Countach suspension

I'm thinking of two things that might be different

Wheels & Tires.

Extra weight and how it's distributed.

Any way you look at it a well sorted Countach corners like it's screwed down. Trying to optimize what it had when new oughta be enough. The claims that one model is better than another are largely subjective and are rarely based on side by side comparisons under ideal circumstances.

Be happy with what you have it's more than most will ever know.

 

And those two things alone are known to make a big difference.

But I'm not sure "Everyone claims" the Annivesario is best handling at all. In fact most S1 and S2 owners I have come across that have driven other Countachs think those are the best handling. Also, many Countach owners have no opinion on this subject because the only Coiuntach they have driven is - theirs!

And you are right, its all subjective.

In my own personal experience which includes all the variants including several S1 cars, the Annivesario handles best. Why? I'm not quite sure, other than the items you mentioned above, and perhaps some slight revising of suspension geometry mounting points etc. What have I to gain in saying the Annivesario handles best? Absolutely nothing - I don't even own one any more. But the handling differences to me stick out like a sore thumb, and I was reminded of this recently. They go round corners like they are on rails.

Hope U are doing well, give our Best Regards to Betsy!

 

I had a 2 level spinal fusion 2 years ago. Know how you feel........I'm still/back in physical therapy today. Have fun and catch up on all your Lambo stuff.

 

So true. To give a knowledgable opinion one would have to have:

1. Driven each variant preferably in similar conditions not years apart.

2. Be accomplished enough a driver to subjectively tell the difference in handling.

The first is easy to achieve and the second I'm not going to get anywhere near as all sportscar owners think they are masters behind the wheel

 

The tyres for the 25th and your car are the same. The rear uprights for the 25th are different,locating the lower arm in a different place.
The 25th car is FAT, like in over weight, we are talking about 3600 lbs or more here.
The LP400S weighs around 3000, my 87 QV weighed with a full tank 3460, now with the diet it went on, it is around 3000lbs.
The wheels on the 25th are different in looks, and I believe they are the same size front and rear, 8 1/2 x 15 front, and 12 x 15 rear.
I will look in my 25th owners manual to check that.

As far as handling perception goes, most of the regular posters here have exclaimed that the anniversary model is the best handling. Prior posts will no doubt verify that. So, ..... why does one feel that way if there is no mechanical change between these models?

Not trying to antagonize, just looking for answers.

What is the actual difference? If anything other than just part numbers?[/QUOTE]

 

This might help.

 

The so-called better handling of the 25th is result of other Tires and suspension settings which base on the newer PZeros instead of the P7.

I have overtaken the suspension setting on my QV and made it slightly more aggressive on the rear since the cars have a latent tendency to understeer at corner entrance.

I never saw a better handling car so far... for sure not those fat 25th.

What did you change your rear settings to?

I have only driven a couple of others. I agree that owing to the age of these cars there could be so many variables eg, tired dampers; tired tyres out of spec suspension etc that the only real way to compare would be to have two cars with as near identical tyres suspension etc and to drive them back to back. The wheels could be swaped to see of the ani ones are lighter and make a differnce etc

If the uprights are differently located on the rear of the ani where are they located? does anyone have pics to show the difference?

I think the cars handle nicely. They seem to be easy to drift owing to the thick sidewalls and give you a lot of warning of what they are doing/going to do. I have only pushed mine hard a few times on race tracks and roads. My general impression is loads of tyre squeeing and screeching before you run out of grip! My biggest concern is braking and stopping which is poor for this level of performance

Mike, here is what I got from my factory owners manuals for the 25th and the QV car.

25th, Wheels are the same except for design.
Front suspension Toe + 1mm
Camber -0 degree 15'
Caster +6 degree 30'

Rear suspension Toe + 3mm
Camber -0 degree 30'

Weight of 25th car, A FAT, FAT 1680, which is 3705 lbs. Add 2 200 lb people and you are looking at over 4000 lb. And people wonder why the brakes seem weak. The same brakes that were used on a 3000 lb car.

QV Wheels same as 25th except for design.
Front suspension Toe 2 mm
Camber 15'
Caster 6.5

Rear suspension Toe 3 mm
Camber 45'

Weight of car 1490 which is 3285 Lbs, with the same brakes as the 25th car.

Thanks for clarifying the differences Chad.

 

Have opened the track at the rear a bit, best was to fit Pirelli PZero C at the front, made a lot of fun on the track and road
