Well. Im running KMAC springs. They are progressive, which in essance means the spring rate is not static. I went with a 5kg/mm front and 4kg/mm rear (ae86) and I can tell you that their spring rates are stiffer than other brands. Maybe this is because their method of making them to custom specs meant that they used 5kg/mm as the lowest possible rate and variations increase the rate over 5, rather than using 5 as an average.
Ofcourse Im speculating, because they really do seem stiff. But theyre a good price, and the guy who makes them is a good bloke. They do their job.

KMac springs are extremely stiff.
I have them on my car (also lowered 2") and it's like not having any suspension at all.
Just a warning. I like it, but it's not everyone's cup of tea.

stiffer = more bounce ?
that doesnt really make sense to me..
if they're stiff, that means they're harder to compress right.. ?
that way less bounce right.. ?
if they're soft springs... then they tend to be more .. how would u say... easily forced down.
i can't seem to find the words..
but maybe u can figure it out from what i'm saying..
is this wrong ?

When you go over a bump (not a pothole a bump) this will cause your spring to compress and your dampers will keep these springs in check (so to speak) by also compressing. This will absorb the shock of the bump, say the bump happened to be a 10cm mound of bubbled concreate. Your dampers and springs will compress so this 10cm bump will be absorbed. Picture a car with no springs and shocks. The entire front end of the car would launch 10cm off the ground, followed by the rear.
If you run higher spring rates, the spring wont compress as much, so where is this force of the 10cm bump going to go? basically the force will be split up (some into the spring/dampers) and the rest will slightly compress the tire and moreso you'll feel this effect in the car. Hence.. a bumpy ride.
Im guessing your referring to roll (or perhaps 'floatyness') with soft springs. If springs are too soft yes it will bounce.. but it will be more of a floaty effect the bounce will be created from springs compressing and decompressing over a few metres, you really dont know the meaning of a 'bump' in the road until youve been in a car with a race-spec spring rate on the road.

Hi,
I went to KMAC last month and got a custom rear sway bar made. The standard TA22 wouldn't fit on the RA25 'cos of the larger LSD. Also, I didn't want holes drilled into the chasis. So, they customed one, on the spot, and used the existing manufacturing holes in the chasis-rails. Cost the same as a standard bar and they're very helpful.
Sorry if this is a hijack 'cos you're talking about springs, but I thought I'd let you know they're (KMAC) pretty good with custom requests.

Yeah I was speaking to Kevin MACintyre the other day. He's answer to availability was "Yes - if we don't have it, we will make it for you" Excellent business sense in my mind, and yes I love their springs and swaybars too!

I've got a set of KMac 1.5" low in my sx, they aren't much stiffer than standard. Was running 2" low KMac that I got from these forums that were VERY stiff. Tell 'em what u want and they'll make it for you. Good customer service too and not too expensive.

depends what you want, stiffer springs generally equals less roll, more grip, better handling etc. but at the expense of ride comfort and a few other things. very stiff springs could give you less grip in some situations, like accelerating from a standing start (less squat/weight transfer) and over mid-corner bumps. you will most likely have to compromise on something no matter which springs you choose.
