Power steering boiled
Wooooooowwww. I thought it took off quick, but my God that thing can STOP! Looked like you were trying to reverse the rotation of the earth
Always fun to watch you work, but damn it's nice to see that thing beating up some tires, great work man, I hope you keep this one a while
450 rear springs sounds way too stiff from my past experience.

Thanks......
I had nowhere to start (even though I inquired with people about rear spring rates and got no info back). I know that 250 is too soft, and 500 is likely too stiff.
The little seat time I have so far in the car it did well, not bouncy, didnt lose traction on corners, wasnt lifting a rear tire, was able to get the car to rotate pretty easy, very neutral.
I am sure I will change them down the road once I have a little more seat time.
I know Sean's rear springs are still aft of the axle, but are they perhaps a bit further forward than stock? Kinda looks that way from the photos. If so that would reduce the distance to the <strike>LCA front pivot point</strike> edit: instant center and reduce the effective wheel rate, so it would be softer vs. a 450 lb/in spring in the stock location.
^^ I was thinking the same thing - a little shorter motion ratio = stiffer spring for the same wheel rate.
I'd add - if you're serious, Sean, about even more tire (and possible more wheel to support it) -- those will weigh more and that will impact things. So I'd consider getting the wheel/tire package you ultimately want before you start fine tuning the set up. As for camber - seems like for me in a variety of McPher strut cars over the decades, I was always looking for ways to get even more negative camber up front than I had....
This thread is full of so much awesome information. I never would have known about the effects of spring location on spring rates. Considering I want to shamelessly rip off your setup, this is good to know
If the rear spring location is somewhat close to stock, the wheel rate is 1.5x the spring rate.
So a 450lb/in spring comes out to 675lb/in at the wheel.
