Since this is the "anything that keeps your 7 on the ground forum", i'd think this should be posted here. Aerodynamics keep your car on the ground...

I like to take fairly long road trips, and I usually cruise at 90-95mph the entire way. My previous car, an 87 Daytona Pacifica, was beautiful at high speeds. I could cruise at 95-100mph for hours on end without getting that "floaty" feeling. However, i've driven plenty of other cars at high speeds, and some feel very unsafe at 80mph, let alone 100mph.

Now it's back to the question- how stable is the FC at these speeds? If not, would a slightly higher spring rate help keep the shiny side up? Thanks.

 

I've had both my 90 GTUs and 93 touring 150 mph plus. How much faster do you want to go? If your suspension is in good condition and you have a decent set of tires with z rating or above, your car is designed from the factory to be stable at speed. You don't need to mess with the spring rate if you are just going to cruise on the interstate. If you have worn struts or if your suspension is worn enough to be sloppy, there is no point to going that fast unless you want to crash and burn.

 

lowering the car also helps with aerodynamics.

 

The rear spoiler helps out more than you might think too.

 

my car rides fine at 95-100mph... when i take girls in my car, they don't even realize that i'm going that fast.... that's what's important, isn't it...?
