Let's see if this works: https://www.fitfreak.net/g/album/7586768

 

i can see your photo album. Nice pics! So have you purchased the BC Coils yet? After riding on my new suspension, i can honestly say im impressed. Didnt sacrifice ALL the ride comfort, and still rides smooth. Body roll has decreased significantly, and turns nice and tight on the on/off ramps. The only problem is when i have a full ride. The rear rubs at turns when I have a combined 300lbs in the back, or even if i have a 200lb+ person up front. (Note i am small on stature, 5'4" 142lbs, best for racing hehe). I am thinking I should have just gone straight to Buddy Clubs N+ specs 😥😥, just because I remember the feeling on rails.. but at the same time.. the GK is the daily.. need that ride comfort somewhere..

i also noticed your car was purchased at Honda Oakland.. i purchased my (at the time) 2013 Civic So brand new there.. miss that car =( and you have a silver fit as well! Cheers!

 

Add another set of spring numbers, Megan Racing.

Front 2.67kg, rear 3kg
Front drop .875" rear 1"

 

Don't get the Tein springs, those are trash. I bought a set and it was awful. The spring drop the car way lower then the swift and the rebound felt like it was made for a shock have the stock size. My car was jumping on bumps instead of bouncing. Then i switch over to swift spring and it felt alot better.
