AC Schnitzer Springs

Perfect drop IMO. I just took the car out of town for the first time this past weekend 150 mile trip each way and had absolutely zero issues. My car has EDC and I prefer to ride in default "sport" mode and it rides just like OEM.

These are great! Very interested in seeing more pictures of them on the m3

Good to hear. If I were in the market for aftermarket springs the AC springs would be the ones I would choose. The drop looks perfect and I haven't heard any "floatiness" remarks compared to the Eibach's.

Depends on the offset and width of your wheels but the drop is minimal so more than likely will be ok. We have run 305's w the ACS Springs

What are the spring rate increases with these springs!? How much firmer / better handling realistically does the M3/M4 demonstrate with the ACS springs? Are they primarily for cosmetic enhancement or will they moderately improve handling / road course track performance too? thanks!

Not on stock wheels with no spacers

How do you like the performance of your springs compared to stock? Particular body movements/floatiness compared to factory suspension* ...EDC or standard suspension? Thx!

I would say the body roll is less and the car feels planted. I would best describe the ride as firm and predictable. I have EDC and leave the car in default "sport" mode 95% of the time.

Justin from Supreme took some great photos for me on the day of the install. Had the springs for about 2 weeks now, agree with the ride quality being close if not better than stock. Drop is not overly aggressive, in fact, after 2 weeks maybe a bit more drop on both the front and rear.

som current pics with drop ?

[mdefalco25]

supremepower since you have installed/seen both the AC S and Swift springs would you be able to share your experiences between the two? Also, from pics alone, the AC S look to sit a tad higher in the front but claim to have the same lowering specs of 25mm - 30mm as Swift. In your opinion, are they identical drops in front or would you say Swift lowers a little more? Interested in this information for my M3 before I decide on which to go with. Thanks!

Swift does lower a little bit more than the ACS. ACS is more comfortable too.

BBS FI-R ftw!

ACS I have installed & def comfy ride though drop @ front is not much rear is fine ..

[mdefalco25]

I wonder if AC S isn't posting accurate drop figures for the front. According to their information the drop is 25mm - 30mm. What's interesting is Swift springs state 25mm so if anything, you would think AC S would potentially be lower.

Hi, I'm also interested in that information, and are they compatible to the ZCP F83?
