^ thats cool

As we have sufficient numbers on the list, it would be good if we could start discussing what spring rates you guys want. Basically, would need to know:

1) application/usage
2) suspension modifications (i.e swaybars, as these hugely affect the balance)

Thanks!

Stock Eunos Presso Spring rates (EC8S)are;
Front: 3.07kgf/mm (or 172lbs/in)
Rear: 1.87kgf/mm (or 104lbs/in)

The Mazdaspeed (Eibach NOT Pro-Kit) BG road spring was;
Front: 3.3kgf/mm
Rear: 2.2kgf/mm

The HR Springs for the Eunos Presso etc are;
Front: 3.93kgf/mm
Rear: 3.21kgf/mm

I have over time run thePresso with all of the above springs and all with the Koni Adjustable strut insert upgrade and the MS Eibach and HR springs with a Whiteline (solid) rear sway bar.

My preference would be for YCW's supplied with a "sport" spring Front NO more than 4.5kgf/mm and Rear 3.0kgf/mm. The sway bar upgrade stiffens the rear up enough (IMO).

I don't know much about spring rates but what I do know is that when I'm accelerating hard the back of the car squats a lot. I would want something which would keep the car stable during acceleration but not stupid and bouncy.

I'm currently running Eibach springs on KYB ZX2 struts. The ride height is superb and quality / handling excellent.

Update

The development set is now ready:


Differences between development & production

As this is only a development set, the initial aim of this set is to test for fitment first and foremost. The differences are:

- Colour: Final colour will be our Red as shown in this image:


- Top Mounts: These are just off-the-shelf parts supplied to us from our partner factory so that we can test the fitment. They are camber adjustable, but lack the caster adjustment. For production, we machine all of our own mounts in-house, and will have both Camber & Caster adjustability (mounts shown in image above)
- Upper Spring Perch: These are just off-the-shelf parts supplied to us from our partner factory so that we can test the fitment. They lack the radial bearing. For production, we machine all of our own perches in-house, and will have the radial bearing (spring perch shown in image above)
- Collars: These are just off-the-shelf parts supplied to us from our partner factory so that we can test the fitment and are a generic style. For production, we machine all of our own perches in-house, and will be slightly different (shown in image above)

The actual damper & internals are the same as what will be used on the production sets:


As the damper will be unchanged, the tester will receive the "production" parts to replace/upgrade the development set after fitment testing is complete.

I would encourage you to design the top plates with static increased castor. rather than make it an adjustable point.
none of the BG or BF chassis cars need castor adjustability. a static increase only is plenty sufficient and would retain strength- for those who... persay tend to be a bit harder on their chassis.

This is really cool. Good job MFactory damn, I have to shave down my knuckles strut mounts for these to work on my car. That color red would go good with the color scheme I am going for. Much rather support you than the others. Would you have a good setup for the daily driver weekend warrior setup going both drag racing and autocross? More of a curiosity thing considering the way things have been going lately I'll put you down on a list for my car but that'd probably be after group buy. They will be going for $1500 after that point and they'll still be available?
