Is A TCM Racing Top Streetable? Full Build Process [Project 2SJ Ep9]

[@coadylewis7739]

As long as my hair dryer doesn't get soaked in its spot behind my seat, it's streetable.

[@TheCarPassionChannel]

Exactly

[@jochem1986]

That's how I look at it as well. I have a pristine scissor collection behind the passenger seat that I want to keep from oxidizing. Wait, wait, are you mocking us?

[@OOICU812]

You're doing it all wrong. You're supposed to have the chick sit in the passenger seat, drop the top and grab some curves. Her hair will be dry before either of you realizes it.

[@TheCarPassionChannel]

Sup guys, there seems to be a bit of missing the main point of this video. It's not meant to say you should difinitively buy this top over an OEM top. It's simply offering another option that many people don't know about, or that many people have questions about. If you were considering this top in the past, now you have a full overview on how to build it and what all of the components look like in detail. I see countless people on parts pages claiming they can't hardtops for sale. This one ships to your front door. I see plenty of people with more track oriented builds that this would be suitable for (These tops are commonly used in Spec Miata). As stated in the video and on TCM's website, this is a racing part that has been adapted for street use. Keep in mind that the Lexan window is significantly thinner than the OEM glass, and also easy to scratch and prone to fading/clouding. Some kind of coating can potentially keep it in better shape. This video is to simply help you determine what option is best for you and your car. Cheers

Greg I agree especially when prices of the OEM hardtop are going through the roof gives other people an avenue to purchase a hard top that’s affordable 😊👍

Greg, miatas are the best for cold climates. They get up to temp extremely quickly and their heaters manage to keep the cabin hot with freezing colds and ripped soft top. Best winterbeater choice ever.

[@awesomecooly123]

It gets too hot in miata, have to turn heater off even if its just blowing on level 1

[@joshuacraven6206]

Agree. Daily drove mine with a hardtop through 3 winters in Ohio and the cabin was never uncomfortable in terms of temperature. In terms of pucker moments, on the other hand...

[@squidikka]

As a Texas miata owner, yeah, I never even turn the heater on during winter. Summers are absolute hell, though.

[@dragonbrownies517]

Mimy 95 was pretty decent with this rash of extreme cold here in Kansas. From -10 to -30 degrees with windchill, the heater took some time to warm up as with all the other vehicles. But once warm, it was really warm. I had to keep switching from cabin air to fresh air because my breath kept freezing to the windows.

If you want to keep the glass from discoloration I would suggest ceramic coating the glass. I have one on my 99 👍👍👍

[@TheBumbleBec]

Did you ceramic coat it before you installed it or afterward?

[@21April853BC]

Since I started watching your channel I have spent $10k on my 04" NB. Most of the money has been spent on the MKturbo kit but I have also upgraded the radiator, fans, and did some cosmetic stuff like installing new seat covers on the nasty old seats. I also have purchased the Hard Dog roll bar, and done the regular maintenance. I drive my NB nearly everyday to work. I love my Miata.

Another tip is heat fiberglass before applying weatherstripping. Heating fiberglass will help adhesion.

[@dil6969]

When I took a road trip to L.A. in my very clean NA, I visited my brother in the downtown area. I was so afraid of the car and/or top getting stolen I had him help me bring the top up to the 7th floor so I could put it in their living room. On top of that I removed the fuel pump relay. Thankfully nobody messed with it. I kind of miss the days when nice NAs weren't worth much and didn't get a lot of attention. I really feel bad for folks that get their tops stolen.

[@willvanhouten8998]

To represent the cold climate Miata owners: I drive my NA with an OEM hardtop in Michigan during the winter, and it's gotten down to single digits for several weeks this winter. The hardtop keeps the heat in fine without any insulation, and you can totally drive a Miata in cold weather, hardtop or soft top, and remain comfortable. I only switched to a hardtop for dryness and aesthetic purposes. Great video Greg, but ya misrepresented the snow Miatas!

[@nbmiata9507]

I recommend washers on the back of the bolts for the plexiglass window. That way it can disperse the tension of the bolts on the fiber glass less on the center to prevent cracking.

[@jasonrobinson1877]

For the seals between the top and the body I would suggest throwing a coat of silicone grease there, good for the rubber and helps keep the water out.

[@lewismatthews1442]

Good suggestion, I've used the Shin-etsu silicone grease on my classic minis and my MX-5 (before the wife destroyed it) and I was amazed, it made so much difference.

I've been debating a TCM top for my NB2 for a while now, glad to see an in depth video on it. I've always wondered how it would affect overall sound and comfort in the cab if you sound deadened the inside of the top with something like Kilmat or Dynamat.

[@BigIsleJ]

[@GrindhouseJho]

I've bought stuff from TCM and spoken to them about the hardtops, from their end the issue becomes warranty and liability. It's even posted on their website that they wont assemble them and when you begin your assembly you assume all liability. From their end I guess they dont wanna deal with someone hassling them or trashing them, if say, the seals got damaged during shipping. Kinda sucks but I get where their coming from too.

THANK YOU SO MUCH I WANTED A REVIEW FOR THIS HARDTOP AND FINALLY SOMEONE DID IT W THE SAME DISTRUBTOR THANK OYU MIATA DAD AHHHH

[@yankymategarage]

Another thing I feel worth mentioning is lexan "glass" that the fiberglass top comes with will not last. It starts accumulating scratches the second you peel the protective film off and if left outdoors will last 3-4 years before you can barely see out of it, it gets a nasty brown haze and needs to be replaced. I have had lexan hatch and side windows and never recommend them for cars stored outside unless it's a race car and you need the weight savings. Regular glass that comes on the OEM top (that makes it heavier btw) will last forever and is impossible to scratch.

[@NoobProjectCar]

Thanks greg for convincing me to buy the treasure coast hardtop 👍

I made custom lexan windows for my fastback and you can buff scratches out with a dual action/random orbital buffer and cutting compound-just keep it moving so you don’t heat up one spot and melt the lexan. Also, I clean mine with ammonia-free glass cleaner like the “all natural” organic vinegar-based stuff or Sprayway brand you can buy at the auto parts store. Microfiber cloth only! Anything else will leave scratches.

I have a racing hard top on my NB I bought it from some random guy and it has solid mounts. I can’t figure out the brand to this day it has a glass window with a defroster. It’s a pain in the ass to take on and off on nice days but I will note the difference in stiffness from the soft top when cornering and going over bumps.

[@mitchellclarke5966]

Top MX5 content on the web :)

[@BigIsleJ]

Thanks for covering this. I was curious how much of a job it was to prep the TCM top with the street kit :)

[@_Yep_Yep_]

Miata hardtop looks CLEAN as hell. I cant come together on it though, as the open top is one of the main party pieces of the car. I thought it was a stiff platform. Does a top add rigidity? I get the benefit of not having your head cut off in a rollover, mind you....but i think if i buy a miata that's what im signing up for. For basic aesthetics, I also understand it looks faster, cleaner. I also dont track cars BUT i have a significant amount of respect for and appreciate the guys that do because it results in more thoughtfulness in car engineering. Im not sure if im weird or normal, but I would take a sporty car and enjoy it driving corners fast and the good performance at regular speeds...just better than a minivan or a mom car, and the looks are more iconic and artful.

[@simonbusby7817]

how does exhaust drone differ between the soft top and the treasure coast top

[@christianzinn7636]

Thanks for another great video! I think I'd go with a white fiberglass to for the red car. Not only would it give contrast, but believe this OG when I say it Will be Much Cooler (temp wise) inside the car and you could prove that with a thermometer (before & after). If you are going to change the trunk why not the hood as well? Isn't it More important to lower the weight in the middle and front of the car, then the rear? I would think the last thing to do for handling is lighten the rear, not the first. Just Sayin' Best Always, Chris Zinn

[@paulkimble4548]

[@tedstriker754]

That top isn't bad. But the inside is rough looking. I'd peel ply that after finding out what kind of resin it was made from. Either polyester, vinyl ester or epoxy. That would give it a smooth finish. Then paint it back on the inside. and I'd look for some of that 1/4" thick sheet black foam with adhesive on one side like the OEM tops have on them. It's too bad they don't have the chrome blocks that go over the Frankenstein bolts. It looks like that's missing on the racing top and needs to be there. The attachment brackets look exactly like the Garage star brackets I got for my OEM top for theft deterrence.

Hey Greg, when installing the one piece window seal what side of the car does the tapered end go? does it wrap around the front of the top like the factory seal?

It was minus 10 degrees C (that is 14 degrees F) in the netherlands last week .

And that's exactly why I made this video, neither is "better", it all comes down to personal preference. Each have their pros and cons, I'd way rather have this top on a track driven car, but an OEM top is more suitable for a Miata in really good condition, or that you want to be nicer for street use.

The price of hardtops in the UK makes up for the higher rate that the mx5s rust at here. I've seen hardtop sell for $1500 when a good one in the uk is about £250-300. One suggestion for the painting, I'd say peeling the middle bit of the protective plastic before the paint has fully dried would be a better idea. Less likely to pull any of the paint up, as the paint will still be soft.
