Reply With QuoteDefinitely use rose joints if you go equal length, and different bolt positions on the boxes so you can play around with squat and anti-squat by changing the arm angles.
If your go equal length use rose joints.
Ps - I would be leaving the lower arms stock (these set your wheel base) and run adj upper arms to correct the pinion angle.

To be honest I don't agree with that, urethane bushes are perfectly fine, they are stiffer than a stock rubber bush but not as harsh and damaging as a rose joint, yes it is a track car but why make something harsh and unenjoyable when it isn't nessiscary, I really enjoy the comfort that my car has on the track
If its got a gutted interior, then having rose joints (increasing NHV or NVH) will be neither here not there.
it does increase the road transmitted noises, but, you have a helmet on... it doesnt add clunking or anything link that... its more like just turning up the ambient noise.
the rose joint gives you the most direct link between the driver and the road.
ive ran them in street cars and it hardy makes a difference in noise, but maybe im just deaf..
thats why serious race cars run nothing else..
I'm not talking about noise, I'm talking about bumps and shudders from driving over rough surfaces/undesirable objects etc, it transfers the abuse straight into the chassis stretching bolt holes and cracking welds etc, high end motorsports can afford a new chassis etc, I would like to make my car last as long as I can
I plan on crashing mine before it wears out.
Right on man! Hahah
With an equal length setup there shouldn't be any massive load on the arms or mounts though, as they are there to pivot only and there's no bind or twist acting on them either. The shocks and springs would take almost all of the force from road imperfections.
you would get pulling when you yanked the old handbrake and some push when you kicked the clutch... but really.....
F it, just run them in an equal length, happy dayz haha
There is definitely much load on these, that is what these arms do, they are designed to stop the diff from moving forwards and backwards and at the same time they allow it to move up/down, I don't see how a shock is going to stop the load of the rear wheels hitting a sudden incline (ripple strip edge) the forces will be transferred straight through the arms, through the rose joints and into the holes/brackets/welds that the arms are bolted to, I am not saying that rose joints are stupud or a bad idea, I am just saying that there is much that is overlooked when people do this sort of modification
