Does anyone know the original sizes of springs from the AU1 Forte'?

InfernoSR · 15-09-2007, 06:34 PM

I should also add:
1. Whats the length of the AUI forte' shocks all round?
2. Whats the length of the AUI XR shocks all round?
3. Whats the length of the AUI XR springs all round?

4. Whats the factory height of the AUI Forte'?
5. Whats the factory height of the AUI XR?

Mate have a look at this web site http://www.trueblueford.com/aufalcon.htm I use it a lot for specs on the au hope it helps.

shocks are all the same height.

Forte spring has 11 coils.

XR spring has 9 coils.

Ghia spring has 13 coils.

It's not just about spring length, but depends on the number of coils, and the wind, the thickness of the spring etc. Essentially, the number of coils determines the comfort of the spring, while the "squishiness" rate and thickness of the spring determine how much the spring compresses. If you cut approx 1.5 coils off the Forte spring, you end up at XR height, which means the XR spring is stiffer as the lower number of remaining coils (9 vs 9.5) results in the same ride height, but a firmer ride in the XR.

Why do you ask?

Well my AU is about an inch lower than an AU XR8, another set of springs came with the car and are alot longer and thinner... I'd like the set the height to STD XR spec height but need to know at what point to start with...

I can start the ball rolling for you:-

XR FRONT springs are 15 1/2" (395mm) in length.

This measurement is from an XR spring that my brother has yet to install.

Are the rear springs all the same?

If so I can get him to measure those tomorrow.

InfernoSR · 21-09-2007, 01:07 AM

Thanks for that mate, yes please to the rear springs measurement.

Sure...

I just checked again and he followed the original email with another which states that the FRONT XR shocks are 415mm from centre of bolt hole to top of "tube" excluding "plunger rod".

I guess he's talking about the body of the shockie.

I'll confirm that for you and report back when he replies tomorrow.

Ok, here's what I've got:-

AU XR Front Spring = 395mm
AU XR Rear Spring = 325mm
AU XR Front Shock = 415mm (Centre of bottom bolt hole to top of reservoir tube i.e. excluding piston rod etc - http://www.eshocks.com/Kon_AllB.asp - so we're on the same page viz descriptions)

He hasn't bought rear shocks yet so can't help with those measurements.
