I have '74 911RS front suspension in my car and was wondering if anyone knows what the OE torsion bar size is on that? Thanks, John

Aaron-- did not see the RS it came off of. This was info from PO. Has S calipers on vented rotors. Would the spindle height be different on a 74 911RS? I could probably confirm the actuallity of what it is with that info.

It may be a standard 74 911 front suspension-- would that be 19mm T-bars as OE for that year? I just would like to know what my set up is without tearing it down. If I pull the t-bar cap off would the t-bar have a number stamped on the end like the sway bar does?

19mm t-bars were used in ALL 911 front suspensions
AFAIK the RS had stock front suspension except for the alu S calipers |

19mm up front and 24mm in the rear. There will be no number. You could simply slide it out far enough to put a 19mm wrench over it to verify.
For the most part, a 74 RS suspension would be the same as an S suspension of that year. They should have Bilstein (green) struts with S-Calipers (aluminum). The spindles should be standard. I believe the 18mm raised spindles were an option on some 73 cars to homogulate the RSR for racing. I'm guessing that in 74 that was gone. I use stock t-bars on my RS clone with 930 sway-bars up front (1976 only) and in the rear. I also added the 930 rear torsion bars (26mm) because I upgraded to a 3.0 engine with similar power. The 26mm bars should help eliminate throttle squat. |
