Gen 2 Rear Diff Durability

Next time you go for a drive, when you shift, you'll notice just a slight lag before it displays the gear you're in.

On the first gen it calculates based on engine revolutions per mile. There is a table in Romraider where you can adjust it.

Which means it would need to use the ABS sensors, right? Otherwise how is it calculating revolutions per mile?

Wheel speed sensors

Wheel speed sensor, ABS sensor, it's the same thing.

It's more about how many highway miles I plan on driving. I'm used to getting 30+mpg @ 80mph highway in my old mini. It's a mild annoyance but getting 30+ with the current final drive has me capped at 75mph.
EDIT: this car doubles as my daily (though I don't drive daily) so it does go on road trips.

Have you considered more eco friendly tires and possibly lightweight wheels?

There's many ways to find more MPG.

is there an emoji on this forum for jacking off?

He probably thinks the GMA T.50 is garbage and that Gordon Murray doesn't know what he's doing because it uses a 6 speed.

I don’t understand people wanting to do a mod that has no return investment or depreciating on sale of car to worry about a few mpgs less of fuel a year and a couple 100 dollars of cost of fuel consumption added for “more torque per gear acceleration” its counterintuitive. You mod for fun… gas consumption is negligible and shouldn’t be a factor in a sports car.

What’s your threshold a 1.875mpg loss? lol you get what I’m saying

The stock gearing to me is perfect for city and hwy balance. 4.3 would be fun for tight curvy roads and annoying on the highway especially with an exhaust.

And the twisties, or track is the only place it makes sense. In a straight line it's typically slower because of the extra shifts. Figured this out on my R6 years at the drag strip and you can even shift way faster on those than a car.

Going through the traps in 5th was slower than going through the traps in 4th.

I have had plenty of sport bikes as well. Rode dirt bikes since I was 8 (36yrsold now) I’ve retired motorcycling. Last bike was 2012 zx10r sold 2 years ago. Felt the brz would suffice my itch for cornering.

600cc need all the gearing they can get -1f +2r sprocket to start.

Yep, that's exactly the gearing change we made on it. Fun when we got to Southern Missouri and NW Arkansas, most of the time you could just leave it in 4th and go.

To keep ourselves in check on the street, we took the motto that if you had to use the brakes you were riding too fast. IE, banging gears when it's straight to nail the brakes and downshift for the corners.

Just keep it nice and smooth. But I haven't ridden in years since I wrecked at the track and ended up with post-concussion syndrome. It's terrible.

You learn to love something like riding so much sometimes you need to learn to let it go. Between skill, confidence and some probable luck eventually the best of riders will be dealt a hand they have to fold. Hopefully they come out unscathed and not permanently injured or dead. I miss it glad you are ok.

Yeah. I watched one of my good friends get killed. 3 of us also went down in the wreckage, I was the only one not banged up enough to make it home

Seeing a friend dead on the road, really fucks you up.

It's not just MPG. An engine that's spinning at 3500 when highway cruising has more vibration, noise, and wear. It deters high speed cruising. In my STi I'd gradually back off to 70 cuz it just didn't "feel" like it wanted to go 80 for hours. A 4 cylinder will never lope along at 80mph like a Corvette but something closer to 2500rpm is a lot more pleasent when power isn't needed and you're trying to comfortably cover miles. You can always downshift for uphills and passing.

But yes, I do want the lightest 17x7.5 43mm wheels, though might settle for the GR accesory wheels, and when the stock tires wear out I'm going to consider rolling resistance ratings (and weight) on replacements. I suspect low rr tires would be quieter as well.
