Have you driven a square-tired S2000 with a higher rear suspension frequency? For reference, I am on 16k/15k springs and square tires. This is also a 50/50 weight distribution car that we're talking about. A track car at the limit is a much different beast than OEM tuning.

 

Nothing that high, nope. But like I said I agree that the Hz stagger is not worth any thought when you are focused on performance and not comfort. At higher spring rates the rule is thrown away. At lower spring rates, it seems fine. Ex: a stock s2000 is a good factory track car and it follows the Hz rule.

What's your setup to require that spring? hoosiers and/or aero?

 

Yea, it's a NASA TT5 car. Currently have it setup for RC1s to be able to run lower weight, but suspension was valved for Hoosiers.

Don't get me wrong, a professional driver will be faster with the setup you're talking about, but for us it is very dangerous and hard to drive. I've done testing to support this, I'm just not allowed to post details unfortunately.

 

There is a reason that virtually everyone in the STR setup thread has higher suspension frequency in the front than the rear on this car. Lots of people set up autcross and track day cars this exact way. Specifically on the S2k, people tend to run more up front to help with oversteer and to keep a higher transitional response up front. That last point is even more important on an autox car but is important overall of course.

 

i've run 800/800 for str autocross but it only works in certain situations like on concrete, but i wouldnt be comfortable using this for track duty. you have to be really on top of the car all the time with the square spring and a lot more precise on the wheel and pedals. there isn't much room for error and have to be comfortable driving the car with a lot of oversteer.
my track setup is 700/650 with more front bar and less rear for a lot more compliance and safety margin.
