Swift Spec-R Springs For F87 M2

HP Autosport · 01-21-2018, 10:57 PM

How many here are looking for a linear rate sport spring? Swift Springs may have a set in the near future but needs to see how many are interested to move forward.

I believe I called and inquired about them...

As have many others. We need more people to show interest though.

What will the spring rates and drop be?

Not knowing how many people are interested in this the engineers aren't likely to get anything started or have any specs for us.

I'd buy!

Interested in options for track use with stock shocks.

What benefit is this over progressive springs?

Yes please. Pros & cons of both types. Personal experience as well.

From what i'm told, progressive springs start off softer initially and as they compress more they become stiffer. I can imagine that this is better for daily use and city driving as they are softer going over potholes and speed bumps and that sort of thing.

The idea is that they would be suited for both track and street use since they start off soft and then get stiff under heavier force. That would be the theoretical pro.

The con is that while they are suited for two purposes, it comes at the cost of performance. At the track or under heavy turning they require more force/time to fully compress/stiffen and this will add some body roll as a result.

Linear on the other hand compress evenly and while this may be harsher for daily use the performance benefits are better. It does one thing well and one thing poorly vs having the kind of decent all around ability progressive springs would have.

In summation, linear are more performance oriented, and progressive would be more comfort oriented.

That's how i understand it. Feel free to correct me.

TampaF87 · 01-25-2018, 12:25 PM

^ this is true.

I would describe linear as being more predictable as well. you know exactly how the suspension is going to react, because it does the same way during all situations, assuming everything else is equal. Linear is less supple, more predictable. Progressive is more comfort and compromise. It's all about what you want out of the car.

Some good discussion going on here!

Thanks for that clear and excellent explanation.

Swift Springs is monitors this thread so hopefully, they will start working on something soon.

NashvilleM2 · 02-02-2018, 11:36 PM

I would definitely be interested! I had Swift's on a previous car and loved them.

cookiesowns · 02-05-2018, 02:13 AM

Would be interested for the M2 Mperf coilovers!

As long as the M Performance coilovers take OE profile springs. Otherwise, Swift offers metric coilover springs if you are looking to upgrade.
