Eibach Prokit M3 springs on 325e

[G-man55]

Is anyone running the Prokit springs for an M3 on a 325e/i? I can't determine whether they would drop the car more (made for a *lighter* m3) or drop the car less (the stock springs were already stiff on the M3, these are probably stiffer). Anyone have experience with them?

Eibach ProKit is doodoo butter. The spring rates are the same as/mildly softer than a stock 325i. I don't know what the M3 rate is (actually I'm just too lazy to look) but I'm sure it's not any better. So, all you would really be doing is fucking up the way your car handles by putting those springs on. If you're more interested in the ride height than the way the car handles, look into a set of JOM or Raceland coilovers. The kit comes with shocks, springs, and height adjusters for less than $400 and feels better than Eibachs.

All I took away from that was doodoo butter.

Prokit is not that bad I admit it's no race spring but I would not say they would take away from the cars handling. They are a nice way to get lower without having to go with stiff springs and I think they are a little stiffer then factory sport springs but I don't feel like looking up the rates

The M3 stock springs are anything but stiff.

The "OEM +" upgrade, IMO, would be H&R sports and Koni Yellows. You won't have to worry about your oil pan, it will ride better than a new BMW with run-flat tires, and it will outperform the eibach setup (and probably cheap coilovers, too).
