don't mind me, I'm just out hunting.

How bad of an idea would it be to run Star Specs through the winter? I'm in Central Texas, so you can probably count the number of days where it'll be below freezing on two hands, but it'll probably get down to the 50s for good stretches.

I've got a track day Dec 9th, my car currently needs an alignment and has lovely Chinese tires on it. In an ideal world I'd just get new tires/wheels and swap on bad days, but I don't want to shell out the $1300 for a new set of 6ULs along with Star Specs to fit it. I am considering just getting a set of them now for my stock 14" wheels, and then when those need replacing I'll get the new wheels/tires, but I see people saying that the Star Specs are like skating under 40.

I just want to avoid doing a track day on lovely tires, seems like a waste.

Is it your only car or something? If not, just get star specs. As for having good/bad rubber on track, you're in a miata. It's not like it's going to be particularly fast either way. But if it's your first track day (?) I'd almost say don't get good rubber in case you flat spot them or something. No idea what your experience level is though.

It's my daily driver, it'll be my first track day. As I said eventually I will want to get a separate set of wheels/tires for the track, although now I'm wondering if it's just better to run this track day on lovely tires, and save up so I can have the new wheels/tires by the time I do another. That's probably for the best anyways.

That's because yours are off a 93le and 14".

95M wheels are 15" and are more desirable for some reason. I know they are super light, but can't be any lighter than the 14".

If you were on the east coast I'd snag those off you in a heartbeat.

They really aren't that bad. The hole are just the right size for a finger. The HP+s make it a pain though. Cleaned them 4 days ago and they really need it again. I can't wait to move to nice clean quiet pads (probably mazda pads) and then just run race pads on track days.

Hasn't been buffed or anything yet but from his facebook

"On this car I gave it a thorough washing using Dawn dish soap to strip the old wax off, followed by clay-bar, then began polishing. I finished it off with Griot's Best Of Show wax."

The real test will be what it looks like in a few weeks. My old E30 got the same treatment and looked great until it got wet then it went back to faded and ugly. This will get likely get paint at some point so he is going to experiment with a few techniques on it when he has time.

I have a problem that hopefully someone here can help me out with!

Background: In July 2010 I bought a 1996 Miata non-runner. The kid suspected it had spun a rod bearing. Pulled the engine, disassembled, confirmed that a rod bearing was spun. Had a knowledgeable friend look over the engine to see if anything else was obviously wrong. He didn't see anything, so we replaced the bearings and rebuilt it. Got it back together, spun a bearing again. Sold it as a project to a friend. Pulled engine, disassembled, had some pros look. Turns out that the crankshaft was bent. Got a new one. Put engine back together. Runs like a champ...

... except that it burns oil, very noticeably after engine braking. My friend did some research and from the symptoms he was experiencing, it sounded like the valves were the problem. New valves were about the cost of a rebuilt head, so he just bought a rebuilt head. We pulled the old head, put the new on. Fixed a few things while we were in there, but we're having the same symptoms. Read earlier this week that the PCV valve was another frequent culprit. They're cheap, so picked one up at the Mazda dealer. Got it installed today after work. Same symptoms.

Symptom specifics: I have a place near me where I can coast for over a mile. When I coast the car in neutral for the mile, then shift into fifth and accelerate out, there's no noticeable smoke cloud behind me. If I roll down the hill in gear, then step on the gas at the end to accelerate out, huge smoke cloud. Folks behind me confirm that it smells like burning oil, and it's blue-ish.

I tend not to engine brake much when I drive, but he engine brakes a lot and he's had it burn over a quart of oil on a fifty mile drive. This strikes me as excessive.

Suggestions? Sadly, I have no idea whether it burned oil before I bought it, so I have no idea whether we introduced this problem or not. I thought we'd been over the block pretty well and that work was supervised by someone that knows what he's doing, but I'm running out of ideas after putting in the professionally rebuilt & tested head.

Do a compression test or leakdown if you can. Oil can only really get into the cylinders from 2 or 3 places. PVC (intake), valves, rings. You've checked 2 of the 3.

Yeah, vacuum can pull oil up past the rings too.

What is the oil consumption overall like? It could still be the valves. Just you wouldn't notice while normal driving since it gets burned off with the fuel.In gear down a hill means there's no spark to burn it all away, so it collects.

That's my theory anyway.

It doesn't seem too bad, but I will need to test more. Yesterday I checked the oil level, drove the car to work (forty miles), and then checked the oil level before I set off for home. It was essentially unchanged (maybe a tiny bit lower?). That's only forty miles of "data", but on his commute (fifty miles), he'd get the car to work and the dipstick would be bone dry. We're thinking that's the difference in driving style (minimal engine braking vs lots of engine braking).

Obviously a better answer would be "it burns this amount over the course of a thousand miles". I don't really want to put a thousand miles on it (my feet are too big and often get stuck going from the dead pedal to the clutch), but I'll drive it a while more and see if I can't get a better answer for you.

I need to go through the brakes on the Miata. Plan on new rotors, pads, lines fluid and lugs. I'm already replacing one caliper and trying to decide if I should just replace the other three while I'm in there or just rebuild them.

I get a pretty good discount at O'reilly and I need to see what they charge.

Or just had the whole motor rebuilt by a pro, because who knows what else is wrong when you fix one problem of a non running engine, other poo poo tends to crop up. But yeah just replacing the motor is usually the easier and cheaper solution when you're dealing with opening up the bottom end.

I don't understand the lugs... But if your calipers are working, who cares? You should only replace or rebuild a caliper if it has seized. If you want to be thorough, replace the front hubs and the rear bearings. (maybe go ARP studs)

Track wheels are wider than stock so while they fit I'd feel better with a little more thread showing, also one is missing and one has hosed threads.

Once I sell off a bike or two and start putting this thing together would there be any interest in a project thread of slowly turning a stock Miata into a spec racer? Between that and the other stupid poo poo I do it might be entertaining.

I don't envisage driving with the top up all that much, and as far as I know I don't have any rain rail issues. Not sure how to tell without taking the old one off. According to miata.net, even if the rail is bad there are Home Depot-style fixes that work well.

What's the best way to replace the head unit & speakers on a '99 unlucky enough to have a Bose? I know that there's some crossovers in the doors and an amplifier in the dash that will need to go. Is it a gigantic pain to replace the Bose system with something else and I should just let a car audio installer do it? I'm not opposed to the work, but if I have to disassemble the whole dash I'd consider letting someone else do it.

saint gerald
Apr 17, 2003
So here's the next problem.



The way I see it, I have a few choices.

-- Get a bra to cover it up.

-- There's apparently a rattlecan GM color that's a close match for Miata red. I could pull the bumper cover, give it a couple of coats of that, a clearcoat or three, and bosh. Possibly.

-- Pull the bumper, take it to Maaco, and pay a few hundred (?) to have it "professionally' done.

-- I do have a medium-size compressor and a spray gun. Automotive paint seems to be very expensive, though, and I'm not confident in my spraying abilities. Maybe I could do better than a rattlecan job. Maybe not.

What's the best cost-vs-results compromise? At the moment, I'm thinking rattlecans, and with the option of sticking a bra on it if I somehow manage to make it worse. I don't expect showroom results -- after all, I bought this because it drives well, not because it's pretty. All the same, I think there's scope for cheap improvement here.

I would assume the technical mounting aspects of it can go will vary based on your specific rollbar geometry. From a viewer standpoint, try to get it somewhere where we can see the instruments and/or shifter with the wide angle. In my experience filming from inside cars, a view from behind the driver looking out the windshield doesn't really do a good job of capturing what's actually going on.
