I've been a Maxda RX8 driver for 4 years and I think it could be better at cornering than the CS that I'm just about to take delivery of. In fact, ny practical experience in chasing CS's on and off the track is that it is. Any opinions?
There are not many Caymans in the UK.... (Fact)
There are not many Caymans in the UK that Venture onto the Track (Fact)
The Caymans that go onto the track we know (Fact)
As just one of the Caymans that do spend a lot of time on the UK tracks - We have never been passed on any track by any Mazda......
We Pass most other cars on the track - Because the 'Silver Bullet' and the 'Yellow Peril' are driven by Sad Fat Old Gits with no respect for horsepower, cost or any other variable as we hit on anyone and everyone.
Our Caymans, will Pi$$ on most cars on the track, except real exotic race cars..... Radicals etc (We especially like to Pi$$ on expensive Porsches - GT3's and the like driven by anybody ....)
Come out to Castle Combe on the 26th September............ And see the results for yourself..........

Lawrence summed it up accurately: Double wishbones give you less camber change during hard cornering and a lower roll center. (More points of articulation) My educated guess is that with enough spring rate, you often don't see enough roll during a corner to push the suspension far enough along it's range of motion to impact camber though. However, double wishbone has another serious advantage, and that's its lower profile packaging. (Better C/D)
Now, the issue no one has really addressed is one of simple semantics: Handling needs to be defined. In my book, and that of Car & Driver, handling encompasses a lot of factors, some of which are very subjective. "Grip" is a more accurate term if you're defining all out lateral acceleration of the car. In the latter case, with tires being equal, there isn't much difference between the all out grip of a Corvette and that of a Cayman. Both hover right around 1.0 G. However, the handling is significantly different. They don't turn in the same, they balance differently in a steady state corner, etc... The subjective handling difference is often far greater than the actual difference in grip between two cars.

Motor Trend's October 2008 "ultimate handling" guide article tries to put a bunch of quantatative data and analysis behind this point, followed by a "subjective" ranking done by Randy Pobst ~
Wish they'd included a Cayman as one of the test cars for their comparison.
Wait a second, they did (at least indirectly) include a Cayman comparison, along with that of a Porsche GT3 and Corvette by way of last year, 2007, best handling car comparison, http://www.motortrend.com/features/1...car/index.html albeit driven by Max "the Ax" Angelelli instead of this years Randy Pobst.
That said, for those claiming 1.44 ~ 1.46 laptimes at Laguna Seca, you're doing pretty well. Max the Ax was only able to claim a 1:47.577 in, I assume, an otherwise "stock" 2007 Cayman S. As for the Mazda Rx8, and Honda S2000 comparisons, Max the Ax in the S2000 reported a 1:50.738; Randy Pobst in the 2008 comparison ran off a 1:50.418 in the Mazda Rx8 and a 1:40.920 in the new Audi R8 against a 1:40.453 for the Nissan GTR. IMO, so far the Audi R8 is a "no drama" 1:40 kind of lap.
Yeah, that was actually Motortrend. I enjoyed their 2008 comparison, aside from the self-admitted editorial bias towards the GTR, the data was quite fascinating. Especially the information on how a car transitions from steering inputs to a full suspension set in a corner. Loads of very nuanced facts and figures.
you got it backwards. unequal upper & lower (wishbones, whatever you wanna call them) controls arms GAIN more neg camber in compression. thats why you need more static camber with a strut type suspension to compensate for the lack of camber gain. Also, you can put the roll center anywhere you want (within reason), whether its strut or wishbone suspension. the advantage is the roll center moves around less with a wishbone suspension as it goes through it's travel.

There are loads of caymans up her in the Kings Country, we have loads of caymans esp in Aberdeen. That fact aint very true. IMO

Wow, they really liked the 2007 Guards Red Cayman S in the Motor Trend article comparing best handling cars.
Does anyone know if they tested a Caymen S with or without PASM. Of course, I'm hoping it was without PASM since I bought my used Lapis Blue Metallic without PASM.
PASM - Porsche Active Suspension Management
This active damping system offers continuous adjustment of individual damping forces based on current road conditions and driving style.
The driver can choose from two setup modes, ‘Normal’ and ‘Sport’, using a separate ‘damper’ button on the center console. ‘Normal’ mode is designed for general road driving and circuits with uneven tarmac. ‘Sport’ mode is intended for smoother track surfaces, where the harder settings help eliminate pitch and roll.
In either mode, PASM continuously evaluates the current conditions while automatically selecting the corresponding damper rates from the respective set of mapped values.
A range of sensors are used to monitor the movement of the body under acceleration, braking and cornering maneuvers, as well as on poor road surfaces. The PASM control unit then evaluates this data and modifies the damping force on each individual wheel in accordance with the selected mode. The result is a significant reduction in body movement as well as a better grip on the road.
For example: if ‘Sport’ mode is selected, the suspension is automatically set to a harder damper rating. If the quality of the track surface falls below a certain threshold, the system immediately changes to a softer rating within the ‘Sport’ setup range. When the quality of the tarmac improves once more, PASM automatically returns to the original, harder rating.

I have owned a Mazda RX-8 for 4 years. 3 years the car stayed stock and the last year I toyed with the suspension and other modification. I have left my lovely RX-8 to be with my Cayman about a year ago. I did keep both cars until recently. Let me assue you the RX-8 is one of the funnest cars you ever drive. It is so stable and so neutral and until I got used to my Cayman I was driving the RX-8 faster around the track. Only issue with the RX-8 is the power. It needs to be in 300HP rane, and you will have a hell of a car. After owning the Cayamn for a year I would you can't beat a mid-engine car, and I would not want to go back to a Mazda again, but I would not mind picking up another Mazda in the furure as a second car. I am wiating for the new RX-7 to arrive (and hopefully) with 4 seats like the RX-8 then I will present my case to my wife of needing a safe family car like the RX-7. Currenly I have the Cayman S DE1 and she has the Boxter S Spyder RS 60. A faimly car would be nice to have soon!!
