  1. John Thomas, the Solo2 God, won FP again... Toby coned away the winning run.
  2. West course - Toby's fastest run. Should give you guys an idea how big the new Lincoln site really is. http://www.vimeo.com/6495030
  3. Well... hell... I hope you win too! Now my loyalties are divided. Tell Toby when you see him that you're running my hood and that he doesn't stand a chance in the Svenska Panzer. Another of my customers, Mike Simanyi, is running a M3 in SM.
  4. http://forums.hybridz.org/showthread.php?t=103860
  5. All Data lists how much it pays, not how long it takes. Just finished replacing a turbine revolution sensor on my step daughter's Q45 and Mitchell said 5 hours. I did it in 1/2 hour.
  6. You've already bought the setup. Asking for opinions now seems kind of late to me. Put it on the car and drive it.
  7. Go Toby! Sorry guys, Toby's one of my best customers.
  8. Enduros should be under a different rule set then IT IMHO. Here in Cal Club they have supplemental rules for any of the Enduro events and its far easier to get a rule change there then in the national level IT rule set. Maybe that's where you should make your first effort at a competition adjustment. After a couple years you can use that as backup for your proposed national rule change. New aluminum drums are NLA as has been said here. Used drums are on every S30 and you just need to start harvesting and stacking them on a shelf. Another alternative is having the used drum surfaces built up using a plasma spray. That will also let you add a high Manganese steel which will wear better and provide more friction.
  9. I'm on the same team but that doesn't mean I have to agree with you. :-) I've run IT sprint races and 3 hour enduros and never encountered a cracked rear drum. Lots of cracked front rotors but the rear drums have never really been an issue. I do know other Z racers who have cracked the lining of the drum but they've admitted to turning the drum beyond the minimum stamped on it before the event. Maybe the tracks and driver's here on the west coast are easier on brakes, maybe we run different shoe material, I don't know. You do know that a complete rear drum, shoes, backing plate, springs, wheel cylinder, etc. weighs in at 12lbs. 9.3 oz. right? You're not going to beat that with any disc brake install. And yes I've make a shoe change during a mandatory 10 minute enduro pit stop. Its hot but it can be done by two people if they practice, the drums are modified with two 1" holes to access the adjuster, and the adjuster linkage is modified. Also, having been on a vintage racing comp committee and dealing with Porsche guys crying "SAFETY" whenever they wanted a mod makes me very skeptical of anyone making a safety claim as part of a rules change. So, yes we're on the same team and no I don't think the rule needs to be changed for IT.
  10. As long as you can find used ones that are not at their wear limit, you still have a supply. I've probably got 20 on a shelf here in the shop.
  11. I'm with Jon, what's the safey issue with drums?
  12. JMS in El Monte. They've done a lot of L6 engines over the years and they've build two ITS sepc engines for me. http://jmsracing.com
  13. As opposed to necessary stress? FYI... going to a wider wheel and tire combination put more stress on the wheel bearings then offsetting the wheel and tire combo out 1/2." Lateral Gs and all that.
  14. Whichever of these cars you decide on, please do a very careful check of the title and VIN. Check with the DMV in the state the car is registered to make sure the title is correct. There are a lot of bogus titled "skylines" here in the US (Maxima VINs tend to be used most often).
  15. I think the chrome handle is a tool box door handle on a 280ZX or Z31.
  16. IMHO, TIFWIW, ... The difference in spring rate between stock and Euro springs is insignificant when thinking about ride. Shock compression damping, tire sidewall height, tire construction, and tire air pressure all have much greater affects on ride then spring rate. Springs add "firmness" to ride while the items I listed above add "stiffness" and "harshness."
  17. Very few engines were affected by this and Nissan replaces them on a case-by-case basis. As with all things on the Internet, the significance has been greatly exaggerated.
  18. And more exceptions... Glad I said I think. See what thinking gets you... :-)
  19. I think droop limiting is generally used on the non-driven end of the car. The front on a RWD car and the rear on a FWD car. There are exceptions to as evidenced by a lot of DTM and BTCC cars.
  20. I guess I missed his questions. I keep the rubber outer bushings on the rear LCA for street cars to reduce road noise.
  21. How about a book per car? Imagine the pennies you'll make! :-)
  22. Alan, Maybe there's another book in the making?
  23. What a wonderful car. I've seen Octane Magazine here in the states at Border's Books on the big magazine wall.
