Roll-bar...?

[ejenner]

Should I take the roll-bar out?

Have heard of people removing this. Any advice would be appreciated.

removing the front anti-roll bar will decrease understeer and give the car more neutral handling. depending on which alignment specs you have the car set up with you can get quite a bit of oversteer with this setup even. it will also give you slightly better turn in, as the front of the car will roll to the outside more and compress the outer front suspension more, due to the geometry involved this will result in increased camber on the front outside. desireable for sticking a corner. as the body tries to roll the rear as well the rear anti-roll bar will stop this and the car will set and carve into the corner. go too fast and the stiffer rear end will result in oversteer- the rear will tend to break first. however, in my experience, using stock alignment specs along with removing the front bar will result in basically neutral handling, with still a slight tendancy to understeer when pushed to the edge of grip. this assumes equal traction tyres at both ends.

Have to admit to not being too keen on oversteer. I've had three cases of unwelcome (unexpected) oversteer since I started driving. Ended up causing damage to the cars on all three occasions. Twice with a bent rear sub-frame and once with the sub-frame, gearbox, rear panels - various wheels were also broken in all cases. :(

Still - I think I'll give it a shot anyway :cheesy: see what it's like. Can always stick the roll-bar back in if I get scared... :wink:

Removing the front ARB will also improve the ride comfort from the front as each wheel becomes free to act independently.

being performance minded owners though we don't care about comfort, right? :)

The last semi-comfortable car that I owned was my 88' 9000T and that was three cars ago. My wife won't even ride in my SPG now because as she said
"Its too uncomfortable" Seems fine to me.

Ah the price for handling. :wink:

My car is very comfortable. But I have not changed the wheels yet. So I'm still with 195 x 60's. Anyone who says the c900 isn't comfortable just has to ride in a Ford KA for a short time (although it is often said that the KA is the most comfortable in it's classs)

My wife says the same thing to me but I just keep telling her its just my way of making sure she doesnt want to drive it!!!! :P AS you can guess that goes over well. On the serious note I would think that you would want to keep the rigidity in the suspension since over and under steer are both bad things (in my opinion). But hey always willing to explore better setups. :-??

Steve - from what I've read above it would seem the roll-bar makes the car understeer. Understeer is more predictable than oversteer and consequently safer - But not as much fun. :cheesy:

[stevehayes01]

Ok. I guess I have always been used to adding as much rigidity and stiffness to my suspension as possible with other cars. Now how does it affect the Torque Steer issues during acceleration? I may have to experiment just to see what the difference is. HMMMMMM! We'll see.

[ejenner]

kind of thinking the same sort of thing. (i.e. think I will give it a try also)

I like the bit about making the two sides operate more independently. So you can imagine flying out of a bend and the outer leading wheel will hang on longer because the expanded shock on the other side isn't forcing the leading wheel to adsorb that force. Instead the suspension compresses further and the weight moves right over onto that front leading wheel.

[Johann F]

Exiting a bend is much nicer without the ARB as you don't have to over compensate as the spring rate changes and tries to tighten the turn just as you are straightening up.

[ejenner]

That seems to make sense -

This is starting quite interesting... :idea
