my car feels twitcy as hell at that speed

my car asplodes after 65

why? is it a crime to wear a helmet in a car?

slamming on the brakes at 110mph for a chicane, then yes, it is a little sketchy at those speeds.

I read somewhere that someone with a v8 swab had a miata up around 180 and it was aerodynamically crap at those speeds. who knows what he had done aero wise though.

Actually, he was only pulled over by the fashion police.:greddy:

oh noes:bowrofl:
BUSTED

An open top miata is aerodynamically crap at any speed, even standing still. Its co-efficient of drag is in the high 0.5's range compared to your average Toyota Camry which comes in at half that value, around 0.27 to 0.28.

With top down, its not that the car is unstable, its just twitchy, with my alignment little movements of the wheel translate into alot at that speed.

On my way to the NJ beach I did about 115 for like 3 seconds. The car friggin grabs EVERY crack in the road, and above 100 is when the front end just seems to get lighter and lighter...

I really would not want to be driving a stock body miata over 130 lol.

mine feels perfectly fine up to 100 at WOT, i usually dont go faster, but the times where i've hit 130 it felt decent. and my alignment is pretty crappy.

It's all about caster and toe at the front wheels.

Still waiting for laws on helmets in street cars...?

Yeah, seems to be against the law in at least every state Arkmage gets pulled over for it.

You are the man.... that's awesome. ;) Multiple times and in different states, makes that legendary status.
As far as helmets being illegal for passenger cars, I don't find any real why nots.
Sure vision is somewhat impaired, but those of us who wear them are already a step ahead with awareness.
Yes, it covers both ears, but todays stereos and quiet cabins are the same effect when it comes to hearing emergency vehicles. Bleh.
I think a full face helmet when combined with an airbag and typical seat belt may pose for some face fractures, but with proper restraints and a helmet - you are way better off.
With a high percentage of head injuries that occur in crashes on public roadways, I wonder why some litigator hasn't persued this further.
From what is written law wise, it seems awful gray (grey) to me.
I'm sure there is definitive info somewhere.....

I've ridden in an Atom on the street, with a helmet...rather than eat bugs.

June bugs at 70mph FTL!

Ditto.

This (not mine) miata was stable the other day. Its completely stock.

i've had mine maxed out at 120+mph and it honestly didn't feel unstable at all.* actually, if anything, it felt MORE stable when it got past 80.i have the front air dam on it though - when i put it on i noticed a difference.* feels like the front of the car gets sucked down with more speed.

As far as the helmet thing goes i drove around with my auto darkening welding helmet on once just to see what peoples reactions would be, It was everything i expected.

a welding helmet? HAHAHAH

I've been over 140 indicated once on an empty freeway and the car was wayyyyy more stable than I though it would be after reading about how unstable people say it is. No airdam, basically stock ride height.
