Ground Control Spring Coilover Kit REVIEW

Just pulled the trigger on this as well. Jay was super helpful and I think we put together a system that will definitely suit my needs.

Yes! When is your kit expected to arrive? Where do you plan on doing the install?

It's arriving next Monday. Hopefully, If I'm not busy installing them next weekend. I'll keep you posted!

Can't wait to see the results.

Very true! I just received mines today! I didn't come with any installation guide. Does anyone here have the instructions for the front? They sent the one for the rear. I'm planning to have it on my car on Wednesday.

Excellent review!

Who is doing the installation? Probably would have them call Ground Control and have the instructions emailed. Good luck. I too am very interested in this approach.

My friend and I will be doing the installation. It looks very straight forward. I had some questions about some additional bushing the package came with and how the GC front perch are installed on the struts. I'll call them later today to get more clarifications.

Congrats! Would love to see the results after you do the install.

When is your kit arriving?

Jay is waiting on some special low profile parts (to ensure clearance for my front track wheels/tires) that should arrive later this week. At that point, he'll ship it out. My guess is that I'll get it sometime next week, though probably not in time for the 5/27 track day.

The front is a 6" long 2.5" ID spring with a rate of 440 #/inch.
The rear is an 8" long 2.5" ID spring with a rate of 600 #/inch.

I still haven't installed mines. I'll get you the info later!

The kit that I'll be getting is 440 front and 600 rear. Still waiting on the low profile adjuster nuts. Should ship out early next week.
