  1. Loren, I am looking for an '04 GT3 front caliper rebuild kit. I've not looked at the rears yet but if you know the part numbers, I'd love to have them too. I changed front pads this weekend and the outter dust seals fell apart like they were made of burnt paper. I'd like a full rebuild kit with all seals and possibly even new pistons. Thanks in advance, Hank
  2. Tool Pants, Thanks. I see my mistake. It all makes perfect sense now. Hank
  3. threeOh, I think you'll be shocked (no pun intended) at the difference air pressure can make. And, not to be argumentative, but there are several "true" race shops with guys who have been tuning suspensions forever that can make the car do anything you want it to do. The trick is finding one of these guys and then getting them to mess around with a street car. The last element of that recipe is testing. It takes time to dial in an adjustable suspension as in a lot of hours and a lot of new tires! It is very dependent on what the driver wants to feel. The bad news is what feel good one day may not feel so good the next. Hank
  4. I finally got my manuals today. It looks like the stalk connector pin 1 goes to ground, stalk connector pin 2 goes to plug 2 (the white one behind the instrument panel) pin 20, stalk connector pin 3 goes to plug 2 - pin 21, stalk connector pin 3 to plug 2 - pin 22, stalk connector pin 5 to plug 2 - pin 23, stalk connector pin 6 is not used. Can that really be all? The 993 requres 15 other connections to get the functionality to work. Thanks, Hank
  5. So, Tool Pants and others, It sounds and looks like you need the stalk, five wires, one of which goes to any ground, and a BMW harness connector. Once this harness is fabricated you plug one end into the stalk harness connector, one wire to ground and the remaining four get inserted into a connector that is already connected to the back of the display unit. Is that correct? What am I leaving out? Thanks in advance, Hank
  6. threeOh, From your post, it sounds like you have some experience with suspension tuning. Do you find the ride of your 40th harsh on normal roads? Porsches, as you are most likely aware, are very sensitive to tire pressure. I am running 34 psi front and 36 psi rear on my ’99 C2 with 18” wheels and stock sized Pirelli Asimmetricos. This combination takes out all of the harshness and gives the car a nice feel for the road. I understand that your car is much newer than mine and a good bit more powerful but tire pressure is an easy place to start. I have owned several 911s including a GT3-Cup which I raced in Speed World Challenge and I do admit that driving a rear engined car is different than driving a more conventionally configured one, however; I don’t think any of the street versions of the 911 is anywhere near “the limit.” I would exclude cars like the GT-2 and GT-3 only because they may be purchased by people with little driving experience and they offer little in the way of electronic driving aids. Lastly, I would say that you will only get incremental improvement by exchanging your current suspension for another factory suspension. I wasn’t sure by your post if you are talking about street-only driving or if you are using the car at Drivers Education events. From the posts I’ve read the X74 package sounds like a great Factory alternative. If your car is a street car then I would consider the X74 as an upgrade. If your car is a dual purpose car with a lot of track use, then find some adjustable shocks like the Moton Club Sports and a spring rate that you can live with on the street and have a ball. The only downside that I can see is that you have a beautiful car and it is hard to protect the finish once you start tracking it. Hank
  7. Tool Pants: I created a login on the Boxa board and now know how to order the DVD and in fact did order one. Sorry I didn't log in to the other board before posting. Hank
  8. Tool Pants: I read the post you recommended and before I say anything else, let me say that I don't mind buying your DVD as I stated in my second post. Thanks for the shopping list of parts. I am still unclear as to what to do with them but I am sure the DVD explains all of that. I am very new to the 996 world but very experienced with 993s. I did own and race a '99 GT3-Cup for a year, however. So, how much is the DVD and where does one get one? Thanks again, Hank
  9. Tool Pants, What is involved in completing the retrofit so that can see all the additional displays? Thanks in advance, Hank
  10. Tool Pants, I drove the car today and I was wrong. It does display the outside air temperature. The race shop that I use has a PST2. I'll ask them to activate the OBC on Monday or Tuesday. Thanks again, Hank
  11. Tool Pants, Thanks for the reply. I can not see the outside air temperature now. I think I would want to use the factory stalk. Your DVD looks interesting. Where can one purchase it? I just did a retrofit on a 993. It was not difficult but it was involved. Thanks again, Hank
  12. Has anyone done a DIY project of retrofitting OBC functionality in a 996 ('99 in my case)? Hank
  13. Mark, I'm not sure any of what I am about to write is helpful. My car is a '99 6-speed with 64,000 miles and I live in Georgia. It sounds like our weather is similar at the moment. My car runs at a similar temperature to yours. The temp needle usually points at the "0" in the number 180. With just a little stop and go traffic and some fun acceleration the needle approaches the hash mark between 180 and 250. I am guessing that that mark represents 215 degrees? So I suppose that means that my car runs between 190 and 210 regularly. Water is a much better coolant than antifreeze. I don't know what the Porsche fluid is, so perhaps it is something other than ethylene glycol. Plain water would cool the engine better but would have no resistance to freezing no lubricants nor anticorrosion protection. I hope there is something useful in this. Hank
  14. Super D: If I were going to race a 996, I'd ask Chris Cervelli who has been doing it for a few years. Chris owns Technodyne and the web site used to be www.technodyneracing.com I can't seem to get there any longer. Chris is a great driver and has a great reputation as a mechanic too. I think he would be the man to ask. Hank
  15. Chad, I do still have the RS Clone. I have replaced almost every single part of the car. It is really a neat machine. I actually drove it today at a test session at Roebling Road. I think you'd like it. I am enjoying the 996. It is a great car. I want to be careful not to compromise its great streetability by bolting on race parts. I think I want to put a Euro M030 suspension and a GT3 aerokit. I like the center radiator DIY too. Hank
