Honestly the biggest PITA for dealing with suspension for me is jacking the car and getting the damn wheels off. HF electric impact gun + torque wrench mostly take care of the wheels but I need one of these to really speed up the process:



At ~$1350 it's at just the kind of price where I'd say "eff it". But I also want a new camera and exhaust which that would go a long way towards and which I would use a lot more. Its a toss up

Tokicos/KYBs are OEM replacements, so they would make the ride worse. Konis are worth it.

That is mainly due to good engineering by Infiniti/Nissan and good diagrams with suggested ride heights by Tein. It also helps to have a lift and air tools. Compressing the rear springs on the ground would be tricky.

Overall, the ride is excellent on the street. I doubted everyone who said they ride like stock as I have never had a set of coilovers ride anything like stock. The only road I notice any difference in ride is a newer road where the seams are not quite right. It does get a little bouncy, but still much better than any other coilover I have ever had. (I will update with track performance in the spring)

Fit & Finish: This is great as it has been with every Tein product I have had in the past. Everything fits well and is of good quality. This helped make the installation easy, especially with the diagrams and suggested ride heights.

Installation Tips: Do the front first as the rear are easier. Make sure you have a spring compressor to take off the stock front top hats. You will not need to re-use the spring compressor for the coilovers. There is a small steel plate on the front A-arms you can remove so you can just slide out the front shocks instead of disassembling the entire suspension. (Thank you Nissan/Infiniti engineers)

Use a lift with air tools and a tall jack stand to compress the rear spring. Set the rear spring height before installing the spring- they are much easier to adjust off of the car. The nuts for the rear top hats are inside the wheel well instead of in the trunk or behind the rear seats like usual.

Front



Rear



I put on the snow tires (painted stock '14 Evo rims) in 240/40/18 and it looks fine as it is two sizes less sidewall on the front. The stock rims and tires make it look slammed with the fat sidewalls. This is at the G37 coupe recommended settings.

Every DIY and tutorial I've been through and watched mentioned nothing about it. Then again the ones I watched weren't Tein so maybe it wasn't required on them.

EDIT: Found my answer. I will need one to swap over the stock front top mounts.
