  1. Sound and solid advice as usual from @mhr650 also love when you share some of your design works and ideas.
  2. edit 5/3: Steering wheel and DAB are sold. Stock hubs and HP Plus brake pads still available.
  3. Mazda contingency. only available to Mazda engined Mazda vehicles.
  4. Congratulations Roy @LuckyKid and team. Great article, and exposure for ChampCar with Mazda's recognition. Thanks also to @Bill Strong for all your behind the scenes work.
  5. Worth repeating ^^^ West coast means Calgary is right next door to Willow Springs - just like guys from New England area frequent the Sebring and Daytona races. Got it.
  6. It’s difficult to see in this drawing from the BCCR, but the two lower bars circled are the 2 foot well intrusion bars allowed. (They run fore/aft, the drawing makes them look lateral..) The upper bar to the strut tower is also circled. That one can go through the firewall.
  7. Great example of bowed nascar bars doing their job. Hope the driver was ok in that crash. I’ve seen @TiredBirds post this pic before. I’ve worked at an oem doing vehicle crash testing for the past 20+ years. There is no substitute for, or equivalent to “crush space.”
  8. Here’s an example of what @XelderX described Edit note: this one took some thought and planning to weld the door bars up. To get to the welds on the outside of the sill bar, everything was fitted and tacked together, then I removed the 2 lower bars to weld them up fully, then reinstall. Snaking them through the B-pillar, 1 on each side was tricky. But it was cool once finished! (And more importantly, strong and safe. )
  9. WHAT DOES THAT WRAP DO BESIDES RETAIN HEAT IN THOSE THIN PIPES, CAUSING THEM TO FAIL SOONER? sorry bout the caps.
  10. @gundy I know, thanks for putting this together. My number police comment was directed ay my good pal @enginerd in return for his ribbing...
  11. Hey at least you had us on the list. If you guys are the number police, how many races do I gotta do to hold 393 @enginerd
  12. #393 - Stay Focus'd - Black 2003 Focus SVT
  13. I was just looking at the entry list for Autobahn and wondered who 'waiting for data' in car 515 is. Great job Glen, nice consistent races. Also looking forward to seeing you at Autobahn.
  14. Pat of the confusion here is that - Correct me if I'm wrong - there is nothing in the BCCR that allows for +2 gallons on a car with a stock fuel tank. Right or wrong can be debated (and has been, and will be) but the only area the +2 gallon allowance is mentioned is when installing a fuel cell. Also - fuel cell stated capacity does not include the surge tank, fill tube, etc.
  15. Does this come with displacement balls? - with or without holes?
  16. Show me a factory service manual that sets a limit on how much a cylinder head can be decked. SMH
  17. @wvumtnbkr say whut? An RX-8 3400 (or 3500) in the works?
  18. @Black Magic With the Neons being 5x100, it may be better to do as @mender did, moving to the more common 5x114.3 (4.5") pattern if wheels are more readily available in that pattern. (I've never looked.) I didn't take the time to sketch it out just , but I recall when the shops were building hubs for us, they said going from a 4 bolt to a 5 bolt pattern in a similar spacing (100, 114, 4.5", 5" , etc.) is sometimes not possible, and vice versa - due to holes overlapping. There ARE ways around that though (plugging holes in hubs, or using larger diameter knurled section studs, etc.) Once again, I've found that most hub faces and rotors have material to work with in changing a bolt pattern, whereas changing a pattern on a wheel, or getting someone to make blanks, was a more difficult and thus far unsuccessful path (for me).
  19. Thanks @MMiskoe. I just switched from Blues to Porterfield R-4's (haven't tried them yet), under the advice of longtime series sponsor Mark Link at Frozen Rotors. Mark told me exactly what you described - a bit less initial bite, but better modulation. Your experience and observations on slicks vs 200TW makes sense (to me) too. I saw this note on the site @ETR linked: "Hawk recommends if another brand of carbon pad has been used on rotors previously, before using any Hawk compound pads, resurface or replace the rotors." This seems to make sense to me. But it does conflict with something Mark just told me during our conversations. I asked if I'd need new, or to resurface my rotors for the R-4's after using Blues on them. His "trick of the trade" he shared was to save any old Blues you have. Supposedly if you put them on a used rotor and brake a few times as if under normal driving conditions, they will clean up the rotor surface, preparing it for a fresh set of different compound pads. I've never tried it - any old wily veterans that have heard of, or done this?
  20. The problem I found with trying to find wheels that I could re-drill was that most often there are void areas between the lugs for weight savings, etc. Rarely do you have a flat round hub face on a wheel to be able to re-drill it. At least that's what I found... A lot of the Focus guys have gone from the 4x108 bolt pattern to the more commonly used 4x100, by re-drilling the hubs and rotors. There are are multitude of wheels available in the 4x100 size due to their use on Miatas, Hondas, and E30's. That seems to be the size that the new lightweight flow form wheels seem most abundant in, too. My advice would be if possible, redrill huibs and rotors to get to a more commony used bolt pattern. These size wheels 4x100, also seem to be some of the best offerings for the money considering choices, availability, weight and quality. A typical alloy 15x9 or 15x10 is about 16-18 lbs, whereas the flow form versions in those sizes are 10-12 lbs. Close to 24 lbs of unsprung, rotational weight right there! (Oops, shhhhh, nobody saw that....)
