Proper Lusso ride height?

Empty gas tanks.......

Marcel Massini

 

I don't know if any, including 250 GT/L service manuals have ride height specs (like the manual for 365 GTB/4 & GTS/4 does), but I imagine anyone with reasonable experience and understanding of suspension geometry can figure it out.
I mean it's not rocket science after all, just math and taking measurements/weights, etc, and if some 8th grade dropout without any formal (automotive or mechanical) engineering background can figure things like this out in variety of vintage cars that never had such specs available ...

 

I recall on a gtc, when we finished resto on the car - it was riding high in the back - then we add 3/4 tank of gas, spare tire and a tool kit and i think that added 600 or so lbs to the back end - brought the ride height right in line!

 

That was a really heavy tank of gas, especially at 6.3 lbs per gallon. Alternatively, a very heavy spare or tool kit.

 

You may want to check your math or notes.
Unless that GTC had an unusually large fuel tank and/or tool kit, I’m not sure 3/4 tank of fuel, spare tire & tool kit adds up to anywhere near 600 lbs.

 

From the SEFAC homologation certificate (with full tank of fuel):
Incidentally, correctly stocked tool bag and spare wheel weigh about 70lbs.

ok ok.....math check to be done, however the point is add all the required weight to ck ride height!

 

When I used to corner balance my 911 race car (yeah, yeah…sacrilegious to own a Porsche race car and discuss it on here), I would add a full tank of gas and sit in the drivers seat with all my race gear to ensure we balanced the car in full race trim. Same when doing any alignment work. Same with street cars…put drivers weight in the drivers seat and include all spares/tools, etc. as it will be driven on the street. The level of gasoline in the tank(s) is subjective to some degree unless the manual states to do alignment at full load (my opinion anyway).

So whether Ed’s math is correct or not, the concept is certainly right!

 

I'm fairly sure Ed's math is off, as 365GTB/4 full tank of fuel (+/- 34 Gallons) weighs about 200 lbs (3/4 tank would be about 150 lbs), spare tire with wheel about 50 lbs and tool kit about 25 lbs and all expected to be included, along with the weight of two passengers when preparing & setting the ride height & wheel alignment on one.
