Has anyone tried s12 front struts on an 810? the springs will be too big from what i can see of the pair i have but the brakes are a nice upgrade.

S12 bolt pattern not compatible with 810 knuckles but I wonder if some clever adapter / bump steer spacer could be turned up, using flush allen bolts etc to adapt the two. S12 knuckles are not likley to have the right ratio/ackermann, but maybe C32 ones would be, getting into the realms of hard to find bits now. S12 brakes need 15 inch rim minimum as well.

Well the pair i have measure 80mm on centre of bolt holes, which going by the other thread is right? I've gone ahead and measured them up anyway and the struts themselves are 40mm shorter overall and inserts are 30mm shorter than the 810's ones.  I'm not going to work until 11 today so will have a fiddle this morning. |

So......... They do fit, kinda. The springs (as i thought) are too big (170mm compared to 810's 150mm), there is enough room to try them for fit but the spring hits if you turn. The bolt holes are in the correct place 80mm on centres, what not right is the locator. The 810 one is 40mm the s12 one is 54mm. So you would need a bump steer space with a 40mm recess in bottom and a 54mm lip on top.  My wheel now sits approx 10mm further out than the standard. Ride height wise its currently about 10mm lower. But this is due to how hard the springs are, they barely move under weight of car!! Going by the fact they don't actually fit in the turret this isn't a problem as they will get the chop anyway. I will add some pictures of it all later on once my phone has charged up. |

interested to see how you get on.  oh. and them bump steer spacers are not a close fit anyway so i wouldn't worry to much about that. |

So i spent an hour or so on this tonight.  All ready and waiting for the bits (and a method of getting the 50mm nut undone) to arrive. One thing i did do was cut the old platform off using a hacksaw cutting right next to the weld and you'll know when you have cut through as it will look rusty at bottom of cut instead of fresh steel  |

have you measured the stub axle to strut angle? also, how long are the struts? from the flat lower mounting point to the top of the tubes

they will fit on but it will make the car have + camber, I have C31 (same design at the bottom) on one of my 810's and it has caused this (will be changing them at some point)

will adjustable top mounts not help?

the standard old Nissan stub axle to strut angle is 10degree. so interested to see what these are. the pic posted doesn't look far off of these late 280zx legs which have the standard 10degree angle  |

will adjustable top mounts not help? not really, there a right pita to get lined up due to the difference in the hole sizes, bolts spaces are the same (think only 240z had different bolt spaces iirc) I did fit them to get bigger brakes and vented discs. On the 200b the + camber don;t affect the handling much other than when partking (really heavy) think it's due to the 810 haing the 4 link live axle rather then IRS Another think to watch is the left hand spring on a 810 is longe than the right hand one |

I'll be getting some spacers made up to sort out the location issue as to me the bolt holes have a fair amount of slop in them and you would be relying on the strength of the 2 bolts unlike original where the locator takes the strain. |

from the side by side pics of the 810 and S12 strut bottoms, it looks like the wheel hub face sits much closer to the strut. i wonder how hard it would be to measure that? S130 hubs also sit closer to the strut then on "normal" legs as well.
