I used a lower stress bar for a while and thought it made a difference.

How much you'll notice depends on your sensitivity and how you use the car.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

While I rebuild my suspension and drive axle, I thought I would ask: What is the general consensus on strut tower bars to strengthen the Boxster's ride/reduce flexing? Do people notice significant improvements? What about Pedro's technobrace for the rear underside flex? I'm interested in benefits as well as whether or not they are waste of $$! Thanks in advance!
Strut bars will always make some difference. How much you'll notice depends on your sensitivity and how you use the car.
I have all 3 bars (made my own lower bar) and didn't notice any difference when I added them. I have a front bar on my Rx-7 and immediately noticed an improvement in steering response so I think I am reasonably sensitive. The Boxster is really stiff to begin with.
Others say they can tell there's a stiffness increase.

We essentially have the same front end as a 996 Cup car and they don't need/use strut tower bars. Probably not much gain there. The Pedro bar probably addresses the area of greatest flex and the most benefit. I used a lower stress bar for a while and thought it made a difference. I had to remove it for Time Trial competition as it is not legal in my class. The car still feels pretty solid.
I have both front and rear strut braces, as well as a rear lower stress bar (Mantis Racing) installed on my vehicle . Here are my thoughts :
1. Front Strut Brace : Did a noticeable job of reducing some cowl creaks and squeaks
No performance or handling gains .
2. Rear Strut Brace : Zilch .
3. Lower Rear Stress Bar : Imperceptible difference on the street .
Thanks, blue2000s. I plan to find someone to do the alignment and then will install it after that. Haven't checked pricing on alignments or even identified who can do a Porsche alignment (in addition to the dealer!) Any suggestions on good non-dealer alignment services? I read prior threads that some Sears auto centers have done a good job but it seems to depend on who is working there. Any suggestions always appreciated!
With the Bristol Motor Speedway ("The World's Fastest 1/2 mile Oval") nearby, there should be some good mechanics for doing an alignment. I guess it will be a little research. I plan to call the Porsche dealer tomorrow to at least get a base cost for comparison. Any ideas on typical Porsche dealer charges for a Boxster S alignment?
