S2000 Question(s)

[c8nay]

I need some information on a few things regarding S2000 spec cars and I thought what better place to ask than you knowledgeable lot.

Can rear wings (or any front splitter) on the cars and gear ratios be altered for each circuit or are they fixed?

There may be a few more questions in the future if you don't mind answering them!


Thanks

Wing angles can of course be altered and gear ratios as well. Splitters I assume need to stay the way it was homologized (sp?) but Im sure someone here can confirm/deny that.

[nickyf1]

oh, I didnt know the rear spoiler could be adjusted, I always thought it was fixed like the BTC-T cars

[stedevil]

Well, that is usually Thompsons "secret" weapon. Put the wing flat and get that little extra speed down the straight allowing him to pass. The real trick is how he manages to hold the car on track through the twisty parts. Not too easy to copycat (or everybody else would also do it).

Sounds a little bit like the SEAT TDi conundrum in BTCC last season. They had more pace on the straights, and then had to defend during the corners.

[stedevil]

Yeah, but they did it with more engine torque (+ less penalty weight than the WTCC TDIs...) and suffered in the corners due to a heavy front. Tommos way makes the back end suffer (and is probably only suitable in a FWD car).

[Pettersson]

The frong splitter can not be changed like in super touring, it has to be fixed. I don't know for 100% about gear ratios on the FWD cars, but on the BMW's you can change the final drive in the rear axle to suit different tracks. It should be the same for FWD cars (changing final drives) if I haven't missed something important. It is however not possible to fine tune every gear at the track as in video games and such. But you can shift gearboxes that has different gear ratios to suit different tracks.

As far as I know gear ratios can only be altered before the scruteneering.

[nik]

weve changed gear ratios during the weekend before, and altered the rear wing in quailifying and between races e.t.c

[c8nay]

Thanks for the help guys. I'd heard before about rear wings being fixed, but as mentioned wasn't sure if that was an S2000 rule or not. I read through the technical rules about the gears, but as expected its not casual reading!

[crmalcolm]

So, if I've read this correctly;

Front Splitter - Fixed, not adjustable.
Gear ratios - Changeable.
Rear Spoiler - Adjustable.

Or have I missed something?

[Aslak Vind]

Then ofcourse you have the whole suspension to adjust.

[crmalcolm]

And engine management, fuel mixture, ballast position, tyre pressures, etc....

Well the front splitter as such cant be adjusted but you can ofcourse change the ridehight on the suspension and thus getting lower/higer splitter.

[crmalcolm]

Wouldn't altering the ride height to anything other than the minimum be disadvantageous?

[Matt]

Nope. If it's too low, you'll hit bumpstops. :P I think it would be slightly advantageous to raise the car a bit on street courses, or tracks with high curbing. Wouldn't wanna smack the sump on the ground/curb because it's too low!

[Aslak Vind]

Given wet conditions, you would use a soft setup. That would make the cars rideheight move, and then if you already use the lowest rideheight you are in trouble.

[JMeissner]

The S2000 cars have a rather high minimum ride height. As far as I've understood, teams often run the cars at the minimum ride height, at least in the front.

[nickyf1]

I know that running high rideheight on the rear reduces lift off oversteer, so that would be a FWD thing.

[stedevil]

Well, the downforce generated from higher ride height in the back would of course be beneficial for all cars, F/R/4WD, especially in high speed corners.
