I was talking to Taka Ono and he was telling me that the 370Z is really stable and falls out of a drift easily.  It also gets a lot of traction out of the turns and doesnt go sideways as easily.  He said the 350 drifts a lot easier.  This is what we predicted in our suspension article.  Good for track driving and general driving.

Well, with less antisquat in the rear it isn't a surprise. I would like to run a stiffer spring in the rear of the Z33, but throttle application has to be done carefully in mid-turn as it is. I'm really thinking of a rear subframe swap in the future, with SPL links. I wonder if the front subframe will bolt up to the Z33 chassis? Personally, I don't have an issue with the front's trick split lower link where kingpin changes dynamically with steering input, but I want to deperately employ the 370Z's beefier knuckle and hub. Relpacing front hubs and dealing with pad knock-back is a pain. Plus, I imagine the Al subframe would shed a few lbs over the Z33's steel unit.

Will (truly wishes he had the time and cash to custom swap the front subframe)

I work with Steve Mitchell quite a bit and what you propose in the rear is exactly how his car is set up, a G37 rear subframe with SPL links.

For my personal 350Z time attack car if it ever gets worked on, I plan on relocating the longer stock links to reduce antisquat and to have less of a toe-in curve and to run slightly more static toe in. I think this might have a more linear feel to how the rear responds.  It ends up being about 12 lbs lighter this way as well due to the aluminum subframe.  I think for this car I am going to ask Eric Hsu to team with me, he handles the powertrain development and I do the chassis with Steve and John McNulty handling the aero.  This would be the low buck tuners dream team.

Steve and I have both looked at the 370Z knuckle and hubs and there is no easy way its gonna work.  Our latest thinking is to go to a die maker, anneal and weld the hell out of the hub to build up material, then solution heat treat it and remachine it for the larger hubs.  Whew.  It still won't be as beefy as what the 370Z has though.
