GROUND CONTROL Conversion Kit REVIEW

[West TX GT]

Any more feedback on these? I am finally ready to for suspension mods and researching everything I can before black Friday. These plus konis seem to be rather reasonably priced for a quality coilover system, especially if there is a black Friday sale. (Hint, hint)

I'll be posting a full follow up review in a day or so.

Do you have any insight as to suggested spring rates for HPDE/road course + daily - something I could live with on the street but don't mind it being stiff.

Probably their standard 300/800lbs should be nice for a DD/HPDE ride...

I can't wait! Did you upgrade from stock suspension?

Coming off Koni and sportline springs

Hey guys so I have an update after many man hours and adjustment. I started off with the standard 6 inch spring on my Koni yellows. As I previously mentioned we went down to a 5 inch spring which ended up not being usable as the spring ran into binding issues. We then went to a 5.5 inch spring at a 475 spring rate which ended up being a fantastic ride quality. I would say the front got down to 1.5 below stock ride height. Backs have more than enough adjustment. You can see the picture below for max low in front.

I personally run my car lower then most which is, again my personal preference. So I decided to go with the full coil over kit after all said and done, I mean heck had 80% of the kit already. This problem is the Koni/stock spring perch being in the way. The full kit is fantastic!! The ride quality is terrific. The handling I better then my sportline and Koni setup for sure. The height adjustment is probably the best I have seen on a coilover in some time. This thing could get you 2.5-3 inches below stock on a 5.5 spring... Which most wouldn't incline to do. Anyways, here's a pic of where I ended up my new 245/35 265/35 tire setup and adjustable camber on top. Alignment to come tomorrow to get that back corrected a bit. Kinda wishing I had that steeds rear camber kit right now but I'll wait for a sale.

I just ordered the 400lbs and 850lbs for my car. I already have the konis yellow. I also came from Sportlines and Koni and the ride was awful. Very very unbalanced and way too firm. It was eighter too soft or too firm. Never a balanced ride. Will see how this goes with the ground control.

@bbrfoot14

What spring rate are you running on the back?

I also want the same drop as the sportlines. I guess my front springs are 6".

850lb I believe

Am I correct in thinking you switched from regular koni yellows and the $499 conversion kit to the $1999 kit that that includes camber plates with their own custom Konis? If so, was there a major difference in ride or handling besides more height adjustment?

That's correct, but as I said I had the camber kit, springs and rear Koni's already.... So I only got the custom front struts. I would say that the full coil kit is more put together then the springs. Meaning the handling is better, the ride quality may be slightly harsher but let's attribute that to max rebound stiffness and extremely low ride height and overall it feels more connected.

Can you use Steeda front camber plates with these?

 

[Niz55]

Can you use Steeda front camber plates with these?

I am pretty sure you can.

 

[West TX GT]

I wonder how much the full coil over kit without camber plates would cost. Perhaps Ground Control can chime in.
