I am facing some similar challenges trying balance street and track goals, albeit not as serious as this thread. Looks like all I need is more money lol

Well done OP

This picture alone is . . . amazeballs

It looks like all the front facia openings are directing air to coolers - where is your brake ducting coming from?

I see what I assume are custom, rectagular inlets on the lower left/right corner below each DYRL , where are those going?

Cut-outs below DRL's are for oil coolers, with outlets in wheel arches. Brake ducting cut-outs are more to the center.

Brakes cooling with 2.5 inch ducting.

The 3" brake duct hose is a PITA to route.

Brilliant

Wow! amazing build!

Fantastic build! Definitely going to be looking to your car for inspiration. How did you go about extending the steering column?

Stock steering rack is already telescopic in 370Z. It's just a matter of extending it to its maximum position and then making a bracket to lock it in the new position. It's not very hard, but this mod (together with lowering recaro seats), was a game changer in terms of seating position - you can now seat lower and further back and still have a steering wheel close to you.

the only drawback from this solution is that the extended steering column looks strange through front windshield with that huge gap, but to I don't really mind it to be honest.

Sharing suspension upgrade.

Old coilovers (KW V3):

New coilovers (Custom made 3-way, made using similar components to AST/Moton, but with even higher adjustability):

I'm starting with spring rates of 16kg front / 7 kg rear. Just in case that will be too soft, I bought extra set of springs (18kg front / 8 kg rear).

Will post an update after first track session.

Here is a video how badly KW V3 was performing on track, especially on slicks. KW is a great street suspension, but for serious track use I don't recommend it:

Sucks KW never made ClubSport version for the Z34. I've heard people complaining V3 being too soft more serious track use.

Yes indeed. My friend has KW ClubSport on 350Z and that suspension is in completely different league to KW V3. Here is a video of how much better it performs:

Clubsport is a real deal. In opposite to KW V3, it's tuned on Nurburgring, it has much stiffer, linear springs and proper top mounts. Clubsport is well suited also for trackdays, while V3 is strictly street suspension

How exactly did you pull out the steering wheel from the stock? I thought it was only adjustable up-down, not telescopic.

Steering rack is telescopic, just not adjustable out of the factory. I didn't do it myself, but from what my mechanic have told me, all he did was extend stock steering rack (100% it's telescopic) and he fabricated a bracket to lock it in the new, extended position. I'll ask him for more details and I'll post an update
