Best Conservative Drop Springs for ZCP

chujk1985 · 05-08-2019, 10:22 PM

What are the best spring options if I'm looking for a conservative drop and are close to stock zcp spring rates?

FriedPiston · 05-08-2019, 10:43 PM

Eibach Pro Kit V1 springs. I have a very lightly used set for sale if you're interested.

Are the spring rates pretty similar to stock? Or will they be a bit "softer"?

Spring rates are quite close to non-ZCP, and just a tick softer than ZCP.

I was running front springs only on ZCP. It was the perfect drop for my needs.

I've been to Vegas a million times, but never been to a single EDC event.

I have heard plenty of stories where kids have fainted due to dehydration, died from from drug/alcohol overdose, and the usual medical issues associated with massive music events.

The positives do outweigh the negatives, and it hasn't stopped a few of my friends and colleagues from attending every year.

I can chime in about edc, I went last year in 2018. Expect long traffic lines to the event give or take 2hours just to get into the venue. Lineup was way better last year, but regardless edc isn't a event to miss out highly recommend going at least once in your life.

What springs are you running now since your selling the Eibachs.

Zero issues. I was on the fence about V1 and V2's, I ended up going with the V2's on my 18 ZCP with 12mm spacers in front, 10 in the rear. It sits so perfect and the ride is softer and more livable than the ZCP Springs.

The Eibach spring rates average 5% stiffer front and rear over F8x base springs and 10% softer in the front, 4% softer in the rear than the ZCP springs.

RevNev · 05-23-2019, 10:19 PM

The "wheel rate" (the bit that matters) was stiffened more in the rear with the ZCP than it is in the front compared to the base M3/M4. The Eibach's maintain a similar front to rear wheel rate ratio as the ZCP but slightly softer.

We tend to think that a stiffer wheel rate means the car potentially handles better but in fact, softer increases tyre grip providing the increased body roll doesn't induce too much positive camber and overload the outside of the tyre. I've found with the M4 ZCP, the slightly softer Eibach's with the lowered ride height is faster than the stock ZCP setup particularly on bumpy corners and in efficiency mode, the car is slightly more comfortable.

The ratio change stiffening the wheel rate more in the rear increases oversteer or reduces understeer and Eibach's maintaining the ZCP ratio provides the same handling balance with potentially better tyre grip. I don't know what the handling balance is like with the V2's rear ride height lower than the V1's but a lower rear ride height induces understeer that the V1's reduce.

IMHO the V2's make the car look like it's still too high in the front like they are stock and the V1's provide the best stance aesthetically and reduce understeer without the need to add too much negative camber in the front. The V2's are a USA thing that isn't used by Eibach globally and I don't see why USA found a necessity for V2 with the same car distributed worldwide

This is V1 with CS wheels and 10mm spacers
