Chassis development has moved on a long way since the williams, as has tyre technology. Youd be surprised the massive difference that some chassis geometry changes and damping/springing rate make. And im not talkign about simple tracking and camber.
Is it possible for such small changes on newer cars give the same sort of changes that the huge changes the Williams did from the valver setup?
Im not having a go at the trophy Id imagine its superb Im just intergued.
I know its not a truly fair test but how far off is a 172 with coilovers like a 182 trophy or has the trophy dampers relay show there extra costs off well?
If you really look into it, or understood chassis geometry in its entirety, which is a multitude more complex than engines, you would see that there has been no small amount of changes. The williams has a wider track, some different damping and springing, very minorly different scrub radius, altered SAI because they are using the same top pickup.
Compare that with the changes on the trophy which would be, wider front and rear track, altered scrub radius/caster offset/SAI, ligher wheels, lowered 30mm in terms of actual ground clearance, stiffer springing and damping, stiffer damper bodies with larger reservior to reduce overheating through hysteresis, beefier steering hubs yadda yadda yadda.
Buts its not about how many components you change, but rather how well as a system you get everything to work. What do i mean by that? Well you ask how far off is a 172 on coilovers? well, depends.........the majority of coilovers available to road users for under a grand are, well....sh*t. Secondly their damping and springing are calcualted along the lines of 30% stiffer and harder. Thirdly, people playing with their dampers tend to adjust them in poor manners because they dont know better, and its not their fault really.....dampers which are rebound adjustable have no effect on damping properties, but rather how fast the shock recovers. Wind it up and it takes longer for the shock to extend again, giving the impression that the car has less roll. Which is bad because the shocks can run out of travel for the force of the spring compression, loose damping ability and be practically useless on anything but smooth tarmac.
at the end of the day, its faster...whether most people can realisitcally drive up to the level to notice it is another thing, there is a reason why test drivers are rather good at their job lol.
