Lol... If by "mill" you mean "$29 Ozito angle grinder"

I like that info but it has me worried.

Yeah I can see why you'd need one

First thing to remember in performance and in general is springs give car height and shock control gives ride quality if done right.
 
A fast acting but well controlled shock with a light but progressive spring is the perfect combo.Finding it is the hard bit...

Probably the best I have heard off apart from Koni and Bilstein is pedders. Pedders springs and shocks from the reports I have seen are not as harsh as kings springs with standard type shocks (monroe etc) and the pedders shocks seem to be able to handle ok.
 
My wagon is running run of the mill shocks(can't remeber the brand but they are standard). When I had the standard springs in the car they are ok with plenty of understeer when pushed. I then bought a parts ute that had low kings springs ( not even superlow these are one step under standard height) that I swapped into the wagon. It was mainly to get a reading on the installed spring pressure of the springs but I haven't been arsed pulling them back out again. The install of the king springs alone reduced the understeer enough that the back started to get tail happy and I was then starting to get over steer. My tyres were starting to get pretty low( and very old) at this point so I go new tyres. I lost the oversteer cause the tryes gripped a lot more than the old tyres I had on the wagon but the understeer stayed away. BUT with installing the low king springs I have had a couple of instances of the upper control arm hitting the bump stop and bashing it sounds like I have just snapped the chassis of the car, with the standard spring I had never hit the bump stops. There is nothing wrong with my shocks, they still control the car quiet nicely but when it comes to harsh sudden bumps they can't keep up with the king low springs installed
 
So what does this blurb/rant/waffle mean. Good quality short stroke shocks are not just for handling and going around corners fast, they are for general motoring comfort and will help to stop the car from hitting the bump stops when using lower than standard springs. As a bonus you will be able to corner faster but that is because with a good quality shock like Koni or Bilstein controls the car better(Bilstein give a slightly harsher ride than Koni, I have been told this by several people independent of each other). That is what the shocks are suppose to do, so if you skimp on shock quality you are skimping on ride quality it's that simple.

Monroe are shit, you can have my fronts if you want to see exactly how much they suck
 
From what I've read you're better off going hydraulic rather than gas on an X series, apparently they have issues compressing the gas ones properly IIRC.

If it's gonna go through every guy in OzFalcon can we leave unfamilia till last?

When I last raced Mod Prods up here there was a 63 year old racer who raced an XD falcon.  He was as fast - if not faster than the fastest young bloke up here is a $90,000 plus VZ IRS commy.  I mean it used to come down to who got pole as to who would win the feature between them two.
 
Okay the old bloke had been racing speedway continuously since his late teens, but man that cart spring XD was fast.  Nice bloke - even if it was him that put my car into the wall and wrote off the original 76 racer......

Would he really notice the shelby drop? It doesnt lower the car that much but really helps with wheel position. Its just 2 extra holes each side, nothing more.
 
As for the template I only need it once so seems silly for it to just sit in my shed. Just use a 3mm drill bit through the jig, remove the jig and drill to size. That way the jig stays accurate and then pass it on, then we all can have shelby goodness.

Well consider it the ozfalcon shelby drop template. I will pull my finger out ( clean my finger before touching template) and get the job done so I can pass it on. Have to thank Crazy for his accurate drawing that I made my template from. Will take a pic of template when I get home and put a couple of pics.

If either of you blokes are interested I made up a drilling jig for doing the shelby drop. Its on my long list of things to do but after I have finished with it if you pay post (its 1 plate with 2 bolts will fit in post bag) its yours.

The Shelby drop is reversible... Just leaves a couple of "speed holes" is all.

Dick Johnson always said that his tru-blu XD was a very nicely balanced car, easier to sort than the watts-link XE.
 
Nath have you thought about doing the Shelby drop? I'd like to do mine one day.

If it corners like a race car it probably has to ride like one too which I'm not too excited about
 
Once everything else is sorted (and I'm not running urethane contol arm bushes anymore...) I might see if they do heavier springs - surely they would if you asked.
 
 
 
Hey Falcons went around bathurst, leaf springs and all so they can't be that bad at the end of the day.

Just your crossy telling you it loves you
 
If you find a way to fix it let me know... mine does the same.

The nut behind the wheel

There is nothing wrong with a twin A arm suspension set up.  Yes is it old tech but remember a few years ago in V8's when the crapadores wanted the ford Twin A set up (and got it).  They wouldn't be screaming for it if it didn't work.
 
The xf is a seriously good car to punt around at speed when set up for it.  One of the fastest cars in Mod Prods atm is an XF Falcon.  He is up against all the modern IRS big HP cars, but the big XF keeps on winning.  And I am talking Big $$$ shows - not country track feature wins.
 
Many years ago I spent 6 weeks at a driver training facility in Brisbane (Mt.Cotton).  We had an old XF, a VL turbo, first series EA and VN commodore - yes it was that long ago.  The easiest car to control around the skid pad was the XF. Everyone agreed, there were 26 students and 4 instructors.   Even when they fitted the bald tyres, put down the diesel and turned the sprinklers onto the track - the only car everyone could punt around in a continuous slide was the XF.
 
That day was one of the best days I have spent in a car and the memory of how the bog stock XF drove stayed with me for a long time. How long.  Well 18 years later when I wanted to go speedway racing - my weapon of choice - the trusty old XF.
 
I would be giving the dampening a tweak to the firmer side just to see if it takes out a fraction of the roll and improves the feel, but really with a 650lb spring it is never going to corner like a race car.  It will however be a very good compromise for a spirited road car.

You need a new set of fuel injected wheel nuts

The double over head junker pumper needs to set at .000002 lash at 27.5 degrees before top dead center, with the engine cold.

I was going to say washer fluid is too old

Needs a new diff.

My engines making a noise what's wrong with it?
