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/

Good catch, @NewZed !

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.

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.

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.

@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.

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.

Yep, that was it. Thx much, @tube80z, @NewZed!

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.

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.

@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.

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

@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

I’ve used the biscuit-style camber plates by DP Racing and the bolt-in plates by Ground Control. Have nothing but good comments on both; and both companies offer excellent customer service/support. The DP plates offer the added benefit of allowing a slight increase in caster when used in the front.

How much are you looking to shorten the control arms by, Jon? Even though flipping your existing camber plates didn't yield enough camber change, would switching to a different camber plate (and/or camber plate mounting inside the strut tower) be an option? That might be cheaper/easier than redesigning the control arms? Looking at your pictures from Nov 8, 2012...it doesn't appear that reverting back to OEM LCAs is a reasonable option, is it? As another option for consideration, what about altering the inner mounting points for the LCA? (i.e. relocating them further inboard?)

Nice! Thanks for sharing, and welcome to the Forum! Hope you find any/all info you might be seeking; and please don't hesitate to share your knowledge and lessons-learned, as well. What spring rates are you currently running? You'll find that some folks prefer stiffer coil springs and lighter sway bars, and others vice versa. Additionally, a lot of S30 drivers prefer a smaller rear bar (or even no rear bar at all) for better power-down behavior during corner exit.....don't know how that translates to an S130, but maybe something to consider if you plan to do a lot of auto-x. Cheers!

Wow...looks great! I always enjoy reading other folks’ build descriptions and lessons-learned along the way. Thx for sharing!!

Yes, many thanks to those that have joined and continued this discussion. @Ben280, as you probably figured out...my original intent for that early post was mostly to get the discussion going and illustrate how much useful data can be gathered with simple inexpensive hand tools. Thanks very much for continuing the thread and bringing more sophisticated computerized tools into the discussion. Very interested to hear your thoughts on iphone vs Android organic capabilities. As someone who was dragged into the smartphone world kicking and screaming, I personally am very ignorant on the inherent pros/cons of the current fleet of modern smartphones. I 100% agree with you that the organic location-finding capabilities of many (most?) cell phones is lacking; but that can be overcome by pairing a precision GPSR with your smartphone...true? I've been using a Dual precision receiver for the last couple years with my iPhone, and have found my lap and sector times to be quite accurate (comparing the results in phone app vs light-beam timers). FWIW, Track Addict Pro and Harry's Lap Timer have been working well for me personally....but there's a BUNCH of apps out there to choose from. Fully realize that I need to bite the bullet and buy some more sophisticated data logging equipment; so I appreciate your thoughts on which systems you've had good success with. Thanks! @clarkspeed, many thanks for helping guide this talk. I'd like to chat with you regarding that DL1 unit for sale. Will PM you separately.

Probably a long shot, but I’m looking for a left (driver side) S30 headlight bucket (aka “sugar scoop”). Only need the left side, but willing to buy the pair if you don’t want to sell a single bucket. I prefer metal, but will consider FG if the price is right. Thank you. r/JHM UPDATE: Found what I needed. Ad can be deleted. Thanks to all that replied.

I’ve been using an Eastwood circular saw for 4 years now. Works great on straight cuts, but not so much on complex curves. Makes less mess and generates less heat than a cutting wheel. All of my cutting has been 3/16” or thinner; but I’ve seen people using it on much thicker stuff. Like many vendors, Eastwood offers a nice discount coupon if you sign up for their email list. https://www.eastwood.com/eastwood-mini-metal-saw.html?gclid=Cj0KCQjw1bqZBhDXARIsANTjCPKME5E2ef-O0n5ybLzZk-V9M7iizRAlqnRQRLecq_L4pqfL4htpwSUaAhJ9EALw_wcB&wcid=18406149356&wickedid=&wickedsource=google&wv=4

Hey Amar, thx for the heads-up. We’ve seen similar scams and phishing here, too (unfortunately). Try to report them to the Admins when you see them. Cheers, buddy!

Which LSD is it? STi diffs came with a couple different kinds. And just FYI...it’s completely normal for them to have a fair amount of play, even when “new’ish”. I’ve had that same setup for several years with my nicely built SBC (mine’s a helical center section.)
