Hello Steve,
We spoke on the phone last fall when I was on a road trip through your area.
I’m researching suspension upgrade options for my very original car. It’s primarily a street car, and I wish to optimize its setup for the sometimes bumpy backroads we have in the PNW and BC. The car is used for road trips with my wife as well as spirited drives. I might get it to a track once per year to work on my skills. The car has 190k miles on it. Last year we installed new HD strut assemblies, HD shocks, and spring plate bushings. The car already has turbo tie rods which are a few years old. The car was corner balanced and aligned and is quite nice to drive. Criticisms would be that maybe were a bit too low, so it isn’t great on bumpy roads. It’s also looser than I’d like. I owned an M030 spec 944 S2 before this 911 and miss it’s precision.
I’ve weighed the 911 and it is at 2800lbs on a half tank of fuel. Not much change anticipated here.
I’ve read many articles and comments about the necessity of replacing all the rubber bushings. This was not done last year on the advice of the shop, but will be done this year. I plan to also add adjustable sway bars to have the balance tuning options.
Since we’ll be going in again, and have to redo the alignment, I wish to determine if I should update the torsion bars at this time. The advice gathered on this subject varies a lot. Some say more torsion bar and others say stock torsion bars, tuned to be stiffer with the sway bars.
What do you suggest for torsion and sway bar size for my objectives? At what height would you set the car?
Thank you
