  1. Yeah, I noticed that as well. But it does offer the ability to export the data in a couple different format to allow analysis using other software tools. https://www.racebox.pro/info/session-export Personally, I’ve been using Harry’s and TrackAddict; but am looking to incorporate more sophisticated data logging/analysis capabilities this year. Clark gave me a great deal on a DL1, and I’ve only just begun to scratch the surface with it. Always on the lookout for new and interesting capabilities, and this one caught my eye. r/John
  2. On the topic of data logging tools, has anyone had any first- or second-hand experience with the Racebox Pro? (I didn't know this, but it's produced in Bulgaria.) Seems to have a lot of organic features not inherent in many other data devices. The biggest weak point I've come across is the app apparently, but the company seems to be improving it and releasing new updates regularly. Overall, looks like a lot of capability for the money ($279 on Amazon). https://www.racebox.pro/
  3. Yes, many of the cheaper ones work fine…as long as they fit tightly on the splines. I’ve used a couple of them (like the “Boss”) without any issues. If you’re considering a removable or tilt hub adapter, I would not go cheap. The cheap ones don’t lock securely, they don’t last, and can rattle loosely. I’ve been using an NRG removable hub the last two years and really like it.
  4. Hmmmm....I don't think they'd be different. I've used several of the same steering wheels on different years without any issues. It's possible that our measurements differ by 1 mm because I was measuring the ID of the steering wheel mounting hole vs you measuring the OD of the steering shaft....and they're both splined, which can result in small differences in measures. There are many hub adapters available to fit the Z; just make sure you get one that has the correct bolt pattern to match whatever aftermarket steering wheel you choose. Something like this one offers two different bolt patterns for wider compatibility: https://www.ebay.com/itm/262525631164?chn=ps&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&mkscid=101&itemid=262525631164&targetid=1645685073808&device=c&mktype=&googleloc=9008565&poi=&campaignid=16730423415&mkgroupid=135815925780&rlsatarget=pla-1645685073808&abcId=9300841&merchantid=101732007&gclid=Cj0KCQiAw8OeBhCeARIsAGxWtUxpzV5oqsS3RU9JHDRjsUVCegH8PwffL3jdbZA6SpbYsds4fwLuodwaAtV7EALw_wcB If you've been wanting a removable (or tip) steering wheel, now's a good time to do it! NRG makes some nice, quality hub adapters for that kind of thing.
  5. Here ya’ go: Diameter, 14 7/8” Depth, 4 3/4” Thickness, 24 mm Steering shaft dia, 16.5 mm Steering shaft splines, 36 Took these measurements off a metal, three-spoke wheel…from a 1973 260 IIRC.
  6. @fusion, do you need measurements from a stock steering wheel? I think I have one lying around and can measure it for you, if you like. LMK. As Jon pointed out....steering wheel positioning (and steering effort) is a highly personal thing. And it's relational to several other factors, like driver's physical attributes, seating position, and the car's intended application. What feels right to one person can be horrible for another.
  7. I can second that! I’ve had a couple sets of 13” wheels and really liked them for auto-x. In addition to the weight advantage, the smaller wheels can lower the CG without compromising suspension geometry.
  8. Yep, that was it. Thx much, @tube80z, @NewZed!
  9. Good points all. The unavailability of Site Admins the last couple years seems to have negatively affected the forum in a variety of ways. Several folks have volunteered to step in/help out in an Admin capacity...no idea if any were accepted.
  10. I would say so, with the addition of the right pads and fluid (as you are already planning). Many of the 370s I see at the track are running stock brakes; but most have switched out to a better pad (e.g. Porterfield, Carbotech, etc) and a good high-temp synthetic fluid. Keep in the mind that the 370Z weighs close to 1000 lbs more than your 240. I ran the stock brakes on my car for track days a couple of years before upgrading....when upgraded with better pads/shoes/lines/fluid, the stock system is quite capable & well-balanced. So you should be in good shape with your upgrades, assuming they've been implemented correctly.
  11. @jessejames, curious if you got it solved; and if so, what was the solution? Do you have any pictures, diagrams, etc of the final installation? Thx.
  12. Are we in a similar situation here as last year? My web browser has been telling me that the site's certificate has expired. Do we need some more donations to cover whatever expenses are necessary? Is anyone else having this "Unsecure Connection" warning message, or am I the only one? Dan, Cary, Jon...anyone? @SuperDan, @tube80z, @JMortensen
  13. @Ont240, look at these pictures of the GC coilover kits...note that the mounting hardware is pictured in these photos. https://groundcontrolstore.com/collections/s30/products/1970-1978-datsun-240-260-280-z-complete-coilover-kit-with-no-cut-camber-plates
