If you are going to do GT3 seats, do it right, color coordinate!   |  |  |  | | LSD - Limited Slip Differential |  | A limited slip differential (LSD) is a modified or derived type of differential gear arrangement that allows for some difference in rotational velocity of the output shafts, but does not allow the difference in speed to increase beyond a preset amount. In an automobile, such limited slip differentials are sometimes used in place of a standard differential, where they convey certain dynamic advantages, at the expense of greater complexity.
The main advantage of a limited slip differential is found by considering the case of a standard (or "open") differential where one wheel has no contact with the ground at all. In such a case, the contacting wheel will remain stationary, and the non-contacting wheel will rotate freely– the torque transmitted will be equal at both wheels, but will not exceed the threshold of torque needed to move the vehicle, thus the vehicle will remain stationary. In everyday use on typical roads, such a situation is very unlikely, and so a normal differential suffices. For more demanding use however, such as driving off-road, or for high performance vehicles, such a state of affairs is undesirable, and the LSD can be employed to deal with it. By limiting the velocity difference between a pair of driven wheels, useful torque can be transmitted as long as there is some friction available on at least one of the wheels.

I think the set was $7-8K, the titanium bolts alone were $800'ish. They are going on Stephen's 997 Turbo. |

I am not doing springs, I am doing the Bilstein PSS Damptronic system for PASM. My set is in and sitting at Bilstein in Los Angeles awaiting engineer approval to be released to me. I was bummed that I didn't have it for this event, but maybe my next event I can try that out... | | | | | 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 just put the graphics (magnetic) on for the Club Race weekend because Fios is a sponsor, they are good up to 140mph at least. Yes, that is a lot of yellow, but I could probably find a few more places for some.

Country: | | Dispatch from K-Man S:
The LSD is tracking extremely well- at least 3 seconds better on his circuit early today. So far he is passing everything in his path including vipers, C6 vettes, and a 996 GT3 that couldn't shake him and had to let him go by. He pulled out of corner so strong that the C6 couldn't catch up all the way down the straight. More to come when he gets home and starts typing...
Whoo-wee. I'm getting all lathered up and can't wait for my AX tomorrow.

Country: | | | K-Man,
My first question is how are the GT3 seats? I am wondering how comfortable they might be for cross country trips?
The BBS look great. In fact, your ride in yellow is one of the most inspiring. I sure like the seats in yellow as well. Now, about those brakes . . .
Why can't you have a 3.8L? It seems as though maybe you should have gone with a F-L GTR and just gotten it all done and over with. But then, it seems that you enjoy making this a project car in evolution.
It sure is some "project car!"
About those wheels made from carbon fibre. Now, those sound like pure indulgence! |
