diff done and in the car just awaiting new tail shaft

Custom made adjustable upper trailing arms (btw adjustable TE Cortina uppers will fit a stock sigma diff, just need to enlarge bolt holes)
Also looking into making some weight jacker lower arms

Viking double adjustable shocks are on the way, pn B217

Wow, this is serious Mick.
I love what you're doing with this.
One day, maybe you'll be able to show me what it'll do ;-)

Cheers Dave

Above pics clearly show what it does most of the time but basically all it does is fill a spot in my shed while eating cash :(

Nothing really exciting happening, have changed a few things in the past 3 months as a few thing were at their limit

Changed the coils to ls7 units as the D585's were thought to be over dwelling and shutting down at 4500rpm, turned out to be the CAS air gap 8o|
Swapped the Bosch 775 (astron 2.6, HSV 5.7) injectors for some 650cc Siemens injectors
Put in a new custom grind cam, it was WAAAAYYYY under cammed and not making the most of the CHI heads
Got some 4 into 1 headers and twin 3" exhaust made, Used Pipemax to get optimum tube size/length, collector shape, and position of Y pipe/mufflers etc

Will be going to CHE in the new year for a tune, hopefully it'll crack the 500 mark

Next year I'll be making height adjustable lower trailing arms and fitting double adjustable shocks and a 6 point roll cage

Our engineer uses NCOP so going by these guidelines I can fit a 4 point rear cage that is either welded or bolted in place so long as it meets the NCOP head clearance occupant entry/exit guidelines, front section is not allowed on the street though provisions for a removable bolt-in front section is permitted

I don't know the rules of other motorsport governing bodies but ANDRA now allow bolt in cages in cars that are capable of an 8.0 or higher ET providing all bolted joints follow ANDRA guidelines

We've not long finished a cage (and much more) for a street driven Vortech blown 430ci Windsor powered LX Torana that will hopefully run in the 8's
