Received my 17+ Honda Civic SI Swift Spec-R Sport Springs today.
Part number:4H918R
4kg Front spring
5.7kg Rear spring
1.1" drop all the way around
Here's what you get.
The installation process is fairly easy.
The rear is quick and simple.
These took me around 20 mins, first time with observing and documenting.
With the rear of the car supported and wheels removed,
Remove the rear sway bar link 12mm.
Remove the lower control arm bolt 17mm.
Push springs bucket down.
Remove spring, transfer spring seat/ insulator.
Reassemble.
The front is a little more challenging.
This took me around an hour and a half.
With the front of the car supported and wheels removed,
Remove both sides sway bar link from strut assembly 14mm nut.
Remove the brake line brackets and electrical connectors 12mm bolts+pliers
Remove the 3x 17mm nuts that secure the lower ball joint to lower control arm.
Remove 17mm bolt holding strut to spindle hub assembly.
Support spindle hub assembly.
Remove 3 14mm strut mount nuts.
Place a shop towel/rag/old shirt between the cv axle boot and lower control arm.
Push down on lower control arm removing ball joint.
Push down on spindle hub assembly. You may need to tap on it with a soft dead blow.
Remove strut assembly from vehicle and support spindle hub assembly.
Use spring compressor to compress spring.
Swap springs, no bump stop trimming required.
Reassemble.
There are a few DIYs on here and youtube that should be able to help with the spring installation.
I can upload more photos of install if requested.
