Lightbulb My mod. 960...the socalled 966 WVK

As you can see I have a modified a S960.
And I would like to know what other people think about it.

useless post like: "won't work on a non bumpy road" won't be taken seriously.

UNLESS you can give some feedback why you think it won't work!

So, Why do YOU think it work or does not work?

What kind of expectaions do you have from this modification? It seems like an interesting mod. I would imagine better side to side weight transfer, but then that might cause conflict with the rear shocks>?

Default Opinion

If I read the pic correctly then the chassis will be raised in roll instead of dropping- if the shock was mounted on or above the inner upper pivot points it would work as a damped arb. May turn you into a nervous wreck in a full throttle sweeper with a few scattered one wheel bumps. (both configs perhaps)

This is just an observation (never tried it)- so do not stop trying things even if they are unconventional. If it works for you it is right - no matter what the theory.

Default modified rear suspension

I think this modification will tend to keep both rear tires on the ground and this may induce push.

Have you tried this out yet? If so, how did it work?

with inducing push you mean understeer?

I tested at various tracks across europe, In Paris (France) it was not giving the result as expected, can't find a good reason for it...
the weekend after Paris I tested it in Fiorano (Italy) which is a super fast, average smooth but with huge levels of grip.
I almost had tractionroll problems there... which are in europe quite rare!

Back here in The Netherlands it seems to work quite well on most tracks, hugely more grip (depending on set up of course) which makes the car easyer to place!

Default modified rear

Yes. push = understeer.

I would think that the modification you did would really work great with a rear differential because you are keeping both rear tires on the ground and the diff would not unload due to one rear tire being up in the air while turning.

In the USA the tracks are frequently smaller with tight turns and having both rear tires on the ground while turning would create understeer unless a rear diff was used. The FPS diff would be perfect because it allows the diff action to be adjusted externally.

And thus more grip

the problem is that a diff would not fit in a 960 rear end...


I think 2 that a rear diff would make it drive even better but on the other hand you get more mass to accelerate wich result in higher laptimes :'(

Well, lets give it a shot......

As the picture is not completely clear to me, I might change my opinion after this weekend, where I should be able to see it in real live, or not Peter......

To me it looks as if the body mount is not directly on the suspension arms anymore, but on the chassis, this gives less downforce, because the suspension needs to pass it through to the wheels.
Also it looks to me as if the "spring roll bar", doesn't do much, it barely moves I think, which tells me that running the car without it, give the same effect......

So, Why do YOU think it work or does not work?
I think the key question (if you are racing on the NK-national level) is:

DOES IT MAKE YOU FASTER? (related to lap-times).

Fact of live is that Serpent spend several years of desiging the 960 with specialized equipment (hard & software) and is still improving some aspects.
In order to understand this development I raise my question":

"What was the reason for this modification?"

CU this weekend

In F1 they also have a 3rd spring to keep the car from rolling, but a F1 car has a diff.
If it fit's you could try it in a 1/10 car.
But i think it's a great idea, good thinking.

Did you see the car in action this weekend and if so, what was you impressions of the Mod??? On a positive note though, this is a hobby and new things are tried all the time... Somethings work and somethings don't... But that's what makes this hobby so much fun... .02

I had no change this weekend to see the mod......

I did see the car in action this weekend, but can not give you any comment on the mod.....
I used a new engine this race, so some extra attention needed there, also it just wasn't my weekend, missing a top 4 place directly into the final by just 0.5 Seconds, then halfway through the semi which I was then leading by a lap, I overtook a backmarker, but went off, and lost my INS-BOX, which costed me about 7 laps before I got back on the track.......

Better luck next time....
