What is the best suspension for improve handling and lap times?

AlWakRa

First, seat time, as 370z is well balanced car from factory.

Then, you should look into upgrading your brakes to not face any brake fade.

As suspension, you would start with alignment kit, like OptionZero suggested, with FUCA and RCL, getting more camber and better tires, you would improve your car a lot. Changing the LSD would also improve the car predictability and exit speed.

You can get swaybars next.

Those would bring the best out of the car, as the stock suspension is well balanced.

How much track time do you have and what mods have you done to the Z so far?

May be 2 weeks 1 time, my goal just want to improve the car's handling.

Rusty

So.....you not have a lot of track time and did nothing to the Z yet.

1. Get time behind the wheel to improve yourself first.
2. As you improve. You will find out what areas of the car needs up-graded first.
3. The first thing most do is to read this thread.

Not sure what this means exactly 2 weekends once, 2 events once, or 14 days?

You haven't said what if any mods you have? Do you even have a helmet or do you rent one?

Take some time, maybe even like 10 minutes and write a reply more then a few words so the people here can properly help you and potentially save you from a 3 thousand dollar mistake.

Thanks! It is really helpful!

Do you know some suspension build from Amuse and MCR? I watch some video from hot version and I find out that Amuse and MCR is really fast in track. But, why it is rare to find people use their coilovers?

CRiZO

Amuse and Zeal (MCR) coilovers are probably twice the price of KW V3's I'd guess.

gzw123

Yeah, but how much performance different between them? Is that worth it?

OptionZero

For you, no.

The difference between something in the sub $2000 range (Fortune, BC, Powertrix, etc) and something higher (AST, Aragosta, Ohlins, etc) is largely irrelevant for a total novice

Nothing is gonna change your track experience more than . . . track experience at this stage.

When you can maximize your car in its current state, then you can move to a higher level of suspension (or power)

For now, you should be focused on safety equipment and some basic wear items like pads and tires that get chewed up on the track over time

The japanese brands you are referencing are just that - exotic japanese brands. They aren't going to have any USA support. If something breaks, expect a long and difficult road to replacement.

Thats why i am recommending Fortune - they can rebuild it for you stateside. Ditto for Powertrix. I think BC does too. All these places can also do swift springs as an upgrade in whatever rate you want.

Before you throw money at big name parts you need to consider where you currently are experience-wise.

I will repeat:
The most important thing for you is seat time.
I'd also add that you should get seat time at a couple different tracks too


EDIT:

This used set of KW's looks pretty good too

KW Variant 3 coilovers, custom setup

Thank you so much! It is really helpful, I will do more practice in summer time!

AlWakRa

I had Zeal (MCR) coilovers (got them from Japan, they are reasonably priced over there if the jpy rate is low), they are pretty nice coilovers and did very well, but I got into accident and apparently they got affected by it and at the end I returned to stock, now thinking about which coilover to go for, looking at custom ones, I am looking at MCA Red and Fortune Auto 500, don't want to overspend, as I cannot rebuild the suspension, the shipping cost could reach the price of a new coilover kit.
