Push rod rear suspension

[adamwatson]

I've got the narrowed RX8 rear suspension fitted to an MGB and next job is sorting some spring and dampers. Rather inconveniently there is a chassis in the way of running some coil overs in the stock place but I could fit a bit of tube through so I'm thinking push rods to inboard coil overs.

If I build it so the movement is as straight as possible on the coil overs is there much else to consider in alignment? I've kept the standard RX8 geometry/arms/hubs, does the angle of push rods, rockers and coilovers have much effect?

Thanks!

It's mainly in the geometry of the rockers. You can build in a ratio or just have them 1:1.. It all matters really. Everything moves in arcs so you have to think about that and design in rising rate chatiteristics etc as you go. Don't forget the strength and rigidity of the chassis is important too. Transfering those loads to somwhere they arnt normally going needs thought.
