roll centers, rear uprights

Hi guys,
Here is some specs on coil sprung chassis.
Front .camber=0
caster =3*
kingpin inclination=11*
toe in =1/16
no of coils =10
coil dia =4.1/2''
wire dia =0.5625
spring length free =11''
spring length fitted=10''

Rear camber =2*neg
no coils =8
coil dia =4.1/2
wire dia =0.5625''
spring free length =11''
spring fitted length=10''

Ground clearance =6.1/2''
Track front =55''
rear =54''
Tyre size =185x15


185x15 uck. 289 only got 6'' rims, hence different track
S.C. 7.1/2'' all round. Some were lucky to get 9.1/2''
Competition early 6.1/2'' and 8.1/2''
late 7.1/2'' and 9.1/2''
Cobra wheels have 3.1/2'' backspace I am told.?
Rear camber neg 2 degrees makes it a little harder to calculate hub to hub spacing.Allow for hats and spinner adaptors if required.
Front camber=0, K.P.I.=11 degrees. If you have bottom arm sorted draw a line up at 11*.Top arm angle to obtain desiered R.C. ,lntersection is top ball joint.
This K.P.I. line should meet the ground level line at track width, wheel centre for 0 scrub radius.
Cheers
