Got coilovers, now which Struts?

[2slo95fiveoh]

I just recieved my MMR coilover kit (QA1 springs) in the mail.. The springs are 12" with a 350lb spring rate. Now i need to decide
on which struts I will go with.. I already have a tubular Kmember, and plan on getting Tubular A-arms, as well as MM 4 bolt c/c plates
within the next month. The car will mostly be on the street, but I plan on road racing it appox once a month.
I am leaning towards an adjustable strut, and was looking at Strange, but i hear they are noisy? Any suggestions for Strut brands?
And also, since i plan on lowering the car with the coilovers, should i go with Fox length struts?

I'd say you should go with Koni Single Adjustable. From what I've been hearing, they will actually be able to valve a lot of spring rate right off the shelf. 350 lbs is probably the most it will take though. If I were you, I would not go with spring that stiff in the front. You will most likely have understeer issues if you try to combine that with any off-shelf rear spring. I'm running the stiffest off-shelf springs that 4 link allows (H&R Super Race), and I coupled it with a 275 front coil-over.

I see. Good call on the Konis, MM website claims their preferred spring rate is 275-375, so you were right on the money. $400/pr is
a little steeper than i thought i would spend, but I don't mind bitting the bullet if it will be worthwhile.. As far as the 350 spring rate, it
was what MMR recommended for my 95% street, 5% road course driving, so that frustrates me slightly that it might
be a bit too stiff, but i suppose i can always buy different springs if i don't like them.
How are the Koni single adj as far as noise go? Driving my car on the street mostly i don't want to hear a squeek everytime i hit a small pebble.

They are quiet. I drive my car close to 20k miles a year, and believe me when I say this, I would not tolerate it, if it would be obnoxious. Try looking online as well. I got my Konis 2 years ago for 520 shipped, and that was for all four.

On spring rate. I'm sure that 350 pound spring would be bitchin' at the track, but the problem is that you have to have a 250 pound coilover spring in the rear to keep the car handling neutrally. 250 coilover rate is 550 pound spring in stock location. According to Maximum Motorsports, 4 link does not utilize that spring rate well at all, so to keep that spring planted you will need a torque arm. I don't know what you are running in the rear, but I'm almost 100% sure that 350 front will be overkill until you stiffen the rear up.

Ok, I ended up calling MMR and there was somehow a miscommunication as far as my proper spring rate goes.. So i shipped my 350lb springs
back today, and am getting 275lb springs in return.. Would the Koni SAs still be my best bet?

Works for me.
