A shame, but most want that slammed look so I understand swift has to make what sells
Swift will certainly entertain your idea of a custom set of springs if you so choose. Give them a call.

I may do that, depending on price

Maybe you can help with determining ideal spring rates?

I too am a BIG fan of the SWIFT SPEC-R set-up. I track my car often, and these springs brought increased stability at turn-in and transitions over the OEM ZCP set-up. The daily ride quality is also great (even 2 yrs. later). I use the "Normal" setting mostly, and it's not too stiff or jarring at all - very OEM like earlier mentioned.

I am very glad that SWIFT is developing these for the F8x platform much earlier and that they'll be out by Q1 '15 at the latest. I think everyone here will be very very happy with these springs. This set-up should give you full confidence you are "improving" the suspension, and not simply riding on bumpstops / improving the "looks". Two thumbs up for SWIFT!

Harold, what do you think about adding Camber Plates to the F8x platform, do you have recommendations on the best set out there to consider?

It doesn't look possible to make a camber plate for the F8x to be used with stock profile springs.

Are you saying one must go KW Clubsport 2-way with CPs, and could not go modded springs + something like a Ground Control CP set-up? If so, why? What are you seeing in the set-up that makes you think this?

M4 fitment has not been test fitted so we are looking at least the first quarter of 2015 for these springs.

What do you not like about the H&R in the different damper settings?
Any news on the M4 fitment?

Give Swift a call. They are doing the M4 test fitment in-house.

Swift used my M4 to test fit their springs. I'm sorry about the delay...I know everyone has been waiting a while for this happen. The VPC held my car for one month...

They were installed and measured yesterday. I think everyone is going to be very happy with the drop and ride quality with these. I have the passive suspension and don't really notice any difference in ride quality (maybe a little more firmer ride but not in a bad way). After I get to drive the car more I'll report back with more comments.

The car now has a little less than a 2 finger gap in the front and 1 finger gap in the rear. Here's a basic picture of how my car sits now with 12.5mm spacers in the front and 10mm in the rear.

I'm still hoping they don't drop the rear at all or max of 1/4".

The car in the front needs a slight drop but the stock rear height is perfect.

Nice. I've been waiting for springs with a more mild drop than the H&Rs. Can't wait for these and the Eibachs to be released so I finally have options that fit what I'm looking for.

Swift springs are focused on performance

One thing most people, and I, often forget is that lowering can affect weight distribution. You cannot only drop the front and maintain the same weight distribution. The car would become more nose heavy, handle worse, understeer more and ride worse.

The car needs to have the same ratio of drop front and rear as stock to maintain this balance. I certainly wouldn't want even more front weight bias.

That said, these are promising...

Kenny, I daily drive this so do you think I should just go with H&R sport? maybe 2-4 track days a year. but I still have my other M3 to do it.

Is the 12.5/10mm spacer the most aggressive combination without rubbing? Is 15f/r20 feasible?
