I have been reading different opinion regarding reindexing the torsion bar when adding coilovers at the rear. I want to keep the stock height and add a set of rear coilovers on my '86 944 NA. Is it a must to have the torsion bar reindexed?
Please, share some experience and suggestions.

Thanks!

 

yes !!!!

 

Yes it is a must..

 

i would ask, why do you want to add coilovers?

 

I must ask, WHY would you want to keep torsion bars, if you are installing coil overs?

Not necessarily,

Just put the car on its static height and adjust the bottom spring pan to just touch the coil springs, i.e. the car weight does not rest on the springs.

In this way the springs are acting only during cornerring or during the down stroke. In needed ,just add a flat low compression helper, to prevent the spring from coming loose during the upwards stroke or rebound. Have 3 cars done this way , and have yet to reindex the bars.

 

Savvas' method works fine, but for best performance indexing is required. Handling tends to be more predictable with the coil springs working through the whole travel. There's a long complicated theoretical explanation for this, but I won't go into it right now. How about trying Savvas' method first, then re-index when you get a chance? You'd need to change coil spring length though.

 

Eliminate the bars
