I just put these coilovers on my car and I have to say I'm in love. They ride as well as the OEM shocks with the IMPUL springs and handle much better. I'm dropped 1.5 inches in the front and 1.25 in the back. It looks even all the way around. I made the dampening and the rebound so that the stiffness is about the same as stock. I think I will be able to get the camber and the toe back to factory spec during the alignment. What do you guys think about the camber and the toe am I doing to have an issue? Thanks. That being said I have a set of IMPUL springs up for sale if anyone is interested. PM for more info.Pics will be up when the car is clean in the next few days.

 

Camber will be tough, toe will probably be OK.

Are these true coilovers in the rear (spring mounted over shock)?

 

Because it's dropped below an inch? Yes, true coilovers.

 

Edit: the rear is true c/o (spooky)

 

Why do you say spooky?

 

Because the rear shock is only mounted with two 10mm nuts/bolts (IIRC). The size may be off a mm or two, but there are still only 2 bolts. In the conventional suspension setup, the spring carries its share of the load as does the shock. Now, with a true c/o rear (not only your brand but which ever brands have the same design), you're placing all that load and stress on a two point mounting system. Is the rear suspension mount able to handle that effective new stress load? I don't know, but I'm not taking that chance.

I'm not an engineer by any means, but no car I've ever owned with a true coil over shock rear suspension was ever mounted by 2 bolts. I've owned one with 3, but if my memory serves me right, most were 4. I, personally, am just not comfortable with the design although it may (and probably will) work.

It's just not for me.

 

Yes, anything lower than your Impul's is going to be difficult to get completely in spec. With that said, you should be in the -1.5 degrees of negative camber range, and with toe is spec you should be in pretty good shape for both tire wear and handling.

I was asking if it was a "true" coilover for this reason. It is something I have thought about, but just can't completely justify due to the above concerns. I have to believe that some engineering went into figuring out the load on the mounting points, but I would like to see a technical explanation to back it up. It does seem like a lot of stress and wear-and-tear for two small nuts.

Many people run this type of setup, and I have not heard of any issues, so I guess we will see....

 

I didn't install these myself, had them installed so I don't know. I may be wrong. I hear this was a good brand.

 

I agree. You will be adding load to an area that was never engineered to take the load from the springs. On my Evo, the front struts have 3 bots and the rear coilovers have 2 top bolts. But the Evo mounting studs are beefier M10 and take a 14mm nut. The G struts mount with smaller M8 studs with 12mm nuts.

 

I'm looking at the Ksport coils as an option. can anyone provide more detailed review? cheers!

 

How low can these coils go? I hear they can SLAM the car.

 

Sorry to bring back a thread that is a year old but I have a question.
I have ksport kontrol coilovers on my 07 g35 sedan and I want to adjust the rears without having to take the whole coilover off again. Is there a rear access "hole" in the trunk of the G35 to adjust the damping settings?
I change my ride height every other week for form on shows and meets. Please message me as I don't check the thread often.

And yes you can SLAM these coilovers. I ride on 19" with lopro tires and I am literally 1 inch off the ground!
