How much do konis run? I think they would make ride nonbouncy

I looked into substituting Konis in. It's definitely doable. I made a thread here:

https://www.myg37.com/forums/brakes-...-location.html

All we would need is the locking circlip for the front Koni shock and a 2.5" ID spring sleeve + collar. Would probably cost ~$1100; another $200 if you wanted to change the spring rates. Basis Zs are working for me now but if they ever blow I'm going this route.

Konis will work much better. They are adjustable and their rates are perfect... strong body control and supple bump absorption. They've been great on every car I've had them on.

This is using the Koni yellow shocks for the 370Z like they have listed on tirerack? What springs would you use?

I can vouch for Koni's ride. I had some Koni inserts on a WRX and they were great. Rode well on the street and you could tighten them up for track days. I did blow one out on a track that had a dip in it and they sent me a new one. The lifetime warranty is always a bonus.

Yes they are those shocks. I'd probably get 600/500lb springs. Up front I think they are 8x2.5", out back they are 9.5x5.5".

Has anyone tried this yet? I am starting to consider this for the front as I hope it would make the car smoother on the newer wavy roads. Where do you go for the circlip, spring sleeve, and collar? Would we need any additional parts for the rear suspension?

I can't post the link now, but you will need a Koni circlip, sleeve kit and I believe a 2.25 or 2.5 ID spring of your choosing. I'm personally still leaning towards the Flex Zs as they are cheaper and close to the specs I want.

Yes, I have that info. you provided earlier quoted in my post. I was just wondering where to obtain those parts.

Full soft is stiffer than stock and a good starting point, I've tightened them a full turn and it was too stiff. No bouncing and they're great an handling dips and elevation changes. Obviously pot holes and stuff like that hit harder.

Downside: rears are tough to adjust on the car.

The lower spring perch can be mounted upside down, which years ago caused people to believe they raised the ride height, but were ultimately installed incorrectly.

That's good to hear. The only thing I am not in love with on the Tein Basis is how bouncy they are on newer roads that are kind of wavy. They actually handle bumps ok, but they do bounce a bit. It would also be nice to be able to adjust them differently for street/track.

What springs do you run Lego?
