Would your car benefit from less grip in the front? If so, yes. If not, no.

What happens, the front becomes too stiff?

Stiffer springs or sways = Less grip, 100% of the time. That’s why if you want more understeer you go with a stiffer front sway or springs, or softer rear springs or sway. Decreases front grip or increase rear grip.

Yes, only stiffen when you have the better track rubber to have enough lateral traction to load up the outside past the usable travel of the suspension and/or cannot keep a good force distribution on the footprint.
Simply stiffening up the suspension will prevent loading of the outside, and will cause the tire to slip more. Higher spring rates = earlier loss of traction. If you want to reduce understeer, add a stiffer rear bar (opposite of Obioban's scenario) |

For example, stiffer front springs or sway bars will reduce understeer if a current setup allows too much weight transfer and overloads the tire thus reducing grip. Also, in cars that run a Macpherson strut (like this platform), increasing front roll stiffness reduces dynamic camber change under load - therefore increasing front grip and reducing understeer (to a certain point). It also depends on what tires you are using. A stickier tire will require stiffer spring rates to maximize the added grip. Last edited by tsk94; 07-02-2020 at 04:25 PM.. |

Have you driven the setup already? If so what were your thoughts? Do you know the spring rates of your R&T - are they standard? I would be tempted to add the front sway bar as your spring rates up front are likely not that stiff. You may benefit from the stiffer sway bar up front reducing camber loss while corner, but it's a fine line. |

Spring rates are 340/685 I think. The front is definitely firmer than the ZCP suspension. I've done three track days on this setup so far and it's definitely better. There was so much body roll before. I have -3 degrees of front camber but the outside edges are still wearing out first. |

I'm with tsk94. If I had dollar for everytime someone said stiff = less grip. We'd be running around on OE spring rates then to support the car and that's about it I guess then, right? No.
Having got back into sim racing again, balance between axle response has become more critical for me, backed up via motec logging etc. I used to ignore / neglect it and only look at the "magic number" or ride frequency ratios.

How would these compare to running race springs on edc suspension. Will the low spring rates effect bodyroll? Looking for a good coilover to pair with gc camber plates and h&r front swaybar.

FYI I have the edc version. You have to take off the nut from the Monroe mount and use the Ohlin nut or bore it out a bit like what gmx did
