remove weight, add downforce.

I didn't see it mentioned and I know most of this forums about keeping it cheap BUT the v8 roadsters front subframe is supposedly good for 10 lbs ....right where you'd want to lose it.

You could also look at using aluminum or nylon hardware for all non-critical connections (e.g. - fenders, dash, etc.). There's a couple motorcyle vendors that sell a lot of lightweight metric hardware in alu/Ti. Not really worth the effort IMO.

good call on the wiring, theres a lot of useless stuff that can be trimmed out. its advisable to build your own wiring harness for the entire engine and chassis.
Wha...? This post is two grammar errors away being warned, and only one idiotic statement.

Why the hell and who the hell would someone want to make a new harness? Dozens of people have documented their miata race car build, and do no such thing. Snowboarder is the first and only I know of that's done anything but just use the stock harness and cut out unneeded wires. And I think all he did was cut the harness where it went through the bulkhead and put a connector there.

Seriously, WTF. Myself, Savington, Keith's Targa build, FM's Track Dog build, Bbundy....Who's advising this!?!

I ******* know you can trim down the harness and make it lighter, I've done it. Your original post, if you can read, suggests making a completely new one yourself, not modifying the original, as everyone else does.

In my years I've seen many efforts to lighten a race vehicle, some included whaleing bolts and or rifle drilling some parts. If you don't understand the term whaleing, think of a bolt that fits a bushed bore. It could be an alternater bolt or a PPF, the part of the bolt that does not need to be the bushed size can be reduced. Yes it is alot of work to chuck a bolt in a lathe to remove a few grams, but it does add up.

I don't think anyone on this forum has that kind of money.

We know, and we don't think that's intelligent. It's significantly easier and cheaper to trim the stock harness down.

To be fair, he was getting an exorbitant amount of **** for something which is pretty ******* common outside of this forum.

There's something to be said about the custom harness in my Dad's vette - no looming and everything is tightly bound and zip tied every 4 inches. In 40 seconds you can trace any wire back to the fuse box which is mounted right on the dash.

If you really wanted to minimize wiring weight in any vehicle/product/house the goal is to bundle components which are 'communicating' with each other as close as possible in order to minimize wire length. I have not messed around too much with the harness under the dash, but I assume Mazda made compromises for the sake of packaging and maintenance which results in a harness which is longer than actually needed in a gutted track car.

We're probably taking grams here of course.
