Default 1st gen FM springs too short?

I just installed a set of 1st gen FM springs on my Konis. I have FCM mounts and bumpstops also. The springs are loose enough to move around. I didn't even need to compress them to put the mounts on.

It doesn't take much pressure to move the mount down to the top of the spring. It is maybe 4-6mm away. Is this normal? I'm going to try putting it in to see if the suspension is tight enough to simply hold them together.

EDIT: The Konis are on the highest perch as per the FCM instructions. I would call Shaikh, but I think the springs are the problem not the mounts.

Damn it, this should have been in the suspension forum. I forgot we have that now.

I went and put everything together. I made sure to torque the bolts under load and to proper spec. The springs are tight when in the air, but when I put the wheel on it sags a 1-2mm. It's not enough to come out of the perches like before, so I'm ok with it.

The car looks GOOD. I can't wait to see how it handles.

Think about it. You are going to a much shorter spring, it's no surprise that under full droop you run out of spring. That's why you see some coilovers with helper springs.

My GC/AGX setup does the same thing, I've never had a problem since I don't often get the car airborn.

It does make sense, but i was afraid of it before I installed them. The spring could come out of the perches. I was afraid of the car being able to move enough to let the spring come out. After installing it I see that is not possible.

Thanks for letting me know its ok though.

Well, at least you didn't do what another MT forum member did and put the springs on the wrong end... F on R and R on F.... and THEN call me and ask which springs go where.

At work everyone kept telling me the longer ones go upfront. I kept telling them the longer ones came OFF the back, why would they go on the front? That was annoying to deal with all day.

Same here on tokico/gc.

And the sizes confused me. Shorter spring on front with longer shock. Had to compare pn w/ springs

stiff springs = less need for travel

Thanks to The_pipefather my car runs! He managed to sort out the MS, so I got to take it for a drive. I will be taking pictures tommorow of how it sits. I'm sure everyone is bored of seeing it sitting in my driveway, so I will go find some decent looking spot. I love the stance it has.

With the FCM mounts and bumpstops I have all the travel I will ever need. That being said I doubt the springs even compress...they are STIFF. It's ok though, I like it that way.
