Upgrading Megan racing coilovers advice needed

I have a set of megan racing coilovers, and am trying to get a smoother ride. I have the regular springs on them.

After searching and reading and searching more, has anyone put the upgraded springs on(10K) and found the ride to be more harsh?

 

I am finding that when I go over bumps I hear a loud clunk that sounds like my sidewall on my tire is a 30 series. Before I get the "tighten down the strut nut, your camber plates are loose" I am using factory top hats.

 

The bumps that cause this problem are usually sharp bumps, like that of tar that has rippled up or a bad approach to train tracks. Normal bumps, like on the free way don't give me problems nor do those same bumps at lower speeds.

 

The idea is to get a low spring rate helper spring to make my ride more like stock(and like kw's) I know the kw's have better valving, but how?

 

It doesn't bounce after i hit a bump, o I don't "think" I am under dampening, but I am at full soft.

 

Anyone that can give me some useful information (not the "you should have bought KW's...) would be appreciated. I know I didn't get the best set of coilovers, but I would think that it should be possible to improve the ride.

 

Just using the factory front top hats increased the ride quality night and day, so I think there should be room to improve.

 

Also, my preload is hand tight plus a half turn, then locked.

 

Thanks!

You'll want to go down in spring rate, not up. An 8k spring is fairly stiff for our cars to begin with so going to a 10 will only make it worse.

Wimp! Stiffer springs are better.

Thats what I thought, but I have seen people post that the spring rate doesn't change the ride and that its only dampening. I don't want to go to a 10K, but if someone has and compare it to the stock MR spring, you could assume that going down in spring rate would have the opposite effect.

Wimp! Stiffer springs are better.

I'll let my wife know, she is the one who has the problem with it. :lol:

Lower spring rate = softer.

 

What size tires do you have?

225/40R18

I don't think I can go wider that 225, since my current rims are not wide enough. I have a set in the garage that I am going to see if I can mount wider tires.

I know I can go to a 45 series, which would help with comfort, but I would be changing my odometer. I may go 215/45R18, which would only increase it by a bit... who knows...

7.5 inch rims in the garage, cant go wider than 225 unless I want a 245/45 which would put my odometer way off...
