Pretty sure Len only runs something like 6-7k spring in back (coil-over). I think anything under 750-800lb spring up front is going too soft.

Len runs 13k front 6k rear as a true coilover.

len who?

Novak.

Don't add aero to cover up something else. You will be quicker with proper spring rates...and no "aero" than a bd choice in spring rates and a large rear wing.
Larger front bar :)

its not band aiding the rates with aero, its in prep for the aero. what good is the rear onces its on the bump stops in high speed cause the rates were too soft for the downforce

Hey dwnshift, can you explain the huge front bar a bit further. I am pretty new to suspensions been chatting with clint a bit and doing my reading. But based on what I sorta kinda know, not totally clear on why you recommend a ton of front bar. Keep in mind I am still 98% stock. Would it be good for me to go super stiff up front? I am thinking of doing sways before dampers and coilovers just to get rid of some of the body roll. In the meantime I am just trying to learn more about suspensions.

If your on the bump stops ...then your rear ride height is too low.
Its a complete package and everything has to work together.

I think he likes the massive bar because the front end of these cars are so heavy, he likes to prevent too much weight transfer to the outside wheel, thus reducing grip.

Big front bar also helps to load the outside rear tire on corner exit as well. My guess is that transfer to the tire is of huge importance on a small 275 rear section width. I also run a large front bar and no rear bar for the same reason. At Road America you don't set fast lap times with speed into the corner, but how quickly you get out of them. Getting on the throttle early onto the long straights is hugely important.

Exactly. :tup: :tiphat:

That makes sense, I am mainly just reciting what I have read, but I am looking into sways bars sometime soon. "By the book" one would be lead to believe that a stiffer rear sway and a softer front would be what our car needs, but everything is relative to the existing setup of the car. So for a car that is OEM suspension like mine, would you go as stiff as possible up front and then add a little in the back as well?

You'll know why stiff rear bar isn't great, I ran the stiffest rear setting on my hotchkis bar (350 not 370z) and in corners it felt like my rear wheel wanted to lift, so I would start throttling out and my car would kick out.

Some stuff came in today!
