FK8 Master Spring Thread!

[thavens]

Swift sent us this picture of the final Spec R springs. Don't have spring rates or an exact date of release, buttttt it will be a true 1 inch drop all around and the first batch will be arriving early next year.

Also we were given the green light to start taking pre-orders

Price for pre-order Hippie!? lol

Does someone already knows the spring rates of H&R springs?

Edit:
Got the rates from H&R!!

H&R:
Front: -4.5 kgf/mm (44 N/mm)
Rear: -5.1 kgf/mm (50 N/mm)

Interesting is that front is softer than OEM?!

You will get less understeer or more oversteer compared to stock.

But why is than Eibach front stiffer than OEM. That would result in more understeer with Eibach?!

eibach increased the rates for both front AND rear by a similiar amount so it shouldn't change the characteristics of the car. Swift on the other hand has a stiffer rear compared to the front which results in little more oversteer or less understeer than stock. Possibly to combat the understeering characteristics of the FWD car. While I personally felt the car does like to rotate decently for it being FWD and can possibly make it rotate more with a rear sway bar, I don't doubt swift's intentions to make the rates the way they are.

Above reasoning is sound...there has to be a reason why Swift is doing this...I'm waiting a bit more, as I still want similar spring rate as stock, but just a little lowered.

Only reading reviews about the Eibach springs, would be interesting to hear some H&R reviews too But I guess Eibach is in the US more popular than H&R (in europe it's the opposite).

thanks for the heads up. I'll see if I can get some spring rate values but its a 0.8 inch drop and I found some pictures:

According to Eibach, this is what the rates are.

Front : 5.2 kg/mm
Rear (progressive) : 4.9kg/mm

Received this from H&R today:

oh and H&R uses a progressive spring rate, I assume they sent out an average. Even so it's interested to have someone test these on the track, to see how it affects the balance of the car since they seem to be banking on correcting understeer

oh derp lol. ignore me

lol no worries, I wasn't very clear

Also Tein seems to be looking into the Type R:
