I am currently running

-H&R Sport Springs
-Koni Yellows
-ITR 22mm Rear Swaybar
-4 Point Neuspeed Strut Bar
-Falken Azenis Tires
-Other chassis stiffening bars

I know the limits of my car and the suspension from auto-x, and I want something that will handle better. I was thinking of following the Ground Control and Koni Yellow route, since I already have the Koni's. Will the Ground Control's increase the limit by a lot?

What characteristics did owners of H&R/Koni see when you changed to GC/Koni?

What spring rates would you recommend? I was thinking 400F/500R, but will that cause too much rotation? Is the read bearable on the streets? I don't mind a stiff suspension, but what do you guys think?

I have rode in a EK Civic with Spoon Show 16KF and 14K rear, and I thought it would be really really bad on the streets, but it turned out to be quite bearable.

I don't know, what do you guys think?

 

Holy crap that's almost 900lb/in in front and 800 in back!

500 is pushing the limit of what the OTS Konis can handle. I plan on going with 350F/400R.

I rode in my friend's EK w/ Konis and GC 450F/350R and it seemed fine, but I really can't compare until I can drive my car and then his car back to back on some really rough roads, which is pretty much ever road where I live.

 

Yeah, superstiff and sometimes bouncey.

The car is much less likely to understeer at the limit. The car feels much more balanced than with the H&R's. I wouldn't go past 450 to 500 lb/in for the spring rate. My Tein S'tech springs were somewhere in that vicinity and i don't think the OTS konis handled it too well. Just remember the rear rate will affect the ride quality more than the fronts will so choose wisely. Or you could buy another set of rear springs with different rates.

 

OTS Koni Yellows can handle a MAX of 400lbs/in a Koni representative told me.., any higher than that and your exceeding its efficency and lowering the life of the shock.

 

I love my 400/500 setup with ITR rear swybar (22mm).

The 23mm rearsway came in today.

One of the most important factors of the equation is tires. The Yokohama ES100's come highly recommended from me for their grip.

As for the ride. I have the Yellows on nearly full stiff. It's a little bouncy, but then again the roads here aren't exactly smooth pavement all the time. Several passengers have mentioned "getting air" off some of the bumps in the road

 

Okay that brings up another crtical issue.

Why do some go for rear heavy spring rates. IE: 400/500 vs front heavy 500/400 spring rates? Which one is better in a sense?

 

that's a great question, there really is no answer for everyone. it depends on what you're trying to achieve.

Personally:

I like the 400/500 setup. I like oversteer/rotation/throttle lift control. I also like a good ride! For these reasons I recommend the 400/500 setup based upon first hand aggressive driving experience.

All this being said it's the tires that really make the difference once this setup is in place.

 

First off, if you get GC's, you have to buy a new set of Koni's...Koni makes a special body to mate with the GC. I would check Ground Control's site and look at the footnotes about running Koni's with their coilovers. Stick with springs/Koni.

no, you buy GC's with adapters that go on Konis.

I know because my friend just replaced his H&R Sports w/ GC sleeves for Konis.

 

the GC's have a black insert on the inside that mates to the Koni snap-ring already on the shock body.

just to update a bit...with the more aggressive front pads I can now really make the rear rotate when braking
