Hey everyone,

So apparently through my research, I found you can upgrade the handling of the F-Type by using an aftermarket sway bar from an XF.
Here are 2 links about it. https://www.jaguarforums.com/forum/f...nering-143921/ and here https://www.jaguarforums.com/forum/x...pgrade-141963/

I'm curious who else has done it? How were the results?

 

You have to be deliberate in your use of "handling". What are you goals? Do you want to be able to take corners faster while making overall ride harsher? Do you want car to understeer or oversteer?

Changing sway bars to a stiffer setup will have following effects: a) ride will become harsher, you will feel bumps and bad road more b) reduced body roll and improved cornering grip c) depending on front vs. back swaybar ratios you can induce more oversteer or understeer; generally big front sway bar will make car understeer at the limit making it harder to recover.

 

I've actually bought both of these but not installed them. Hoping to reduce some of the nose heavy understeer from the V8.

Have delayed installing them for the moment though after reducing the weight of the car from the 2 piece discs, forged rims and lithium battery. If you can hang on a couple of weeks, I'll post up my impressions.

Also, I think the front sway bar is largely a waste (only difference really being that it's solid vs the stock hollow bar). The rear bar should reduce understeer though, at the expense of more snap oversteer.

 

@SinF Great question. Thanks for asking for more specifics.
I'm simply looking to take corners faster with less body roll.

 

@ss23 I can absolutely wait. Do you have a coupe or vert?

 

Snap oversteer is really dangerous especially when driven by a novice driver. This is what gave early 911s "doctor killer" nickname.

 

You can change alignment setting to alter handling based on driver ability increasing or decreasing understeer, and oversteer. I align several track cars based on what the owner feedback on handling is. Give them a alignment sheet so i know where i set and tell them to make notes on handling and changes so tweeks can be made accordingly

 

Anti-roll bars / sway bars etc. are designed to increase the resistance to travel on one side of the axle when the load between the wheels differs. This means that if both wheels need to travel up at the same time, it will be neutral and not interfere. This applies to anything that both wheel cross at the same time or any weight transfer (such as dives due to braking). Contrary to what has been written above, it will not affect brake dive.

Changing suspension settings, from angles to actual components, is not a one size fits all, and in general the average driver will not feel any difference by swapping the anti-roll bars. They come into play with very aggressive driving and they work in tandem with the proper spring stiffness selection. Unless you track your car or Autocross it, you will not feel much of a difference and if you do, it's just one piece of the puzzle.

 

Snap oversteer or liftoff oversteer is when you cause a sudden shift of the gravity vector towards the front end of the car and it's usually due to throttle release or braking. A novice usually lacks the experience to modulate throttle and or brakes correctly and this usually ends up with a slide off course. However, while this thread debates the merits of swapping suspension hardware, it is always a wise choice to get intimately familiar with the cars behavior and learn where the limits are. Gentle does it, always.
911, just like any RWD rear engine cars are far more susceptible to this than front engine RWD cars.

 

What specs do you use on the awd f-types? I’m Curious to see the changes.

 

I installed these on my car a couple of weeks ago. So far, my feedback is relatively positive, it does reduce the body roll in cornering slightly. I would not describe it as a significant difference though.

I probably would not do it again considering the cost of the sway bars plus installation
