Review Tein Basis coilovers on '13 G37S sedan 6spd
#91
Me and my brother in law did it. Not to hard a job as far as complexity, just a good amount of wrenching. Took us about 6 hours.
Here is a pic

There’s another thread some members talking about switching out shock to Koni Yellows- is yr ride stuff? I can feel certain bumps on road
My front right camber like knock on certain bumps when I’m going to fast or once in awhile have all 5 fam in the car & hit a certain bump
Looking to do sway bars next- is hotchis or eibachs better

Thanks! Mine are not stiff at all. It does right tighter. I have Eibach Sways and think that adds some stiffness to ride. I dont know about hotchis. Im thinking unless you race its not going to be that noticable. Maybe someone else can chime in

My rears probably dropped 1/2-3/4" so I got some spring spacers for 5.5" OD springs. I had to cut them a little short to fit, but once I did that they worked great. Actually, once I raised the rear, my FUCA clearance issues seemed to have gone away and I think the front raised a little bit. Left rear corner was sagging worse than the right.
Ultimately though I think the real issue is these coilovers were designed to ride soft on the Z, and we are using them on the 500lb heavier G. I think once these die out I'm either going to move up to the Flex Zs or build a custom set of Koni coilovers with 12/10k springs. The old Flexes look pretty digressive but I trust Koni way more and have learned from experience that it pays to do things right the firs time.
Still though I commute ~400 miles a week on mixed roads and these work great. Well balanced and a great value but there are definitely some caveats.

Raising the rear will lower the front, not raise it. Weight transfer, ya know?
And upon further reflection, I realize I didn't consider anti-dive geometry. I don't know how much is built into the suspension and there might be enough to raise the front slightly when raising the rear.
A good test would be to get three buddies into your car and see if the extra front clearance goes away when the rear sags.

Raising one corner will lift the closest corners. Everything pivots around the other corner.
Also when you jack up one end of the car the other end lifts too. I imagine the same happens for small adjustments on coilovers.

Won't we have the same issue with any aftermarket suspension since it will more than likely be designed for a lighter 370Z or G coupe, instead of a sedan?

Can you post a link to the Koni thread you are talking about. I have been considering the same thing as it might be nice to have a smoother ride on the street and be able to tighten it up on the road. Not sure which springs would work well though.
Gladly. I had Eibach sways on my Evo and the bushings would dry out pretty regularly and squeal like crazy. I tried every kind of grease known to man until I discovered some waterproof marine grease. This seemed to work. Hotchkis sways have grease ports with zerk fittings so it is much easier to keep the bushings from drying out.
