Default How to decrease the Turning radius(Any Possible Mods)??

Hi technical Gurus.
I have a Petra and have always felt bad about the Turning radius of this car w.r.t. its size. For the people who dont know its TR, Its 5.4 mtr and makes some easy U turns difficult ones.

Is there a way to make a after market modification to decrease TR without compromising on the stability of the car. If yes, where can that be done in Bangalore and how much will it cost.

Not sure if this is a valid section to post this thread. Request Mods to put in the relevant section.

Thanks in advance.
GD

Well, It would be a costly affair . You will have to change the steering box , drive shaft , plus the ball joints incase you want to try

In my opinion its not possible to change the turning radius of a car. Even if some modifications are done to achieve it, it wont be worth the money

Most cars have a steering stopper. Remove that and see how much more it will turn. Now if the tire is hitting the body, then you need put a smaller wheel and tire, re-position the steering stop and viola you have more wheel cut. But you also need to ensure you have enough rack travel.

For God's sake don't tinker with an Italian design if you love your car.

Taking it from here..how about cutting extra teeth on the rack? Not going overboard but say around three more? From driving position, one tooth on right and two teeth on left?

Tech-heads can throw lights and tell my thought is all rubbish. It will be a learning anyway.

Now that's getting real complicated. First there has to be enough metal between the end of the rack and the inner tie rod. Now, tf its a power steering you have to make sure the hydraulic piston can also travel more. Not a project for an amateur for sure!

Looks to be a complicated & costly affair, Its better I live with the existing Turning Radius of the car

Yes greatDrive, it is a complicated affair and costly. I love the longer turning radius . It adds to creating traffic!

Are you serious moral? I seldom take my adventure to city, owing to longer TR. It is the only drawback of fiat cars.

Larger turning radius seems to be a drawback with all Fiat cars, including ones from Alfa stable. I remember having read reviews about Alfa 147 and people complaining about this. Yes, making a U-turn in a Palio is a real chore. Most of my U-turns end up being 3 pointers, more so when you compare Bangalore's narrow roads.

In my opinion, it is better to live with this problem than trying to rectify it. It definitely is not worth the money and effort to make any modifications.

it would probably reduce the turning effort at the expense of driving comfort
