Before tearing the car completely apart sometime next year, I’m trying to repair, retrofit, modify, optimize a few things.
As the car wasn’t that nice to drive, first thing was to remove the cut springs and replace them by some new ones of the same brand. Of course it now looks a bit high, imho, but it drives way better. Cut springs had no preload at all, dampers had only about 3/4 inch of travel and the slightest compression would let it sit on it’s bumpstops. For comparision:
As it sits with the new springs, the rear is OK, the front would aesthetically benefit of a slight drop.
I also removed the worn aftermarket steering wheel and fitted my Nardi ‘deep’ which I had laying around. Unfortunately I did not have a matching horn button. I’m not sure what steering wheel I’ll mount after the resto, I'm tending towards a Datsun Compe wheel or a Nardi black and wood.
I sourced a non series 1 driveshaft, moustache bar and rear transverse link. This is all thats needed to change the rear drivetrain to the later geometry. While at it I also changed the diff support for a hangingt RT diffmount. No more diff straps or rubber bumpers for Tosbo.
In my quest to optimize the driving sensation a bit more, the car needed a rear swaybar. As it hadn’t any at all. I ordered a complete ST suspensions swaybar set from the US.
And the biggie, something most will probably not understand. I got rid of the Webers. I love simple things, things that can be mended during a road trip, things that are set and forget and most of all, things that are driveable under pretty much every condition. So I removed my 40DCOEs and got myself a set of nicely refurbed Hitachi 4screws with an early airbox.
And yes, the car drives a lot smoother with minimal load (under 2500rpm) and around town with the stock SU. As I had 1 240Z with SU and this one with Webers, it was easy to compare. And I just prefered driving the SU. Above 5000rpm the Webers are way better though.
As for the issue with the uneven front/rear drop: The easiest way to gain a bit more low at the front an be able to dial in a bit of camber are some camber plates from SilverMine, which are in fact just Mookeh camber plates with studs mounted in the right pattern which lower the car approx 3/4 of an inch without sacrificing preload or shock travel. Mounted everything up and dialed it in at -1.6° camber and some mild toe-in.
Car drives so much better with the new setup (Vogtland, ST swaybars, camber tops, excentric inner LCA bushes.
Next thing needing attention: I have a slight slack and clonk when accelerating/decelerating somewhere in my drivetrain. U-joints are all good, diffmount has bees swapped to RT, engine mounts have been renewed. Hopefully I'll find the culpript. Let's cross fingers it's not the gearbox.
