Front Torsion bars

wallstreet · 08-21-2004, 10:18 AM

I have a 1970 911T w/48,000 miles. It was sold to me with 14" Fuchs wheels; tires were worn beyond use on the outter or inner depending on side of car. Tire wear is from a bent front strut. I sold the wheels and installed four 6x16 Fuchs with 205/55/16 tires. The vehicle was repaired several years ago; new hood and left fender w/ new headlight. Left battery box will not accept the correct battery; right side will accept correct battery. Front ride height is very high ( 2.5 inch space above tire) on both sides considering the 8mm adjuster bolt is "loose"/no tension on the adjuster plate. If I turn the bolt clockwise, the ride height increases. Is it possible the torsion bars from a previous repair were installed improperly? The repair was made with zero "droop" in the control arm? Can I merely support the body; remove the rear adjuster plate/bracket and re-index the adjuster mechinism with A-arm in full droop? What is the accepted method to install a front torsion bar with regards to droop of the control arm, position of the adjuster bolt, indexing the adjuster plate etc. 101 Projects book on page 162 mentions "A-arm as far downward as possible". What does "as little clearance as possible between adjuster arm and the inside top of crossmember" refer to?

When you install the adjuster arm, be sure to place it on the torsion bar splines so that the 'arm' is closest to the top of the little 'box' in the crossmember. This will leave you with the most amount of available adjustment, assuming you will need to raise the car a bit when you get her back on the ground.

Currently the front suspension is at its lowest; which is very high; the only adjustment is up. When I first viewed "the box", the adj. bolt was loose and the bar was tight against the top of the box. The suspension was in full droop as I jacked the chassis from the very front just ahead of the torsion bar. I will remove the box; leave the susp in full droop and re-install the box leaving the adj bolt loose. This should give me the very lowest setting . I can then re-adj to a euro ride height. Is that correct? Was the bar previously installed incorrectly?

I did adjust the ride height on my 1970 911T. The floor to top of wheel opening was 27 inches. After jacking the drivers side, I place a jackstand under the front torsion bar bracket. I removed the wheel. I removed the socket head/allen adjuster bolt from the "box" at the rear of the torsion bar. I removed the splined bell crank devise from the rear of the torsion bar. Use a large screwdriver or pry bar; you might need to move control arm up/down to assist removal. Upon inspection, the rear torsion bar seal needed to be replaced. With the bell crank removed, I jacked the lower control up from under the ball joint to 15 inches from center of spindle to upper wheel house opening. I replaced the bell crank on the rear torsion bar to "zero" adjustment in the "box"; approximately 10 O'clock position, replaced the allen bolt set to 0+ adjustment (finger tight), removed the jack from under the ball joint then replaced the wheel. I removed the jackstand under the front torsion bar bracket, set car on the floor. The 15 inches moved to 12.5 inches and the floor to wheel house opening resulted approximately 24.5 inches; depends on tire diameter. I had full upward adjustmet on the allen bolt adjustor.

Questioions: What thru body stabilizer bar is available and what size for street/mild performance use; OEM or aftermarket?

Anyone know if the 944 Turbo calipers fit the 911 brackets? bolt spacing and back spacing?

I bought an aftermarket thru-the-body 19mm sway bar. If you can locate a '76 Turbo used bar, it will fit and will be 18mm, or so I am told.
