a bit but for now I have a ton of other stuff to do. Good to know that 4" is not TOO low though.

 

Will post pics next week or two... right now life is mega crazy trying to get this thing done. I'm almost there... wish me luck cause I need it.

You should be able to get 1/2" from the eccentrics

We just did my car it the VFC engeering shop in Chicago. We ended up not using measurements to adjust the ride height but an angle gauge. What we found out was the angle needed was 3.5 degrees positive puts the car at the proper ride height. We did this with the weight off the suspension. It was much easier than the measuring we were trying to do.
