The point I was trying to make (With or without the one being carried) is that belting a kerb to a degree is analagous to the random brick on the road the solution to which is the pretty much the holy grail of active suspension. You want compliance at that point.

Are your spring rates and bar rates higher?

They both are.

My OEM spring rates are 5.9kg / 6.5kg F/R. The Flex run 12kg F/R.

Not sure how thick my new swaybars are, but they're definitely thicker (about as thick as you can get, apparently) and solid instead of hollow.

Given how skittish the car is with 12kg springs on the street, if I don't find the car easy to drive on the track I'll drop down to a 10kg spring. Should that still not give me the powerdown I want, I'll put my OEM rear swaybar back on.

What car is it to have higher spring rates in the rear? The big cast iron engine is up front so woudl expect the higher spring rate to be at that end.

My engine is alloy. Its a 350Z.

Considering my car's weight bias is to the front, and my spring rate bias is to the rear, I just cannot for the life of me explain why the damned thing understeers so much in stock setup.

Caster and camber, the way Nissan designed it

Understeer is good for the Wallies

When they rush up to a corner too fast, so understeer is better as it scrubs off speed

Oversteer and Wallies don't mix, flying off backwards at undeminished speed is not good

:( cheers :no:

There's no doubt that most of the understeer is engineered in. Getting rid of the staggered tyre sizes, and different swaybars, cured most of the understeer.

Probably the best "bang for buck" handling mod I did to the car.

      What brakes on R34 GTT(Europe)

      I would just put EBC back on the "I would not use their stuff" pile and move on.

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
