Anti roll bar won't go on (rear) - help asap please
Can the ARB be fitted with no weight on the rear suspension?
I've loosely bolted the bar & U brackets to the car, and the droplinks to the upper arm brackets - and the holes at the ends of the bar will not reach the studs on the bottom end of the droplinks (they're about 1.5 inches apart). They might reach if the upper arm was moved up to its normal ride height (or they might not). I've got the bar this way round - long straight on the LH, short straight on the RH. Here's Rimmers diagram for reference. https://rimmerbros.com/Item--i-GRID001546 Last edited by Blink; 8th November 2019 at 12:28.. |

I left my bolts lose so I could slide the anti roll bar left and right so I could get the drop links in. Leaving it lose I'm sure also allows it to swing down/up. I cant recall but I dont think I had my wheels on the ground when I assembled the anti roll bar but did when it came to tightening and torqueing up. Drop links are handed by the way but I don't think you can fit them the wrong way round. Short straight is to the off side.
Were there problems with upper arms and the posts for the drop links being in the wrong place? macafee2 Last edited by macafee2; 8th November 2019 at 12:59.. |

Yes (and no). The drain holes on the upper arms are too close to the edge of the spring cup. The isolators have to be modified so the cutouts line up with the holes. I'll try and find the thread on it. |

You can see that the ARB is touching the upper arm, preventing it from swinging up towards the droplink stud. And that's with the U bracket bolts nowhere near done up (there's still thread showing between the subframe and the U bracket). If the upper arm was moved upwards, the hole in the ARB would be able to get closer to the stud - but I'm not sure it would be enough to close the gap completely. |

Position of droplink bolt hole on upper arm
Pic below - new arm and old arm side by side.
I didn't actually measure them (should have) but I think distances A and B are the same on the new arm as they are on the old arm. In other words, the droplink bolt hole has not moved to the left or the right. If it had done, the end of the roll bar would definitely fail to line up with the droplink. |

Btw, the only other thing is this roll bar is the uprated version RGB101062UR from Rimmers. I think it's fatter (23mm?) than the old one but otherwise the same shape and length etc. Rimmers' invoice has the numbers RGB101062UR and RGB000081. The web page says RGB000081 is the bar for the ZT. I asked Rimmers about it and they said it was ok for the 75. Very confusing! Off to fit the backplates & hubs now. |

Jack up the hubs whilst the car is still supported.

combining with clf's reply, would just fitting the damper be enough?
Sorry I did not realise the damper was not fitted in my previous reply. Do put the car on 4 wheels before torqueing up the bolts etc macafee2 |
