I want to upgrade the suspension to make it a better driving car. This will be a daily driver, no track days for now but I want it to perform well.

I am NOT doing a factory restoration, seeing that I don't have the original motor or trans.

My question for all of you experts out there, I am looking at three options{

Welcome to the best Porsche BBS on earth. You will find lots of good ideas and suggestions here.


A stock 1973 is a fun car. Mine is barely modified and I drive it for fun, on tours, autocross and HPDE.

The only modifications are:
Turbo tie rods (my stock tie rods were worn and the turbos were cheaper);
Upgraded to turbo torsion bars (to address a rear tire rubbing issue, the stock sizes would have been fine except for this issue);
19 mm adjustable sway bars front and rear (for autocross/trackdays); and
A race shop lowered, aligned and corner balanced my car.

I have stock brake calipers and disks with street pads.

I replaced my stock 15" cookie cutters with 16x6 fuchs to get better tire choices and am currently running Toyo R1R tires due to my desire to drive in autocrosses and HPDE's and not wanting to swap tires.

For a pure street car, I liked the Continental ExtremeContact Sports I had previously. They were great for all the things I do but I wanted a bit more grip in exchange for increased NVH.

Option 1:
Stick with the current set, replace bushings, rebuild struts, clean up all the arms, etc. Keep the torsion bars front and back, keep sway bar

THIS IMHO is the correct answer.

Add an alignment, lowering, and corner balance and you are done. Use the saved the money to attend a few Autocrosses and HPDE's to learn the capabilities of your fantastic car and learn critical car control skills. I will guarantee that in stock form you will be hard pressed to exceed it capabilities.

Option 2
Keep the control and trailing arms, add Turbo tie rod ends and change out to a coil over set up for shocks, keep sway bar and torsion bars

Turbo tie rods are ok but the rest is unnecessary for the type of driving you are planning.

Option 3
Go all new on the suspension, 935 subframe with new control arms, coil over shocks, re-enforced shock towers, upgrade sway bar, etc. Get rid of torsion bars front and back I want to add bigger breaks, 3.5" brackets. They will not fit on the stock 73' spindles.

I have been told I can upgrade to new components but am getting mixed opinions. Any assistance would be appreciated

See above. Nope.

All this said, your car, your money, your choice.
