but damn near everyone knows that initial D is part of the 86 heritage

maybe for those that were into the car, but for anyone that liked trucks, that truck was all that mattered. my interest in the delorean peaked at the point that it looked fast, but had a v6 for a drivetrain.


but why/where did people learn of the 86 heritage?

i never knew of intial d or wangan midnight until well after i had decided to purchase the car and started looking into it further. at that point, manga's/anime were the same thing, and were only for the cheeto-covered comic book lurkers.

but without even searching, i can tell you about marty mcfly's obsession was with a 1985 black sr5 xtracab that was a single year option with the old-style solid front axle, but the new style body. that set of roll bars has sent me down rabbit holes that i'm almost too ashamed to even admit to...

toyota even did a promo 2016 tacoma re-make. it was a 1-off-wonder though. they never sold parts for it, and most was custom-fabbed

i've tried finding a source for the light bar-- it doesn't exist anywhere, i've got ideas to build my own. it's the only reason i've priced out hydraulic tubing benders.

Basically all cars need a fluid with a higher boiling point for track days and better pads. This has been well known for decades.

So that's not any deficiency of the stock brakes.

I'd bet the "Performance Pack" cars with Brembo's are using the exact same fluid as the non-Brembo cars.

Just fine on a track with a pad/fluid swap.

Precisely my thoughts - it always confuses me how people jump straight over modifying any other part of the braking system and right to blowing money on a BBK just because they don’t like the feel of the stock brake pads.
And I say this as somebody who blew money on a BBK. And then put akebono ceramics on them just like the stock pads lol.

It's like a lot of modifications.

"I want to do X"
"Ok, why do you want to do X? What behavior are you trying to correct?"

*crickets*

Hell, I want to do a BBK just because it would look awesome behind my wheels and I have no intention of tracking mine.

Want my wheels more horizontal to the local grav gradient and make the car hover.

Simples, right?

The Brembos are red. That's about it.

The stock brakes will engage the ABS, which means they're more than capable of applying the maximum braking force the tires can grip under. If you want to stop better/faster, you need grippier tires, not bigger brakes.

As others have said, the conditions matter more than anything else - on a track you're going to heat your brakes to the point where you start to boil the stock brake fluid. THAT is going to immediately tank your braking ability just like if you didn't bleed the lines and left air in there. So that's why "better" brake fluid is basically required for track days (it has a higher boiling point at the cost of being more hydroscopic, meaning it'll yank water out of the air faster and go bad sooner. It's also more expensive.) Pads for the same overall reason - stock pads are built for road use: low noise, low dust. But at high temps they wear faster to the point that on a track you'll burn them up super fast - like the first day probably.

I mean, the Brembos do look cool with the white lettering on the red, but there is a LOT you can do to make the brakes "better" for a tenth the cost, then get some high-temp red paint and make the stock calipers pretty.

According to this article, the brake upgrade is more than the calipers... larger rotors and pads are part of it too. As the linked article states: not a huge difference in bite... and a fluid change is recommended. I imagine the larger rotors, coupled with good fluid and pads will make this a nice upgrade for the occasional HPDE user.

I've never had any issues running off-the-shelf parts store DOT4 or DOT5.1. In fact the few times I've wound up using "special" racing brake fluid it has disappointed me, just doesn't last as long. IMO more expensive and harder to get specialized brake fluid is not required for most of us.

That's what I'm talking about. Higher DOT ratings have higher boiling points and are more hydroscopic. DOT3 is "standard" because it has the Goldilocks zone of longevity and reasonable heat tolerance.

It's just not tough enough for track use.

I don't even bother trying to explain anymore that tires stop cars.

The article said the pad surface increases (no joke it's a larger caliper and rotor) but doesn't say anything about compound, it's still going to be a street compound. For what the performance pack costs, assuming if you're actually tracking and not just hard parking, you're going to be changing the suspension anyway.

Then I'll the AP Sprint kit which is a better setup for tracking than the OEM Brembo setup..........and it knocks 20lbs off the nose of the car.

Add-in what I'm sure are going to be ridiculous markups. Dealers will be trying to sell these well north of $40k.

For $1200, the 1st gen PP had larger brakes, better dampers and wider wheels. While someone could go through the trouble of trying to sell their stock components after buying aftermarket components, at $1200, this was a good factory package for the price. Even if someone planned to upgrade all of these components to better brakes, coilovers and custom wheels, it was far easier to sell these upgraded components on the used market to zenki owners than trying to sell base components, so it made financial sense to buy these components either way, if not for performance, for resale value too.

An $1195 option available only for the $28,465 Limited trim with the six-speed manual transmission, the Performance package effectively results in a car costing $3345 more than the base BRZ Premium. And forget about it if you eschew clutch pedals. The hardware includes larger 12.8-inch front and 12.4-inch rear brake rotors (up from 11.6 and 11.4) clamped by Brembo four-piston front and dual-piston rear calipers, along with Sachs dampers and 17-inch wheels that are 7.5 inches wide rather than the standard 7.0 inches (1).

I guess I'll just keep hard parking!

Just upgraded tires, fluids, pads, and -2 degrees are all I want/need/use.
