Tarmac Rally Stratos Build begins

Good video, Porsche 911's similar weight distribution typically have rear RC 12-15" above ground.

Really, That sounds very high?

Interesting video.


For the rear wishbones, do you have alternative inner mounts?


One thing to watch when setting up the rear suspension is to ensure you still have enough clearance for plunge on the driveshaft/CV joints. Playing with camber of wishbone angle can affect that. Though given your other attention to detail, I doubt you would have issues with that.


The short wheelbase certainly contributes to fore-and-aft weight transfer, and the strut-type rear means camber change happens in roll, so nothing is ever ideal. The high C-of-G with the V6 doesn't help either, can certainly feel that weight sitting just behind your shoulders

Yea Rear Wishbone Inner Mounts are a nolathane Bush from a Holden Commodore Pan Hard Rod, Its just a good sized bush, easy to get, used them for a long time on the Alfa


All good on the plunge of the driveshaft, but good point


Yea the Short Wheelbase definitely makes the vehicle far more sensitive to this sort of stuff, and as you say there are a lot of compromises with Strut Type suspension, Roll Centre Migration is a big issue, particularly with such short bottom arms
