I share the same sentiment. However, I don't expect to see a factory LSD available for the boxster/cayman any time soon. Thanks to the weight distribution of the mid-engine layout, slipping the inside rear tire does not occur nearly often enough to warrant an LSD. . . at least that's what porsche seems to think. Whereas, the front-engine Z4M has much less mass holding the rear tires to the ground, and a good deal more power.
If you are willing to spend, quaiffe and guards both have LSD options available for boxsters. Quaiffe specializes in 'torsen' type LSD's that transfer power according to torque , and Guards specializes in 'clutch' type LSD's that transfer power according to relative wheel speed.
The following quote is from a thread on renntech.org by the owner of a boxster with the 'torquey-er' 3.4L 996 engine. . .
Limited Slip Differential, Performance Improvement
"Last Sunday we drove the car for the first time with the LSD and what a ride!
It was the last PCA-LPR autoX of the season with 47 drivers with around 35 cars. The results have not been posted yet but we may have run 2nd and 3rd over all with a ultra light full race 914 in first place. I can tell you there were some 911's working very hard to beat the Monster Boxster. But the real credit goes to the Quaife torque biasing differential, we accelerated faster and corner much faster.
You can view Quaife's web site:
http://www.quaifeamerica.com/
Three parts were purchased from Patrick Motorsports in Phoenix: 1. Quaife Torque Biasing Differential, 2. Side Cover, 3. Bearing. Total with shipping $1,827.51.
This is the best single mod that I have done in terms of performance improvement."

the M Roadster and, to a lesser degree, the Z4, seem to have too short a wheelbase for the weight bias. they seem very twitchy to me and not nearly as confidence inspiring as a boxster. in the M Roadster, i could never shake the feeling that if i lifted off the throttle in a fast turn near the limit, it would spin in a heartbeat. the turn-in was attrociously sharp. some people may like that; i hate it.
i find the boxster, even with a similarly short wheelbase, to be so much more refined both in terms of communication and in balance. it's mid-engine layout eliminates the horrific (IMO) biased short polar moments designed into the Z's.
to me, driving is about the zigs and the zags. the boxster hangs with the best of them. at the limit, i always felt like the z's could ZIG great, but was never confident in their ability to quickly and predictably ZAG back the other way. they just don't feel right to me.

Was racing against one three weeks ago on our national track
was very fast but still look bug ugly!
also M3 on track at same time, seems amazing but probably due to the fact that the driver was very good, saw the same car last weekend on wet track, was a very different story!
test drove the new M5 and this is amazing!push that booster button and waoh! it goes, but too complicated like an over programmed dishwasher, 3 set of suspension and five set of power for each setup. too much hassle!
BMWs are not bad but compare to a real racer like a 911 or a well sorted Boxster forget it.

I hear you. Some on this thread seem stuck in brand loyalty. BMW is a fine company that makes excellent performance cars. So is Porsche. The Z4 M Roadster should give competition to Porsche's Boxster S, and competition benefits all (...or we would all be driving iron-framed, 55bhp cars with solid rear axles).
Hopefully Porsche will wake up, stop trying to separate the Cayman S from the Boxster S, and update the Boxster S with the Cayman goodies to keep up with the roadster competition.

Fellas, what do you expect all of us to say about the Z4? We are on a Porsche website because we are all Porsche-crazy! I dream more about my car than Daisy Fuentes doing Pilates in the nude (which is a recurring dream for me). If you want to be stroked about your feelings with the Z4...go to the Z4 site.
Brand Loyalty: Yes
Think the Box can outrun the Space Shuttle: Yes
Crazy and irrational about the P car: Hell Yes.
Time to visit my car...she has been in the garage for 2 hours by herself....

Rail26, I was wondering if you take alot of crap from your army buddies about your Box and your obsession with it?
It's my impression (maybe I've seen "Top Gun" too many times) that you pilots like to drive cars/bikes that are on the edge as well (I know there are a couple of pilot owners on here). Are there any other sports car drivers in your unit? What do they drive? Or are you the envy of all...
