"Improved steering response and adjustability."




Are any of these parts worth it? Or are they just extra crap to put on an s2000?

BTW, do these parts decrease the turning radius? If not, how do you decrease it?

 

The rear control arm is pretty much the same thing as the TC designs anti-bumpsteer kit. Feel free to read the many discussions about bumpsteer elsewhere in this forum.

To decrease the turning radius you basically need to shorten the wheelbase (or put in rear-wheel steering), so the answer is "no".

 

I was under the impression that if you get wider fenders, wheels spacers (using stock wheels), and adjust the tie rod, you can shorten the turning radius.

IM Assuming this can also be done by playing with the caster. But I dont think messing to much with the caster will help the handling or stability.

 

If you add the capability for more lock to the front wheels, you will decrease the turning radius. But these parts aren't going to do that. And if you are designing the car from scratch, adding rear wheel steering or decreasing the wheelbase is a more efficient way to do it.

 

where did you hear that?

"playing with the tie rod"? you could toe out one side and tow in the other, that would decrease the radius in one direction

And doesn't a wider stance/width increase the turning radius?

 

I dont know. But it seemed logical that with the wider fenders, you could get the tire to turn more outwards, therefore allowing a shorter turning radius. Does it seem illogical or is it too complicated?

 

That's "adding more lock".

 

and what exactly is the end result?

 

OK, back to square 1:

No, these parts will not decrease turning radius.

 

I can read. But what about my previous statement, which you replied to by saying: "thats adding more lock" ?
